Overview

Greptile, founded in 2023, built its own code-understanding engine specifically for indexing and reasoning about large codebases, including sprawling monorepos that stress-test the context limits of more general AI review tools, rather than relying solely on an off-the-shelf language model's context window.

That custom indexing approach is the core technical bet behind its AI code reviews: comments on a pull request draw on an understanding of how the changed code connects to the rest of a large repository, rather than only the diff in isolation. API access lets engineering teams build custom review workflows around the same underlying engine rather than only using a fixed review interface.

There's no free tier; pricing starts around $30 a month per developer. For an engineering team working in a genuinely large monorepo where general-purpose review tools start missing cross-file context, Greptile's purpose-built code graph engine is aimed specifically at that scale problem.
