Our Take

Plannotator lets you annotate any document, URL, or folder and send that feedback straight to AI agents. Think of it as a feedback loop between you and your AI systems—no more guessing whether the model actually understood what you wanted. They just launched on Product Hunt and are looking for early adopters to test it out.

This is the kind of tool that makes AI actually usable in real workflows. You want the AI to do something right? You need a way to tell it what right looks like. Plannotator is building exactly that bridge.

Plannotator on Product Hunt →

Interactive Plan Review tool that allows users to mark up and refine Claude Code plans using a UI, share for team collaboration, and automatically send feedback for Claude Code to act on. Select parts of plans for deletion, add comments, or suggest replacements. Also functions as a local plugin (no network requests) that runs entirely in the browser, allowing annotation of any document, URL, folder, markdown, or text and sending feedback directly into integrated agents.

Problem It Solves
Closes the feedback loop between humans and AI coding agents. Currently, users manually paste raw plan text into documents, mark them up by hand, then re-paste back into the agent—a round-trip process that kills momentum and lacks team coordination.
Target Customer
Developers and teams using Claude Code and other AI coding agents who need collaborative plan review and feedback integration.
Use Cases
Annotating Claude Code plans with team feedback, Collaborative review of AI agent plans, Annotating documents, URLs, folders, and markdown, Version tracking for coding agent plans with plan diffs, Sending feedback directly into agent loop, Creating personal LLM wikis in Obsidian
Pricing Details

Differentiator
Runs entirely locally with no network requests - plans never leave the user's machine while closing the feedback loop between humans and agents. Group annotate feature enables team collaboration similar to Google Docs but for coding agent plans.
Why Now
As AI coding agents like Claude Code become more widely adopted, there is a missing piece in the workflow: a way for teams to collaboratively annotate plans and feed that feedback directly back into the agent loop. This product fills that gap.
