Contract redlining software increases review efficiency by automating the first pass, while also maintaining accurate records of what was agreed to when. Some redlining tools also perform blacklining, enabling lawyers to compare drafts without reading through both.

Trusted by fast-growing teams
Fast, accurate redlines without implementing software
Crosby builds custom AI agents, trained on market data and your legal preferences, to perform contract redlines. A licensed attorney stays in the loop, so you receive the human judgment redlining tools alone can’t provide.
No software implementation or maintenance
Crosby builds a custom AI agent based on your playbook, and its team of barred attorneys applies deal context to contracts. When using standalone, self-serve contract redlining software, your organization is responsible for maintaining the data the tool runs on and ensuring human review.
Redlines ready to send
Crosby delivers a redlined contract that can be sent to the counterparty without further review from your team. Contract redlining software leaves you to reject or accept edits.
A barred attorney in the loop
Contract redlining software can’t provide human judgment. Crosby pairs the speed of AI review and the nuance of customized agents with the expertise of a supervising lawyer.
Why redlining slows deals down
Slow redlining stalls deal momentum, and unsynced, manual work is often the root cause.
Version confusion and missed edits
When redlining happens across email and shared drives, finalizing edits can take weeks or months due to poor version control, leading to redundant reviews.
Repeated edits
Standard commercial contracts often contain the same language, so teams make similar types of edits to each agreement. Manual, repetitive edits are a time sink that software can absorb.
Inconsistent positions across contracts
In manual contract redlining workflows, lawyers compare agreement language to playbooks by hand, which takes time and focus away from other tasks. In a time crunch, teams can skim an important detail or apply a position that deviates from the norm, exposing the organization to risk.

Contract redlining FAQs
What are the benefits of using contract redlining software?
How does AI improve contract redlining software?
AI can capture market data and an organization’s positions, enabling it to compare contracts against norms and redline nonstandard language. Lawyers start from a contract with flagged risks and deviations, so they can spend their time checking for accuracy and applying human judgment instead of manually comparing terms against a playbook.
How do you choose the best contract redlining software?
The best contract redlining software is the one that fits your use case and clears your biggest legal review bottlenecks. The software should also integrate with your existing tech stack to minimize tool toggling.
Can legal redline software fit into a CLM platform?
Some contract lifecycle management (CLM) platforms offer built-in redlining. Others integrate with external redlining tools. In both cases, the CLM stores the contract to be redlined. Once the parties agree to changes, the CLM pushes the contract through the approval and signature workflows and saves the final version.
