Configuration
Choose your AI provider and connect the integrations you want.
All configuration lives in the Settings app inside MeghaOS — there are no files to edit. Changes to the AI provider take effect immediately, without restarting.
AI provider
MeghaOS works with any major AI provider. In Settings → AI, pick a provider, paste a key (if the provider needs one), and choose a model:
| Setting | What it is |
|---|---|
| Provider | Which AI service to use (hosted or local) |
| API key | Your key for the chosen provider (not required for local models) |
| Model | The specific model to run |
MeghaOS ships 25+ built-in providers — OpenRouter, OpenAI, Anthropic, Google Gemini, Groq, xAI/Grok, DeepSeek, Mistral, Together, Cerebras, NVIDIA, Perplexity, Cohere, and more — plus local runners (Ollama, LM Studio, vLLM) that need no key. Because most providers use the OpenAI-compatible format, you can also point MeghaOS at any compatible endpoint via the Custom OpenAI-compatible API option. See AI Providers for the full list.
The AI settings are live — switch provider or model in Settings and the next request uses it, no restart required.
Integrations
Every integration is optional. Add credentials in Settings → Integrations only for the capabilities you want to use.
Some integrations are macOS-only because they use native Apple apps — iMessage, FaceTime, Apple Mail, Notes, Reminders, Contacts, and more. These work in the macOS edition without extra credentials. See Editions & Platforms.
Privacy & data
MeghaOS is a closed, self-contained system. Your data — chats, calendar, saved widget state, memory, and credentials — is stored locally on your device. Requests go only to the AI provider you configure (or stay entirely on-device with a local model).
Limits & behavior
A few system behaviors are tuned out of the box and don't require configuration — things like how long a workflow step may run and how many steps run in parallel. These sensible defaults keep the assistant responsive.
