What ContraxSuite is
ContraxSuite is an open-source legal document and contract analytics platform made by ContraxSuite, founded in 2013, with headquarters in Chicago, Detroit, Houston, and Boston. It uses LexNLP, a machine-learning library, and pre-trained analytics models to examine legal material. The platform can identify, organize, deduplicate, and relate documents; extract terms; locate clauses; and visualize or export results. Users can apply ready-made analysis, train clause models without development, and customize the software. Document ingestion and OCR cover Word, WordPerfect, PDF, and HTML, with the system described as able to process millions of files per day. Listed sources include Google Apps, Office 365, Exchange, iManage, Dropbox, and Salesforce; automated uploads can use HTTPS POST or SFTP. ContraxSuite is available through web, Linux, API, and self-hosted options, with hosted or self-hosted deployment. Hosted instances can use Microsoft Azure or Amazon Web Services and be placed in selected regions or regulatory jurisdictions. Managed services include deployment, configuration, SLA-driven support, and training. Licensing is available under AGPL or a purchased non-AGPL license.
