How ThoughtRiver works

Our pre-screening technology is underpinned by Lexible, the universal contract knowledge tree and a sophisticated Natural Language Processing (NLP) engine.

Our pre-screening technology works by first deploying a sophisticated language processing (NLP) engine developed in collaboration with Cambridge University. This allows us to understand the meaning of the words within an agreement. We can then ask and answer thousands of questions according to our Lexible framework to build a detailed picture of the obligations and rights within the agreement. All of this data is then summarized into clear, actionable advice.

What is Lexible?

The Lexible contract description framework is an ontology of meaning-based properties that together encapsulate the complex legal logic and relationships present in an agreement. It includes thousands of individual questions that together build a granular picture of obligations and rights within a document. Lexible is developed both by ThoughtRiver’s lawyers and our partners who are domain experts.

What is lexible

How does Lexible work?

Each property on Lexible is expressed as a question (e.g. Does the counterparty have a right to assign this contract to anyone?) ThoughtRiver’s pre-screening tool automatically determines which properties are relevant for your contract type and answers all associated questions for you. It then tells you how risky those positions are against your playbook.

Why do it this way?

Our Lawyers believe the best way to approach automated contract review is a combination of valuable legal intelligence coupled with advanced machine learning capabilities. By doing this we can accurately and consistently simulate the human contract review process. Aligning this with the universal Lexible framework allows our tool to access a larger amount of training data and make logical connections between clauses, increasing our accuracy while decreasing time to value for our users.

Lexible Partners

Any lawyer or commercial domain expert has an opportunity to extend their own area of Lexible and leverage its platform capabilities to deliver niche contract review services to clients. We have Lexible partners providing services to clients across several verticals already, but are always happy to welcome more to our community.


Use Cases

We support two core use cases. Pre-screening which is typically undertaken in the context of reviewing unsigned contracts, and exploration which is about extracting and analyzing data from a volume of signed contracts.  Both use cases have many practical applications.
