Glean
Enterprise AI search and work assistant that connects all company knowledge sources and answers questions in context.
What it does
Glean is an AI-native enterprise search and work assistant that connects to all a company's knowledge sources - Slack, Google Drive, Confluence, GitHub, Salesforce, Jira, and 100+ others - and provides a single place for employees to search across everything and get AI-generated answers grounded in company-specific information. AI capabilities include deep semantic search that understands the meaning behind queries rather than keyword matching, AI-generated answers that synthesize information from multiple sources with citations, personalized results that surface the most relevant content based on each employee's role and activity patterns, Glean Assistant (a chatbot for company-specific knowledge), and AI-powered knowledge discovery that surfaces relevant content employees didn't know to search for.
Why AI-NATIVE
Glean is AI-native - enterprise knowledge graph search with AI answer synthesis grounded in company-specific data across all connected sources is the core product architecture.
Best for
Mid-market companies use Glean as the AI knowledge layer across their tool stack - employees finding information from any source through one interface and AI answers reducing the time spent hunting through Slack, Confluence, and docs.
Large enterprises use Glean for enterprise AI search - AI grounded in proprietary company knowledge reducing the information retrieval burden at scale and enabling AI-powered work assistance without exposing sensitive data to public LLMs.
Limitations
Glean is most powerful when connected to all major knowledge sources — organizations with only a few tools connected see less comprehensive search and AI answers with more gaps.
Glean is priced for mid-market and enterprise — small teams find the cost disproportionate relative to simpler search tools or AI assistants.
Organizations deeply invested in Microsoft 365 can use Microsoft Copilot for similar enterprise AI search across Office content — Glean's advantage is cross-platform breadth beyond the Microsoft ecosystem.
