  • Agentic search and research layer
  • Private VPC and single-tenant deployment options
  • Founding team pioneered RAG research
  • Pricing is enterprise sales-led, not transparent
  • Aimed at technical/regulated industries, not consumers
  • Requires data and knowledge-base setup to shine

Glean

Permission-aware knowledge graph that no-code agents can act on, not just search across your enterprise apps.

  • Indexes 100+ enterprise apps
  • Enforces each user's existing permissions
  • No-code custom agents
  • Strong onboarding/knowledge ROI
  • Opaque, sales-only enterprise pricing
  • High seat minimums (~100 users)
  • IT-heavy to deploy and maintain
  • Limited to supported connectors
