AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.

A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.

Saige Assist brings contract AI into every step — review, drafting and analysis — built on your own contract portfolio rather than a generic LLM, with governed controls on how the AI works.
Manage intake, approvals, drafting, negotiation and e-signature in one workflow, replacing fragmented email-and-spreadsheet processes across legal, procurement and revenue teams.
Search, organize and summarize every agreement, with AI summarization that pulls key terms and obligations out of long documents, plus obligation, renewal and rebate tracking.
Native connectors for Salesforce, Workday, DocuSign, Adobe Sign, Bullhorn and Microsoft, plus 1,200+ apps via Workato, an open REST API and webhooks.
