Overview

ChatOn is a mobile AI assistant app developed by AIBY Inc., a Miami, Florida-based consumer app company founded in 2019. AIBY builds and operates a portfolio of mobile-first products with a combined audience in the billions of users, and ranked among the top 10 parent companies by non-game US App Store downloads in 2023 alongside firms like Google and Meta.

Built on GPT-4 and GPT-5-class models, ChatOn combines a general chat assistant with a Doc Master tool that analyzes, summarizes, rewrites, and translates PDF, DOC, TXT, and EPUB files, plus voice-to-text transcription and a text lab for drafting emails, speeches, and social posts. By October 2025 the app had passed 85 million downloads and over 1 billion completed user tasks across 236 countries.

ChatOn suits mobile users who want one app covering chat, document handling, and writing help rather than separate single-purpose apps. The app stays free to download with a premium subscription unlocking full features: weekly access runs about $6.99-$7, with yearly plans around $50-$60 depending on the promotion and platform, iOS or Android.
