Data sovereignty

No accounts. No middleman. Local by default.

Conversations, summaries, embeddings and search indexes live in one local SQLite database on your device. Out of the box, a local model does the summarizing — nothing leaves your machine.

Prefer GPT, Claude or Gemini for sharper summaries? Bring your own key — it talks straight to the provider, never through a ContextVolt server. Your embeddings and search index stay local either way.

No account or API key required to start
No telemetry, ever — nothing phones home
