COMPARE · GLEAN ALTERNATIVES
Cross-industry
The best Glean alternatives depend on why you are leaving. If you need AI that answers from your operational systems (ERP, property management, policy admin, EHR and billing) and agents that do work your team approves, OutcomeCatalyst is the closest fit, delivered and run for you. If you want cheaper workplace search across documents and chat, look at Microsoft 365 Copilot, GoSearch, Onyx or Guru. And if your main job is finding files across Google Drive, Slack and Confluence, Glean itself is still one of the strongest options.
Why companies look for Glean alternatives
Glean is good at what it was built for. It calls itself "Enterprise AI that understands your company," lists 275+ connectors to work apps and data sources, and builds permission-aware access in from the start, so people only see what they are allowed to see (Glean, 2026). Glean's site cites enterprise customers running thousands of agents on top of that index.
So why the search for alternatives? Two reasons come up again and again.
Cost and contract size. Glean does not list prices on its website; buying starts with a demo request (glean.com, checked October 6, 2026). Third-party buyer guides fill the gap. GoSearch, a Glean competitor, reports a roughly 100-seat minimum and an entry point near $60,000 a year (GoSearch, 2026). Slite, also a competitor, cites Vendr transaction data putting the median Glean contract at $98,700 a year (Slite citing Vendr, 2026). Treat those as reported figures, not Glean's own terms. Still, for a 75 or 150 person firm, the numbers explain the search volume.
Shape of the problem. This one gets less attention. Every popular Glean alternatives list frames the category as workplace search: find the doc, summarize the thread, answer the HR question. But a lot of mid-market operators are not stuck on finding documents. They are stuck on questions like "which of our open submissions are missing loss runs," "what did we actually pay on this vendor's last six POs," or "which leases roll in the next 18 months with below-market rent." Those answers live in structured systems of record, and the useful next step is an action, not a link.
That split decides which alternative is right for you. The rest of this page is organized around it.
Glean alternatives at a glance
Tool | Best for | Not a fit for | Needs a data team? |
|---|---|---|---|
OutcomeCatalyst | Operators who need AI on ERP, CRM, property management, policy admin or EHR data, plus agents that act | Company-wide document and chat search across hundreds of SaaS apps | No. OC delivers and runs it |
Microsoft 365 Copilot | Teams already living in Word, Excel, Outlook and Teams | Answers from line-of-business systems outside Microsoft without extra build work | No for basics; yes for custom agents on other systems |
GoSearch | Mid-size teams that want federated workplace search and no-code agents with a self-serve start | Deep reasoning over structured operational records | No for setup; some admin time |
Onyx | Security-minded teams that want open-source search they can self-host | Companies with no one to run infrastructure | Yes, if you self-host |
Guru | Support, sales and HR teams that need verified, governed answers | Live numbers from systems of record | No. Needs content owners |
Coveo | Large enterprises adding AI search to commerce, service and websites | A small internal team wanting a quick workplace assistant | Usually yes |
1. OutcomeCatalyst: best Glean alternative for operational AI on system data
OutcomeCatalyst (OC) starts where workplace search stops. It connects the systems a mid-market operator already runs, such as ERP, CRM, property management, policy admin, EHR and billing, plus documents and spreadsheets, into one governed AI context layer built on a knowledge graph. We call that the brain. Then OC deploys AI agents trained to decide the way your veteran employees do, and your team approves the work before it counts.
The difference from Glean is less about features and more about what the AI is grounded in. A search index is very good at "where is the document that says X." A knowledge graph over your systems of record is built for "what is true about this deal, this policy, this claim, this order right now, across every system that holds a piece of it." If you want the longer version of that distinction, read what an AI context layer is and our breakdown of knowledge graphs vs vector databases vs semantic layers.
The second difference is delivery. OC is done-for-you. We scope the systems, build the brain, train the agents and run them. You do not need a data team, and nobody on your side has to become a prompt engineer.
