ai code review

A review that reads the whole codebase, not only the diff.

Every pull request gets a senior-level review within minutes. CodeReviewer reads your repo as it'll look after the change. It only comments where it can show you why.

Export ignores the caller's workspace. Any signed-in user could pull another tenant's invoices.

the problem

Diff-only review misses the bugs that hurt.

Reviewers are busy, so pull requests wait hours for a first look. By the time feedback lands, the author has moved on.

Reviewers see the changed lines. They don't see the fourteen other places that call the function you just touched.

Conventions live in people's heads. New teammates break them, and nobody notices until the incident review.

how it works

From trigger to result.

A pull request opens

CodeReviewer picks it up on its own. No bot command, no queue.

It reads everything

The whole repo as it'll be after the merge, plus your spec and your house rules.

It traces the impact

It follows the change into callers, data paths and tests, across files.

It comments with receipts

Findings land on the exact lines in GitHub. Each has a severity, a category and a suggested fix.

capabilities

What you get.

Whole-codebase context

Findings point at the other files that prove the point ("the rest of the app counts in cents"), not generic advice.

Severity you can triage

Critical, major, minor or nit. Fix what matters first and skim the rest.

Eight categories

Bugs, security, performance, structure, tests, docs, style and scope. Filter to what your team cares about.

Your house rules

A small config file in the repo teaches CodeReviewer your conventions, paths to ignore and how to build the project.

Learns from dismissals

When your team keeps dismissing the same kind of finding, it shows up as a pattern. Then the reviewer stops raising things you've already decided.

Fixes one click away

Any finding can become a committed fix. It's checked to compile before it touches the branch.

Why whole-codebase context changes the review

A diff tells you what changed. It doesn’t tell you what the change breaks. The bugs that reach production usually sit one hop away from the edit: a caller that relied on the old behaviour, a second code path that formats the same data differently, a permission check that the new endpoint forgot.

CodeReviewer builds the repo as it’ll look after the merge and follows the change outward. Its findings cite that evidence: the file and line that sets the convention, or the caller that will break. So a reviewer can accept or reject a comment in seconds, without working it all out again.

What a finding looks like

Each finding has four parts: where (file and line), what (a one-sentence statement of the problem), why (the evidence from elsewhere in your code) and the fix (a concrete change you can apply with one click). If CodeReviewer can’t produce all four, it doesn’t post the comment.

faq

Questions, answered.

Does it replace human reviewers?

No. It takes the first pass on correctness, security, conventions and missing tests. Your reviewers get to spend their time on design and product calls instead of typos and null checks.

How noisy is it?

Not very. CodeReviewer only comments where it can point at evidence in your code. Every finding has a severity, and anything your team keeps dismissing gets flagged so you can tune it out.

Which languages does it support?

It reviews the languages and frameworks modern web, backend and mobile teams use every day. Because it reads the whole repository, it follows your project's own patterns rather than a fixed rulebook.

Where do the comments show up?

Right on the pull request in GitHub, on the exact lines, plus a summary. You'll also find them in the CodeReviewer dashboard with filters and history.

How is our code handled?

We only access your code to do the work you ask for: reviewing, fixing and testing your pull requests. Access is limited to the repos you install CodeReviewer on. Our Trust & security page covers access, retention and deletion in detail.
