AI Summary

Glassbox is a local browser-based code review tool designed for iterating on AI-generated changes by annotating diffs and exporting structured feedback that AI assistants can directly apply.

How It Works

1
🔍 Discover Glassbox

You hear about a simple tool that makes reviewing AI-generated code changes quick and precise, turning your feedback into something AI can instantly understand and fix.

2
🚀 Install and launch

With one easy command in your project folder, Glassbox installs and opens a browser window showing all the code changes ready for review.

3
📂 Browse your changes

See a clear list of files that changed, grouped by folder, with side-by-side views highlighting what's new, removed, or the same.

4
✏️ Add your feedback

Click any line to leave notes like 'bug here' or 'try this style,' drag them around, and watch your expert insights build up organized by file and position.

5
🧠 Get smart guidance

Switch to risk view to spot issues first or reading order to understand changes logically, with helpful notes explaining key parts.

6
✅ Finish and share

Hit complete to create a neat summary file your AI reads directly, telling it exactly what to fix, style, or remember next time.

🔄 Perfect loop achieved

Your AI applies the feedback, you review again even faster, and your code gets better with every quick cycle—no more manual rewriting.

AI-Generated Review

What is glassbox?

Glassbox is a local TypeScript CLI tool that spins up a browser-based diff viewer for reviewing AI-generated code changes in any git repo. Run `npm install -g glassbox` then `glassbox` to annotate lines with categories like Bug, Style, or Remember, and export structured markdown feedback that AI tools can parse and apply directly. It handles uncommitted changes, commits, or branches, with persistence across restarts and smart reuse of prior reviews.

Why is it gaining traction?

Unlike GitHub PRs or editor diffs, Glassbox delivers a tight local loop: review, annotate, export—no accounts or waiting—for AI coding workflows. Optional AI analysis ranks files by risk (security to performance) or suggests reading order, plus guided notes for newcomers, all via local API keys. As a local GitHub Copilot alternative, it stands out for privacy-focused devs ditching cloud runners.

Who should use this?

AI-heavy devs iterating on Cursor, Claude, or Copilot outputs who hate manual rewrites. Frontend/backend teams reviewing multi-file changes without PR overhead. Beginners onboarding codebases, thanks to educational guided reviews.

Verdict

Try Glassbox if AI code review is your bottleneck—its annotation categories and export format enable real iteration gains. At 18 stars and 1.0% credibility, it's early (light tests, solo maintainer), but polished docs and zero telemetry make it low-risk to eval as a local GitHub actions runner alternative.
