Frequently asked questions
Is this tool free?
Yes. Calchemy tools are free to use in your browser.
Is my data uploaded?
No. The tools are designed to run locally in your browser unless clearly stated otherwise.
Do I need to fill in every field?
No - only the fields you fill in are included in the assembled prompt, so you can use as many or as few as your task needs.
Why structure a prompt this way?
Separating role, task, context, format, constraints and tone tends to produce more consistent, on-target responses from AI models than a single unstructured sentence.
