1Your Chief of Staff

Meet Marcus. He runs the team.

Your first Agent runs the team and creates one for each part of the job. Each learns your way and knows when to ask for your call.

2The team

One Agent for every job. Each remembers your way.

Every Agent remembers how you like the work done. Put each one on the AI that’s best at it.

4How it works

How your team works, in three steps.

Your Agents pass work between them and browse the web for you. They also handle the jobs that repeat.

  1. 1

    They pass work along

    Any Agent can hand a task to another, and the result comes back to your chat.

  2. 2

    Each has its own browser

    Every Agent works in its own tab, opening sites, reading them and filling in forms while you watch.

  3. 3

    They keep a Schedule

    Say "every weekday at 9" and your Agent saves a Schedule, runs it and reports back in your chat.

5Memory

They already know you. So you stop explaining.

Turnstone reads your work and keeps every Agent caught up. Each learns how you write and drafts in your voice.

Keeps up with your work

Turnstone reads the apps you connect, on a schedule you pick, and tells every Agent who said what, what changed and what was decided.

Writes like you

It learns how you write in each app and account, from Gmail to WhatsApp, and drafts in your voice. Nothing goes out until you send it.

6Price

How Turnstone compares

Common questions

Where does my data actually live?

Your Agents, chats and memory live on your Mac in a folder you can open. Cloud keeps them working while your Mac is closed, same folder. No model is trained on what you connect.

Do you train on anything I connect?

Turnstone doesn’t train on anything you connect. What you connect is read only to build your own Agent memory. Nothing is trained on it by anyone.

Which models can I use?

Sign in with ChatGPT, Claude, Grok or Cursor on your plan. Use an API key for Gemini and more. Want the AI on your Mac? Run a model with Ollama.

So do I need to pay for AI separately?

You sign in with the plan you already pay for. Cloud is $49 a month after the free month. Your Mac is free forever.

What does it read, and can I stop it reading something?

Turnstone reads the apps you connect on a schedule you set. You pick which apps, which folders, and when. Turn any of it off anytime.

What if I delete Turnstone?

Your memory folder stays on your Mac. Reinstall Turnstone and it reads that folder. Your Agents come back and remember everything.

What does it cost?

Turnstone for Mac is free forever. Cloud is $49 a month after the first month free. The first 1,000 people get one free month. Mac works alone.
