The AI data room built for M&A.

Sifrsys applies permission checks inside the database query. When a buyer's analyst asks the AI a question, it retrieves information only from documents within their access. Management-side documents, other buyer groups' materials and anything outside the analyst's access are excluded. Answers cite source documents, with page or cell references where available, and citations open the source.

Your documents, queries and AI conversations are never used to train models, and our AI providers retain nothing. Chat history does persist inside your room — deliberately. A question asked during diligence is part of the record, and an audit trail with the questions removed is not an audit trail. You can see every exchange, and so can your auditor.

Established providers offer AI features too, so compare the specifics. Check whether an answer cites the exact page or cell and opens it, whether the AI is limited to what each reader may see, how the price changes with pages and users, and whether you can start without a sales call. In Sifrsys, answers cite source documents with page or cell references where available, and citations open the source. Retrieval is fenced by each participant's permissions, plans are flat and published with no per-page fees, and you can create a room yourself on the free plan.

Yes, on the Data Rooms plan and above. Sifrsys supports 5 permission levels (none, fence, view, download, full) with group, folder, and document-level overrides. Each buyer group sees only what you've authorized. The AI is fenced by the same boundaries — it cannot reference documents outside a participant's access level, even if they exist in the same room.

You can create a data room, upload documents, and invite participants in minutes. Documents are automatically parsed and indexed for AI retrieval. Participants get passwordless magic link access — no account creation needed. Smart Sort AI auto-categorizes documents into standard due diligence folders.
