Glean Alternatives: Enterprise Search Compared (2026)

The best Glean alternative is usually the AI search built into the suite your company already pays for. Microsoft 365 shops should start with Microsoft 365 Copilot, Google Workspace shops with Gemini Enterprise, and teams with a mix of tools should compare Claude and ChatGPT business plans. Notion and Dust are lighter options for smaller teams.

This guide is for IT, operations and knowledge leads at companies of roughly 20 to 1,000 people who have looked at Glean and want to know what else can answer "where is that document?" across their tools. For a full review of Glean itself, see our Glean App of the Week.

Key takeaways

• Glean does not publish prices and sells through demos. It lists more than 250 connectors plus search, an assistant and an agent builder.
• Microsoft 365 Copilot is $30 per user a month billed yearly for enterprise, and the Business add-on is $18 billed yearly under a promotion that ends 31 December 2026 (normally $21). It searches Microsoft 365 and other systems through 100+ connectors.
• Gemini Enterprise Business starts at $21 per seat a month for up to 300 seats, with connectors to Microsoft 365, Google Workspace, HubSpot and Jira.
• Claude Team includes enterprise search across your organization from $20 per seat a month billed yearly. ChatGPT Business includes company knowledge across 60+ apps.
• Notion Business ($20 per member a month) and Dust (free seat, Pro from 24 EUR) cover smaller teams. Notion's Enterprise Search is still in beta.

All prices are as of October 2026 and taken from each vendor's own pages.

Why do companies look for Glean alternatives?

Glean is built for large enterprises with many tools. Its own site describes enterprise search, an assistant it calls "your enterprise AI coworker", and a builder for managing agents, with customers such as Zillow and Ericsson running thousands of agents. That depth is the reason to buy it, and also the reason teams look elsewhere.

Three things push buyers to compare:

1. No public price. Glean's site has "Get a demo" and no plan table. Smaller companies often want a number before a sales cycle.
2. Overlap with tools you already pay for. Microsoft, Google, Anthropic, OpenAI and Notion now bundle search across company data into seats many teams already buy.
3. Fewer sources than Glean is built for. If your knowledge sits in three or four apps, 250 connectors is more than you need.

How do the Glean alternatives compare?

Is Microsoft 365 Copilot a good Glean alternative?

For companies that run on Microsoft 365, it is the first one to test. The enterprise add-on is $30 per user a month billed yearly, or $31.50 paid monthly with an annual commitment, and it needs a qualifying Microsoft 365 plan. Microsoft says it searches across work data, including line-of-business applications through more than 100 connectors.

Smaller companies can use the Business add-on at $25.20 a month paid monthly or $18 billed yearly. The $18 rate is a promotion from 1 July to 31 December 2026, for the first year only and for existing customers on an eligible Business plan. The regular yearly price is $21.

Watch for usage billing. Microsoft lists Cowork, Code, Autopilot and the Work IQ APIs as billed by usage on top of the license.

Is Gemini Enterprise a good Glean alternative?

For Google Workspace companies, yes. Gemini Enterprise Business starts at $21 per seat a month, needs no IT setup according to Google, and covers up to 300 seats with 25 GiB of pooled storage and indexing per seat. It connects to Microsoft 365, Google Workspace, HubSpot and Jira and includes a no-code workflow builder for agents.

The Standard and Plus editions start at $30 per seat a month through sales and add higher limits, bring-your-own agents, VPC Service Controls, customer-managed encryption keys and data residency. Google lists more than 100 integrations, including Slack, Confluence, Notion, Salesforce and ServiceNow, and says access follows each user's existing permissions. You can trial the Plus edition free for 30 days.

Should you use Claude or ChatGPT instead of a search platform?

If your goal is "ask a question and get an answer from our documents", a business AI assistant may be enough. Both vendors now bundle search across company tools into their team plans.

• Claude. Team seats cost $20 a month billed yearly or $25 monthly, for 2 to 150 seats, and the plan lists "enterprise search across your organization". Enterprise is $20 per seat a month billed yearly plus usage at API rates, with a 20-seat minimum. Connectors are available on every plan, with admin controls on Team and Enterprise. See our works with Claude collection for tools that plug in.
• ChatGPT. Business includes company knowledge and connects to 60+ apps, including Slack, Google Drive, SharePoint and GitHub. Enterprise is custom priced. For a side by side of the assistants themselves, read ChatGPT vs Claude vs Gemini for business.

The trade-off: an assistant answers well from connected sources, but a dedicated platform like Glean puts more work into indexing, ranking and admin controls across hundreds of apps. You can also combine them. Glean runs an MCP server that works with Claude, ChatGPT, Cursor and VS Code, and each person signs in with their own access.

What about Notion and Dust for smaller teams?

Notion makes sense when your wiki, docs and projects already live there. The Business plan is $20 per member a month and includes Notion Agent and Enterprise Search, which Notion still marks as beta. Its pricing page names Slack, Microsoft Teams and GitHub, with Jira, Box, OneDrive, Salesforce and Asana also in beta. Free and Plus only get a limited trial of Notion AI.

Dust is for teams of up to 100 people that want to build agents on company data. A free seat includes 500 credits for life. Pro is 24 EUR per seat a month billed yearly (30 EUR monthly) with 8,000 credits a month, and Max is 120 EUR with 40,000 credits. The Business plan allows up to 3 connectors and 5 remote MCP servers. Enterprise adds unlimited connectors, SCIM, audit logs and US or EU data residency. Credits do not roll over, so budget for usage.

How to choose a Glean alternative

1. Start with your suite. If almost everything lives in Microsoft 365 or Google Workspace, pilot that vendor's option first. It is often already in your contract.
2. Count your real sources. List the apps where answers actually live. Under five, an assistant or Notion may be enough. Dozens, with strict permissions, is where Glean earns its price.
3. Test permissions before accuracy. Put a restricted document in a connected source and check that people without access cannot find it.
4. Run the same 20 questions in every pilot. Use questions your team asks every week and score the answers.
5. Price the full seat. Add base licenses, usage billing and credits. Our free AI Tool Vendor Evaluation Scorecard gives you a weighted sheet for this, and the AI vendor security checklist covers procurement questions.

Bottom line

Glean is still the strongest pick for large enterprises with tool sprawl and strict governance needs. Most companies under a few hundred people should first test the search that comes with Microsoft 365 Copilot or Gemini Enterprise, or a Claude or ChatGPT team plan, before starting a Glean sales process.
