Cinna vs Polyflow Agents

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. Why Cinna • Chat with any top AI model using your own keys • Orchestrated multi-agent, multi-tool conversations • One-tap jobs: complex tool-and-agent workflows, automated • A2A agents and MCP tools, including your own custom builds • Notes built in to enrich every conversation • No app subscription — pay only your provider • Privacy-first: keys and data stay yours

Polyflow Agents is a phone client for an AI agent that runs on a computer you own. If you run Hermes — the open-source agent host — this puts that agent in your pocket: the same sessions, the same tools, the same memory, reachable from wherever you are. There is no account to create and no server of ours in the middle. The app connects straight to your host, over your own network or a private tailnet, and sends everything you do to it and nowhere else. TALK TO YOUR AGENT Type a message, dictate one, or send a photo. Replies stream in as the agent writes them, with each tool it uses shown as it runs. Sessions are persistent: pick one up from the list, search across them, rename, pin, or delete. APPROVE THE RISKY BITS When the agent needs permission — to run a command, say — it stops and asks. With the host plugin installed you get a push notification, and Allow or Deny is one tap from the lock screen. Deny sends it back to think again; nothing runs until you say so. EVERYTHING IT MAKES, KEPT Reports, pages, images, and files the agent produces land in Artifacts, ready to open on the phone. Versions are kept when a file is rewritten, so you can see what changed. SEE WHAT IT IS DOING Scheduled jobs, with their last result and next run. Tools and integrations. The model and provider it is set up to use. Logs and events, when you want to know why. SEVERAL AGENTS, ONE AT A TIME A host can run more than one agent. Add a server once and the app asks what it hosts; switch between agents and the whole app re-scopes to the one you picked. WHAT YOU NEED A Hermes host you can reach from your phone — on the same network, or through a tailnet such as Tailscale. Push notifications need a small plugin on the host; the app walks you through installing it, or can send the instructions to the agent to do itself. No host yet? Tap "Try the demo agent" on the first screen. It answers with a scripted conversation, asks for a permission, and produces an artifact, so you can see every screen before you set anything up. WHAT WE DO NOT DO We do not run analytics. We do not collect crash reports. We do not see your conversations, your files, or your credentials — they go to your host and stay there. Your sign-in is kept in the phone's keychain and sent only to the host you gave it to. Polyflow Agents is open source, MIT licensed.
