Timeless (formerly timeOS)

What is Timeless (formerly timeOS)?
Timeless is a project management and meeting assistant that turns spoken conversations into tracked tasks and automated agent workflows. It records meetings without sending a bot into the call, writes notes in 60+ languages, and flags moments in a discussion that should become follow-ups or delegated work. Rooms group conversations by client, project, or topic so related meetings stay in one workspace.
Where most meeting note tools stop at a transcript and summary, Timeless wires those moments into agents that can draft emails, schedule follow-ups, and push tasks into tools like Notion or Google Drive. The trade-off is focus: it is built around live conversation capture and moment-based triggers rather than broad kanban boards or Gantt planning.
Freelancers and small teams use it to replace manual note-taking and post-meeting admin. Product and customer-facing teams lean on Rooms and Squads to keep context across recurring calls. Builders on the Max plan get API, MCP server, and webhook access to run their own automations off meeting data.
