The next version of the prompt-based AI image generator, Stable Diffusion, will produce more photorealistic images and be better at making hands. SDXL 0.9, a follow-up to Stable Diffusion XL, “produces massively improved image and composition detail over its predecessor” according to Stability AI. The announcement appeared in a since-deleted blog post and was reported byBloomberg.

Stability AI describes the new model as providing “a leap in creative use cases for generative AI imagery.” Sample images included in the blog post revealed advancements when using the same prompts in Stable Diffusion XL beta and SDXL 0.9. The images generated with the newer model — including aliens, a wolf and a person holding a coffee cup — appear to show finer detail and more convincing hands. Hands were an easy “tell” to spot AI-generated art — at least until Midjourney v5, a rival platform that runs on Discord, launched in March.

“Despite its ability to be run on a standard home computer, SDXL 0.9 presents a leap in creative use cases for generative AI imagery,” Stability AI said. “The ability to generate hyper-realistic creations for films, television, music, and instructional videos, as well as offering advancements for design and industrial use, places SDXL at the forefront of real world applications for AI imagery.”

Stability AI writes that the new model’s “significant increase in parameter count (the sum of all the weights and biases in the neural network that the model is trained on)” allows for the improved results. Running SDXL 0.9 locally on a PC will require a minimum of 16GB of RAM and a GeForce RTX 20 (or higher) graphics card with 8GB of VRAM. It supports Windows 11 / 10 and Linux.

Stability AI

According to the deleted blog post, the model will soon be available on Stability AI’s Clipdrop web tool and will be added to the startup’s DreamStudio app. The startup says the open-source version of SDXL 1.0 will arrive in mid-July.

From mattresses to scales, it’s commonplace now for even the most basic products to be app-connected. Electric toothbrushes are one of the more curious entries in the “smart” device space. But, smart or not, toothbrushes serve one purpose: cleaning your teeth. The American Dental Association says both powered and manual brushes will effectively do just that, as long as you brush twice a day, for two minutes each, with a soft-bristled brush and fluoride toothpaste.

People who find it easy to hit those marks can probably save themselves the money, but others might benefit from the encouragement provided by advanced brushes. We wanted to test out some of these fancy electric toothbrushes to see just how useful their smarts are. After testing multiple brushes for a few weeks, I’ve come to the conclusion that they aren’t a necessity for everyone, but they could benefit certain folks — particularly those who respond to the gamification of their daily habits.

What to look for in a smart electric toothbrush

Apps

For our purposes, any brush that communicates with a companion smartphone app is one we consider “smart.” Nearly all such apps track your brushing duration and frequency, and can do so whether you have the app open or not. The apps present historical data in graphs, calendars and other easy-to-digest visualizations. Most apps also let you set goals, access tips on better habits and reorder brush heads directly from the manufacturer.

More advanced devices let you adjust the settings and modes within the app and also guide you through brushing sessions with real-time feedback on where the brush is in your mouth. Other apps grant real-life rewards, such as gift cards, for keeping up consistent habits. Teledentistry is even part of the Quip app’s repertoire.

Most people will probably get the most out of the visualization offered by the tracking and history features. I found it satisfying to see a long string of properly executed morning and night brushing sessions, like I had hit some sort of personal milestone. The apps also make it easy to auto-ship brush heads, which could help ensure you replace them more regularly. The ADA recommends getting new bristles every three or four months and I, for one, am terrible at remembering to do that.

At first, I liked brushing along with the apps that were capable of visualizing my movements, but the novelty wore off after a week or so. Stopping to go find my phone just added another step, and I’d always end up sucked into the new notification abyss before I’d remember, oh yeah, I was going to brush my teeth. While the apps’ simple progress tracking is great, the added goals and awards lost their power to motivate me after a few weeks. Many of us are already setting countless objectives for ourselves; worrying about one more virtual award felt like homework for a class I didn’t have to take.

The timer feature is what ultimately helped me brush better. My impulse is to put down the brush after about 45 seconds, which is nowhere near the ideal time. To use that you don’t even need the app though, as all smart brushes include a timer in the brush itself.

Brush mechanics

Whether they’re round or rectangular, all the brush heads vibrate, producing tens of thousands of movements per minute. All the handles emit haptic shakes and pauses to tell you to move to another section of teeth and when your session is done. Most of these electric toothbrushes have batteries that last a few weeks on a charge, or in the case of the non-rechargeable Quip, a few months on a set of disposable cells.

