From the Causal ecosystem
Meet Orion
A privacy-first AI desktop research assistant. Bring your own API keys, keep your data local, and work with any AI model — all from one native app.
Bring Your Own Key
Use OpenAI, Anthropic, Google, or any custom provider. Your API key stays on your device — never sent to our servers.
Fully Private
All conversations and files are stored locally. No telemetry, no analytics, no cloud sync.
Native Desktop App
Available for Windows, macOS, and Linux. Built with Electron for a fast, native experience.
Project Memory
Pin notes and context that persist across every session. Orion remembers what matters for your work.
File Attachments
Attach PDFs, code files, images, and more. Orion reads and reasons over your documents.
Multi-Provider
Switch between models without re-entering keys. OpenAI, Gemini, Claude — all in one place.
No subscription. No per-query fees.
Orion is free to download. You pay only for the AI usage through your own provider account — directly, at their rates. Causal never touches your API costs.
