Most AI apps lock you into one provider. EchoFlow is a multi-model AI app for Android that lets you chat with different AI models, compare approaches, and switch between AI models mid-conversation from a single tap.
One app, every model you need
Add models through OpenRouter or direct provider APIs. Frontier models, fast models, reasoning models, and free options can all live in one list. The benefit is practical: draft with a fast model, refine with a stronger one, or compare answers without juggling subscriptions and separate apps.
Switch models without losing the thread
EchoFlow is an AI chat app with model selector built into the chat header. Change models during a conversation when a task needs different strengths—coding, research, creative writing, or quick Q&A.
Universal AI chat for power users
- Model directory — search, favourite, and organise your models
- Custom model IDs — add any model your provider supports
- Reasoning traces — see how supported models think before they answer
- Same toolkit everywhere — web search, documents, and Deep Research work across models
Not just a model list. EchoFlow is a full Android AI assistant—open-source, privacy-focused, and designed so you control which models you use and what you pay.
