Maybe you could try AirJelly, a context-aware proactive AI companion we are building recently. Data are all stored locally, on your MAC. Local LLM models would be difficult, as we also use Claude/Gemini to serve as the model provider. But as the software builder, we don't collect any user information, anything for improving our product would be sent by our users voluntarily (just send feedback in the app). If you would like to try, you could visit our website airjelly.ai.
