Sandstone vs Legora: A Collaborative AI Workspace, or an Operating System for Legal?
Legora is a collaborative AI workspace — shared sessions, research, document review, tabular review, and drafting, layered over Microsoft 365, with a customer base weighted toward European law firms and a growing in-house presence. Sandstone is built around the in-house function: capturing requests as they arrive, routing them with context, and holding the record of how they were resolved.

Frequently asked questions
Yes, and the difference is what's being collaborated on. In Sandstone the unit is the request: legal works it together, with internal comments and drafts separable from what the requester sees, then brings in a business stakeholder or outside counsel deliberately. A shared AI workspace collaborates on the document or session in front of you. Both are useful; only one of them starts when the business asks a question.
Sandstone works across languages, so multi-jurisdictional teams aren't limited to English. If data residency is a hard requirement for you, raise it early and we'll be specific about what we can commit to rather than answer it in the abstract.
Sandstone does basic research, grounded in your own playbooks, precedent, and prior decisions. It isn't built to replace Westlaw or Lexis, and teams with heavy case law and statutory research needs generally run a dedicated research platform alongside it.
Requests, context, and history live in Sandstone whether the work is done internally or sent out, so instructing outside counsel starts from the full record rather than a reconstruction. Replies come back into your systems under a shared team identity.
