Glean Review: Features, Pricing & Alternatives

What is Glean?

Glean is an enterprise AI platform that connects to the apps a company already uses, such as Slack, Google Drive, Jira, Confluence, SharePoint, GitHub and Salesforce, and lets employees search, ask questions and run agents across all of them. Answers come with citations, and the system respects each source’s permissions, so people only see content they are already allowed to open.

Glean Technologies was founded in 2019 by Arvind Jain and is based in Palo Alto, California. It came out of stealth in September 2021 as a workplace search tool. It announced an agent platform in February 2025 and made it generally available in May 2025. In June 2025 it raised a $150 million Series F at a $7.2 billion valuation, and in May 2026 it said annual recurring revenue had passed $300 million.

What sets Glean apart is its focus on company context rather than on a single chat model. It offers more than 250 connectors, a model hub that it says covers 40+ LLMs with automatic routing, an MCP server so tools like Claude Code and Cursor can query company knowledge, and Glean Protect for governance. The trade-off is that it is sold only to organisations through sales, with no self-serve plan.

Glean pricing (October 2026)

Glean does not publish prices on its website; cost depends on the number of users, the products and options chosen, and the contract, so ask Glean sales for a quote. Third-party price estimates online are not official.

Glean vs alternatives

Microsoft Copilot is the natural rival for Microsoft 365 companies, since it works inside Word, Outlook and Teams and draws mainly on Microsoft Graph data. Gemini plays the same role for Google Workspace. Glean’s advantage is neutrality: it indexes many vendors’ apps equally and adds a dedicated search experience and agent builder on top.

ChatGPT and Claude business plans can connect to company apps too, and they are stronger general-purpose assistants, but enterprise search and permission-aware ranking are Glean’s core product. For smaller teams whose knowledge lives mostly in one workspace, Notion AI is a cheaper, simpler option. See all best AI productivity tools.
