What our research says

Capitol.ai

Built around the part enterprise buyers actually argue about — lineage, approvals and an audit trail on every generated artifact — rather than chat quality. The catch is that it is a procurement-shaped purchase: no price, no trial, and value depends on connecting your governed data sources first.

Pros

  • Outputs carry sources, steps, approvals and review by design
  • Model-agnostic across commercial and open-weight models
  • Search, transcription, spreadsheets, decks and publishing are built in
  • Runs against data where it already lives instead of re-uploading files

Cons

  • No public pricing, trial or self-serve entry point
  • No documented public API on the marketing site
  • Governance value is unverifiable without a pilot

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

Which one fits

Choose Capitol.ai if you need

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