Advanced brushes, usually ones that cost more than $200, also include internal sensors that can detect the orientation of the brush in your mouth as well as the movement and pressure you apply. The brushes use that info to warn you if you’re pushing too hard, moving too fast or missing certain areas, with feedback in the form of lights, vibrations or in-app communication. Some brushes even have tiny, built-in screens that can give you a lot of the same info as an app, such as mode selection, timer duration and simple session assessments, so you don’t have to keep your phone beside you.

Price

A manual toothbrush from your local CVS will run you $4; smart electric toothbrushes can cost between $50 and $400 — quite the price jump. Even the least expensive smart brush offers app-based data tracking, plus haptic feedback and sonic vibrations from the brush itself. More expensive versions incorporate features like specialized heads, LED screens and internal sensors such as gyroscopes — all of which push up the price.

Best overall: Oral-B iO Series 7

Including manual and electric models, Oral-B makes around 75 different toothbrushes. Their latest and most advanced iO Series includes a whopping seven different models — with another on the way. Most of the iO series came out in 2020, which means the iO Series 9 isn’t a newer iteration of the iO Series 5, it’s just a more tricked out brush. The iO Series 7 has a good combination of app features and brush capabilities, and at $200, it sits in the middle of the smart electric toothbrush price spectrum

While using the iO Series 7, an internal gyroscope and accelerometer detects where the brush is in your mouth. If you use the app to guide a session, a 3D illustration of your teeth gradually turns from blue to white as you clean different areas. I was impressed by how accurately it detected exactly where I was brushing, especially since I can’t stick to one area for too long before moving on to the next. But by the end of two minutes, it had pointed me to areas I’d missed and left me with teeth that felt noticeably cleaner.

The iO Series 7 has five different brushing modes, including Gum Health, Sensitive and Daily Clean. I mostly stuck to that last one, but when my six-year-old wanted to try it, I swapped in a new brush head and used the Sensitive setting, which worked great for him. The fact that it made a kindergartener want to brush his teeth might be worth the price right there.

The app accurately tracked unguided sessions, too, adding the time and duration to my stats whenever I synced the brush with my phone. Even without the app, the built-in LED screen on the handle provides a good amount of info, giving you mode selection and displaying a timer as you brush. Haptic shakes let you know when to switch to another quadrant of your mouth.

A ring of light at the base of the brush head will flash red if you’re pushing too hard and glows green when you’re using the correct amount of pressure. At the end of a session, you’ll get a smiley face on the display if you went the whole two minutes, got good coverage and didn’t push too hard. You’ll get a smiley with stars for eyes if you really nailed it.

Oral-B’s top-end iO Series 9 is nearly identical to the Series 7 but costs $100 more. The pricier version comes with a full color LED screen, two extra modes (Tongue Clean and Super Sensitive) and adds another element to app-guided brushing, showing dots that you gradually erase as you brush. Both devices have hard travel cases, but the one for the Series 9 also acts as a charging case. Those are small luxuries that I don’t think justify the price bump though, especially considering the Series 7 did a great job getting my teeth cleaner than they’ve ever felt outside of a trip to the dentist.

Best budget: Quip Smart Electric Toothbrush

If proper motivation stands between you and better dental health, Quip’s Smart Electric Toothbrush might be all you need. It costs $50 if you opt for the brush head subscription or $55 without it. Either way, that’s significantly cheaper than many other smart toothbrushes. The vibrations aren’t as intense as our top pick, nor are the internal sensors as precise, but the app is loaded with ways to track your teeth cleaning and inspire you to do it more often.

One of those is through gamified awards granted for simple achievements like completing 50 sessions or brushing twice a day, three days in a row. It also awards points for good habits, which can be redeemed for real-world perks like discounts on Quip products and $5 Target or Walmart e-gift cards. With its relatively reasonable price and IRL rewards system, Quip’s smart brush might make a nice option for parents who want to help their kids brush better and more often. It’s also handy that the Quip app allows you to pair more than one brush per account, so you can track the whole family’s dental hygiene — something you can’t do with either Oral-B or Philips.

Quip divides sessions into 30 second segments and gives the handle an extra buzz when it's time to move to the next quadrant. A run lasts for the gold-standard two minutes and the sonic vibrations help clean better than the same strokes with a manual brush. The app gives you feedback on coverage, strokes per minute and average back-and-forth movement, providing tips for improvement with each session tracked. Like with fitness apps, seeing your trends and history can be motivating in itself. Combined with virtual achievements and real-world rewards, the Quip might be enough for some people to reach that two-minute, twice-per-day goal without the high price or flashy features.

