How it Works
A graphic depicting the various stages of the process by which our AI understands documents

1. Read Text & Formatting

First, we pull the text contained in a contract, including font size, styles like bold or italics, indentation, position on page, and more. All of these are signals for our AI.

2. Understand Structure

Our system then identifies headers & footers, clauses & sub-clauses, signature blocks, and recognizes multiple contracts and attachments within the same PDF.

3. Classify & Extract

Finally, the system uses these learnings to classify contract language into the clauses it represents, the type of contract it is, and extract parties, dates, termination periods, governing laws, and over 120 more fields.

Our homegrown NLP platform allows us to quickly create new models for bespoke use cases—just as we did for UiPath, which saw up to 94+% model quality in just one week.

Lexion's state-of-the-art AI and robust technical stack can adapt quickly to new sets of documents with little to no human input. For UiPath—and for companies like yours—that means quick insight and understanding across enormous collections of contracts.

Lexion's ability to scan and accurate extract fields from signed contracts (like party names, title, terms, and termination, etc.) is absolutely the best in class. The AI is critical to quickly organize a large volume of contracts with a minimal human touch and quickly find what you are looking for.
