Glean Review (2026): Pricing, Features & Honest Verdict

TLDR

Glean is an enterprise Work AI platform combining permissions-aware search, an AI assistant, and custom agents across 100+ company apps. It is the most polished option in the category, but locked behind opaque sales quotes. Best for: mid-to-large enterprises. Price: From ~$50/user/mo, no free plan. Rating: 8.2/10.

What is Glean?

Glean is an enterprise “Work AI” platform that ties together three things employees usually juggle separately: company-wide search, a personalized AI assistant, and custom AI agents. It connects to more than 100 applications, Slack, Google Workspace, Jira, Confluence, Salesforce, GitHub and the rest, indexes what your company knows, and then answers questions while enforcing each source’s existing permissions in real time. The result is a single search bar (and chatbot) that actually understands your org.

The company, Glean Technologies, was founded in 2019 by Arvind Jain, a former Google search engineer who also co-founded Rubrik. It has scaled fast: more than $100M in annual recurring revenue within three years of launch, and a $150M Series F in June 2025 that valued it at $7.2 billion. Customers include Booking.com, Instacart, Webflow and Databricks. This is not an experiment, it is one of the defining enterprise AI companies of the moment.

What Are Glean’s Key Features?

Permissions-aware enterprise search

The core of Glean is search that respects access controls. It indexes content across all your connected apps but only ever shows a given user what they already have permission to see, enforced at query time. That single detail is why security teams sign off on it where simpler tools fail.

Personalized AI assistant

On top of search sits an assistant that can summarize documents, draft content, and answer natural-language questions grounded in your company’s real data, not the open internet. Because it knows your role and your team, the answers are contextual rather than generic.

No-code AI agents

Glean’s agent platform lets teams build and deploy automated workflows, onboarding helpers, support triage, research assistants, without writing code. Agents can read across the same connected sources and take actions, extending Glean from “find things” to “do things.”

100+ connectors

Out of the box Glean integrates with the apps enterprises actually run on. That breadth is the moat: the more of your stack it touches, the more useful the unified search and assistant become, and the harder it is to replace.

How Much Does Glean Cost?

Glean does not publish pricing, every contract is custom-quoted through sales, often after a paid proof-of-concept. Industry sources consistently peg the starting point at roughly $50 per user per month with a ~100-seat minimum (about $60,000/year), and AI features are frequently an additional ~$15/user/month on top of base licensing. Large deployments routinely run $240,000/year and up once integrations, indexing and support are factored in, and renewals can climb 30-50% at scale.

For comparison, Microsoft 365 Copilot runs about $30/user/month on top of your M365 license, Guru is around $25/user/month, and GoSearch starts near $20-25/user/month with an actual free tier. Glean is the premium, opaque option in a field where competitors are getting more transparent.

Who Is Glean Best For?

Use Glean if you run a mid-to-large organization (100+ employees) with knowledge scattered across dozens of SaaS tools, and you want one secure, permissions-aware place to search it all and layer AI assistants and agents on top. If you have the budget and a person to administer it, the time savings are real, Glean cites up to 110 hours saved per user per year.

Skip Glean if you are a solo founder, a small team, or anyone who needs transparent self-serve pricing. The 100-seat minimum, six-figure total cost, and sales-gated access make it a non-starter below enterprise scale, and cheaper, more transparent tools will cover smaller use cases just fine.

What Are the Best Glean Alternatives?

Microsoft 365 Copilot

At roughly $30/user/month on top of an existing Microsoft 365 subscription, Copilot is the obvious choice if your company already lives in Word, Outlook, Teams and SharePoint. It is less of a cross-app universal search than Glean, but the integration with Microsoft’s own ecosystem is unmatched.

Guru

Guru focuses on verified, single-source-of-truth knowledge management at about $25/user/month, with credit-based AI usage. It is a better fit if your priority is a curated, trustworthy internal knowledge base rather than indexing everything everywhere.

GoSearch

GoSearch is a direct, more affordable challenger, starting around $20-25/user/month with a genuine free tier and published pricing. It offers AI chat and semantic search across connected apps, making it the pragmatic pick for teams that want Glean-style capability without the opaque enterprise contract.

Final Verdict: Is Glean Worth It?

Glean is, technically, the best-in-class enterprise AI search and assistant platform. The permissions-aware results, breadth of connectors, and the agent platform are genuinely strong, and the adoption numbers and $7.2B valuation back that up. If you are an enterprise with the budget and the scattered-knowledge problem it solves, it earns its keep.

The catch is everything around the product: no published pricing, no free plan, a 100-seat minimum, a six-figure all-in cost, and renewals that can spike sharply. If you are at enterprise scale, Glean is worth a serious look and probably a proof-of-concept. If you are anything smaller, look at Copilot, Guru or GoSearch instead, this tool was never built for you.
