What our research says

Glean

Glean is the reference implementation of permission-aware enterprise search, and permissions are the hard part everyone else underestimates. It is also priced so that only companies with a real sprawl problem can justify it.

Pros

  • Permission inheritance from each connected system is done properly, not approximated
  • Answers cite and link the underlying documents rather than paraphrasing them away
  • Connector coverage across the mainstream SaaS estate is broad
  • Commercially solid: about $300M ARR by May 2026 at a $7.2B valuation

Cons

  • No published price anywhere, and contracts start in six figures
  • Value depends entirely on connector coverage of your specific stack
  • Index quality inherits whatever mess exists in the source systems
  • Overlaps increasingly with Microsoft and Google's bundled offerings, which cost nothing extra

OpenParser AI

OpenParser AI is aimed at back-office teams handling contracts and compliance documents rather than casual chat-with-PDF users - the 20+ prebuilt agents for contract review and compliance checks are the actual product, with general Q&A as the entry point. The on-prem option matters for regulated teams but comes with no visible price.

Pros

  • 20+ prebuilt agents for specific document workflows, not just open-ended chat
  • Answers are cited back to source documents
  • Clear per-seat price ($30/user/month) with a no-card 15-day trial

Cons

  • On-prem pricing is entirely custom-quoted with no ballpark given
  • No API availability mentioned anywhere on the site
  • Per-seat pricing can get expensive for larger document teams

Which one fits

Choose Glean if you need

  • Organisations above roughly 500 people whose knowledge is scattered across a dozen SaaS tools
  • Regulated or security-conscious buyers who need source-system permissions honoured exactly
  • Teams building internal agents that need governed access to company context

Choose OpenParser AI if you need

  • Legal, procurement, and compliance teams reviewing documents at volume
  • Organizations needing cited, source-linked answers rather than free-form chat