Honorable mention: Philips Sonicare 9900

I don’t much care for things marketed as “luxe,” but I have to admit I really enjoyed using the $380 Philips Sonicare 9900. Don’t get me wrong, that’s an insane price to pay for a toothbrush. Before I started working on this guide, my daily driver was a $2.29 job I got from Trader Joe’s — and I’d like to add that I’ve only had one adult cavity (which I blame on the charcoal toothpaste fad).

With its sleek design and “premium materials,” the 9900 made me feel like some overly monied influencer doing a #GRWM (get ready with me) routine. The faux leather and gold travel case looks like a cross between a jewelry gift box and an expensive clutch — complete with a cute little strap. The brush itself has a pearlized finish and a decidedly smooth feel.

The app has a clean layout with a detailed history of your past brushing sessions. If you really want to see how consistently you apply the correct amount of pressure, you can. The app is also fairly accurate in identifying areas of your mouth that you skipped or didn’t focus on enough. As for the actual brushing experience, I love the brush head. The bristles are soft and the thin neck is super comfortable to close your mouth around, which helps prevent spillage. I also enjoyed the brush mechanics. Instead of scrubbing back and forth like some commoner, you simply guide the bristles around the surfaces of your teeth, letting the vibrations do the work for you. It took a little getting used to, with the app cautioning me: “don’t scrub!” but once I had it down, it offered the autonomous functionality you’d expect from such an expensive device.

The first few times using the 9900, however, nearly broke the fairytale spell. The vibrations are intense. I didn’t realize you were supposed to put the brush in your mouth before you turned it on, and the shaking flung my toothpaste clean off even when I shoved it down into the bristles. Once I finally got it right, I brushed for the full two minutes and afterwards felt like I had just gone to the dentist — not because my mouth felt clean (though it did), but because my lips were numb like I’d been given Novocain. After setting the brush to the lowest vibration setting, I was able to appreciate it fully without losing sensation in my lips. Maybe I should have expected that much power in a nearly $400 toothbrush, but it took me by surprise.

DuckDuckGo, the privacy-focused alternative to Google, has been working on its own browser. First available on the Mac in open beta late last year, the DuckDuckGo browser is rolling out in beta for Windows starting today. DuckDuckGo says this is “our most requested product for years.”

Naturally, DuckDuckGo is the default search engine here. But the browser has some additional features such as the Duck Player, which will prevent YouTube from serving targeted ads and prevent user-tracked recommendations. YouTube will still see this as a new view, but the browser will prevent any sort of tracking or information that would contribute to your advertising profile.

DuckDuckGo also claims a superior ad-blocking experience. It says that in addition to blocking ads and cookies, the browser will also clean up the white space that’s typically still there with traditional ad blockers. Users familiar with the Mac beta will be familiar with other features including password management, automatic cookie pop-up handling and email protection.

DuckDuckGo first previewed its desktop web browser in late 2021 and released an initial Mac beta in late 2022. Windows is the latest platform to get an official app. But if you don’t use Mac or Windows, DuckDuckGo is available in search engine support on Google Chrome, Safari, Edge, and Firefox. It’s also available as an app for iOS and Android.

EVE Online has finally embraced its destiny. The game, often jokingly called a “spreadsheet simulator” due to the competitive advantages its most dedicated players can gain by tracking in-game data, now has a Microsoft Excel add-in. “Gain a competitive edge by harnessing the power of data, as access to and the understanding of data can spell the difference between victory and defeat,” developer CCP Games wrote Tuesday in a blog post. The free extension, first announced last year at EVE Fanfest, is available now.

Besides serving as crossover marketing for CCP Games and Microsoft, the add-in could help level the playing field and make it easier for new players to enjoy the long-running MMO. “You can now quickly and efficiently arm yourself with the information and knowledge to reach your goals and aspirations,” the development team said. “Easy access to in-game data facilitates decision making and brings added fairness and accessibility to everyone, without requiring coding knowledge or dependence on player-developed third-party tools.” CCP Games collaborated with Microsoft’s Excel team to create the add-in.

Available data includes “your assets with location and item value, market orders, item market prices, wallet transactions, skills, as well as an overview of corporation finances (if you have required roles) to make informed decisions.” After importing your in-game information, you can generate custom reports or visualization tools like graphs and charts. The developer describes it as the “first and only” video game to offer official Excel-based data integration.

