Greptile builds AI agents that review code. Its platform indexes a customer's whole codebase as a graph and then runs a swarm of parallel agents over each pull request on GitHub or GitLab, flagging logic bugs that span multiple files, security risks and style violations before a human reviewer sees them. Teams can state custom review rules in plain English, and the system keeps learning from the comments a team leaves on its own PRs. The company was founded in 2021 by Daksh Gupta, Soohoon Choi and Vaishant Kameswaran, is based in San Francisco, and says it serves over 22,000 teams including Brex, NVIDIA, Zapier, PostHog, Retool and Klaviyo.
What sets it apart
Reviews are grounded in a graph index of the entire repository rather than the diff alone, which is what lets the agents catch logical bugs that only appear across several files; its TREX agent goes further and actually executes the branch in a sandbox, writing and running tests instead of only reading the code.
An AI code review platform that automatically reviews pull requests in GitHub and GitLab using a swarm of agents working from a graph index of the full codebase.
