ctxt.sh - AI-powered codebase documentation and navigation tool
Published Feb 24, 2026
🔴 Problem Identified
Developers waste significant time (weeks) trying to understand new codebases, legacy code, or inherited projects. Traditional code exploration is manual and time-consuming, requiring developers to search through files, commits, and PRs to understand system architecture and locate specific functionality.
💡 Proposed Solution
An AI tool that indexes entire repositories (code, commits, pull requests) and allows developers to ask natural language questions to instantly find specific code locations, understand functionality, and navigate complex codebases. Uses semantic search to provide exact file and line number locations.
