Glean alternatives

Test it on the messy stuff.

Every vendor demo runs on clean data. Your firm doesn't. Bring 10 real questions and your worst folders, and score us against Glean.

Bring your messy stuff
Tricky Wombat cross-department search

The right Glean alternative depends on where your knowledge lives and how you want to roll out. Microsoft 365 Copilot fits Microsoft-first companies. Guru fits teams that need expert-verified answers. GoSearch fits teams that want self-serve setup. Onyx fits teams that must self-host. Tricky Wombat fits teams with complex questions whose answers are spread across many sources, and it runs alongside any of them.

Glean is built to roll out across a whole company. Buyers typically commit to 100 to 250 users or more on a multi-year contract (Vendr), and it takes about four to five weeks to get useful answers. That works if you are ready to change how everyone in the company searches. If you want answers for one team or one client project first, a smaller tool you can start this week is a better fit.

The five alternatives below each fit a different situation. The table compares them with Glean on eight criteria. Each profile after it explains the situation where that product wins, including the situations where Tricky Wombat is the wrong pick.

Two ways to roll out AI search: company-wide with 100 to 250+ users, a multi-year contract and 4 to 5 weeks to answers, or project by project with one team, live in 24 hours, expanding when it works.

Test it on the messy stuff

Every vendor demo runs on data the vendor chose. Your data has duplicate files, stale drafts and three versions of the same rate card. Accuracy on that data is the only number that predicts whether people keep using the tool after month two.

Where you run the test matters as much as what you ask. Glean's free trial runs in a sandbox with sample data. A Tricky Wombat pilot runs on your live data, with no fee for 14 days.

Run the same test on your two finalists:

  1. Collect 10 questions your staff asked in the last month. Include at least 3 that need facts from more than one source.
  2. Connect the same sources to both tools with the same permissions.
  3. Score every answer as correct and cited, correct but uncited, wrong, or no answer.
  4. Count confident wrong answers on their own line. A confident wrong answer costs more than no answer, because someone acts on it.

Tricky Wombat publishes the seven points where retrieval pipelines fail. Use the list as a scoring checklist for any vendor, including this one.

Pilot scorecard: collect 10 questions, connect the same sources, and score each finalist on correct and cited, correct but uncited, wrong, and no answer.

Why do companies look for a Glean alternative?

Most teams that search for a Glean alternative already agree on the goal: one place to ask a question and get a sourced answer from company data. The disagreement is about how to get there, not the idea.

Teams usually start looking for one of three reasons. The first is scope. Glean is sold to whole companies, often starting at 100 users or more. Many firms would rather try AI search with one team or one client project first, and roll it out to everyone once it works.

The second is overlap. If your company already runs on Microsoft 365, Copilot sits inside the tools your staff open every morning, and a second search layer has to earn its place.

The third is control. Some security teams require the index to run on servers they own, which points toward an open-source option.

Each situation has a different winner. A single ranked list hides that, so the profiles below sort the alternatives by the situation each one wins.

Three reasons teams look for a Glean alternative and the winner for each: scope favors Tricky Wombat, overlap with Microsoft 365 favors Copilot, and control over where the index runs favors Onyx.

Is Tricky Wombat right for you?

Tricky Wombat is built for companies with 500 to 2,000 employees, where the answer to one client question often sits in three places: a proposal in Sales, a method in Delivery and a contract clause in Legal. Retrieving the closest-matching document is the easy part. Assembling the right context from all three is where answers go wrong. Tricky Wombat runs every question through a seven-step pipeline (query rewriting, GraphRAG, semantic analysis, clustering, reranking, statistical document selection and statistical chunking) before a model writes a word. The design follows one thesis: answer quality depends far more on the context a model receives than on which model you choose.

The rollout matches how professional firms work. You deploy Tricky Wombat one project at a time, next to whatever search tool you already use. Once your documents are available, a project is up and answering questions within 24 hours, and the engineers who built the pipeline run onboarding themselves, with no implementation partner in between.

