Capitol.ai vs Glean

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
