# 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.

## The options

### 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.

- **Best for:** Teams on Slack who want work done, not just answers found.
- **Pricing:** Monthly work budget that scales with usage (see luffy.so/pricing).
- **When to choose:** Choose Luffy when the bottleneck is recurring work such as weekly reports, enrichment, and follow-ups rather than finding documents.

### Onyx

Open-source (MIT) AI chat and enterprise search that connects to company docs and tools; ~20k GitHub stars; cloud or self-hosted.

- **Best for:** Teams that want Glean-style search with self-hosting and code-level control.
- **Pricing:** Open-source self-host is free; cloud and enterprise tiers exist.
- **When to choose:** Choose Onyx when data-residency or open-source control matters more than a managed experience.

### Dust

A platform for building custom AI agents that collaborate with people across company data and tools ("multiplayer AI").

- **Best for:** Teams that want to design their own agents per workflow.
- **Pricing:** Per-seat SaaS pricing with a free trial.
- **When to choose:** Choose Dust when you have the appetite to build and maintain agent configurations tailored to each team.

### Microsoft 365 Copilot

Microsoft’s assistant embedded across Word, Excel, Outlook, and Teams, grounded in your Microsoft 365 data.

- **Best for:** Organizations standardized on Microsoft 365.
- **Pricing:** Per-seat add-on to Microsoft 365 licensing.
- **When to choose:** Choose Copilot when your documents, mail, and chat already live entirely inside Microsoft 365.

## FAQ

### 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 reports, follow-ups, and 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.
