Glean vs Copilot Pricing: What Each One Costs Per User

Two products end up on the same slide more often than any other pair in this category, and the reason is that somebody summarized both of them as "AI that answers questions about our company." That summary is true and it hides everything that matters. One of them is an assistant bolted into the productivity suite you already license. The other is a search platform that was built to reach across every system your company runs.

Here is what each actually costs in August 2026, what each can genuinely see, and the honest test for which problem you have.

How much does Microsoft 365 Copilot cost?

Microsoft publishes its prices, which already puts this half of the comparison on solid ground. The enterprise add-on, Microsoft 365 Copilot, is $30 per user per month on an annual commitment, layered on top of an eligible Microsoft 365 license. You are not buying Copilot instead of Microsoft 365, you are buying it as well.

The small and mid-market SKU, Copilot Business, has been unusually volatile. It moved from $18 to $21 per user per month in July 2026. Reading the same page on August 21, 2026, it now shows as "Originally starting from $21.00 now starting from $18.00 user/month, paid yearly", with the monthly option at $25.20. In eight weeks the number went up and came back down. If you are building a three-year budget model on that figure, put a note next to it, because a promotional price is not a list price and Microsoft has demonstrated it will move this one.

There are bundles too. Business Premium with Copilot lists at $32.00 per user per month billed yearly, Business Standard with Copilot at $23.50. Whether a bundle beats the add-on depends entirely on what you already own, which is the sort of question your Microsoft reseller can answer in ten minutes and a comparison article cannot.

One more line that catches people out at renewal: agent work built in Copilot Studio is billed separately, in Copilot Credit packs at $200 per pack per month for 25,000 credits, and it is a tenant-wide meter rather than a per-seat one. Teams that plan a serious agent rollout should model that line explicitly rather than assuming the per-seat price covers everything. We break the whole family down on our Microsoft Copilot pricing page.

How much does Glean cost compared to Copilot?

You cannot compare them directly from public information, and anyone who tells you otherwise is quoting a number they cannot source. We read glean.com/pricing on August 21, 2026. It has no plans, no tiers, no per-seat figure and no seat minimum. It has a button that says get a demo. That is the complete published disclosure.

What exists instead is aggregated contract data from software buying marketplaces, which report on real signed deals. They are worth reading and they disagree with each other, which is itself the most useful finding.

Look closely at the two Glean rows. Vendr's average across every deal it has handled sits below SpendHound's average for small and mid-sized businesses alone. Both platforms describe their figures as real contract data rather than estimates. They cannot both be representative of the same market, and the honest conclusion is not that one of them is lying. It is that Glean contracts vary so widely that whichever sample you land in dominates the answer. There is no Glean price to discover, only a quote to negotiate. We walk through the full picture on our Glean pricing breakdown.

Which one can actually see more of your company?

This is the question that should decide the purchase, and it is answerable with a spreadsheet rather than a demo.

List the last twenty questions your team asked each other in Slack or Teams. Not hypothetical questions, real ones, including the awkward ones. Next to each, write down which system holds the answer. Then count. If sixteen of the twenty land in SharePoint, Teams, Outlook or an Office document, Copilot is very likely the right purchase and the economics are excellent, because you are adding $30 to a license you already hold rather than starting a new vendor relationship.

If eight of them land in Salesforce, Jira, Zendesk, Notion or Confluence, the picture changes. Copilot can reach those systems, but through Microsoft Graph connectors, which means scoping, indexing, permissions mapping and someone owning it. Sold as a checkbox, delivered as a project. Glean treats cross-app retrieval as the product rather than an extension of it, and that difference is what the premium buys.

Neither answer is embarrassing. Companies that genuinely live inside Microsoft 365 should stop reading comparison articles and buy Copilot. Companies whose knowledge is scattered across a dozen SaaS tools should stop hoping the suite assistant will grow into the job.

How do Glean and Copilot handle permissions?

Both inherit permissions from the source rather than making up their own, which is correct. The difference is what happens when the source's permissions are a mess.

