Glean AI in 2026:
Your Company Has All the Answers. Nobody Can Find Them.
Every team has that one person everyone asks because they "just know where everything is." Glean is what happens when you give that superpower to everyone in the company — at the same time.

Valuation (2025)
Picture this: a new engineer joins your team. She needs to find the API authentication spec written six months ago, the Slack thread where the edge case was debated, the Confluence page that documents the final decision, and the GitHub PR where it was actually implemented. Without Glean, she spends half a day pinging four different people. With Glean, she types one question in plain English and gets the answer — with sources — in under ten seconds.
That's not a marketing pitch. That's the actual problem Glean was built to solve. Enterprise knowledge is scattered across dozens of apps, locked inside silos, and invisible to anyone who wasn't in the room when the decision was made. Glean acts as the connective tissue between all of it: a single AI-powered search layer that sits on top of your entire company's data and makes every piece of institutional knowledge findable, surfaceable, and usable — by anyone, instantly.
"The most expensive resource in any company isn't software or office space. It's the time employees waste looking for information that already exists somewhere."
What Is Glean AI?
Glean is an AI-powered enterprise search and knowledge platform founded in 2019 by ex-Google engineers, including former Google search lead Arvind Jain. The core product connects to every tool your company uses — Google Drive, Slack, GitHub, Jira, Confluence, Salesforce, Notion, Zendesk, and 100+ others — and builds a unified, permission-aware search index across all of them. Ask Glean anything, and it searches every connected app simultaneously, ranks the most relevant results, and synthesizes a direct answer using generative AI.
What makes Glean different from a simple search tool is its understanding of context. It knows who you are, what team you're on, what projects you're involved in, and what information you have access to. A sales rep and an engineer can ask the same question and get different results — each perfectly tailored to their role and permissions. The AI doesn't just find documents; it understands the organizational graph behind them.
💡 Important: Glean never trains its AI on your company's data or shares it with other organizations. Every deployment is isolated, permission-respecting, and SOC 2 Type II certified. Your files stay yours — Glean just helps you find them.
Core Features
🔗
Universal Connector Hub
One integration layer for 100+ enterprise apps. Connect Slack, Drive, GitHub, Jira, Salesforce, Confluence, and more — then search all of them simultaneously with a single query. No more app-switching to find a buried file.
🤖
Glean Chat (AI Assistant)
An internal ChatGPT that actually knows your company. Ask it about company policies, project status, past decisions, or technical specs — and it pulls real answers from your actual data, with citations you can verify.
🔐
Permission-Aware Search
Glean respects every permission setting from every connected app. If an employee shouldn't see a document, Glean won't surface it — even in AI-generated summaries. No accidental data leaks across teams or levels.
🧠
People & Expertise Graph
Glean maps who knows what across your organization. Search for a topic and it tells you not just which documents exist — but which colleagues are the actual subject-matter experts. Organizational memory, made searchable.
⚡
Glean Agents
Automated workflows that trigger on knowledge events. An agent can summarize new Confluence pages for your team, draft answers to recurring support tickets, or keep a team wiki up-to-date — autonomously, in the background.
📊
Knowledge Analytics
Admins see what people are searching for and not finding — revealing knowledge gaps in real time. If 40 employees searched for something and got no results, that's a signal your documentation needs updating.

Pros & Cons
✓ What It Gets Right
- Genuinely unified search — one query, every connected app, simultaneously, in seconds.
- Permission-aware AI that respects your existing access controls without extra configuration.
- Glean Chat gives real answers grounded in your actual company data — not generic LLM hallucinations.
- The People Graph is underrated: finding internal experts is just as valuable as finding documents.
- Glean Agents automate knowledge workflows that used to require a full-time internal ops person.
- SOC 2 Type II certified, GDPR-compliant, and built for enterprise security from the ground up.
✗ Where It Falls Short
- No self-serve onboarding — every new customer goes through sales, which slows adoption for smaller teams.
- Per-seat pricing adds up quickly at scale; at 500+ users, the bill becomes a significant line item.
- Integration quality varies — core apps (Slack, Drive, GitHub) are excellent; niche tools may have shallower indexing.
- Initial setup and IT configuration takes real time — this is not a tool you're fully live on in an afternoon.

Who Should Use It?
Best for: Mid-size to large companies (50+ employees) that use multiple disconnected SaaS tools and constantly lose time to "do you know where the doc is?" conversations. Engineering teams onboarding new hires. Customer success teams that need instant access to product knowledge. Operations teams trying to reduce repetitive internal Q&A. Any organization where institutional knowledge currently lives in the heads of a few people — and those people are becoming bottlenecks.
Look elsewhere if: You're a solo founder or tiny team — the pricing and enterprise setup overhead won't justify the cost. If your company is fully standardized on Microsoft 365, Copilot might be sufficient and more cost-effective. If your primary knowledge problem is documentation quality (not findability), no search tool can fix a culture that doesn't write things down.
Glean is one of those tools that's difficult to appreciate until you've felt the pain it solves. And most people in companies larger than 50 people feel that pain every single day — they just call it "normal." The average knowledge worker spends nearly 20% of their week searching for information. Glean is a direct attack on that number, and in the companies that deploy it well, the ROI is embarrassingly obvious within 30 days.
The feature that genuinely sets Glean apart from every competitor isn't the search — it's the permission layer. Getting AI to answer questions from your internal data sounds impressive until you realize that most implementations leak sensitive information across org boundaries. Glean solved that problem in a way that's invisible to end users and watertight from a security standpoint. For enterprises, that's not a nice-to-have; it's the entire ballgame.
The most common question I get is: "What about Microsoft Copilot?" The honest answer is: if your company is 95% Microsoft stack, Copilot is cheaper and simpler. But the moment you use Slack instead of Teams, or GitHub instead of Azure DevOps, or Notion instead of SharePoint, Glean pulls dramatically ahead. Its stack-agnostic architecture is its superpower — and it's not something Microsoft can replicate without eating its own ecosystem.
My honest frustration with Glean is the sales-only entry point. The fact that a curious IT lead or operations manager can't spin up a free trial and explore the product themselves is a genuine barrier. Glean's team knows this — it's a deliberate enterprise motion, not an oversight — but it costs them real adoption from companies that could benefit enormously from the product.
If your team regularly loses institutional knowledge when people leave, wastes hours tracking down information across tools, or onboards new hires slowly because "it just takes time to learn where everything is" — Glean is the closest thing to a structural fix I've seen. Request the demo. It's worth an hour of your time.

ToolRadar Editorial
Glean is the gold standard for enterprise knowledge search in 2026. Its permission-aware unified search, People Graph, and Glean Agents make it the most complete solution for companies that are serious about making institutional knowledge accessible at scale. The price tag and enterprise-only sales motion keep it out of reach for small teams — but for the right organization, Glean doesn't just save time. It changes how the entire company operates.
