Choose ChatGPT if
Knowledge workers, students and teams who want one general-purpose assistant with wide capabilities.
- Broadest feature set and app ecosystem
- Strong free tier
- Desktop and mobile apps are polished
Look elsewhere if: Workflows that need deterministic outputs or on-premise deployment; use APIs with structured outputs instead.
Choose Glean if
Large companies with knowledge spread across dozens of SaaS tools that need permission-safe AI search and assistants.
- Among the most mature permission-aware enterprise search products
- Very broad connector library including code and ticketing tools
- Model-agnostic, so companies are not tied to one AI vendor
Look elsewhere if: Small teams or firms already standardized on one suite's AI (Microsoft 365 Copilot, ChatGPT Enterprise or Notion AI are simpler).
