logPhase

logPhase is an AI-powered desktop application that translates pull requests into visual user journeys to accelerate code comprehension.

logPhase is a macOS application designed to help developers build code comprehension as AI generates code at machine speed. By pasting a pull request link, the app clones the repository, analyzes the changes, and uses Claude Code to generate flow diagrams of user journeys. It visualizes repositories as interactive city maps where user journeys appear as glowing trails across services, packages, and files. Developers can inspect methods behind each step, chat with Claude about specific code behavior, split steps, and review modified lines. It supports Java, Kotlin, C#, Python, and TypeScript, running locally with offline support for most languages.