What it looks like in practice
Commercial real estate: underwriting and diligence agents that pull rent rolls, operating statements and lease abstracts into one view, and reporting agents that draft investor updates from the numbers.
Specialty and MPL insurance: submission and triage against your appetite, and policy file integrity checks before audit finds the gaps.
Healthcare operations: claims and appeals work drawn from billing and EHR data.
Manufacturing and distribution: quote to fabrication and direct spend agents that read the ERP instead of a summary of it.
Professional services: answers that join the CRM, the time and billing system and the engagement files, so partners stop asking three people for one number.
Best for
Operators in commercial real estate and land acquisition, professional services, MPL and specialty insurance, healthcare operations, and manufacturing and distribution, whose hardest questions sit in structured systems and who want agents doing real work under human approval.
Not a fit for
Companies whose main need is enterprise search across Google Drive, Slack, Confluence and a long tail of SaaS apps. Glean is a better fit there, and so are several tools below.
Teams that want a self-serve product they can sign up for and configure themselves this afternoon. OC is delivered, not self-serve.
Anyone looking for a general chat assistant for writing emails and decks. Microsoft 365 Copilot does that job inside the apps you already use.
2. Microsoft 365 Copilot: best if you already live in Microsoft
Microsoft 365 Copilot is AI built into Word, Excel, PowerPoint, Outlook and Teams, with Copilot Chat grounded in your Microsoft 365 work data. It is an add-on: Microsoft requires a qualifying Microsoft 365 plan, and the Business version is sold for organizations of up to 300 users. On October 6, 2026, Microsoft's Business page listed it at $21 per user per month on annual billing, shown with a promotional price of $18, or $25.20 on monthly billing (Microsoft, 2026). Check the page before you budget, because promotions change.
Best for: firms standardized on Microsoft 365 that want drafting, meeting summaries and search over email, SharePoint and Teams without adding a new vendor. For many 75 to 150 person companies this is the cheapest serious Glean alternative because the licensing relationship already exists.
Where it falls short for an operator without a data team: Copilot is strongest on Microsoft content. Getting it to reason over a property management system, a policy admin platform or an ERP outside the Microsoft stack means building connectors or custom agents, which is work someone has to own. It answers questions well. It does not, out of the box, know how your underwriter decides.
3. GoSearch: best self-serve workplace search for mid-size teams
GoSearch describes itself as "an AI enterprise search knowledge layer powering custom agents and no-code workflows," with 100+ app connectors and a federated approach that pulls live information from sources rather than copying everything into an index (GoSearch, 2026). Its site offers a free start, which is the opposite of a demo-only sales motion.
Best for: mid-size companies that want something close to Glean's experience (search across apps, plus agents anyone can build with plain-language instructions) and want to try it before signing a large contract.
Where it falls short for an operator without a data team: it is still workplace search at heart. Federated search over apps is good for documents, tickets and messages. It is not designed to model how a rent roll, a GL and a lease abstract relate to each other, or to run multi-step operational decisions on that data.
4. Onyx: best open-source, self-hosted option
Onyx calls itself "Open source enterprise search & AI assistant." It runs in your own cloud or on bare metal, offers 50+ connectors synced and indexed continuously, and includes agents and actions (Onyx, 2026). Onyx also publishes a Glean cost calculator, which is useful if you are building a budget case, keeping in mind that a competitor built it.
Best for: teams with strict data residency or security requirements, and engineering-led companies that want to audit the code and control where it runs.
Where it falls short for an operator without a data team: self-hosting means someone runs the infrastructure, upgrades and connectors. If you do not have that person, the license savings get spent on staff time or consultants. And like the other search tools, it is built around indexing content, not reasoning over operational records.
5. Guru: best for verified knowledge your team can trust
Guru positions itself as "The Governed Knowledge Layer for Enterprise AI." It structures and governs company knowledge so people and AI tools get answers that have been verified, and its Knowledge Agents flag stale content and draft updates (Guru, 2026). It delivers those answers into tools people already use, such as Slack and the browser.
