ChatGPT alternative for Android

An open-source option with multiple models, your own API keys, and local chat storage—not a claim to be universally better.

ChatGPT is the default name for AI chat. A ChatGPT alternative for Android makes sense when you want open-source code, multiple models, bring your own API key pricing, or no login to the client app.

Who should consider EchoFlow

Android users who want a ChatGPT alternative with multiple models, ChatGPT alternative with API key control, or a ChatGPT alternative without login to the chat client itself.

Who should stay with ChatGPT

If you want the simplest OpenAI-native experience with minimal setup and are happy with OpenAI's subscription and cloud history, the official app may be easier.

Common questions

Is there a private alternative to ChatGPT?
EchoFlow offers local chat storage, no EchoFlow account, and open-source code. Cloud ChatGPT still processes prompts you send to OpenAI—EchoFlow is private in terms of local history and BYOK control, not a magic offline ChatGPT.
Can I use ChatGPT models in EchoFlow?
You can access GPT models through OpenRouter or OpenAI API keys in EchoFlow, alongside Claude, Gemini, and others.
