Omni AI is the closest ChatOn alternative: the same kind of all-in-one mobile assistant, but with 20+ models from every major vendor instead of ChatOn's handful, and a monthly plan at around $9.99 versus ChatOn's roughly $7–8 per week.
ChatOn, by AIBY, is one of the most downloaded AI chat apps on both stores and is polished — writing tools, PDF and YouTube summaries, image generation. Its two recurring complaints are the weekly billing (around $7.99 a week adds up to more than $400 a year) and the limited model choice, which is a curated set of GPT, Gemini and Claude rather than an open catalogue.
If you like ChatOn's format but want more models, real mid-conversation model switching and a lower monthly price, Omni AI is the switch. If you specifically rely on ChatOn's PDF workflow and are happy with its pricing, there is less reason to move.
Why people look for a ChatOn alternative
- Weekly subscription pricing that costs more per year than any monthly AI plan
- Model choice is limited to a curated few — no Grok, DeepSeek, Mistral or Llama
- Switching models means starting a new chat rather than continuing the thread
- Video generation and web search are gated or add-on features

Who should switch from ChatOn to Omni AI
Switch if you pay ChatOn weekly. A weekly plan at around $7.99 is more than $400 a year; Omni AI's yearly plan is $59.99 and includes every model. Switch if you want to compare answers — running the same prompt through GPT-5 and Claude in one thread is the core Omni AI workflow and something ChatOn is not built for. And switch if you want Grok, DeepSeek or Mistral, which ChatOn does not offer.
Stay on ChatOn if its guided writing tools, PDF Q&A and YouTube summaries are the main reason you opened it, and you are on one of its yearly plans. Those are mature features and Omni AI's document tools are more general-purpose.
Moving over takes five minutes
Install Omni AI from the App Store or Google Play, sign in with Google or Apple, and your chats sync across devices from the first message. There is nothing to import from ChatOn — conversations are not portable between AI apps — so the practical step is to cancel the ChatOn renewal in your phone's subscription settings so the weekly charge stops.
