AI Code Review Assistant
Executive Summary
Verdict: GO. The plan assumes engineering teams will trust an AI-generated security flag enough to act on it before merge — that's the weakest untested bet behind this idea, not the review-quality feature set itself.
Validation Test
The cheapest real test for the weakest assumption in this plan — Reddit Post on r/webdev.

Draft
I built an AI that reviews PRs and flags security issues before merge — looking for 5 teams to try it free on their next 30 PRs and tell me if it caught anything your existing reviewer missed.
Target Customer
Development teams (5-50 engineers) using GitHub for code review. Primary persona: engineering leads managing PR review bottlenecks. Secondary: solo developers wanting automated quality checks before merging.
Assumed advantage (unverified)
The plan assumes combining AI PR review + security scanning + one-click auto-fix is enough to win teams off CodeRabbit and DeepSource — based on their G2 complaints about false positives and lack of security scanning. This differentiation is untested against real switching behavior.
Key Risks + Refuting Tests
AI hallucination in code suggestions
HIGHRefuting test: Run the confidence-scoring model against 50 real PRs with known-correct fixes and check whether hallucinated suggestions above the 95% threshold actually appear — if they do, the risk is confirmed, not mitigated.
GitHub API rate limits at scale
MEDIUMRefuting test: Simulate 50 concurrent repos hitting the GitHub App at peak load and measure whether the 5,000 requests/hour ceiling is actually reached before assuming queueing is necessary.
Enterprise security concerns with AI code access
MEDIUMRefuting test: Ask 5 enterprise buyers from the interview pool whether a documented zero-retention policy (without full SOC 2, which takes months) is enough to move them past the blocker — don't assume compliance is required before testing it.
GitHub launching native AI review
LOWRefuting test: Track GitHub's public roadmap and Copilot changelog for 90 days for any review-specific (not generation-specific) feature announcement — the assumption fails the moment one appears.
