A local-first AI workspace: connected apps and folders form a "second brain," and agents — chief of staff, research, GTM — work on it with shared memory.

Description

Turnstone is a local-first workspace where AI agents know your context. You connect email, calendar, Slack and folders; Turnstone turns them into a "second brain"/> that agents use to work without re-explaining everything.

Key features

  • An always-updated second brain built from files, apps and browser
  • Role-based agents — chief of staff, researcher, GTM — sharing one memory
  • Everything runs on your own machine orchestrated by OpenClaw
  • Works with any models, including local ones

Pricing and access

The free plan includes the workspace and 50 agent runs per month. The company is backed by Y Combinator (Winter 2026 batch).
