Summarize contract redlines instantly

River's Contract Redline Summary Generator analyzes two contract versions and creates a comprehensive summary of all changes. You paste the original and revised contracts. The AI identifies every addition, deletion, and modification, then generates an organized summary categorizing changes by importance and impact. Within minutes, you have a detailed change summary ready to share with clients or stakeholders. Perfect for in-house counsel reviewing vendor redlines, attorneys negotiating contracts, and deal teams tracking negotiation progress.

Unlike simple track changes that show every edit visually, we provide a written summary explaining what changed and why it matters. The AI categorizes changes into material business terms, legal provisions, administrative updates, and minor edits. You get summaries that help decision-makers understand substantive changes without reviewing entire contracts word-by-word. Each summary identifies new obligations, deleted protections, modified deadlines, and changed liability provisions.

This tool is perfect for in-house counsel managing multiple contract negotiations, attorneys tracking deal terms through revision cycles, paralegals summarizing changes for attorney review, and business teams needing executive summaries of contract modifications. Use it when receiving redlined contracts back from counterparties. Use it to brief stakeholders on negotiation progress. Great for maintaining clear records of what changed between contract versions. The AI creates organized summaries that save hours of manual comparison.

Why Contract Change Summaries Matter

Tracking contract changes during negotiations prevents missed modifications and ensures nothing harmful sneaks through. Counterparties sometimes make substantive changes while claiming they're 'just minor clarifications.' A clean, professional summary of all changes protects you by forcing systematic review of every modification. Business teams may not understand legal implications of seemingly minor language changes. Change summaries translate contract edits into business impacts that non-lawyers can evaluate.

Material changes need more scrutiny than administrative updates. Not all contract changes matter equally. Changing a deadline from 30 days to 15 days is material. Fixing a typo isn't. Good change summaries categorize edits by importance so reviewers can focus attention appropriately. Material changes affecting price, liability, performance obligations, or termination rights require careful business and legal review. Administrative changes like correcting addresses or adding section numbers can be accepted quickly. Categorization enables efficient review.

Change summaries create negotiation records. When contracts go through five rounds of revisions, it's easy to lose track of what each side agreed to and when. Summaries of each revision create a negotiation history showing evolution of terms. This helps if disputes arise later about what was agreed. It also prevents re-arguing settled points. If you agreed to a provision in version 3, having that documented in the version 3 summary prevents the other side from trying to change it again in version 5.

Frequently Asked Questions

Does this replace attorney review of changes?

No. This tool creates a summary to make review more efficient, but attorneys must still review substantive changes carefully. The AI identifies changes and categorizes their apparent importance, but attorney judgment determines what's truly material for your specific situation. Use the summary to organize and prioritize your review, not to substitute for it. Some seemingly minor language changes can have major legal implications. Always have an attorney review material contract modifications.

What if the contracts are very different?

The tool works best when comparing similar contract versions with tracked changes during negotiations. If contracts are substantially different (completely different structures or major rewrites), comparison becomes less meaningful because almost everything is 'changed.' For major rewrites, review the new version as if it's a new contract rather than trying to compare to the prior version. The tool is designed for iterative negotiations where contracts evolve through revisions, not for comparing completely different agreements.

Can this compare contracts in Word track changes format?

Copy the clean versions (with all changes accepted) rather than pasting tracked changes markup. The AI needs to see the actual text of each version, not the markup codes. If you have Word track changes, accept all changes for version 1, copy that text, then paste. Then accept the changes for version 2, copy that text, and paste after the separator. The AI will then identify what changed between the clean versions.

How do I categorize which changes to push back on?

Focus on changes affecting price, liability, performance obligations, termination rights, and legal protections. Changes that increase your obligations, decrease your protections, shorten your deadlines, or expand your liability are candidates for pushback. Changes that are neutral, administrative, or favorable can generally be accepted. Your business team should evaluate commercial terms. Your attorney should evaluate legal provisions. The summary helps organize changes for each audience to review efficiently.

Should I create summaries for every contract revision?

Yes, for important contracts during active negotiations. Creating a summary for each version (Version 1 to Version 2, Version 2 to Version 3, etc.) documents the negotiation progression and ensures nothing gets lost between rounds. For minor contracts or single-round negotiations, one summary might suffice. For complex deals with multiple revision cycles, systematic summaries prevent confusion and create useful records. The time spent on summaries is recovered through more efficient review and better negotiation outcomes.
