Fleece AI Brain vs Glean: skip the rollout, own the knowledge
Glean is enterprise AI search you buy through demos and quotes, indexing your apps into its cloud. Fleece AI Brain is local-first memory you set up yourself in minutes, on your own machines, open to every AI app. Here is the comparison.
Fleece AI Brain is the strongest Glean alternative for teams that want enterprise-grade AI knowledge without an enterprise rollout. Glean indexes your apps into its own cloud, sold through demos, quotes and deployment projects, surfaced in one assistant. The Brain installs in minutes at €12–49, keeps knowledge on your machines, opens to any MCP app like Claude and Cursor, and tracks what each agent costs.
A managed search cloud. A brain you actually own.
Glean is a capable enterprise AI search and work assistant, aimed at large companies. It connects the apps your organization runs, indexes them into Glean's own cloud, and answers questions and automates work inside its assistant surface. That power arrives through an enterprise motion: demos, quotes, security review, an admin-led deployment and a rollout project — and the resulting index of your company's knowledge lives in the vendor's infrastructure.
Fleece AI Brain reaches a similar outcome — one place your AI can answer from company knowledge — from the opposite direction. You install a desktop app, sign in to the tools you use through 20 built-in connectors, and each one syncs directly from the provider to your device; the knowledge stays in plain Markdown and SQLite on your machines rather than in another vendor cloud. There is no sales call and no rollout: a trial starts in minutes, and plans run €12 to €49.
The deeper difference is openness and visibility. Instead of one proprietary assistant, the Brain serves your knowledge to any Model Context Protocol app — Claude Desktop, Cursor, Cline, Zed, your own agents — with citations, and the Teams plan maps your whole AI organization and tracks what every agent costs, something a managed search product does not set out to give you.

Choose Fleece AI Brain if…
- +You want enterprise-grade AI knowledge without an enterprise rollout — a trial starts in minutes, with public €12–49 plans and no sales call.
- +Company knowledge must stay on your machines: the vault is plain files, connectors sync provider to device, and nothing transits our servers.
- +You want any AI app to answer from it — Claude Desktop, Cursor, Cline, Zed, your own agents over MCP — not a single proprietary assistant surface.
- +You need to see and control AI cost: the org map shows every agent, what it touches, and what it spends.
- +You refuse lock-in: your knowledge is Markdown and SQLite you can open anywhere, not an index inside a vendor's cloud.
Where Glean still makes sense
- ·You are a very large organization that specifically wants a fully managed SaaS search rollout with vendor hand-holding through deployment.
- ·Your procurement requires an enterprise contract, a dedicated assistant surface and vendor-run indexing of every internal app.
- ·In those cases the Brain still fits many teams inside the same company who want local-first, MCP-open memory without waiting on a central rollout.
You don't need a rollout — just sign in
There is no deployment project to schedule. Start the 14-day trial (no card), connect the tools you already use with one OAuth sign-in each, and plug Claude or Cursor in over MCP. Within minutes your AI is answering from company knowledge that never left your machines — and if it isn't for you, there is no contract to unwind and no vendor index to reclaim.
Frequently asked questions
Is Fleece AI Brain a good alternative to Glean?+
Yes — it is the strongest alternative for teams that want enterprise-grade AI knowledge without an enterprise rollout. Glean indexes your apps into its cloud through a sales motion; the Brain is self-serve at €12–49, keeps knowledge on your machines, opens to any MCP app, and tracks per-agent cost.
Do I have to go through a sales process?+
No. Where Glean is bought through demos, quotes and an admin-led deployment, the Brain is self-serve: you download the desktop app, start a 14-day trial without a card, and connect your tools yourself. Public plans run €12, €24 and €49.
Where does my company's knowledge live?+
On your own machines. The vault is plain Markdown and a SQLite index, and each of the 20 connectors syncs content directly from the provider to your device. Nothing is indexed into Fleece's cloud, and we can't read your data — optional cloud sync is end-to-end encrypted.
Which AI apps can use it?+
Any app that speaks the Model Context Protocol — Claude Desktop, Cursor, Cline, Zed and your own agents — connected with one copy-paste, and answers cite their sources. Instead of a single proprietary assistant, your knowledge is open to the whole AI stack you already use.
Can the Brain scale to a whole company?+
Yes. The Teams plan gives the organization one shared brain with role-based access, SSO and an audit log, plus an AI organization map showing every agent, tool and person — and what each agent costs — without a central rollout project.
Does the Brain track what our AI costs?+
Yes, and it is a core differentiator. The Teams plan meters cost per agent across your organization map, so you can see which agents run, what they touch and what they spend — visibility a managed enterprise search product does not set out to provide.
What's the lock-in compared with Glean?+
Effectively none. Your knowledge is plain Markdown and SQLite on your own disk, readable by Obsidian or any editor, with or without our app. There is no vendor-held index to migrate out of and, on self-serve plans, no contract to unwind.
How does pricing compare?+
Fleece AI Brain is flat and public: Solo at €12/month with up to 3 connected tools, Pro at €24/month with unlimited connectors, Teams at €49 per user/month with the org map, cost tracking, SSO and audit. Enterprise search is typically an annual contract priced through sales; the Brain's plans stay predictable and self-serve.
