today we're launching AI Passport (@ycombinator S26) - web 4.0 is private, hyper-personalized, and runs on us. The main blocker to ubiquitous consumer AI is that every major AI assistant and consumer app is building its own private and incomplete model of the same person. ChatGPT holds one model, Claude another, while the data in health apps, calendar, shopping history, travel accounts, wearables, and financial tools remain trapped in separate silos. No product has the complete context needed to understand you, and no user has a single place from which to control it. AI Passport acts like Link for personal context. Users build a single, portable profile by connecting the apps and assistants they already use. That same Passport then becomes a plug-and-play connector for consumer apps through their 'Sign in with AI Passport' OAuth, which provides scoped and time-limited access to context. try it out: build by @erinmerylstudy and @davidobot_
