From the README
Interactive Plan Review for AI Coding Agents. Mark up and refine your plans using a visual UI, share for team collaboration, and seamlessly integrate with Claude Code, OpenCode, Pi, and Codex.
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. The data never leaves your browser.
Large plans use a short link service with end-to-end encryption. Your plan is encrypted with AES-256-GCM in your browser before it's uploaded — the server stores only ciphertext it cannot read. The decryption key lives only in the URL you share and is never sent to the server. Pastes auto-delete after 7 days.
