A good offer deserves a short personal letter. This tool writes the subject line, greeting, text and closing from notes about the job and the customer. Offer number, amount, validity and sender are added word for word by the server, so the letter cannot change them. Promises that are not in the input are reported.

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.

Does this tool calculate the offer?

No. It writes the accompanying letter. The quote builder calculates offers from supplied items.

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).
