Show HN: Gnosis – Turns pull requests into guided walkthroughs

Like many of us, I've been using Claude Code to do most of my coding and the coding part got fast, but reviewing still sucks. So either we degrade into not reviewing at all or we need to find a better way to do it. So this is my experiment to reinvent reviewing.

I've come to hate GitHub's diff view, trying to understand what it actually did. The files are shown in whatever order GitHub decides. No logical grouping. No sense of what depends on what. So with Gnosis, you paste a PR URL (or browse your open PRs), pick a model (Claude or Gemini), and it reads the diff, groups changes in a logical way, and presents them as a slideshow. Each slide explains why the change exists and shows the relevant diff. You can even comment, approve, or reject the PR directly from the tool.

It runs locally as an Electron app, to be able to use your local agent CLI tools, so it can use your existing subscriptions rather than rely on API tokens.

It´ve personally found it really useful and I would love to get feedback on how to improve it. Or even better, PRs into the repo ( guess how I will review them :)
