Show HN: Open-source+local Cursor for code review (use this instead of GitHub)

Hey again HN. Isaac and I originally released a voice-first code review tool, but have since open-sourced it and turned it into just a better way to review your and your team's Github PRs.

Main things we've heard that make code reviews slower are:

1) PRs are too big and overwhelming 2) Need to jump around to find the right context and relevant code 3) Need to spend time thinking (should not be a thing since AI exists), and writing comments

What we built to address these:

1) PRs are split up into sub-PRs without needing to actually split them up and stack them yourself -> Automatically done with AI -> Features a CLI you can use in place of `git push` where you can control how many sub-PRs it should split them into, with a guiding message for how they should be split up (otherwise it will decide on its own) -> When you want to split and merge a PR lower in the stack, you can do so 'just-in-time'

2) Brought all context (comments, diffs, file-tree) into one IDE-like UI -> When you ask the AI anything, it pulls up a view of all of the relevant code sections that would be helpful to have in view while reading its response -> Unlike Github, which has separate tabs for discussion and file changes, everything is consolidated into one view -> You can press and highlight comments/code to automatically include them in the chat context, just like Cursor

3) Cursor-like chat pane to use the AI as a review partner as you go through it -> Ask dumb questions - nobody will know -> Use voice mode to speak your thoughts/comments to the AI as they come (like a live review session with a colleague) -> It'll auto-draft comments for you based on your discussion with it -> Suggestion bubbles for one-click common questions to code or comments (e.g. What are some counter-arguments to this comment? What are some potential concerns with this piece of code? Can you explain this part to me? etc.)

Simple to get started - just follow the README instructions and ping here or create an issue if you have any problems.

When you enter the dashboard, you'll see all the PRs you're involved in. You can also paste in a public Github PR URL to try it out. Or, like I said, use the CLI to create a draft PR of your working branch with split sub PRs and view it in LightLayer.

We vibe-coded a good chunk of this tbh, so it's not perfect and not everything's finished (see README for incomplete features) - feel free to contribute :)

Hope this helps you get through your code reviews quicker!!
