99 Data Rooms review
The only room on this list that publishes a full price ladder in pounds, starts free and exposes a logged, read only MCP endpoint so an AI assistant can work inside the room under permission controls. It also ships an AI legal drafter and contract management, which most rooms at any price still leave to a separate tool.
What it does well
- +Agent access over MCP is read only by default, revocable and fully logged, so a language model can answer diligence questions without a human exporting files first.
- +The AI legal drafter produces NDAs, term sheets and side letters in PDF or Word inside the room, and contract management tracks the signed version alongside the folder it came from.
- +Multi party Q&A runs inside the room, so buyers, advisers and counsel raise questions against a specific document and answers stay attached to it with a full history.
- +Page by page viewer analytics, verified email codes, passcodes, NDA gating, expiry, max views and one click revoke are all on the published plans rather than quoted as extras.
Where it falls short
- −It is a young platform, so it does not yet carry the SOC 2 Type II or ISO 27001 reports that bank security reviews ask for.
- −Bidder segmentation for large auctions with a dozen separate buyer teams is lighter than the enterprise rooms built for that job.
