The free, local-first Notion alternative - with built-in AI
NoteBrain is a Notion alternative for people who want their notes on their own machine, not on someone else’s server. Where Notion keeps every page in its cloud as proprietary blocks, NoteBrain’s free desktop app stores notes as plain files on your disk and can run AI locally - no account, no metering. Free forever, with an optional managed Cloud plan when you want sync and AI that just work.
The pricing, straight (June 2026). Notion bundles full AI only on its Business plan (€19.50/seat/mo, billed annually); Free and Plus get a capped AI trial. NoteBrain gives you free local AI, free bring-your-own-key, and managed cloud AI from 3€/mo - or sync and AI together from 4€/mo.
Two flavours, clearly different from Notion’s cloud-only model. The free Desktop app (macOS, Windows, Linux) stores notes as plain files on your disk and can run Ollama locally for offline AI. The free Web app at app.notebrain.ai keeps notes in your browser’s IndexedDB and uses cloud AI (keyword search only, no local Ollama). An optional Cloud subscription (sync + AI from 4€/mo) adds managed cross-device sync and server-side AI.
Why people choose a local-first Notion alternative
- Your data on your machine. On the desktop app, notes are plain files on your disk - not rows in a database you can’t see. Stop the platform, keep your notes.
- Private, local AI. Point NoteBrain at a local Ollama model and your prompts never leave your computer, or bring your own Gemini / OpenAI / Claude key - free. Notion’s AI is server-side and metered.
- Native whiteboard, mindmap & gantt. Notion has no native canvas or mindmap; NoteBrain ships an Excalidraw canvas, native mindmaps and a native gantt out of the box.
- Fully offline on desktop. The desktop app - including local AI, hybrid search and audio transcription - works with no connection. Notion added offline in 2025, but it’s partial: only the first 50 rows of a database download, and AI blocks, embeds and forms don’t work offline.
- EU / GDPR by default. Operated by StarObject S.A. in Luxembourg; no third-party trackers in the app.

When Notion is the better choice
We’d rather you pick the right tool than the wrong one. Notion is the stronger choice if your team co-edits all day or lives in relational databases. It has mature real-time multi-user collaboration - simultaneous editing, inline comments, mentions, guest sharing and team spaces - plus databases with relations, rollups, formulas and 10+ views, published Notion Sites, AI agents that reach into Slack / GitHub / Google Drive, polished native mobile apps, always-on cloud sync free on every plan, and a huge template and integration ecosystem. If those matter more to you than local files and private AI, Notion is the better fit.
What carries over from Notion
Export your Notion workspace to Markdown & CSV, then drag the unzipped folder into NoteBrain - pages and sub-pages come across. Note that Notion databases, relations and rollups don’t round-trip cleanly through Markdown/CSV, so very database-heavy workspaces will need some cleanup.
FAQ
Is NoteBrain really free?
Yes. The web app and the desktop app are free forever, with no row, block or page limits. Paid plans only exist for managed cloud AI (from 3€/mo) and cross-device sync (from 4€/mo) - both optional. Local Ollama and your own API keys are always free.
Can I import my Notion workspace?
Yes. Export your Notion workspace to Markdown & CSV, then drag the unzipped folder into NoteBrain. Pages and sub-pages come across; Notion-specific databases, relations and rollups may need cleanup.
Does Notion work offline?
Partly, since 2025: the Notion desktop and mobile apps can open pages offline on all plans, but it’s limited - only the first 50 rows of a database download, and AI blocks, embeds and forms don’t work offline (the web browser is excluded). NoteBrain Desktop works fully offline, including local AI and search.
Does AI cost extra?
Only managed cloud AI does (from 3€/mo). Local Ollama and your own Gemini/OpenAI/Claude key are unlimited and free on every plan.
