Summary

A recent independent benchmark conducted in April 2026 evaluated the performance of AI-powered contract review platforms against a human attorney, specifically comparing Ivo, Claude for Word (Opus 4.6), and a Special Counsel from an AmLaw 25 firm. The study involved reviewing 19 real, anonymized contracts, including NDAs, MSAs, and DPAs. Outputs were blind-scored by three technology transaction attorneys across five criteria: issue spotting, surgical redlining, formatting retention, judgment, and comments. Ivo achieved a score of 4.52 out of 10, closely trailing the human attorney's 4.56, while Claude for Word scored significantly lower at 3.50. The findings indicate that purpose-built legal AI systems like Ivo outperform general-purpose LLMs in specialized legal tasks, particularly in surgical redlining and legal judgment, and can complete reviews in minutes compared to hours for humans.

Key takeaway

For legal teams evaluating AI solutions for contract review, you should prioritize purpose-built legal AI platforms over general-purpose LLMs. While general AI shows limitations in critical areas like surgical redlining and legal judgment, specialized systems like Ivo demonstrate near-human accuracy and significantly reduce review times, allowing your team to focus on strategic negotiations and client outcomes rather than manual, repetitive tasks.
