Plannotator

About Plannotator

Plannotator is a browser-based tool for annotating, reviewing, and sharing AI-generated plans. It runs locally as a plugin/hook and keeps plan content and annotations on the user's machine, avoiding external network requests.

Review

Plannotator focuses on lightweight plan review workflows: mark up sections of a plan, add comments or suggested replacements, and share those annotated versions with teammates. Its local-first, link-based sharing approach makes it a privacy-conscious option for teams that want quick feedback loops without a centralized backend.

Key Features

• Select and annotate exact parts of a plan (mark for deletion, add comments, suggest replacements).
• Interactive plan review UI with inline markup and usernames for contributors.
• Share annotations via compressed, self-contained links that do not require a server to store content.
• Automatic forwarding of collected feedback back to an agent's plan mode so suggestions can be applied programmatically.
• Runs entirely in the browser with no network requests from the tool itself.

Pricing and Value

Plannotator is offered free and the codebase is published publicly, so there are no upfront licensing costs. The core value is strong privacy and control: because annotations and plans stay local and shared links are self-contained, teams can review sensitive plans without relying on a centralized service. This makes the tool especially attractive for small teams, individual engineers, and projects where keeping data off third-party servers is a priority.

Pros

• Local-first operation keeps plans and annotations on the user's device, improving privacy and security.
• Simple, focused UI that makes it easy to highlight exact plan segments and propose concrete changes.
• Link-based sharing is convenient for quick feedback cycles and does not require a backend or account creation.
• Open approach with publicly available source code supports auditability and customization.

Cons

• Collaboration features are basic today; there is limited support for long-term versioning or merge-style workflows.
• Link-based sharing can become hard to manage at scale (multiple revisions, many contributors) without additional coordination or tooling.
• Integration work is needed to import multiple collaborators' annotations into automated feedback flows in larger teams.

Plannotator is best for engineers, small teams, and reviewers who need a lightweight, private way to annotate and share AI-generated plans in the browser. If you require advanced version control, enterprise collaboration features, or centralized audit trails, expect to pair Plannotator with additional tools or workflows. For quick plan reviews and privacy-focused sharing, it offers a practical, low-friction solution.
