Meet Turnstone

Turnstone is a Mac workspace for building a team of AI agents around context from email, calendars, meetings, and documents. Connected information forms a shared knowledge base, while individual agents maintain their own context for specialized work. Its assistant, Pebbles, helps users choose and configure a team based on their needs.

Ready-made arrangements cover tasks such as meeting preparation, follow-up drafts, content planning, recruiting, and sales research. Users can move between agents in one window, inspect their work, and approve output before it is sent. Turnstone is useful for people who want recurring assistants to work from a consistent understanding of their projects and relationships.
