Code Review Enviornment for the Modern Era

What it does

A local diff viewer for reviewing agent-written code — git, jj, Perforce, and GitHub/GitLab PRs. Annotate lines and files; your notes feed straight back into your agent session. Optional AI layer: inline Q&A, guided reviews, and launchable review agents. Free, MIT / Apache-2.0, runs on your machine.

Plannotator opens a local diff viewer for git, jj, and Perforce. You annotate lines, tokens, or whole files, and when you're done the notes feed straight into your agent session — an automated feedback loop. It works on local diffs, commits, branches, worktrees, and GitHub/GitLab PRs. The core tool is manual; the AI layer on top is optional and answers to you. Free, MIT / Apache-2.0, with local review data kept on your machine by default. Review any changeset with nothing between you and the diff. No model in the loop unless you put one there. Select lines, a single token, or a whole file, and leave a comment, a concern, or a suggested edit. Conventional Comments labels are there if your…from plannotator.ai

In the maker’s words, at launch

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…

  PlannotatorApr 2026 · github.com · ▲97

  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,…

  Hi HN, I’m Valentin, a developer who’s found code reviews to be a slow process, especially after context switching or juggling different projects and languages. Even reviewing my own code can be tough when I’ve lost the thread or just need a fresh perspective. Over the past few weekends, I built GitReviewed to make PR reviews faster, smarter, and genuinely useful for real teams. What it does: - Reviews any GitHub or GitLab pull/merge request with AI-powered comments, spotting security issues, code patterns, typos, and more - Posts comments as you (not a bot), so feedback fits naturally…

  Tool to Automatically Create Organized Commits for PRs2025 · github.com · ▲76

  I've found it helps PR reviewers when they can look through a set of commits with clear messages and logically organized changes. Typically reviewers prefer a larger quantity of smaller changes versus a smaller quantity of larger changes. Sometimes it gets really messy to break up a change into sufficiently small PRs, so thoughtful commits are a great way of further subdividing changes in PRs. It can be pretty time consuming to do this though, so this tool automates the process with the help of AI. The tool sends the diff of your git branch against a base branch to an LLM provider. The LLM…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
