What they do

Problem

Large teams and AI agents struggle to understand massive, complex codebases quickly, slowing onboarding and causing poor code context and hallucinations.

Solution

An open-source, on-prem code understanding platform that enables instant regex search across millions of lines and Q&A over thousands of repositories using reasoning models.

Who it's for

Developers and enterprise engineering teams (and their AI agents) working with large multi-repo codebases.
