In simple English
This tool helps you research stocks using the methods of Warren Buffett and other famous investors. It uses artificial intelligence to look at company data, check financial statements and find risks. It forces the computer to give clear conclusions instead of vague answers. You can run it inside command-line tools like Claude Code or Codex. It costs nothing for the software, but running large models requires an active API subscription.
