Glean
- +Best-in-class unified, permission-enforced index across many apps with citation-grounded answers
- +Genuinely model-agnostic and open: MCP host plus server, bring-your-own model, and on-prem deployment
- +One governed platform spanning search, assistant, and agents with built-in certification and monitoring
- -Opaque, expensive pricing with high seat minimums and add-on fees; reported fully-loaded deployments run into the hundreds of thousands
- -The autonomous-agents marketing outpaces demonstrated autonomy; in practice agents are supervised
Notion AI
- +Tightly integrated into a workspace people already use, so AI has rich, native context
- +Multi-model access with automatic routing means strong models without managing them
- +Custom Agents extend from assist-me to doing recurring work for the team without code
- -Real AI value is gated behind the Business/Enterprise tier and, for agents, a new credit-based add-on
- -Quality and context are bounded by what is in your Notion workspace and connectors; weak for work outside Notion
