CodeMap4AI – fix hallucinations in ChatGPT with a project code map

Hi HN,

I’ve been using ChatGPT and Claude for coding help, but once my web projects got larger, the models started hallucinating — guessing functions, forgetting file relationships, or breaking logic across files.

I built a small tool to solve this: CodeMap4AI

It scans your project and generates a code_map.json — a structured snapshot of the logic, dependencies, and file layout. With that, LLMs like ChatGPT get the context they need, and the hallucinations drop significantly.

It runs locally in the browser, and currently supports web-based projects (PHP, JS, HTML, CSS). Feedback welcome — would love to hear if it helps others too.
