Three free, in-browser tools from Gavel: a legal document automation savings calculator, an AI contract review time calculator and a contract clause checker. None of them requires an account, and nothing you type leaves your browser. Defaults come from Gavel's 50-firm drafting study and published customer case studies, and you can change every number.
For document automation
Enter how many estate plans, divorce packets, formations, employment agreements and engagement letters your firm drafts each month. The calculator returns hours and dollars saved per month and per year, using before-and-after drafting times measured in Gavel's study of 50 firms.
Open the savings calculatorFor contract review
Enter contracts reviewed per month, hours per first-pass review and your hourly rate, then set the percentage of review time an AI first pass removes. The slider starts at 50 percent, the middle of what Gavel Exec customers have reported in case studies.
Open the review calculatorFor a quick contract read
Paste a contract clause and the checker identifies which of 17 common clause types it is, then flags the terms lawyers most often negotiate: a limitation of liability with no cap or that protects only one party, a one-way indemnity, an auto-renewal with no notice deadline, a termination right with no cure period, and vague standards such as "best efforts." Each clause type links to Gavel's clause library.
Open the clause checkerEach tool runs entirely in your browser. There is no sign-up, no file upload and no request to a server; the page loads once and the arithmetic happens on your device, so a contract pasted into the clause checker stays on your screen.
The calculators are prefilled with published numbers rather than marketing estimates. The drafting times come from Gavel's study of 50 corporate, estate planning and family law firms, which measured time per document before and after automation, and the contract review reductions come from named customer case studies, including a regulated financial services firm (40 to 60 percent per contract) and MIA Contract Lawyers (about 15 hours to 5 per contract). Every default is editable.
The clause checker uses pattern matching, not a language model. It is a fast first read that tells you what is present and what to look at, and it does not replace a lawyer's review or Gavel Exec's AI redlining inside Microsoft Word.
Yes. The three tools on this page need no account, no credit card and no email address, and there is no usage limit. They are built and maintained by Gavel, the legal document automation company behind Gavel Workflows and Gavel Exec.
The checker runs in your browser and sends nothing to Gavel or anyone else; the text never leaves your device. Follow your firm's confidentiality policy as you would for any software, and close the tab when you are done.
The document automation defaults come from Gavel's study of 50 law firms, which measured drafting time before and after automation for estate planning, divorce, formation and employment documents. The contract review defaults come from published Gavel Exec customer case studies. Every default can be changed.
