AI code review that actually fixes your code
Other tools leave comments on your PRs. LGTM creates fix commits. It doesn't just tell you what's wrong — it fixes it.
Free tier included · No credit card required · 2 min setup
Works with any GitHub repo
How it works
Three steps. Zero config.
From install to your first AI-powered fix commit in under two minutes.
Install the GitHub App
One click to add LGTM to your repos. No config files, no YAML, no CI changes.
Open a pull request
Push code and open a PR like you normally would. LGTM kicks in automatically.
Get review + fix commits
LGTM reviews your code, leaves inline comments, and pushes fix commits directly to your branch.
Features
Everything you need. Nothing you don't.
Built for developers who want their PRs reviewed and fixed, not lectured.
Auto-fix commits
Not just comments — LGTM pushes fix commits directly to your PR branch. Review the diff and merge.
Inline PR comments
Get contextual, line-level feedback explaining what was wrong and why the fix works.

Uses the best AI model available for deep code understanding. Not a wrapper around GPT-3.5.
Reviews in minutes
Most reviews complete in under 2 minutes. No waiting hours for CI to finish.
Free tier included
20 reviews per month on the free plan. No credit card required to get started.
Secure by default
Your code is never stored. Reviews happen in real-time and results are posted directly to GitHub.
The difference
Comments vs. commits
Other tools tell you what's wrong. LGTM fixes it.
⚠️ Warning: This function doesn't handle null values.
Consider adding a null check on line 42.
Also, the variable name `x` could be more descriptive.
You might want to add error handling here.
- function process(x) {
+ function processUserInput(input: string | null) {
+ if (!input) throw new ValidationError(...);
