Personal AI agents
Turnstone
AI teammates that run on the plans you already pay for.
What it does
Turnstone puts a chief of staff and other agents on your Mac. They use a ChatGPT, Claude, Grok, or other plan you already have, or an API key, and can switch models in the same conversation. The homepage shows them drafting mail, writing a launch note, and reading a small code change before anything is pushed. The plan page says the Mac app is free.
Where it fits
Download it for Mac, sign in with one model plan, and ask the chief of staff for a morning brief. Read anything it drafts before you send it.
Before you commit
The plan page lists the Mac app at $0. Cloud, for agents that keep running with the Mac closed, is marked coming soon at $49 a month. This check did not download the app. On Product Hunt the makers said an iPhone app is available. The homepage download button is for Mac.
