Cinna

Cinna — Your AI, Your Agents

Cinna is a privacy-first AI client that puts you in control. Bring your own provider keys and chat with the world's top AI models — no app subscription, no middleman. Your keys stay on your device, in the secure keychain.

Orchestrate many agents and tools in one chat
This is where Cinna goes beyond a simple chatbot. Combine multiple AI agents and tool servers in a single conversation and let a model conduct them for you. Ask once, and Cinna plans the work,
calls each agent and tool as needed, and weaves their results into one coherent answer — every reasoning step and tool call visible, or neatly folded away. Watch delegated agents work in their own
expandable sub-threads, all within the same chat.

Bring your own AI
Connect your own API keys for leading providers and pick the exact model you want. No lock-in, no usage markup — you pay your provider directly, and Cinna never touches your data.

Unlock custom-built agents with a self-hosted Cinna server
Connect your own self-hosted Cinna server to bring your custom A2A agents, MCP tool servers, and published agent bundles into the app. Browse a catalog and install agents in a tap, track their
live status, and keep them up to date — all from your phone.

Turn complex workflows into one-tap jobs
Save an entire orchestrated process as a reusable job and run it with a single tap. A job can chain multiple MCP tools and AI agents into one automated workflow — the same multi-agent
orchestration that powers your chats, captured once and repeatable on demand. Run it locally on your device or hand it off to your Cinna server as a task, and review the full run history every
time. Organize jobs into folders so your most powerful workflows are always one click away.

Built-in notes
Keep markdown notes organized in folders and attach them straight into a chat to give your models and agents exactly the context they need.

Private by design
Your provider keys live in your device keychain. Your chats, notes, and jobs are stored on-device — your data stays yours.
