8 Best Glean Alternatives in 2026

Key takeaways

• Microsoft 365 Copilot is the best Glean alternative for Microsoft 365 organizations, Gemini Enterprise is the pick for Google Workspace, and Onyx is the best open-source option you can host yourself.

• Guru suits teams that need answers someone has checked, and Atlassian Rovo comes included with paid Jira and Confluence Cloud plans.

• ChatGPT and Claude now search company apps through connectors, and both publish their prices.

• Glean doesn't publish pricing; buyers report annual contracts that start in the tens of thousands of dollars.

Why teams look for Glean alternatives

Glean is still the benchmark for enterprise AI search. It indexes a company's apps, respects each user's permissions and answers questions across all of it, and it passed $300 million in annual recurring revenue in May 2026, according to the company. The usual reasons to look elsewhere are cost and fit. Glean doesn't publish prices and routes buyers to a demo request, and buyers report per-seat prices in the $50 to $75 a month range with seat minimums, so small teams are often priced out.

What changed this year: The suites caught up. Google folded Agentspace into Gemini Enterprise, ChatGPT and Claude added search across connected work apps, and Amazon replaced Q Business with Amazon Quick. Meanwhile several standalone options were bought by bigger platforms: HubSpot bought Dashworks, Workday bought Sana, and ServiceNow bought Moveworks.

How we ranked: We weighed how well each tool searches across many apps, whether answers respect existing permissions, setup effort, how open its pricing is, and how far it reaches beyond its own ecosystem. We did not run a hands-on bake-off for this edition.

The 8 Glean alternatives compared

1. Microsoft 365 Copilot

Microsoft 365 Copilot is the obvious swap if your company already runs on Microsoft 365.

What works: Search, chat and agents sit inside Outlook, Teams, Word and SharePoint, grounded in Microsoft Graph, and admins manage it with the identity and compliance tools they already use. Connectors bring in content from outside Microsoft.

What doesn't: It's strongest on Microsoft content. Knowledge in other apps comes through connectors and tends to surface less reliably than it does in Glean, and you need a qualifying Microsoft 365 license first.

Best for: Organizations standardized on Microsoft 365. It's $30 per user a month paid yearly, as of October 2026, and Microsoft 365 Business customers can add Copilot Business for $21 a month.

2. Gemini Enterprise

Gemini Enterprise, which absorbed Google Agentspace, is Google's answer to Glean.

What works: It searches Google Workspace and more than 100 other apps, including Microsoft 365, Slack, Jira and Salesforce, while data stays where it lives and results follow each user's permissions. A no-code builder lets teams make their own agents, and the Business edition has a 30-day free trial.

What doesn't: The Business edition gets only a selection of connectors and basic admin controls. The fuller editions are priced through sales, like Glean.

Best for: Google Workspace organizations. Business starts at $21 per seat a month for teams of up to 300, as of October 2026.

3. Onyx

Onyx, formerly Danswer, is the open-source take on Glean's search-first design.

What works: You can host it yourself, plug in the language model of your choice and connect more than 40 apps, with answers that inherit the source permissions. A hosted Business plan covers teams that don't want to run it.

What doesn't: It has far fewer connectors than Glean, and self-hosting means your engineers own the upkeep.

Best for: Security-minded or budget-conscious teams with engineering time. Business is $20 per user a month billed annually, as of October 2026.

4. Guru

Guru adds human verification to AI answers.

What works: Subject-matter experts verify knowledge on a schedule, so answers come with citations and an owner. It respects permissions, connects to more than 100 tools and can deliver answers to other AI tools through MCP.

What doesn't: Answers are only as good as the knowledge your experts keep current, and like Glean it no longer publishes a per-seat price.

Best for: Support, sales and HR teams that need answers they can audit. Pricing is quoted by sales.

5. ChatGPT Business

ChatGPT Business gives teams the assistant many already use, with company knowledge attached.

What works: Its company knowledge feature answers from connected apps like Slack, SharePoint, Google Drive, Gmail and GitHub, with citations, and it's quick to roll out. Enterprise adds stronger admin and data controls.

What doesn't: It's an assistant first. There's no dedicated company index on the scale of Glean's, so answers depend on what the connectors return.

Best for: Teams that want a general AI assistant that can also search work apps. Business is $20 per user a month billed annually, as of October 2026.

6. Claude

Claude Team and Enterprise plans pair Anthropic's model with search across connected tools.

What works: Both plans include enterprise search across connected apps, and Claude is strong at reading long documents and writing from them. Enterprise has a 20-seat minimum, low for this category.

What doesn't: Like ChatGPT, it isn't a dedicated search index, and Enterprise adds usage billing on top of seats, which makes costs harder to predict.

Best for: Teams that analyze and write from internal documents. Team is $20 per seat a month billed annually, as of October 2026.

7. Atlassian Rovo

Atlassian Rovo is AI search and agents built into Atlassian Cloud.

What works: It comes included with paid Cloud plans of Jira, Confluence and Jira Service Management, so there's nothing extra to buy, and it connects to third-party apps as well as Atlassian content.

What doesn't: It's centered on Atlassian, you need to be an Atlassian Cloud customer, and agent use runs on monthly credits.

Best for: Engineering and product organizations that live in Jira and Confluence. Included with Standard plans and up, as of October 2026.

8. Amazon Quick

Amazon Quick replaced Amazon Q Business as AWS's workplace AI suite.

What works: It combines search and chat over company data with dashboards and automation, and its pricing is published.

What doesn't: Its dashboards and deeper data connections lean on AWS, and the move from Q Business means older guides and reviews describe a different product.

Best for: Organizations already on AWS. Plus is $20 per user a month billed annually, as of October 2026.

Didn't make the cut

Dashworks is a lighter, cheaper alternative, but HubSpot bought it in 2025 and its team now builds AI search for HubSpot, so its future as a standalone product is unclear.

Moveworks and Sana are now part of ServiceNow and Workday, so they make sense mainly inside those platforms.

Perplexity Enterprise is strong for research that mixes the web with internal files, but it's weaker as a company-wide index.

Coveo is a good fit for customer-facing and service search, but it's a bigger build than most teams replacing Glean want.

How to choose a Glean alternative

Follow your suite. If nearly everything lives in Microsoft 365 or Google Workspace, that vendor's assistant will search it best and is the simplest to approve.

List the apps that matter. Check each tool's connectors against the five or six apps where your answers live, not the total connector count.

Test permissions with real accounts. Sign in as people with different access and confirm nobody sees a document they shouldn't.

Price the whole rollout. Seat minimums, usage fees and the hours needed to set up connectors often matter more than the per-seat number.
