This free tool is a set of written instructions, a checklist and a template that guide your AI assistant through the job. It works in any assistant and never calls our servers.

  1. Choose Copy instructions above, or view them first.
  2. ChatGPT or Claude: create a Project and paste them into the project instructions, so every chat in that project uses this tool. Or paste them at the start of a single chat.
  3. Ask your question or use an example request, and add the details it asks for.
