accuracy for contract intelligence built using Snorkel Flow in under 24 hours


All Data Extracted with No Context Lost

Extract useful data from any tables, cells, and forms linked to all headers, units, or references.


Faster, Lower-cost Development

Use programmatic labeling to develop high-quality AI applications in hours instead of spending weeks or months on expensive hand-labeling.


Rapidly Adaptable

Monitor for changes in the data, and rapidly adapt using built-in error analysis tools. Zoom in on errors to fine-tune training data & models with guided iteration.


High-accuracy Models

Leverage large amounts of labeled and unlabeled data, NLP primitives, and state-of-the-art model architectures to build high-accuracy models.


Flexible Integrations

Easily integrate labeling, training, and analysis pipelines defined over diverse input types–text, PDF, HTML, and more–with downstream applications using APIs or a Python SDK.

Use Cases

Information Extraction Customized for Your Workflow

Case Study

Top US Bank

A top U.S. bank uses Snorkel Flow to quickly build AI applications that classify and extract information from contracts and other legal documents.


The bank estimated that, for a time-sensitive use case, labeling data by hand would take over a month.


With Snorkel Flow, the team produced a AI-powered contract intelligence application that was over 99% accurate in under 24 hours.


The resulting AI application was quickly and easily adapted to new problems.
