Your key, your call
The agent runs in the cloud, without needing your phone to run — it works on a model key you already own. No new subscription, no monthly model bill, no usage caps. When a model company prices you out, the agent stays yours.
A personal AI agent
Bartimaeus
Close your laptop, go for a walk and the agent still gets your work done.
The short version
Works with your keys, in your apps, on your phone — and asks before it acts.
Reads first. Asks before it acts.
Everything starts read-only. Drafts wait in your outbox until you tap send. Anything sensitive pauses and comes to your phone as an approval card — approve, deny, or undo.
Runs on your routine
Set a skill on a schedule — a morning brief before coffee, a Friday tidy of your inbox. It works while you are away from the phone and leaves you a receipt of everything it did.
Three steps
Three steps to your own agent.
-
Bring your key
Use the model key you already pay for. Two minutes, no new accounts, no credit card.
-
Connect your apps
Gmail, Calendar, Todoist, Notion and more. Every connection starts read-only and keeps its own kill switch.
-
Approve as it works
Drafts, schedules and lists land on your phone. One tap approves. Every action can be undone.
