Stella - Your AI

Stella is a personal AI assistant for your phone and computer. Ask a question, talk through an idea, or send work to your paired computer while you're away.

Use Stella to:
• Chat with an AI assistant from your phone
• Speak instead of typing with voice input
• Pair with the Stella desktop app and ask your computer to browse, manage files, or run tasks
• Choose Stella models, your own provider keys, Codex, or Claude Code on a paired computer
• Keep chat history and local context on your devices rather than in a cloud message archive

Stella is local-first and open source. Depending on how you use it, message content may be processed by Stella services or the AI provider you select to produce a response. See the privacy policy for details.

Computer control requires the Stella desktop app and a paired computer. What Stella can do depends on your computer, selected model or engine, connected services, and permissions.
