Cerulean is an AI-native bundle, hearing and evidence platform for high-value litigation and arbitration. Cerulean Systems Ltd says it is designed for counsel and tribunals, and is currently in private preview for selected chambers and tribunals. Its three-zone reading workspace is intended for hearing days and bundles containing tens of thousands of documents. Users can ask questions about a matter bundle in plain English and get paragraph-grounded answers with citations linking to source passages. In presentation mode, pages, paragraphs or excerpts can be sent to the tribunal with a single 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. The site lists integrations with Microsoft Word, SharePoint and NetDocuments, with connectors provisioned for each matter. Cerulean says each matter is isolated in its own tenant, client documents are not used to train models, answers are never retained for training, and its service is hosted in UK data centres, with region-locking available on request. Listed security measures include SAML single sign-on, enforced multi-factor authentication, matter-scoped roles, IP allow-listing, cryptographically integrity-protected action logs and verified erasure across live stores, caches and derived indexes. The product is available on the web; pricing is on request.
Who it is for
