Frequently asked questions

Does it expose technical details?
No. It keeps the user-facing copy plain and suggests a separate detail string for logs or a 'show details' toggle when the cause is technical.
Will it make things up?
The prompt instructs the model to stay grounded in what you type, but it is a first draft. Read it before you ship it, and add more detail to your input for a sharper result.
Is this really free?
Yes. Every run is free, with no account, credit card, or email required. We build these because the people who need them often end up wanting a full interactive product demo too.
