AgentOS vs Glean: enterprise AI, or a company memory any team can start with?

Updated October 12, 2026 · by Ashtin Dowler · 8 min read

Glean is the enterprise standard for AI that understands a company. AgentOS brings the same idea to teams that can't, or don't want to, buy enterprise software. Glean is excellent: deep search across hundreds of apps, strict permissions and a long list of certifications. It's also sold through a sales team, with no public prices, and it's built for large organisations. AgentOS is free to start, sets up in an afternoon, and lets anyone describe a workflow in plain language. If you're a large company with a budget and a rollout plan, look hard at Glean. If you're a smaller team that wants to start this week, AgentOS is the easier way in.

What does Glean do well?

Glean is the product most people mean when they talk about AI that knows a company. It connects to more than 275 apps and builds a searchable picture of everything in them. Ask a question and it answers from your own documents, tickets and conversations.

Its handling of permissions is the standard others are measured against. Glean mirrors the access rules of each source and checks them every time someone asks, so a person never sees an answer drawn from something they couldn't open themselves.

It has grown well beyond search. There's an assistant, an agent builder, a choice of more than forty models, and approval prompts before an agent writes to another system. Glean also offers an MCP server that works with Claude, ChatGPT and Cursor, so its knowledge isn't locked inside its own app. The compliance list is long: SOC 2 Type II, ISO 27001, ISO 42001, HIPAA and more.

Where is Glean a hard fit?

The limits are about size and buying, not quality.

Glean is sold to enterprises. Its pricing page shows no plans or prices, only a button to book a demo. Third-party estimates put a typical contract in the tens of thousands of dollars a year, with deployments usually starting at a hundred users or more. We can't confirm those numbers, and they tell you who the product is aimed at.

It's a project. Connecting hundreds of apps with enterprise permissions involves IT, security and a rollout plan. That's right for a company of two thousand people. It's a lot for a team of thirty that wants to try something this month.

Reviewers are mostly positive. The complaints that come up are that it sometimes can't find the right resource, and that the subscription is expensive.

How is AgentOS different?

AgentOS is built on the same idea, that AI is only as good as what it knows about your company, for teams that don't have an enterprise budget or an IT department to run a rollout.

You sign up and connect the apps your knowledge lives in: Gmail, Slack, Google Drive, your CRM. There's no sales call to get started. AgentOS keeps one shared, current picture of the business, and you decide what each person and each tool can see.

Claude, ChatGPT, Cursor and your own agents connect over MCP, so every tool your team uses starts out knowing the same clients and history. Answers link back to the email, call or document they came from.

You can also put it to work. Describe a workflow in plain language, and Otto, the agent built into AgentOS, builds it and runs it on a schedule. Important changes wait for a person to approve them. And you see AI use and spend across the tools you've connected in one place.

Should you choose Glean or AgentOS?

Choose Glean if you're a large organisation with hundreds of apps, strict compliance needs, and the budget and people for an enterprise rollout. It's the most proven product of its kind.

Choose AgentOS if you're a smaller team, you want to start without a sales process, or what you most need is workflows that run on your company's knowledge and one view of what AI costs.

There's a fair middle case too: a growing company that starts with AgentOS now and looks at Glean again when it has a thousand people and a security team.

What about other Glean alternatives?

Roundups usually name Microsoft 365 Copilot, Notion AI, Coveo, Elastic, GoSearch and Onyx. Two of those we've compared directly: AgentOS vs Microsoft Copilot and AgentOS vs Notion AI. For a product closer to Glean in spirit but aimed at smaller teams, see AgentOS vs Dust.