“CCP Games has extensive experience in the MMO space, so it’s only natural that we collaborate with them to launch the first-ever native Microsoft Excel add-in for a video game,” said Catherine Pidgeon, Microsoft’s Head of Product, Excel. “With the add-in, the EVE Online player base can seamlessly export and manage data without third-party tools. Through this collaboration, we’re excited to see how players of EVE Online of all skill levels can use Excel to streamline data management and take their in-game experience to new heights.”

To try out the tool, select the “Insert” tab in Excel (desktop or web) and then the “Get Add-ins” button, and look for EVE Online. Alternatively, you can find the add-in in the Microsoft Store. Finally, CCP Games launched a sample workbook to help you get started.

Spotify has really let its desktop app go in recent years, throwing most of its resources at the mobile apps and certain vaccine-hating podcasters. However, the desktop side of things just received a major overhaul in what the company is calling “one of the biggest revamps yet” to bring the standalone app and web app up to speed with more popular smartphone-based cousins. After all, Spotify was originally a browser-based experience even before it made its way to fancy phones.

The main content area remains unchanged, with the same access to browsing and recommended songs and podcasts, but the left-side of the app window now features the recently-launched “Your Library” feature, which the company started testing a few months back. This gives you immediate access to saved music and podcast collections, helping to save time when switching between playlists. You can now collapse the library for a compact view, which is always nice. 

There’s also a new “Now Playing” view on the right side of the screen that displays the current content you are listening to, complete with biographical information on the artist. Additionally, this field gives you access to purchase merchandise directly from the artist and take a peak at any upcoming tour dates. Some podcasts will also automatically populate a transcript via this field as you listen.

The “Friend Activity” feed moved to make room for the new stuff, but you can move it back. Just look for the “friends” icon next to your profile picture at the top-right corner of the main content area and drag and drop to bring the feed back to its former glory. You can also completely remove both the "Friends Activity" and "Now Playing" windows for a streamlined look. 

All of these changes come with an eye-catching splash of paint to make everything look and feel like the smartphone versions of the app. The update rolls out today to all desktop users worldwide. This is a big day for the streaming service, as it just announced that comedian Trevor Noah signed a deal for a weekly talk show and rumors continue to swirl regarding a forthcoming hi-fi audio tier.

Cruise has finally launched an Android app for ridehailing, giving potential customers in San Francisco the option to call one of its robotaxis even if they're not iPhone users. The self-driving car company told Engadget that 20 percent of its waitlisters are on Android, and an app for the platform is one of people's most-requested updates on social media. Cruise's new Android app will come with all the upgrades the iOS app has received since it launched, including the ability to drop a moveable pin on the map by long pressing on the screen. 

Cruise

The company recently started operating in all areas of San Francisco 24 hours a day, seven days a week. Employees have been able to hail robotaxi rides from across the city at all hours for months, but Cruise opened daytime rides to public "power users" in specific portions of the city back in April. To note, when Cruise secured the first ever driverless deployment permit issued by the California Public Utilities Commission last year, it was only given permission to operate in select areas of San Francisco from 10PM to 6AM. 

Passengers with Android phones who become power users, or customers who sign up to test beta features and to send feedback to Cruise for free rides, will be able to hail daytime rides. A spokesperson also told us that Cruise is continuing to expand the availability of daytime rides in San Francisco, so even paying customers will eventually be able to use the service. When the company announced its 24/7 operations, Kyle Vogt, its CEO, said that we'll soon see Cruise "open up full operations in other cities." He said "operating robotaxis in SF has become a litmus test for business viability," and that if the technology can work there, "there's little doubt it can work just about everywhere."

You no longer have to hop between apps just to perform some common tasks in Chrome on your iPhone. Google is updating Chrome for iOS with the option to see Maps addresses, create Calendar events and translate specific text without switching to the relevant app. You can find the location of a restaurant, remind yourself to visit that restaurant and decipher the menu all from one place.

A future upgrade will also make Google Lens considerably more useful. You'll have the option of searching with your camera, whether to take new pictures or draw from your camera roll. As on Android, this might be helpful if you spot a flower or must-have jacket and want to identify it on the spot. The functionality will be available in the "coming months."

You'll still need to use Google's dedicated apps for more advanced functions, such as driving directions in Maps or managing the rest of your itinerary. However, the additions should make Chrome more of a do-it-all app that saves time (and battery life) versus running multiple apps at once. That, in turn, may make Chrome more alluring than Safari as your iPhone's default browser.

