Developers reviewing PRs feel overwhelmed by giant diffs and want guided, step-by-step review flows (chapters, logical splits)
Target User
Engineering teams at small-to-mid size startups doing heavy AI-assisted code generation
Product Idea
A GitHub App that auto-chapters large PRs into logical review stages and walks reviewers through them with inline explanation
Evidence
“a code review tool that guides you through reading a PR step by step, instead of piecing together a giant diff”
https://news.ycombinator.com/item?id=47796818“I like the chapters thing, a lot of PRs I review should really be like 5 prs so its nice to have it auto split like that”
https://news.ycombinator.com/item?id=47796818“context switching from managing 2-3 agents at a time... subtle bugs that compound and reviews become 100x more painful”

Why this opportunity matters
This opportunity surfaced from multi where Engineering teams at small-to-mid size startups doing heavy AI-assisted code generation are actively describing the problem in their own words. We classified the demand intensity as medium — meaning the problem is consistent enough that multiple users are searching for a fix, even if they have not committed to paying yet. When users self-select to post a problem on a public platform like multi, they are usually already trying to solve it — which makes them strong candidates for the right paid alternative.
How to validate this before you build
Before writing a single line of code, three lightweight steps will tell you whether this opportunity is worth pursuing:
- Read the original conversation. The evidence links above lead to the exact threads where users described this problem in their own words. Read every comment — what people argue about in the replies often matters more than the original post.
- Talk to five real users. Find five people who match the target user description above and ask how they handle this today. You are looking for two signals: a consistent workaround they hate, and a willingness to pay for something better. If both show up in three of five conversations, the demand is real.
- Test willingness to pay before building. Put up a one-page landing site describing the proposed product, with a deposit or pre-order checkout. If even a small fraction of traffic converts to a real payment, you have validated more than most products that ship to production.
