Questions

Does this tool send my prompt to an AI?

No. It only builds the text in your browser. You copy the prompt and paste it into the assistant you already use.

Which AI assistants does it work with?

Any assistant that accepts text, including ChatGPT, Claude, Gemini and Copilot. The structure of role, task, context and constraints works across all of them.

Why give the AI a role and constraints?

A role sets the expertise and voice of the answer, and constraints tell the model what to include or avoid. Both reduce the back and forth needed to get a usable result.
