🎾 Tennis pros reveal how they're using ChatGPT to scout rivals

🏋️ Echelon launches an AI workout builder for gyms and home users

Golf welcomed its first AI commentator to a professional broadcast. An AI personality named Duff Foreman will join human hosts in the booth at the New Mexico Open, marking what organizers believe is the first time an AI has interacted live with hosts at a professional golf tournament.

Meta and Arccos are turning smart glasses into a hands-free golf caddie. Arccos has partnered with Meta to bring its AI golf platform to Meta AI Glasses, letting golfers ask for yardages, club suggestions, and course strategy through voice commands instead of pulling out a phone. The company says its average user lowers their handicap by roughly 25 percent in their first season.

A golf AI agent startup just closed a multi-million dollar funding round. PathFinder, maker of the vision-powered golf coaching device BirdieSense, secured a multi-million dollar angel round to scale manufacturing ahead of a global crowdfunding launch. The device tracks ball flight and swing mechanics using cameras rather than radar, and the company plans to expand into tennis and baseball next.

Echelon launched an AI app that builds personalized workout plans for gyms and home users. Echelon Workout Builder AI creates adaptive seven-day strength and recovery programs based on a user's goals, equipment, and recovery, then adjusts future sessions based on performance. The company also offers a white-label version for gyms that integrates with systems like Mindbody and Club Automation.

RunSignup launched an AI-powered Contact Us form that answers race participants' questions before they reach a director's inbox. The tool, RunSignup's first product built on its new AI infrastructure, draws on both a race's website content and live database fields like start times, price increases, and refund policies to answer instantly, routing participants to human support when it can't help. It activates automatically for races already using RunSignup's AI Chatbot.

ESPN and Disney+ are testing AI search tools to help fans find what they want faster. ESPN Search, now in beta, lets fans ask sports questions in natural language and pulls answers from decades of ESPN's articles, stats, and video. Disney+ is running a similar experiment that recommends shows based on a viewer's mood rather than just their watch history.

Tennis players are quietly using ChatGPT to scout their opponents. Several WTA and ATP players say they, or people around them, use ChatGPT to research unfamiliar opponents' playing styles before matches, though reactions on tour are mixed. The ATP has also built its own AI platform, Tennis IQ, to analyze in-match performance data.

Google's Pixel Watch can now flag insulin resistance and blood pressure trends from your wrist. Google's new Health Guardian platform uses an AI model to analyze heart rhythm, sleep, and activity data, giving wearers a monthly score for insulin resistance and blood pressure trends. The features roll out this fall to the Pixel Watch 3, 4, and 5, and the Fitbit Air.

Apple may be building a screen-free fitness tracker to take on Whoop and Oura. Bloomberg reports Apple's design team is considering wearables without displays, alongside premium and budget Apple Watch models, as it looks to compete more directly with Whoop and the growing recovery-tracker category. Apple Watch sales still jumped 21 percent in the first quarter of 2026 even as new entrants like the Fitbit Air and Garmin Cirqa gain ground.

Apple is reportedly exploring smart glasses as a health and fitness platform. The company has looked at features like audio coaching and camera-based form correction for future glasses, following an earlier abandoned effort to bring workout tracking to the Vision Pro. Apple is also hiring for roles focused specifically on health and fitness within its wearables team.

Wall Street is pouring money back into fitness, this time chasing AI coaching apps instead of hardware. Investors who fled after Peloton's collapse are now funding AI personal training apps like Fitbod, Freeletics, and HealthifyMe, drawn to a market projected to grow from roughly $9.8 billion to $46 billion by 2034. Analysts expect the winning model to be hybrid, with AI handling standardized programming while human trainers focus on accountability and complex cases.

AI is reshaping how sports helmets get designed. Engineers are combining simulation software, 3D-printed foam lattices, and AI-driven modeling to predict aerodynamic outcomes that used to take days to compute, cutting down on physical crash testing. Designers say the technology gets them about 80 percent of the way there, with the final engineering judgment still belonging to humans.

Nobody became a developer to write documentation. But the docs still need to get written — PRDs, README updates, architecture decisions, onboarding guides.

AI often fills in missing details with assumptions. That can produce an answer that looks useful but doesn’t actually fit your situation. This prompt instructs the AI to pause and ask questions whenever missing information could materially affect its response.

Add it to the end of any request involving planning, recommendations, strategy or decision-making:

For example, if you ask AI to create a marketing plan for a new product, it might first ask about your target customer, budget, goals, timeline, sales channels and existing audience. Once you answer, it can create a plan tailored to your actual situation instead of generating a generic strategy based on assumptions.

This prompt works especially well for business plans, marketing strategies, project planning, presentations, hiring decisions and other tasks where context can significantly affect the answer.

OpenAI's chief revenue officer, Denise Dresser, is leaving the company, the second senior executive exit in a matter of days as OpenAI prepares for a potential IPO.

Anthropic will begin watermarking AI-generated content from Claude to comply with new EU transparency rules, with the change rolling out worldwide rather than just in Europe.

SpaceXAI launched Grok Bot, a persistent AI agent that can sign into your apps and websites and keep working on tasks even after you close your laptop, starting at $120 a month.

OpenAI made GPT-5.6 Luna the default model for free ChatGPT users, giving them unlimited text chats with no rate limits for the first time. It has also cut prices on its newest GPT-5.6 Terra and Luna models, trimming Terra by 20% and Luna by 80% just three weeks after launch as competition from cheaper Chinese open-weight models heats up.

Google's Gemini is losing market share to ChatGPT and Claude, according to three separate sets of usage data, with one tracker calling the drop a "collapse." Google has also lost several of its top AI researchers, including longtime chief scientist Jeff Dean, who is departing to start a new company alongside other DeepMind veterans.

Anthropic brought Claude Cowork to the Chrome side panel, so a task started in a browser tab can now be picked up later on desktop, web, or mobile.
