ChatOn

ChatOn is a general purpose AI assistant app from AIBY Inc., a Miami based developer, available on iOS, Android and the web at chat.chaton.ai. It combines several third party models behind one chat interface so a user can ask questions, draft emails and essays, generate and edit images, turn photos into short videos, summarize PDFs and YouTube videos, solve math problems with worked explanations and search the web for current information. Conversations sync across devices. It is aimed at consumers and busy professionals who want one app rather than separate subscriptions to each model vendor. The App Store listing names current OpenAI, Google, Anthropic and Perplexity models, and the web version lists a lighter OpenAI model for free users. The app ships more than 100 built in prompts for common writing jobs, reads PDF, DOC, TXT and EPUB files, converts images to text for document scanning, and supports 19 or more languages. It requires iOS 16 or later and also runs on Apple Vision. Pricing is by in app purchase and is published only in the App Store, not on the vendor site. A free tier covers basic chat with the lighter model. Premium is listed at $6.99 and $7.99 for weekly options, $29.99 for a month and $39.99 for a year, and a Premium PRO+ annual purchase is listed at $59.99. Amounts and names can shift between regions and app versions, so the store listing is the authority on the day of purchase.
