Huge PR Replay

Breaks a massive PR into the author's logical steps so reviewers save hours

Problem

On HN, a developer openly complained about receiving giant PRs, and another built Chronosphere to rebuild a PR in logical steps. Reviewers of big diffs struggle to reconstruct the author's train of thought and often need to clone the whole repo just to review a patch. The cognitive cost per PR is high and growing.

Solution

Accept PRs via GitHub App or upload. Automatically regroup the diff into a sequence of small logical steps by file, function, and intent, each with a one-line explanation. Produce a shareable review page with inline annotations that works without cloning the repo and can be embedded alongside existing PR views.

Users

Open-source maintainers, tech leads at small teams receiving external contributions, engineers reviewing AI-generated code

MVP

GitHub webhook to fetch PR diffs; LLM-based logical step splitting; step-by-step review page with inline comments; shareable link export

Revenue

Per-repo subscription (free for individuals, $19–49/mo for teams); metered per PR for private repos; later a self-hosted enterprise edition

Why now

AI coding is inflating PR sizes and review is the bottleneck; LLM diff comprehension just crossed the usability threshold, and incumbents haven't gone deep in this niche