The expansion comes soon after Google introduced Chrome Actions, or text-based shortcuts for popular browser tasks like clearing your browsing data and checking settings. Google has even been experimenting with using its own web engine in Chrome for iOS if and when Apple loosens its app policies. Simply put, the company is making Chrome more of a power user's tool.

Vimeo is one of the latest companies to launch AI-powered tools of its own, and as you'd expect, they're geared towards making it easier for creators to edit their videos. The video hosting platform says most people "lack the skills, time, or resources to effectively create and edit videos," and these features are meant to eliminate those barriers. 

Perhaps the most useful of the three new AI tools is the text-based video editor that can automatically delete long pauses and parts of the video with filler words, such as "um" and "ah," with just a single click. Users will also be able to easily remove any part of the video they want by searching for certain words in the transcript that the tool generates and then clicking delete. If they want to create short clips for social media, they can search the transcript for a specific word, highlight and right-click on the word, sentence or paragraph, and then select "keep only this."

Vimeo has also launched a script generator that can conjure a full script based on a text prompt written by the user, the intended video length and the "tone" (such as confident, funny or casual) they choose. According to TechCrunch, it's powered by OpenAI's GPT technology, made into a part of the editing suite through its API. Finally, the company has introduced an on-screen teleprompter that can display scripts with the font size and the pacing the user sets. It could help creators stay on script while maintaining eye contact with the camera.

All three tools will be available in July as part of Vimeo's Standard and Pro subscription plans. While users can test them as part of those plans' seven-day trial period, they ultimately have to pay at least $20 a month (when billed annually) to be able to keep using them. 

Vimeo

With a new update, WhatsApp wants to make spam calls less annoying and let users select the optimal privacy settings, the company announced. The first feature, called Silence Unknown Callers, does exactly that — the calls won't ring on your phone, but will appear in your call list, in case the call is important but you have to respond. For most users, that should offer a decent blend of practicality and privacy. 

And speaking of privacy, WhatsApp also introduced a feature called Privacy Checkup. "Selecting ‘Start checkup’ in your Privacy settings will navigate you through multiple privacy layers that strengthen security of your messages, calls, and personal information," the company said. Doing so provides options like "Choose who can contact you," "Control your personal info," "Add more privacy to your chats" and "Add more protection to your account." 

WhatsApp

WhatsApp also released an emotional new video encouraging users to check in on friends they may be concerned about. The company even provides a template: "Hey, I've been thinking about you. I'm here if you need to chat. No one else can see this but us. And you can also turn on disappearing mode or use the chat lock feature." It's a way for WhatsApp to promote key privacy features — chat lock was just introduced last month, for example. It could also be counterprogramming to the notion that chat lock is tailor made for cheaters, as many commenters pointed out when it launched. The new features are now rolling out.

Uber will soon start displaying video ads in its apps. They’ll appear while you wait for a ride to show up and while you’re in transit, after you place orders in Uber Eats and in search results and other parts of Drizly, the company told The Wall Street Journal. Ads will also be shown on tablets that are placed inside some Uber cars.

Users in the US will start seeing video ads this week. Tablets displaying ads will be installed on a city-by-city basis in the country. The company plans to roll out video ads in the UK, France, Australia and other markets later this year.

Static ads have been shown in Uber Eats since 2019 and in the company’s eponymous ride-hailing app since last year. The company started offering new ad tools in Drizly, the alcohol-ordering app it bought in 2021, last year. Mark Grether, vice president and general manager of Uber’s advertising division, said the company is on course to clear $1 billion in ad revenue in 2024.

The video ads in the apps will be muted by default (audio will play on tablets that are in cars) and will run for up to 90 seconds. An Uber ride lasts around 15 minutes on average, and users typically spend between two and three minutes looking at the app during trips. “We have two minutes of your attention. We know where you are, we know where you are going to, we know what you have eaten,” Grether told the Journal. “We can use all of that to then basically target a video ad towards you.”

The company says it won't share individuals' data with advertisers. You’ll be able to opt out of ad targeting based on demographic data and your activity in Uber's apps, but you can’t opt out of ads altogether, Uber says. Unless, of course, you lock your phone or switch to another app.

It’s not yet clear whether you’ll be able to immediately close an ad once it starts playing. If not, users may temporarily be unable to access certain features in Uber’s apps, such as the safety tools and the ability to message a driver or Uber Eats courier. Engadget has asked Uber for clarification.
