How to get a contract written by ChatGPT or Claude signed
ChatGPT and Claude are quick at drafting a service agreement or a simple rental contract, but what you get back is text in a chat. To get it signed, it has to become a document with a signature line, a date and blanks the other person fills in. Here are two ways to do that, and what to check before anyone signs.

Way 1: let the AI save it as a template
If SignMaster is connected to Claude or ChatGPT, the assistant can hand the contract straight over. SignMaster lays the text out as a clean PDF, with your company name at the top and page numbers at the bottom, and puts a field on every blank.
- 1
Ask for the contract
“Write a one-page snow removal agreement between my company and a homeowner: per-visit price, a 2-inch trigger depth, the season dates, and a signature for each side.”
- 2
Edit it in the chat
Ask for changes until the wording is right: a cancellation clause, a different payment term, plainer language.
- 3
Save it to SignMaster
Say “save this in SignMaster as a template.” The template appears in your Templates list with fields for the homeowner's name, the price, the dates and both signatures.
- 4
Send it
Ask the assistant to start a draft for your customer and send it, then approve the send in SignMaster. Or open the template in SignMaster and send it yourself.
Way 2: paste it into a document
- 1
Copy the text into Word or Google Docs
Fix the formatting, add your logo if you like, and leave clear blanks where the customer's details go.
- 2
Save it as a PDF
In Word, use File › Save As › PDF. In Google Docs, use File › Download › PDF document. A PDF keeps the layout exactly as you see it.
- 3
Upload and place fields
In SignMaster, start a new envelope, upload the PDF and drag a signature, a date and text fields onto the page for each signer. Or type text tags in the document first and the fields place themselves.
- 4
Send it for signature
Add the signer's name and email and send. They sign from the email link in any browser. Save it as a template first if you'll send it again.
Check these before anyone signs
- The parties. Your legal business name and the customer's full name, spelled the way they appear on their ID or company records.
- The work and the price. A scope someone else could read and agree on, the total or the rate, and when payment is due.
- Terms you didn't ask for. Assistants sometimes add clauses, deadlines or penalties nobody discussed. Delete anything you can't explain to the customer.
- Your state's required wording. Some contracts must include specific notices. Home improvement contracts in California, for example, have to carry set disclosures and the contractor's license number, and many sales made at a customer's home need a three-day cancellation notice under the FTC's Cooling-Off Rule.
- Whether it needs a lawyer. For large jobs, employment, real estate or anything you'd hate to lose in court, have a lawyer read it. An AI draft is a starting point, not legal advice.
Prefer to start from something already laid out? Our contract templates cover common jobs, and every one can be edited before you send it.
Questions? Answers.
Is a contract written by ChatGPT legally binding?
It can be. Who typed the words doesn't decide it; the usual rules for any contract do. See is a contract written by ChatGPT legally binding for what to watch.
Can the AI put the signature fields in for me?
With SignMaster connected, yes: when the assistant saves the contract as a template, SignMaster adds a field on every blank, including the signatures and dates. Without a connection, you place the fields yourself after uploading.
Do I need a paid plan for this?
No. Both ways work on SignMaster's Free plan, which includes 3 envelopes a month, and connecting an assistant is included on every plan.
