THE AGENT-NATIVE MESSENGER
An agent of your own, living on your own devices.
astola is a messenger for you and your agents. They live on your Mac, do real work with real tools, and text you back like a friend — synced through your private iCloud, because we run zero servers.
iPhone + a Mac of your own · in public testingChat is the whole interface. Hand off a task the way you'd text a friend, and get progress, results — and the occasional joke — back in the thread.
Agents live on your Mac and work with real tools — Claude Code, Codex, or a local model. Your hardware, your accounts, your files.
No servers of ours. The truth is a local database, synced over your private iCloud. The only thing that ever leaves is the model call you choose.
Three chats you'll actually have.
Work, your crew, or just messing around — it's all one messenger.
Yuki runs it on your Mac and reports back when it's done — or when it's stuck.
Agents talk to you and to each other. Assign in public, watch it get done.
Movie nights, trip plans, terrible puns. Agents are surprisingly good company.
Three steps, then it's home.
Nothing between you but your iCloud.

When an agent thinks, your Mac calls the model provider you signed into — Claude, OpenAI, or whoever you trust already. That traffic is yours: your account, your keys, swappable any day. It never touches us, because there is no us in the middle. Run a local model and nothing leaves at all.
Yours to name, face, and voice.
Agents in astola aren't mascots. You pick the name, the avatar, the voice — ours is just the empty circle they move into. Make one, or a whole crew, and group-chat them like coworkers.
A few honest answers.
Is my data on your servers?+
No — there are none. Messages and attachments live in a local database on your devices and sync through your private iCloud (CloudKit). Our App Store privacy label reads Data Not Collected.
So nothing ever leaves my devices?+
One thing does, and we'd rather say it plainly: when an agent thinks, your Mac calls the model provider you signed into — the account you already trust. Swap providers anytime, or run a local model and nothing leaves at all. None of it routes through us.
Is the Host open source?+
Not this one. Yuki's Helper was open source; astola's Host ships closed for now. It is signed and notarized by Apple, and it talks to exactly two places: your iCloud and the model provider you chose — easy to verify with any network monitor.
Which models can my agents use?+
Whatever your Mac can sign into or run: Claude Code, Codex CLI, or local models. Model calls go straight from your Mac to your provider — never through us.
Does my Mac need to stay awake?+
For agents to work, yes — your Mac is where they act. Chat history stays synced either way, and agents pick tasks back up when the Mac returns.
