Why BlackBoiler

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. BlackBoiler gives you the first-pass markup so you can spend your review on the language that needs fresh legal judgment.

In Microsoft Word

Review the proposed contract markup directly in Word

BlackBoiler returns a first-pass redline with tracked changes and comments already applied to the agreement. Review the proposed edits in the document, make any changes that require your judgment, and decide what moves forward.

✎

Tracked changes

See the proposed contract revisions in Word rather than working from a separate summary.

💬

Comments

Review comments alongside the relevant contract language.

✓

Your review

Accept, change, reject, or escalate the proposed markup before anything moves to negotiation.

Try It Yourself

See how BlackBoiler redlines one of your own contracts

Choose a recurring agreement your team already knows well. Run it through BlackBoiler and compare the first-pass markup against the edits you would normally make yourself.

You can judge the product on the questions that matter:

  • ? Did it 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 needs your legal judgment?

FAQ

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.
