Document Sharing And Access Control

via “access control and audit logging for sensitive documents”

Hi HN,I built an open-source AI agent that has already indexed and can search the entire Epstein files, roughly 100M words of publicly released documents.The goal was simple: make a large, messy corpus of PDFs and text files immediately searchable in a precise way, without relying on keyword search

Unique: Implements document-level access control with comprehensive audit logging specifically for investigative workflows, likely with chain-of-custody tracking for legal admissibility

vs others: More rigorous than simple user authentication because it tracks every access and enforces fine-grained permissions, meeting compliance requirements for sensitive document handling

via “document access control and permission management”

Unique: Implements role-based access control with real-time permission enforcement and audit logging, enabling secure document sharing without requiring external identity management systems

vs others: More granular than simple file sharing and more integrated than managing permissions via email, but less sophisticated than enterprise identity providers like Okta or Azure AD for complex organizational hierarchies

via “granular access control and permissions”

via “multi-user permission management and access control”

Unique: Implements role-based access control with granular permission levels (view, comment, edit, admin) and access logging; supports time-limited permissions and public sharing with optional protection rather than simple all-or-nothing sharing

vs others: More flexible than Google Docs for permission management because it supports comment-only access; better than email-based sharing because permissions are centrally managed and can be revoked instantly

via “collaborative knowledge workspace with shared document collections”

Unique: unknown — no architectural details on collaboration patterns (CRDT, operational transformation), permission model, or audit logging infrastructure

vs others: Positions as integrated collaboration vs. standalone document management, but lacks transparency vs. specialized tools (Notion, Confluence) on real-time collaboration or feature depth
