Turnstone
Turnstone is a Mac app for creating AI Agents that coordinate recurring work, use connected apps, and prepare drafts for review. It helps operators, marketing teams, and engineers run work through AI models they already use.
Who it's for
- Founders or operators who want a Chief of Staff Agent to organize recurring briefs and coordinate work across connected apps.
- Marketing and outreach teams that want Agents to prepare launch copy, invitations, and follow-ups for review.
- Engineers who want an Agent to investigate code issues, edit code, and run tests without pushing changes automatically.
Not the right fit if…
- People who need a Windows or Linux desktop app: the page offers Turnstone for Mac and specifies Apple silicon and Intel Macs.
- Teams that need Agents to keep running while their Mac is closed today: Turnstone Cloud, which is described for that use, is marked as coming soon.
How it fits your workflow
Download Turnstone for Mac, sign in with an AI plan or configure a key, and connect the work apps you want it to read. Choose how often it checks those apps.
Tell the Chief of Staff what you are working on or give a task to a specific Agent. Agents can pass tasks to one another, use their own browser tabs, and retain work context; users can switch models during a conversation.
Review the returned work in Turnstone, such as a brief, code change, or email draft. The page says messages are not sent until the user sends them, and scheduled Mac tasks run when the Mac is on.
Pricing
Free: Turnstone for Mac is free forever and requires no card. The page says its free connectors are included. Turnstone Cloud is described as coming soon, with a first-month-free offer for the first 1,000 people.

Key features
- Team of persistent Agents
- Create Agents for different jobs, such as outreach, launch writing, signups, or engineering. A Chief of Staff Agent can set up Agents for parts of a task, and Agents can hand work to one another.
- Model choice and switching
- Use AI services or models supported by the user's plan or key, and switch models during a conversation while the Agent keeps its job and context.
- Work memory and writing preferences
- Turnstone keeps Agent chats and memory on the Mac, and the page says Agents learn preferences such as writing style from connected work.
- Scheduled tasks
- Users can ask an Agent to run a recurring task, such as a weekday morning brief. On the Mac, the scheduled task runs when the Mac is on.
- Connected-app updates
- Turnstone can read connected apps on a schedule selected by the user and share updates with Agents, including information about what changed or was decided.
- Browser work
- Each Agent uses its own tab in the Turnstone Browser to open sites, read them, and fill in forms while the user watches.
Works with
- AI models and providers
- Gmail
- Slack
- Google Calendar
- Granola
Limitations to know
- The downloadable application described on the page is for Mac, specifically Apple silicon and Intel Macs.
- Scheduled tasks on the Mac run when the Mac is on.
- Turnstone Cloud is marked as coming soon on the page.
Alternatives to consider

CommanderGPT
Choose it if you want a command interface with reusable slash-command workflows across multiple AI models rather than Turnstone's persistent desktop Agents and connected-app work.
