Papermark
Secure, open-source data rooms and document sharing with AI redaction and page-by-page analytics
Papermark is a secure data room and document-sharing platform built for M&A, fundraising, due diligence, and other deal-sensitive document sharing. Every shared link gives page-by-page analytics — who viewed which page, for how long, and which pages closed the deal versus lost the room. Data rooms ship with SSO, granular permissions, dynamic watermarking, NDA gating, audit logs, IP allow-listing, and end-to-end encryption, with an option to self-host on your own infrastructure (Papermark is open source on GitHub). Its AI redaction feature scans every page for personal data (7 PII categories) plus custom deal-specific terms you define, lets you review each detection, and burns the accepted redactions permanently into a new version — no exporting to Acrobat and no black boxes a bidder could copy underneath.

FAQ
What is Papermark?
A secure data room and document-sharing platform for M&A, fundraising, and due diligence, with page-by-page analytics on every shared document.
Is Papermark open source?
Yes — it's open source on GitHub, with an option to self-host on your own infrastructure instead of using Papermark's hosted version.
What is AI redaction?
It scans every page for personal data (7 PII categories) and custom terms you define, lets you review each detection, and permanently burns the accepted redactions into a new version of the document.
Where it holds up
- Page-by-page view analytics show exactly which pages held attention and which lost the deal
- Open source with a self-hosting option, unusual for a data-room product in this price range
- AI redaction scans for PII and custom deal terms, then burns accepted redactions permanently into the document
Where it falls short
- Full data-room features (NDA gating, watermarking, unlimited storage) require the $119/mo Data Rooms plan
- Free plan is capped at 50 links and 50 documents, tight for an active deal
