Where DocIQ Sphere differs

Document editing with tracked changes

CoCounsel is primarily a research and review tool. It drafts outputs but does not produce native Word tracked changes in existing documents. Sphere edits documents: natural language instructions produce standard Accept/Reject revision marks in .docx files.

  • Native OOXML tracked changes
  • Paragraph-level precision editing
  • Edit both source and output documents in-app

Swiss and EU law specialization

CoCounsel's Westlaw foundation is strongest in common law jurisdictions (US, UK, Australia). Sphere's 6 databases specialize in Swiss and EU law: Fedlex, BGE, EUR-Lex, CJEU, ECHR, and Commentary. For Swiss/EU focused practices, Sphere's research sources are more directly relevant.

  • Fedlex: Swiss federal statutes
  • BGE: Swiss Federal Supreme Court decisions
  • EUR-Lex + CJEU: EU regulations and case law

Integrated clause bank and data rooms

CoCounsel provides research and drafting. Sphere additionally includes jurisdiction-tagged clause banks with hybrid search, virtual data rooms with audit trails, and a knowledge base that indexes 15+ document formats. More tools in one platform.

CH/EU deployment and data sovereignty

CoCounsel is primarily available in the US, with UK expansion planned for H1 2026. Sphere offers managed cloud in CH/EU, on-premise, and air-gapped deployment. For Swiss and EU organizations with data sovereignty requirements, Sphere is deployable today.

  • Available now in CH/EU
  • On-premise and air-gapped options
  • Professional secrecy compliance
