Case Study: Contract lifecycle management software company


A contract lifecycle management (CLM) software provider needed to differentiate themselves from competitors and increase customer acquisition. They also wanted help with one of the key barriers to user adoption: data entry. For users to realize the full benefits of a CLM, they need to key in contract data whenever they upload an executed contract, a hassle for CLM customers everywhere.


Our approach

Our CLM client implemented LegalSifter Engine to extract data automatically from uploaded documents. Today, when their user uploads an executed contract, our Sifters pre-populate data into CLM fields. To double-check the extractions, users receive two types of feedback for each field: the location of the data from the original document and the confidence level of our Sifters for that specific field. Users work on contracts in bulk or on an ongoing basis.


LegalSifter Engine is white-labelled (we removed our brand) within our client's marketing, positioned as an A.I. extraction feature within their software suite and sold at a premium.


LegalSifter Engine helped our client achieve record sales within months. Their customers are raving, reporting significant time savings when entering contracts into the system.

LegalSifter Engine

Our Sifter Library contains hundreds of machine-learning algorithms that use natural language processing to review contract and complex document language.


If you build software, you may communicate with each Sifter through a Docker image on-premise or through a public API. Use cases include information extraction, contract review, and more.

"This feature reduced the average coding time for an NDA from 3 minutes to 30 seconds (I actually timed this), a 10x saving, which is what you'd probably want to see. Overall, I'd say it made a big difference and helped us to focus only on the more complex agreements. We uploaded 72 NDAs in less than an hour.


Overall, I'd say it's a very impressive feature, and really in line with where you want to see AI go. I really like the fact that you can see the portion of the contract from where the A.I. makes its assumptions, so that you can double-check it's confidence level. I can't recall many instances where I was unable to accept a "High" confidence level field. "
