Show HN: I built my own knowledge graph from the code AI writes (github.com)

A new tool called Learnlance has been introduced, allowing users to create a personal knowledge graph from code generated by AI coding agents like Claude Code, OpenAI Codex, and GitHub Copilot. By monitoring coding sessions, Learnlance extracts concepts and terminology from the AI's outputs and organizes them into a browsable knowledge graph. Each time the AI writes or edits code, Learnlance captures these insights and generates an interactive HTML graph, helping developers visualize and retain knowledge over time. This innovation is significant for the AI/ML community as it enhances the learning experience for programmers by integrating real-time concept extraction directly from AI-generated code. Key features include delta encoding for data synchronization, a background analysis process, and hooks for various coding agents, ensuring seamless integration. The tool requires no API key and focuses on creating an efficient learning environment without interrupting coding sessions, making it a valuable resource for both beginner and experienced developers interested in improving their coding skills through AI support.
