Questions and answers

Is anything added that is not in the input?

The AI writes only from the supplied facts. Numbers, dates and amounts that are not in the input stop the result, and promises such as a guarantee are reported for review.

Is this a legal dunning notice?

No. The tool writes a text. Legal requirements, interest and fees are not checked.

Is the draft ready to send?

No. It is a draft. Nothing is sent or published, and the text has to be read and approved before use.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?
