About Turnstone
Turnstone is the AI workspace where your agents already know you. Connect your apps (e.g. email, calendar, Slack, Drive) and your local folders. Turnstone turns all of it into your second brain and continuously updates it.
Spin up agents (e.g. chief of staff, research, GTM) that all share that brain, so you stop re-explaining yourself and start getting real work done.

It all lives on your machine and runs on any model you already pay for. Ask your agent once, and it's done.
