Glean vs OpenParser AI

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