Best for: support, sales enablement and HR teams where the risk is a wrong policy answer, and where someone can own the content and keep it verified.
Where it falls short for an operator without a data team: Guru governs written knowledge. It is the right home for "what is our refund policy," and the wrong home for "what is our current loss ratio on this program." It also depends on content owners doing the verification work, which takes real time from your experts.
6. Coveo: best for large enterprises adding AI search to customer channels
Coveo describes itself as "The AI Relevance Platform," with products for AI commerce, AI service, AI website and AI workplace. The workplace product promises unified answers from every system and source, personalized by role, location and intent (Coveo, 2026).
Best for: enterprises that want one relevance engine behind their ecommerce search, customer self-service and intranet, and have the team to tune it.
Where it falls short for an operator without a data team: Coveo's center of gravity is customer-facing search at enterprise scale. For a mid-market firm that wants an internal assistant or operational agents, it is more platform than you need, and implementations of this kind typically involve technical staff or a partner.
How to choose: three questions
Where do your hardest questions live? If the answer is "in documents, wikis and chat," pick a search tool: Microsoft 365 Copilot if you are a Microsoft shop, GoSearch for a self-serve start, Onyx for self-hosting, Guru for verified answers. If the answer is "in our ERP, our property management system, our policy admin platform, our billing system," you need something that models that data. That is what OC builds.
Do you want answers or finished work? Search returns information and a person does the work. Agents draft the triage note, flag the missing document or reconcile the numbers, and a person approves. Count the work items you want handled each week (submissions triaged, invoices matched, deals screened). That count is the unit to measure any tool against.
Who will run it? Every self-serve tool needs an owner for connectors, permissions and content. If you have that person, self-serve saves money. If you do not, a delivered option is cheaper than a tool nobody maintains. We wrote more about that trade-off in buy vs build for an AI context layer and why AI pilots stall before they hit EBIT.
Our opinion, for what it is worth: a lot of mid-market operators shopping for Glean alternatives do not need better search. They need their systems to agree with each other. Search on top of systems that disagree just finds the disagreement faster.
Frequently asked questions
Is there a cheaper Glean alternative for a 75 to 150 person company?
Yes. Microsoft 365 Copilot Business is sold for up to 300 users as an add-on to a qualifying Microsoft 365 plan, GoSearch offers a free start, and Onyx is open source if you can host it. Glean does not publish pricing, and third-party guides report a roughly 100-seat minimum (GoSearch, 2026), so smaller firms should confirm terms directly with Glean.
Which Glean alternative can answer questions from our ERP as well as our documents?
Most Glean alternatives are workplace search tools built around documents, wikis and chat. OutcomeCatalyst connects ERP, CRM, property management, policy admin and EHR and billing systems into one knowledge graph, so answers come from the records themselves. Microsoft 365 Copilot can reach other systems through custom connectors and agents, but someone has to build them.
Do we need a data team to run OutcomeCatalyst?
No. OC is delivered and run by our team. We connect your systems, build the brain, train the agents and operate them. Your people review and approve agent work, and they tell us when an agent decides differently than they would.
Do you copy our data into a new warehouse?
No. OC builds a governed context layer over the systems you already run. Your ERP, CRM and other systems stay the systems of record. See what an AI context layer is for how that works.
Can OutcomeCatalyst connect to our specific systems, like DealCloud or our billing platform?
OC connects the systems mid-market operators run, including CRM, ERP, practice and billing systems, documents and spreadsheets. Whether a specific product connects directly or through exports is something we confirm in the first scoping call, system by system, before any commitment.
When is Glean the better choice?
When your main need is fast, permission-aware search across many workplace apps such as Google Drive, Slack, Confluence and Jira, and you have the budget and seat count for an enterprise contract. Glean lists 275+ connectors and has deep experience in exactly that problem.
What are your security and compliance standards?
OutcomeCatalyst is HIPAA-aligned and SOC 2 Type 2 aligned, with the formal audit underway and expected to complete before year-end.
