Features

Built for provider freedom

Use the best model for each task. Switch providers without switching apps. Keep full control over your API keys and data.

Bring your own keys

Connect your API keys directly. No middleman subscription, no vendor lock-in. You pay providers at cost and switch any time.

Desktop-native

A real app on your machine — not a browser tab. Fast, private, always available.

Private by default

Chats, keys, and files stay on your machine. Nothing is stored on our servers. Ever.

Attach anything

Drop files and images into your chats. Get analysis, summaries, and answers grounded in your content.

Multi-provider

One app, every model

GPT-5.2, Claude Opus 4.6, Gemini 3.1 Pro, Grok 4 — and many more to come — all accessible from a single model selector. Tune reasoning effort per task. Compare outputs across providers.

  • Switch models without switching apps
  • Adjust reasoning effort per message
  • New models added regularly