Tricky Wombat is the wrong pick in two cases. If you want one platform that replaces every search tool across the company in a single rollout, Glean or Copilot is built for that. And the company runs a deliberately small, invite-only onboarding queue, so you may wait for a slot.

Choose it over Glean if your hardest questions draw on many sources, you want to start with one project instead of the whole company, and you want a pilot on your own data before you sign an annual contract.

One question pulls a Sales proposal, a Delivery engagement method and a Legal contract clause through the Tricky Wombat context pipeline into one answer with three citations.

Which other Glean alternative fits your team?

Each of these four wins a different situation. Pick the card that sounds like your company.

Microsoft 365 Copilot

Best for companies that already run on Microsoft 365

Copilot wins on proximity. It sits inside Outlook, Teams, Word and Excel, so adoption starts in the apps your staff already use. Microsoft dropped its 300-seat minimum in January 2024, so you license Copilot user by user. More than 100 prebuilt connectors extend search beyond Microsoft data, and Microsoft released 35 new connectors in February 2026.

Copilot draws most of its answers from your Microsoft 365 tenant. If your documents live in Google Drive, Box, Confluence and a practice-management system, confirm a connector exists for each source before you compare it with a dedicated search product.

Choose it over Glean if most of your knowledge sits in SharePoint, OneDrive and Teams and you want one vendor for productivity software and AI.

Guru

Best for support and revenue teams that need verified answers

Guru wins where the same questions come up every day and a wrong answer reaches a customer. Subject-matter experts own the knowledge and verify it on a set schedule, and Guru's knowledge agents return cited answers that respect source permissions. Guru supports GxP compliance, which matters to life sciences teams, and connects to more than 100 tools.

Guru's model centers on curated knowledge that people maintain. If most of your answers live in raw documents nobody curates, test that content during the trial.

Choose it over Glean if your frontline teams answer repeat questions and you want named experts to own every answer.

GoSearch

Best for teams that want self-serve setup

GoSearch lets a team sign up and connect its own apps without a sales cycle. It lists more than 100 integrations and lets Enterprise customers bring their own AI model. GoSearch states that setup takes minutes.

Because you sign up and connect apps yourself, one team can try it on a few tools before bringing in IT or procurement.

Choose it over Glean if you want a like-for-like replacement you can stand up yourself, without a long sales cycle.

Onyx

Best for teams that must self-host

Onyx, formerly Danswer, publishes its Community Edition under the MIT license. Your team runs the full search stack on its own infrastructure and connects the model of its choice. The project has more than 32,000 GitHub stars and 50+ connectors, and its Enterprise plan adds SSO and on-premise deployment.

Self-hosting moves operations work to your team: upgrades, connector maintenance and uptime all become yours.

Choose it over Glean if company data must never leave your network, or if you have engineers who want to own the stack.

Can you run Tricky Wombat alongside Glean or Copilot?

Yes. Tricky Wombat does not ask you to replace anything. You deploy it one project at a time, connect only the sources that project uses, and give access only to the people on it. Your company-wide search tool keeps doing its job for everyone else.

The split works because the two jobs differ. Glean, Copilot and GoSearch answer the everyday question well: where is the travel policy, who owns the Q3 deck. A client engagement asks harder ones. What did we recommend to a similar client in 2024, which contract terms did Legal reject, and how did Delivery scope the last three projects like this one? Those answers are spread across many sources, in drafts and PDFs a company-wide index treats as equal. A project-scoped deployment tunes retrieval to one engagement's documents and vocabulary.

In practice, a firm starts with one practice group or one high-stakes engagement. Once that team's documents are available, Tricky Wombat is answering its questions within 24 hours. When the project ends, you retire the deployment or point it at the next one, and nothing in your existing stack changes. Teams inside larger companies use the same approach, which is why Tricky Wombat for small teams runs on the same pipeline as the enterprise product.

A company-wide search tool answers everyday questions for everyone while Tricky Wombat runs next to it for one project team, live within 24 hours and retired or redeployed when the project ends.

How quickly can you start getting answers?

