Glean
Best AI-powered enterprise workplace search across Slack, GDrive, Jira, and 100+ appsGlean is the leading enterprise AI work assistant — a search-and-answer engine that indexes your company's entire content footprint (Slack, Google Drive, Confluence, Notion, Jira, GitHub, Salesforce, Zendesk, and 100+ other apps) and lets every employee query it like a single brain. Where ChatGPT or Copilot work on the public internet or one Microsoft tenant, Glean grounds answers in your specific company knowledge with permission-aware retrieval — every employee sees only documents they're already authorized to access in the source system, no data leakage. Glean Assistant goes beyond search: it summarizes long docs, drafts responses citing internal sources, generates project briefs from scattered Slack threads, and acts as an onboarding tutor for new hires asking "who owns X?" type questions. The Glean Protect layer adds DLP policies and real-time sensitive-data classification, and Glean Agents lets engineering teams build custom AI workflows with company data as context. Pricing is sales-led (per-employee licenses scale by company size), but the platform commands a premium price because it solves the single most painful enterprise AI problem: getting reliable, sourced answers from internal knowledge that lives across dozens of apps.