Copilot inherits Microsoft 365 permissions, which means Copilot is exactly as good as your existing SharePoint hygiene and no better. This is the single most common unpleasant surprise in Copilot rollouts. A site somebody shared with "everyone in the organization" in 2019 was effectively invisible because nobody could find it. Give the whole company a search box that reads natural language, and it stops being invisible immediately. The oversharing was always there. Copilot just made it legible.

There is a related limit worth knowing before you plan a rollout, straight from Microsoft's own documentation: when more than 10,000 distinct users or security groups have access to an item, the item is not searchable by any user. That is a real cliff on large tenants, and it produces the confusing outcome where the most widely shared document in the company is the one nobody can find. Our write-up on SharePoint search covers the rest of the crawler limits, including the 2 million character parse ceiling and the 30 second per item parsing budget.

Glean handles item-level permissions at query time across every connected system, and does it well. The harder problem it faces is breadth: enforcing entitlements correctly across a dozen different permission models, each with its own semantics, is genuinely difficult engineering. Whichever product you pick, test this deliberately during the trial. Have someone in a restricted role ask five questions whose answers sit in documents they are not entitled to open, and watch what comes back. Almost nobody runs this test, and it is the one that catches the failures that end careers. Permission-aware AI search explains what a correct result looks like.

What about Copilot Studio, agents, and where this is all going?

Both vendors are moving in the same direction, away from answering questions and toward completing tasks. Microsoft's version is Copilot Studio, where you build agents that take actions, billed through those tenant-wide credit packs. Glean has built out agent functionality on the same premise.

Be careful about buying a search product on the strength of an agent roadmap. The agent demo is always impressive and the value always depends on plumbing that nobody has built yet at your company. If what you need this quarter is for people to find the shipping policy without asking in Slack, buy the thing that finds the shipping policy. Task automation is a real category with real returns, but it is a separate purchase with separate work behind it, whether that turns out to be an assistant that drafts the email and files the document or a workflow built inside a platform you already own.

The other reason to be careful is that the ground keeps moving. In the eighteen months to August 2026 this category has seen Amazon Kendra go into maintenance mode, Amazon Q Business close to new customers, Elastic Workplace Search reach end of life, Dashworks get acquired by HubSpot, Qatalog get acquired by ClickUp, and Moveworks get acquired by ServiceNow for $2.407 billion. We compared the two independents that buyers most often confuse in Moveworks vs Glean. Roadmap promises in a market consolidating this fast should be discounted heavily.

Five questions to ask before you sign either contract

1. What percentage of my twenty real questions can this product answer today, with the connectors included in this quote? Not on the roadmap. Today, in this quote.
2. Which connectors are included in the license and which are professional services? This is where two quotes silently stop being comparable.
3. What is the minimum seat count and the minimum contract term? Ask in the first fifteen minutes. A seat floor disqualifies more buyers than a seat price does, and it is invisible until somebody says it out loud.
4. Is the AI functionality included in the per-seat figure, or billed separately? For Copilot the honest answer is that agent work is metered separately. For Glean, public accounts describe AI as a separate line and Glean does not confirm the structure publicly.
5. What is the renewal uplift, in writing, capped? You will never have more leverage than you do before the first signature.

So which should you buy?

Buy Microsoft 365 Copilot if the overwhelming majority of your institutional knowledge lives in Microsoft 365, if your SharePoint permissions are in reasonable shape or you are willing to fix them first, and if you want a published price you can put in a budget this week. At $30 per user per month on top of a license you already hold, it is the strongest value in this category for companies that genuinely fit that description.

Buy Glean if your answers are scattered across many systems, you have the headcount to clear a seat floor reported at 100 to 250 users, and you have budget for a six-figure annual commitment and the procurement cycle that comes with it. It is the category leader for good reasons and it does the cross-app job properly.

And consider a third option if you recognized your company in neither paragraph, which is where a lot of US mid-market teams land: knowledge in six or seven systems, between 50 and 500 people, and no appetite for a quote-only enterprise process. That is the gap we built unified search for, with a published per-seat price and no hard seat minimum. If you want to see how the rest of the field lines up first, Glean alternatives compares ten products on price, connectors and permissions, and enterprise search tools covers the wider market.

Whichever way you go, run the twenty-question test before you run the demo. It takes an afternoon and it is the only part of this process that tells you something the vendors cannot.
