Microsoft is launching Copilot Health, an AI health assistant that pulls data from wearables, medical records, and lab results to deliver personalized health advice. Long term, the company says it’s working toward “medical superintelligence.”
ChatGPT still dominates the chatbot market, but its lead is shrinking. New data from Similarweb shows OpenAI's chatbot accounted for just 61.7 percent of global AI web traffic in February 2026, down from 75.7 percent twelve months earlier. The biggest winner is Google Gemini, which more than quadrupled its share from 5.7 percent to 24.4 percent over the same period. Grok (3.4 percent) and Claude (3.3 percent) have overtaken DeepSeek (3.2 percent) for the first time, claiming third and fourth place. Claude crossed the three percent mark for the first time in February, though it's much stronger in the B2B market, according to a separate study.
In absolute numbers, ChatGPT recorded 5.35 billion visits in February, while Gemini pulled in 2.11 billion. Grok came in at 298.5 million visits, Claude at 290.3 million, Deepseek at 246.4 million, and Perplexity at 153.8 million. Microsoft's Copilot stagnated at 1.1 percent market share, though that only reflects the web version. Microsoft's actual share of the enterprise market is likely much higher.
Google has introduced "Ask Maps," a conversational feature powered by its Gemini models. Users can ask questions in plain language, like "Is there a public tennis court with lights on that I can play at tonight?" or "My phone is dying — where can I charge it without having to wait in a long line for coffee?" The feature taps into data from more than 300 million locations and reviews from over 500 million contributors.
Results show up on a personalized map based on past searches and saved places. Users can book tables, save or share locations, and jump into navigation directly. Ask Maps is rolling out first in the US and India on Android and iOS, with a desktop version on the way.
Google also announced "Immersive Navigation," a revamped turn-by-turn system with a 3D view of surroundings, including buildings, overpasses, and lane markings. Gemini models generate the visuals by analyzing Street View and aerial imagery.
Immersive Navigation launches first in the US, expanding to more iOS and Android devices, CarPlay, Android Auto, and cars with built-in Google over the coming months.
OpenAI is reportedly planning to fold its video AI Sora directly into ChatGPT. So far, Sora has only been available as a standalone mobile and web app. OpenAI originally pitched it as a viral hit and potential TikTok alternative, a strategy that seemed to work early on, partly thanks to massive copyright infringements.
That momentum didn't last. According to The Information, the app has slid from No. 1 to No. 165 in the Apple App Store since launching last fall. CEO Sam Altman reportedly admitted internally that hardly anyone was sharing videos publicly. Rolling Sora into ChatGPT might fix that: with around 920 million weekly active users, the move would naturally drive more video generation. The standalone app will stick around for now, The Information reports.
Google already offers video generation in Gemini, though with tight capacity limits and only for paying subscribers. OpenAI will likely go a similar route: the company is strapped for compute, burns through cash supporting the roughly 95 percent of free ChatGPT accounts, and video generation is especially resource-hungry.
A federal court in San Francisco has granted Amazon an injunction against AI startup Perplexity, barring it from using its AI browser agent Comet to make purchases on Amazon.
Amazon sued Perplexity in November, accusing the startup of fraud because Comet didn't disclose when it was shopping on behalf of a real person and ignored Amazon's demands to stop. The case raises a growing legal question: how should courts handle AI agents taking on complex tasks like online shopping?
Judge Maxine Chesney ruled that Amazon presented strong evidence that Perplexity was accessing users' password-protected accounts with their permission but without Amazon's authorization. Perplexity must also delete any collected Amazon data and has one week to appeal.
There's an interesting wrinkle here: Amazon recently became a major investor in OpenAI, which also sees product research and online shopping as key AI chat features. So far, though, OpenAI reportedly hasn't cracked direct checkout in its chat interface. Amazon may be positioning itself to step in and own that piece of the puzzle.
OpenAI is rolling out dynamic visual explanations for more than 70 math and science concepts in ChatGPT. Users can tweak variables in real time and see the effects on graphs and formulas instantly. For now, the topics are geared mainly toward high school and college students, covering things like binomial squares, exponential decay, Ohm's law, compound interest, and trigonometric identities.
According to OpenAI, the interactive explanations are available now to all logged-in users worldwide, regardless of their subscription plan. Over time, OpenAI plans to expand the learning modules to cover additional subjects.
A German regional court has ruled that song lyrics written by a human are still protected by copyright, even if the music was made with AI tools like SunoAI. Simply claiming a work is AI-generated isn’t enough to strip that protection, you need proof.
