AI Code Review

AI code review tools connect to a code repository and automatically analyse every pull request, leaving inline comments on bugs, missing edge cases, style inconsistencies, and security anti-patterns before a human reviewer looks at the diff. Tools like CodeRabbit, Greptile, and Qodo have moved from novelty to near-standard practice at many engineering teams by 2026, largely because AI coding agents produce more code, faster, than humans can review manually. AI review reliably catches mechanical issues — missing null checks, hardcoded secrets, inconsistent naming — but does not reliably judge whether a change solves the right problem or fits a product's architecture. It works best as a first pass, not a replacement for human sign-off.
