Cerulean is a web platform for bundles, hearings, and evidence in high-value litigation and arbitration.
What Cerulean is
Cerulean is a web platform for bundles, hearings, and evidence in high-value litigation and arbitration. Cerulean Systems Ltd says it is intended for counsel and tribunals and is in private preview for selected chambers and tribunals. Its three-zone reading workspace is designed for hearing days and bundles containing tens of thousands of documents. Users can ask plain-English questions about a matter bundle and receive paragraph-grounded answers with citations linked to source passages. Presentation mode sends pages, paragraphs, or excerpts to the tribunal with a keystroke. Live transcripts are threaded into the bundle, while reading itineraries can remain private to counsel or be shared in the tribunal’s common record. It supports exhibit management and evidence annotation, with integrations listed for Microsoft Word, SharePoint, and NetDocuments; connectors are provisioned per matter. Cerulean says each matter is isolated in its own tenant, client documents and answers are not used for model training, and hosting is in UK data centres, with region-locking available on request. Its security page lists SOC 2 Type II as maintained, ISO 27001 and ISO 42001 as certified, and UK and EU GDPR compliance. Pricing is on request.
