Browser extension that integrates Git AI Standard attribution data into GitHub pull request interfaces
Note
📖 Read the full article: GitHub Browser Plugin for AI Contribution Blame in Pull Requests Learn more about the motivation, implementation details, and future of AI attribution in collaborative development.
This project extends Refined GitHub with AI contribution tracking capabilities for GitHub pull requests. It provides line-level AI attribution visualization by reading Git AI Standard metadata from git notes, enabling transparent attribution of AI-generated code contributions in collaborative development workflows.
The Git AI Standard provides a vendor-agnostic framework for tracking AI-assisted code contributions across the software development lifecycle. It preserves attribution metadata through git operations (merge, rebase, squash, cherry-pick) by storing data in git notes attached to commit refs. This metadata includes:
- Per-line AI contribution attribution
- Model identifiers and version information
- Original prompts used for code generation
- Linkage between prompts and resulting code
This extension augments the GitHub pull request interface by:
- Reading Git AI Standard Data: Extracts AI attribution metadata from git notes refs during PR diff rendering
- Visual Indicators: Applies syntax highlighting and gutter annotations to AI-contributed lines in the Files Changed view
- Contribution Metrics: Calculates and displays human vs. AI contribution percentages at the file and PR level
- Contextual Information: Provides hover states and detail panels showing model information and generation context
The plugin operates by:
- Hooking into GitHub's DOM rendering pipeline to identify code diff elements
- Fetching git-ai attribution data via GitHub API or local git notes
- Applying CSS classes and DOM modifications to visualize AI contributions
- Maintaining compatibility with GitHub's dynamic page updates and UI changes
- Line-level Attribution: Visual indicators on each line showing AI vs. human authorship
- Contribution Statistics: Summary metrics showing the percentage breakdown of AI contributions
- Model Information: Display of which AI model (Claude Code, Cursor, Copilot, etc.) generated specific code segments
- Toggleable Interface: Feature can be enabled/disabled through extension options
- Full Refined GitHub Feature Set: Retains all features from the base Refined GitHub extension
Detailed installation instructions are available in the project repository. The extension requires:
- Installation of git-ai CLI tool
- Browser extension installation and authentication
- Configuration of git-ai in your development workflow
This is a proof-of-concept implementation serving as a beta prototype for AI contribution attribution in GitHub interfaces.
Key Limitation: The extension relies on GitHub's HTML structure and CSS classes, which may change without notice and cause breakage. This approach is inherently fragile and requires ongoing maintenance to track GitHub UI updates.
This tooling is designed for development teams and projects that:
- Accept AI-assisted contributions and need transparent attribution
- Want to track AI impact on codebases over time
- Need to enforce policies around AI contribution percentages
- Require audit trails linking prompts to generated code
- Desire retrospective analysis of which code segments were AI-generated
Feedback, issues, and contributions are welcome. This project aims to advance the conversation around AI-assisted development practices and attribution standards. Community input on implementation approaches and feature requirements is encouraged.

Browser extension that simplifies the GitHub interface and adds useful features
We use GitHub a lot and notice many annoyances we'd like to fix. So here be dragons.
Our hope is that GitHub will notice and implement some of these much-needed improvements. So if you like any of these improvements, please open a discussion on GitHub feedback or contact GitHub support about doing it.
GitHub Enterprise is also supported: How to enable it.

GitHub took inspiration from Refined GitHub and natively implemented dozens of its features, 🎉 so they've been removed from this extension. You can also see all the past features of Refined GitHub in a single list.
Most features can be disabled if they are JavaScript-based and you can override our CSS with your own in the extension options.
We're happy to receive suggestions and contributions, but be aware this is a highly opinionated project. There's a high bar for adding features. Users will always disagree with something. That being said, we're open to discussing things.
