About

A desktop app for macOS, Windows and Linux that gives a spoken walkthrough of a pull request or codebase. The user holds Space and asks a question, and the app answers aloud while highlighting the relevant code and building a live visual from a code knowledge graph. It is aimed at engineers and PMs who need to understand AI-written code as quickly as agents produce it. Voice runs on the user's own OpenAI or ElevenLabs key or the system voice, and the site states code does not reach its servers.
