Chai
Mobile chat app with millions of user-made bots
Overview
Chai is one of the longest-running consumer chatbot apps, available on iOS and Android, where users chat with and publish their own AI characters. The catalog is enormous and community-driven, covering romance, anime, horror, comfort characters and interactive stories.
The company trains its own conversational models and tunes them on user feedback, which shows in quick, casual replies that suit short sessions on a phone. It is less of a dedicated girlfriend app and more of a broad social chatbot platform, so depth of memory and visual features lag behind specialist companion services. The app is free to download with message limits, and paid tiers lift those limits.
Our Verdict
A huge, lively bot library that is great for casual mobile roleplay. Look elsewhere if you need strong memory or images.
