New AI Assistant Wabi Builds Custom Apps for You and Your Friends

Wabi is a new AI assistant that launches today, created by Eugenia Kuyda, who also founded the AI companion app Replika. Unlike other assistants that keep everything in one long chat, Wabi uses separate threads for different parts of your life—like health, family, or hobbies. Within each thread, the AI can build custom mini-apps for you, such as a weight-loss tracker or a list of nearby kids' events. The idea is to give you personalized software without you having to build it yourself.

What makes Wabi stand out is that it's multiplayer: you can invite other people into your threads, turning them into group chats with the AI. For example, you and your partner could share a thread with apps for date ideas, a shared calendar, and a reading list. The AI can answer questions about your availability or plans, but only within that shared space, and everyone can see when your personal data is requested. This makes it easier to coordinate and connect with others.

Kuyda believes single-thread AI assistants get worse over time because they get overwhelmed with too much context, leading to mistakes. By breaking things into threads, Wabi stays more organized and useful. The app is free to use, and the company says it takes privacy seriously, with independent audits of its data security. Most data is stored in the U.S., and you control what you share in each thread.

Wabi is part of a growing wave of personal AI assistants that promise to simplify your life. But Kuyda's vision is more social—she wants to bring people together through shared AI experiences, not just have you interact with an AI alone. As she puts it, 'I don't think anyone has yet cracked multiplayer.' Wabi is her attempt to do just that.
