ExplainThisRepo scans a codebase's configuration files, entry points, and dependencies to create a clear summary of what the project does and how it's organized. It helps you quickly understand unfamiliar repositories without reading every file. The tool outputs an EXPLAIN.md file with architecture insights.
ExplainThisRepo is a developer tool that provides the fastest way to understand any unfamiliar codebase by analyzing real project signals rather than relying on blind AI guessing. It extracts deterministic signals from configs, entrypoints, manifests, dependency graphs, and high-signal files to produce a structured EXPLAIN.md file. The tool supports multiple input types: GitHub repositories (public/private), local directories, monorepos, and even individual files. It offers quick, simple, and detailed analysis modes, and can output explanations as markdown, PDF, DOCX, or plain text. Installation is available via pip, npm, .NET global tool, or standalone binaries. ExplainThisRepo solves the 'garbage in, garbage out' problem by feeding LLMs with high-quality, deterministic repo signals, ensuring accurate architectural summaries.

When analyzing private repositories, the tool processes code locally; however, if using an LLM backend, code may be sent to external APIs. Ensure compliance with your organization's data policies.
The tool may inadvertently expose sensitive information if the codebase contains secrets in configuration files. Review the output before sharing.
