Glean Alternatives in 2026
Published 2026-07-18 · Facts last verified 2026-07-18
The best Glean alternative depends on what you actually need: Luffy if you want an AI coworker in Slack that does the work, not just finds it; Onyx if you want open-source enterprise search you can self-host; Dust if you want to build custom agents; Microsoft 365 Copilot if your company lives in Microsoft tools.
| Product | What it is | Best for | Pricing |
|---|---|---|---|
| Luffy | An AI coworker that works inside Slack, connects to 900+ tools, and ships completed work: reports, dashboards, follow-ups, research, and automations with workspace memory. | Teams on Slack who want work done, not just answers found. | Monthly work budget that scales with usage (see luffy.so/pricing). |
| Onyx | Open-source (MIT) AI chat and enterprise search that connects to company docs and tools; ~20k GitHub stars; cloud or self-hosted. | Teams that want Glean-style search with self-hosting and code-level control. | Open-source self-host is free; cloud and enterprise tiers exist. |
| Dust | A platform for building custom AI agents that collaborate with people across company data and tools ("multiplayer AI"). | Teams that want to design their own agents per workflow. | Per-seat SaaS pricing with a free trial. |
| Microsoft 365 Copilot | Microsoft’s assistant embedded across Word, Excel, Outlook, and Teams, grounded in your Microsoft 365 data. | Organizations standardized on Microsoft 365. | Per-seat add-on to Microsoft 365 licensing. |
When to choose each
- Luffy: Choose Luffy when the bottleneck is recurring work — weekly reports, enrichment, follow-ups — rather than finding documents.
- Onyx: Choose Onyx when data-residency or open-source control matters more than a managed experience.
- Dust: Choose Dust when you have the appetite to build and maintain agent configurations tailored to each team.
- Microsoft 365 Copilot: Choose Copilot when your documents, mail, and chat already live entirely inside Microsoft 365.
Frequently asked questions
- Is Luffy a direct Glean alternative?
- Partially. Glean is enterprise search: it finds and answers from your documents. Luffy is an AI coworker: it connects to your tools from Slack and produces work — reports, follow-ups, automations. If your goal is "find things," compare Glean with Onyx; if it is "get work done," that is Luffy’s category.
- What is the difference between enterprise search and an AI coworker?
- Enterprise search retrieves and summarizes what exists. An AI coworker takes actions: it drafts the report, updates the sheet, sends the follow-up, and remembers how your team works. Retrieval is a feature of an AI coworker; it is the whole product for enterprise search.
- Which Glean alternative can be self-hosted?
- Onyx is open source under the MIT license and can be self-hosted. Luffy, Dust, and Microsoft 365 Copilot are managed services.
- Does Glean publish pricing?
- As of July 2026, Glean does not publish pricing on its website; quotes come through sales. Among alternatives here, Onyx self-hosting is free, and Luffy and Dust publish their pricing models publicly.
