Greptile is an AI-powered code review tool designed to help developers merge pull requests faster and catch more bugs by providing the full context of the codebase.
However, it is important to note that the tool doesn’t just look at the new code in your pull request — it reads your whole codebase like a novel. Every function, every file, and every little corner of the code to learn how everything connects. So, when someone changes something, Greptile knows what it affects. That’s a big deal as missing that link is how bugs sneak in.
Say a developer on a fast-moving team opens a pull request late Friday. They fix a bug in one file, but that file talks to five others. Normally, the reviewer would have to trace each link by hand. With Greptile, the AI already knows those links. It reads the change, checks how it ripples through the codebase, and leaves comments where it spots problems. In a way, this is like having an engineer who never sleeps.
Moreover, Greptile explains code in plain English, telling you what the change does, and why it might matter. Some say it catches 3x more bugs than humans, while others claim it cuts review time down by 75%. Those aren’t small wins when you think about it. They save companies days of work, and stop bad code before it hits production.
Greptile plugs right into GitHub and GitLab, and can even pull in tickets from Jira and/or notes from Notion. That way, it gets the bigger picture — what the code is trying to do, not just what it does. You can also teach it your style guide, so it catches stuff the way your team likes it. It learns fast and adapts to you and your needs.
Greptile is usually compared to tools like Amazon Q, Codacy and Qodo. However, it stands out because it sees both the forest and the trees. It understands your codebase, top to bottom, and gives feedback with real context. This makes Greptile ideal for busy dev teams, fast-moving startups, and large codebases with lots of moving parts. Pretty cool, right?
