We analyzed the top 15 contract review software solutions and compared them with LLMs to see how they might help simplify the contract review process. Our research identified key features and 5 use cases that show how these tools can overcome the challenges of manually reviewing contracts—a task that is often both time-consuming and complex.
*The number of employees information has been gathered from LinkedIn.
**The total funding amount information has been gathered from Crunchbase.
LLMs are also widely used for contract review. You can compare LLMs with legal AI software or see how different LLMs perform below:
Performance of LLMs on legal applications
Although contract review software offers many conveniences in terms of use, LLMs also show an undeniable performance in legal applications.
*The models were selected based on the overall accuracy scores they achieved on the LegalBench benchmark.
Models such as Claude 3.5 Haiku, o3 Mini, and DeepSeek R1 failed to reach the top 15 and were therefore not included.

LLMs vs contract review software
While LLMs are widely used for contract review, using generic LLMs can raise confidentiality concerns since data might be shared with third parties.
In contrast, contract review software often employs proprietary legal LLMs, which tend to achieve higher accuracy and ensure that sensitive data remains secure.
Additionally, these software solutions offer user-friendly interfaces, automation features, and collaboration tools that enable teams to work together efficiently, making them a practical choice for secure and effective contract analysis.
It is also important to note that future innovations by LLM providers in these specific areas will undoubtedly influence this comparison.
