Questions and Answers

As answered by people managing e2b and CodeMap4AI.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe your primary audience?

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.

What's the story behind your product?

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:

  • PHP (core project scanner)
  • JavaScript (for frontend and helper utilities)
  • Bash / CLI scripting (for automation)
  • JSON (for structured output)
  • Apache

Who are some of the biggest customers of your product?

CodeMap4AI's answer:

As of now, CodeMap4AI is growing and used mostly by indie developers, freelancers, and small teams.
