As answered by people managing e.foundation /e/ and CodeMap4AI.
CodeMap4AI's answer:
CodeMap4AI creates a lightweight, structured JSON map of your entire project that can be instantly understood by AI assistants like ChatGPT. Unlike most AI tooling, it works independently of your IDE, and it’s purpose-built to reduce AI hallucinations and improve the accuracy of code-related prompts.
CodeMap4AI's answer:
Because it provides clean, AI-ready context without requiring IDE integration or sending code to external servers. It’s fast, private, and works well in any setup — from local terminals to AI chat interfaces. It’s also helpful for humans, offering a high-level view of any codebase in seconds.
CodeMap4AI's answer:
Developers who use AI tools (like ChatGPT, Claude, or Copilot) to write, refactor, or understand code — especially those working on large, unfamiliar, or legacy projects. Also ideal for freelancers, indie developers, and teams onboarding new engineers.
CodeMap4AI's answer:
CodeMap4AI started as a personal tool to stop ChatGPT from hallucinating when working on real-world PHP/JS projects. The creator realized that by giving the AI a clear map of all files, classes, and DB logic, its answers became dramatically better — so the tool was refined and released for public use.
CodeMap4AI's answer:
CodeMap4AI's answer:
As of now, CodeMap4AI is growing and used mostly by indie developers, freelancers, and small teams.
