All your knowledge. Always available.
Only you decide where it lives.
Local-First knowledge platform with native local AI and encrypted sync.
💡 We recommend downloading the desktop app: peak performance, 100% offline, and local AI on your device.
Your knowledge, under your control
Four design decisions you won't find bundled together anywhere else.
Truly local-first
Your notebooks live on your disk, encrypted. The cloud is optional and everything works offline.
AI on your machine
Point it at Ollama or LM Studio and run models on your own device. Nothing is sent out, and no per-query cost.
Sync without giving up control
Multi-device sync, end-to-end encrypted. Not even we can read your content.
Open to your workflow
Native MCP server and local HTTP API: connect your notes to Cursor, VS Code or your own scripts.
See Folio from the inside
Editor, canvas, boards, page tree and local AI — all in the same app, with no latency.
Distraction-Free Modular Editor
Write rich content with slash commands (/), 31+ block types, dynamic tables, LaTeX formulas, and instant formatting.
How does Folio work?
No complex setup or required sign-ups. Get started in 3 simple steps:
Create a Notebook
Choose a local directory on your device or drive. An AES-256 encrypted storage space is generated exclusively for you.
Write or import content
Organize pages with block editing, draw on canvas, or import Markdown notes. Connect native local AI to assist you anytime.
Sync or publish whenever you choose
Keep everything 100% offline or enable optional end-to-end encrypted sync to collaborate live and publish web pages in 1 click.
Why switch to Folio?
From cloud dependency frustration to complete data control.
Slowness and cloud dependency
Waiting for pages to load, not being able to work offline, or server outages right when you need to get things done.
Your notes on your disk, opening instantly
Folio saves everything straight to your device. It opens right away, works offline and doesn't rely on any server.
Your data on someone else's servers
Trusting confidential notes, projects and ideas to third-party platforms that can read your content.
Notebooks encrypted on your own device
Your data is stored encrypted on your device. Nobody — not even Folio — can open your notebooks.
Expensive cloud AI subscriptions
Paying monthly fees and sending your private documents to third-party AI services.
AI that runs on your own computer
Summarise and query your notes with local AI models. Nothing is sent out, and you don't pay per query.
Who is Folio for?
A versatile suite tailored for developers, researchers, and creators.
Developers & Technical Teams
Document software architecture, manage product roadmaps, and connect your workspace directly to Cursor or VS Code using the native MCP Server.
Students & Academic Researchers
Take structured lecture notes, summarize research papers with native local AI, and build your personal interconnected knowledge graph.
Creators & Personal Knowledge (PKM)
Manage personal projects, write blog posts, keep daily journals, and publish your pages to the web in just 1 click.
Architected for those who build software
Native to your daily dev workflow. No proprietary lock-in, zero latency, direct IDE integration via MCP, and full data sovereignty.
Everything works even without Internet
Take the test: turn off Wi-Fi or turn on Airplane Mode. Folio never shows loading spinners or locks your notes.
The ultimate study workspace for your academic year
No forced subscriptions, zero ads, and 100% operational in lecture halls without Wi-Fi. Built for lightning-fast note-taking, concept mapping, and private AI studying.
Your semester doesn't need €10/month subscriptions
Folio Local Core is 100% free forever. No course limits, no paywalls, and your notes never get sold or mined.
Take notes at lecture speed
Write directly in clean Markdown with swift keyboard shortcuts. Insert complex LaTeX math formulas without switching apps or losing the professor's explanation.
Matrix Diagonalization & Eigenvalues
• Necessary condition: geometric multiplicity sum equals space dimension.
• If all eigenvalues are distinct, the matrix is immediately diagonalizable.
Everything a student needs in one place
Fast, private, and yours
Your notes live on your device, encrypted
Blocks, notebooks, files and canvases are saved on your disk and encrypted right there. It works with no account and no connection.

No fine print
Folio doesn't run on your data. These are guarantees, not marketing.
“Your knowledge is yours. We don't rent it, train on it or sell it. The cloud is an optional convenience, not the price of using the app.”
Zero telemetry
The app sends none of your notes, audio or activity anywhere. Verify it with a proxy.
AES-256 encryption
The vault is encrypted on your disk and sync is end-to-end. Not even we can read it.
Open where it matters
The data format and protocols (MCP, local API) are inspectable. No black boxes.
Public status
If you use Folio Cloud, server health is public and real-time at /folio/status.
