Today is a special day for us here at Graphite. In just one year since our public launch, we’ve become the developer productivity platform for tens of thousands of engineers at top companies including Snowflake, Asana, Ramp, Square, and many more. We’ve crafted every part of Graphite to simplify and accelerate the way the world’s best teams build software, and we’re so excited to announce a new feature that represents a step-function improvement to the Graphite workflow.
LLMs have transformed the way we build software over the past few years, making us more productive engineers than ever. But with the sheer amount of new code produced, our tools and processes for reviewing, testing, and deploying code changes are struggling to keep up. The world’s fastest teams need a new developer toolchain for the age of AI, and today we’re shipping the first major piece of that puzzle.
Graphite Reviewer
We're excited to introduce Graphite Reviewer, an AI companion designed to help you review pull requests as quickly as you can write—or generate—code. Think of Graphite Reviewer as an always-online teammate, that delivers consistent, high-signal, actionable feedback on every pull request in seconds. Best of all, Reviewer is built directly into your Graphite dashboard, where you already give and receive feedback, and it seamlessly syncs with GitHub.
What really makes Graphite Reviewer stand out is its accuracy. We've focused relentlessly on cutting through the noise and eliminating the hallucinations that often plague other AI tools. AI only feels like magic when it’s consistently helpful and trustworthy, and Reviewer has achieved a <3% false-positive rate across tens of thousands of code changes reviewed.
Features
We can’t wait for you and your team to try out Graphite Reviewer. Here’s what you can expect:
A second pair of eyes: Graphite Reviewer automatically scans opened PRs for bugs, logical errors, and other areas for improvement.
Instant feedback: Graphite Reviewer provides authors with immediate, actionable feedback, allowing them to squash bugs in their PRs before teammates even start their review. This enables reviewers to focus on the big picture rather than getting caught up in typos and stylistic nits.
More signal, less noise: Other AI bots hallucinate and create noisy comments. Graphite Reviewer is calibrated to catch real bugs and deliver smarter, targeted feedback with fewer false positives.
Codebase awareness: Graphite Reviewer uses RAG (Retrieval-Augmented Generation) on your team's past pull requests to ensure that every piece of feedback makes sense in the context of your codebase.
Custom rules: Define and enforce custom patterns tailored to your codebase, including regex matching to catch things like secrets and API keys. You can also create personalized AI prompts to enforce your team’s code style rules in plain English. (Coming soon)
Zero set up: Enable Graphite Reviewer in any repo with the click of a button and instantly start receiving codebase-specific feedback on new pull requests.
Reviewer is now available to all teams on Graphite and is free for the month of October. Simply enable it for your repo(s) in settings, and Reviewer will start working right away. If your team isn’t using Graphite yet, you can sign up with GitHub to unlock a 30-day free trial of the full Graphite platform. After the trial expires, Graphite Reviewer is a $20/active repo committer/month add-on to your team’s Graphite subscription.
For our team at Graphite, along with hundreds of external beta testers, Reviewer has become an indispensable part of our engineering workflow, saving us hours of valuable maker time every week. We’re so excited to hear what you think of Reviewer, and we can’t wait to share more product updates soon!
