FLEECE / AI BRAINSame promise. Different physics.
Cloud workspaces, enterprise search and wiki tools all promise your company one memory. Only one keeps that memory on your machines — mapped, metered and open to every AI app you use.
Fleece AI Brain is the local-first alternative to cloud knowledge tools: your company's knowledge lives as plain Markdown and SQLite on your own machines, syncs in from 20 tools, serves every MCP-compatible AI app, and shows what each AI agent does and costs. These pages compare it, criterion by criterion, with the tools teams usually shortlist.
Fleece AI Brain vs Notion
Cloud workspace vs local-first AI memory — where should company knowledge live?
→Fleece AI Brain vs Obsidian
Same .md files, same local-first values — plus connectors, AI and team access. Keep your vault, add a brain.
→Fleece AI Brain vs Glean
Enterprise search rollout in a vendor cloud vs local-first AI memory you set up in minutes.
→Fleece AI Brain vs Guru
Verified cards in the cloud for people vs open files your AI agents actually read.
→How to read these comparisons
Every page here follows the same shape: a verdict in the first paragraph, a ten-criterion table you can scan without reading prose, three narrow cases where the other tool is genuinely the better pick, and the questions teams actually ask us during an evaluation. No page hides the trade-off — a comparison you cannot trust is a comparison you cannot use.
The criteria are the ones that change the outcome a year in, not the ones that demo well: where the data physically lives, whether the format outlives the vendor, how knowledge gets in and stays current, which AI apps can read it, whether agent activity and cost are visible, and what happens on the day you stop paying.
Before you shortlist
What is the main difference between Fleece AI Brain and a cloud knowledge tool?
Where the knowledge lives. Notion, Glean and Guru keep your company's memory on their servers and rent you an interface to it. Fleece AI Brain keeps it as plain Markdown and SQLite on your own machines, syncs your tools into it, and serves it to every MCP-compatible AI app. You can stop paying and still open every file.
Is Fleece AI Brain a replacement for Notion or Confluence?
For the knowledge your AI needs to reason over, yes — the Notion connector imports your workspace and keeps syncing it. For collaborative editing, databases and project surfaces, teams usually keep their existing tool and let the Brain sync from it. The two are not mutually exclusive.
How is this different from enterprise search like Glean?
Enterprise search indexes your tools and answers questions about them. The Brain builds a typed graph you own — agents, tools, people, decisions — that any AI app can both read and write. Search gives you retrieval; the graph gives you retrieval plus a durable, inspectable memory that accumulates.
We already use Obsidian. Does that make this redundant?
The opposite: the vault format is Obsidian-compatible, so the same folder opens in Obsidian. What the Brain adds on top is the syncing connectors, the MCP server that lets every AI app query the vault, and per-agent cost and activity — the team layer Obsidian deliberately does not have.
How do we compare these tools honestly?
On your own knowledge, not on feature lists. Start the 14-day trial, point the connectors at the tools you actually use, ask all the candidates the same five questions your team asks each week, and judge the answers and their provenance.
What does Fleece AI Brain cost compared to these tools?
Solo is €12 per month, Pro €24, Teams €49 per user per month, and the local brain is free forever. Every plan starts with a 14-day trial, cancel anytime.
