Products that do what Code Review · Plannotator does

Code review environment for the modern era.

  1. 1CR

    Plannotator opens a local diff viewer (git, jj, p4). You annotate lines, tokens, or comment on files, and when you're done they feed straight into your agent session; creating an automated feedback loop. It works on local diffs, commits, branches, worktrees, and GitHub/GitLab PRs. The PR view lets you annotate the descriptions and comments while also being able to filter bot comments. The core tool enables focused manual review, the optional AI layer: - Ask AI: Ask questions directly inline - Guided Reviews: Have an agent reorganize a large diff into semantic overview sorted by…

    I started this in January as a hook for Claude Code's plan mode: when it finished planning, instead of approving a wall of text in the terminal, the plan opens in your browser and you could mark it up like a document. Your annotations go back into the agent session. It grew from there. There's now PR-style code review (git, jj, p4, GitHub/GitLab PRs) and annotation for markdown, URLs, and folders. Agents produce a lot of HTML now, so Plannotator renders those artifacts and lets you annotate them too. Nine harnesses are supported: Claude Code, Codex, Copilot CLI, Gemini, OpenCode, Kiro,…

    I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…
