Thraft

Thraft is a planning tool built on one belief: planning with agents should be document collaboration, not chat. A plan in Thraft is a living draft of typed blocks. You annotate it in place, fork it where thinking diverges, and see exactly what changed since you last read it.

Thraft runs on macOS. Download the latest release.

Thraft was called Plano before version 0.2.0. Until 0.2.0 is out, the download is still named Plano. When 0.2.0 is out, the app offers you the update to Thraft.
