Q&A
With multiple internal platforms and APIs to maintain in a complex monorepo, Vouch faced challenges with PR review lead times and catching subtle implementation errors that were difficult for human reviewers to detect consistently.
Vouch chose Greptile for its minimal setup requirements and immediate value delivery. The team particularly appreciated the ability to tune prompts for their monorepo structure and the flexibility to control usage through labels.
Greptile has helped catch critical issues around incorrect typing, poor asynchronous handling, improper logging patterns, and incorrect API usage that static analysis tools would not be able to detect.
The integration has enabled developers to receive immediate feedback on code issues, allowing human reviewers to focus on architectural concerns and best practices. The chat feature has become a valuable tool for understanding complex domain aspects of the system.

How Vouch leverages AI to catch subtle implementation errors and improve review efficiency
With multiple internal platforms and APIs to maintain, Vouch's engineering team faced challenges with PR review lead times and catching subtle implementation errors that were difficult for human reviewers to detect consistently. “We saw that some of our most common mistakes were from issues that human reviewers have a hard time reliably detecting but are easy for a trained automation tool to catch every time,“ says Dan Goslen.
After evaluating several AI tools, Vouch chose Greptile for its minimal setup requirements and immediate value delivery. The team particularly appreciated the ability to tune prompts for their monorepo structure and the flexibility to control usage through labels. “We've tuned our prompt to make sure our engineers are using these packages properly in addition to looking for style and logic issues.“
Greptile has helped Vouch catch critical issues around incorrect typing, poor asynchronous handling, and improper logging patterns. The code review summary feature has enhanced human reviewer effectiveness by providing clear context before deep-diving into the code. “We get comments like 'This package exposes an API that looks like this, but you are using it incorrectly', which is very useful. Static analysis tools would not be able to help in that situation.“
