About BayesChat

BayesChat is an AI chat app for iPhone and iPad that connects to any model through OpenAI- or Anthropic-compatible APIs, including local models, using your own API key stored in the iOS Keychain. Beyond chat it offers MCP servers for tool calling, on-device memory you can review and edit, reusable chat presets (model, prompt, parameters, tools and memory in one tap) and background tasks that keep running after you leave the app. The free tier allows one provider and 50 messages a month; a one-time $14.99 Pro unlock removes the limits.
