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

Nouswise

Nouswise is positioned for teams that want answers grounded strictly in their own documents rather than the open web, with on-premises deployment and a dedicated-region option that matter to institutional buyers. The free Starter plan, 100 sources with daily caps on generated reports and recaps, is enough to evaluate the grounding before paying. The API and MCP tools make it usable as infrastructure rather than only a chat window, but the paid tiers doubled since our last read, to $19.99 and $49.99.

Pros

Free tier covers unlimited projects and 100 sources, enough for a real evaluation
Answers are restricted to provided sources, reducing hallucination risk
On-premises and dedicated-region deployment for compliance-bound buyers
API and MCP tools for embedding into other software

Cons

Unlimited sources only unlock at the $49.99/month Pro tier
Every tier below Enterprise caps generated activities and recaps per day
Company address and country are not disclosed on the site
Agentic cross-checking across sources can add latency versus a single-model answer
