# PR Understanding Checker

PR Understanding Checker is a product idea in the devtools category at difficulty 2/5, with strong market demand and an estimated revenue potential of $1k-5k/mo.

## Summary

A tool that automatically asks developers comprehension questions about their own pull requests to ensure they understand the code they're shipping. Solves the problem of AI-assisted code that developers can't explain, targeting engineering teams and code reviewers.

## Why this is interesting

The surge in AI-assisted coding via Copilot, Cursor, and similar tools has created a genuine and widely-discussed problem: developers merging code they didn't write and can't fully explain, which engineering managers are actively complaining about on forums and in engineering blogs right now. No clear incumbent owns this space, though some code review tools like Graphite touch adjacent territory around PR quality. The $1k–5k/mo revenue band is realistic for a lightweight GitHub/GitLab integration sold to small engineering teams, but the ceiling is low because budget-conscious teams will resist per-seat pricing for what feels like a process add-on rather than a core tool. The biggest risk is that most engineering teams will view comprehension checks as punitive or infantilizing, killing adoption from the bottom up even if a CTO signs on.
