Contract redlining software that returns a first pass redline in Word
The positions your team would normally mark up by hand, proposed for you as tracked changes and comments in Microsoft Word. Accept, change, or reject the markup.
Test BlackBoiler on a recurring agreement your team is already familiar with.
The manual gap
Stop rebuilding contract markup your team has already worked out
A new agreement should not mean starting the redline from scratch. Yet reviewers still search previous contracts, check the playbook, compare familiar clauses, and recreate edits the legal team has made before.
Your standards are already set. Yet on every agreement, a skilled reviewer still has to find them, compare them, decide what applies, and rebuild the markup by hand.
Your previous redlines and playbook inform the proposed edits
BlackBoiler uses your approved language, previous redlines, examples, and playbook guidance to inform the first pass markup. The redline is grounded in evidence of how your team already reviews contracts, so the proposed markup has context from the positions and examples you already use.

Approved language

Give BlackBoiler evidence of what a good result looks like for your organization.
Pick one agreement your team has redlined before and see how close the first pass lands.
Choose a recurring agreement your team has reviewed before. Run it through BlackBoiler and compare the first pass redline with the edits your team would normally make.
Use the result to answer the questions that matter.
Did BlackBoiler identify the contract language your playbook covers?
Do the proposed edits reflect the positions your team uses?
How much of the first pass markup is already there when you begin your review?
What still requires your legal judgment?
Contract Redlining FAQs
What happens when the contract language differs from our examples?
BlackBoiler assesses the contract language against the outcome defined in your playbook and the customer evidence available. The proposed edit is checked against the intended outcome and relevant examples before your lawyer reviews the tracked changes. Your lawyer decides whether the proposed markup is appropriate for the agreement.
What do I need to provide for BlackBoiler to redline against our positions?
Use the materials your team already relies on when reviewing contracts. These should include previous redlines (in any format), approved language, examples, and any existing playbook guidance. BlackBoiler uses this customer-specific evidence to build your playbook and inform the first pass markup.

About BlackBoiler
Contract review from a company that has done this since 2019
BlackBoiler has focused on automated contract redlining since 2019, before the current wave of legal AI. The technology is patented and purpose-built for one job: carrying the positions a legal team has already developed into first pass tracked changes in Microsoft Word, with the output checked before it reaches the lawyer and again during review.
Built on your standards, not a general model
Your playbook, previous redlines, approved language, and examples inform the positions BlackBoiler applies. The review starts from contract knowledge your team has already built, rather than a general-purpose model working from a prompt. The reviewer decides what to accept, change or reject.
Put your approved positions to work on the next recurring agreement
Test BlackBoiler on contract language your team already knows and judge the first pass against the markup you would have created by hand.
