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.

**Small plans** are encoded entirely in the URL hash. No server involved, nothing stored anywhere.

**Large plans** use a short link service with **end-to-end encryption**. Your plan is encrypted with AES-256-GCM in your browser before upload. The server stores only ciphertext it cannot read. The decryption key lives only in the URL you share. Pastes auto-delete after 7 days.

• Zero-knowledge storage, similar to PrivateBin
• Fully open source and self-hostable (see docs)
