Sharing Plans

Plannotator lets you privately share plans, annotations, and feedback with colleagues. For example, a colleague can annotate a shared plan, and you can import their feedback to send directly back to the coding agent.

Plans are shared via compressed URL through a static site: share.plannotator.ai

• No backend or database; nothing is stored
• The site's deployment is open source
• You can self-host your own share site and point Plannotator to it via an environment variable ()