The sooner a pilot starts, the sooner you know whether a tool works for your team. Mid-sized companies typically see first results from Glean after four to five weeks, according to the Glean Community. With Tricky Wombat, you are asking questions within 24 hours once your documents are available. GoSearch says setup takes minutes for connected apps. Onyx says its self-hosted installer deploys in minutes. Copilot can take up to 24 hours to appear once licenses are assigned, after data-readiness work. Guru does not publish a timeline.

Connecting your files is the quick part. Getting answers your team trusts takes tuning. Before you sign, ask each vendor three questions: Who does the tuning? How much of your team's time will it take? How will you measure success at the end of the pilot?

How should you choose a knowledge base vendor?

Start with the questions your team asks every week. Some are simple lookups, like the travel policy or the latest rate card. Almost any tool on this page handles those. Others need facts from more than one team, like what you proposed to a similar client last year. Those harder questions are where tools differ, so give them the most weight.

Next, look at your documents and how you want to roll out. If experts keep your answers up to date, a tool built around verified content works well. If your knowledge sits in years of proposals and contracts that nobody curates, the tool has to find the right answer on its own. Then decide whether you want to launch for everyone at once or start with one team.

Those answers usually point to a clear choice. If you run on Microsoft 365, start with Copilot. If experts own the answers your teams repeat all day, look at Guru. If your data must stay on your own servers, look at Onyx. If you want to set it up yourself today, try GoSearch. If your hardest questions need answers pieced together from many sources and you want to start with one project, try Tricky Wombat.

Finally, test before you commit. Run the same pilot on your top two choices with your own questions and documents. Watch for answers that sound confident but are wrong. Check that people only see answers from files they are allowed to open. Then pick the tool your team trusts, and start with a short contract.

FAQ

Frequently asked questions

The best Glean alternative depends on your situation. Microsoft 365 Copilot fits companies already on Microsoft 365. Guru fits teams that need expert-verified answers. GoSearch fits teams that want self-serve setup. Onyx fits teams that must self-host. Tricky Wombat fits teams with complex questions whose answers are spread across many sources, and it runs alongside any of the others.

Yes. Tricky Wombat deploys one project at a time and connects only the sources that project uses, so it runs next to Glean, Copilot or any other company-wide search tool. Teams keep their existing search for everyday lookups and use Tricky Wombat for complex questions whose answers are spread across many sources.

Yes. Onyx, formerly Danswer, publishes its Community Edition under the MIT license. You host it on your own infrastructure, connect your own language model and choose from 50+ connectors. Its Enterprise plan adds SSO and on-premise deployment for teams that want vendor support.

Copilot replaces Glean for companies whose knowledge lives mostly in Microsoft 365. It runs inside Outlook, Teams, Word and Excel and includes more than 100 prebuilt connectors. Companies with large document sets in Google Drive, Confluence or industry systems should confirm connector coverage for each source first.

For companies with 500 to 2,000 employees, look for a tool you can start with one team and test on your own data. Tricky Wombat is built for this size, deploys project by project and is running within 24 hours once your documents are available. Copilot fits mid-sized companies that run on Microsoft 365.

Switching time depends on how many sources you connect and who tunes retrieval. Glean's community reports four to five weeks to first value for mid-sized companies. Tricky Wombat runs a first project within 24 hours once the documents are available. Running a new tool next to Glean for one project avoids a hard cutover.

Elastic is a platform for building search, not a ready-made employee search app. Elastic deprecated its standalone Workplace Search product with version 9.0. It suits engineering teams that want to build and maintain their own search experience on top of Elasticsearch.

Chatbase answers a different need. It builds customer-facing support chatbots, while Glean searches internal company knowledge for employees. If you need both, check whether one product covers both jobs. Every Tricky Wombat plan includes a customer-facing chatbot alongside internal search.

Start at least 90 days before your Glean renewal date, and check your contract for its renewal notice period. A 14-day pilot on your own data, plus two to four weeks of procurement and security review, fits inside that window and gives you a real comparison before the renewal decision.
