> the OneNote alternative for people who live in Markdown

OneNote is powerful — but it can't render Markdown, keeps your notes in a proprietary format, and its search and sync are famously hit-or-miss. MDflow is a focused, markdown-native workspace that your tools and your AI agents can actually read.

the six things OneNote users complain about

Sourced from years of forum threads and the Microsoft feedback portal — and how MDflow handles each one.

//markdown

Paste `## Heading` and OneNote shows the literal hash marks.

MDflow renders GitHub-Flavored Markdown — write it, see it.

//your data

Notes live in a proprietary .one binary tied to OneDrive.

Every document is a plain .md file you can download anytime.

//sync

OneDrive sync can stall, fail quietly, or need a manual force-sync.

One browser-to-server model; local drafts auto-retry on reconnect.

//search

Search sometimes returns only titles — or nothing — until you clear the cache.

Always-on full-text search with highlighted snippets and folder context.

//consistency

Windows, Mac, web, and mobile behave like four different apps.

One web app — the same experience everywhere, nothing to install.

//agents

No clean way for AI tools to read your notebooks as context.

A remote MCP server + full HTTP API let agents manage your workspace.

$./why-mdflow

why people switch

$mdflow open

Genuinely easy to use

No vault to configure, no ribbon to learn, no plugins to wire up. Open the browser, make a folder, start writing markdown. That's the whole onboarding.

$curl /api/v1

Full API + remote MCP server

A documented HTTP API with full read and write access, plus a remote Model Context Protocol server — so scripts and agents can manage your workspace without running a local server.

$mdflow context

Built for AI agents

Folder descriptions and document metadata give Claude, Cursor, and Codex scoped context. Your notes become a knowledge base agents can actually use.

$mdflow share

Sharing & comments that just work

Publish one document at an unguessable link — readers get a clean rendered page, can comment on a passage, and can clone their own copy. No account needed to read.

Where OneNote is still ahead

We'd rather be straight with you. OneNote is a mature product, and there are real reasons to stay — especially if you depend on these:

Handwriting & the free-form canvas. If you write with a stylus or sketch diagrams, OneNote's ink canvas is excellent. MDflow is text-first Markdown.
Deep notebook hierarchy. Notebooks → sections → pages give three levels of nesting; MDflow uses flat folders by design.
Tags & version history.OneNote keeps page tags and previous versions. MDflow doesn't offer these yet.
Microsoft 365 integration. Tight ties to Outlook, Teams, and the Office suite are hard to beat if you live in that ecosystem.

OneNote alternative — FAQ

Is MDflow a free OneNote alternative?

Yes. The free plan includes 5 markdown files, public sharing, and commenting — no card required. Pro is €4.99/month for unlimited files, 10,000 image uploads, the full HTTP API, and the remote MCP server.

Does MDflow support Markdown that OneNote can't render?

Markdown is the foundation of MDflow. You write in a Monaco-based editor with syntax highlighting and switch between Edit, Split, and Preview — full GitHub-Flavored Markdown, including tables and code blocks.

Can I import my existing OneNote notes?

There isn't a one-click OneNote importer yet. Today you can paste Markdown directly or upload .md files; OneNote exports to Word/PDF, which can be converted to Markdown with open-source tools. A dedicated importer is on our roadmap.

Can AI agents like Claude or Cursor read my notes?

Yes. AI agents can connect directly to MDflow's remote MCP server or use its documented, full-access HTTP API (both on Pro) to read, create, update, organize, share, and delete folders and documents.

Is my content private?

Your workspace requires authentication. Only documents you explicitly share become reachable, via a random, unguessable link, and uploaded images stay private until the document is shared. Sharing can be revoked at any time.

What does OneNote do that MDflow doesn't?

We're upfront about it: OneNote has handwriting and a free-form canvas, three-level notebook nesting, tags, and version history — none of which MDflow offers today. See the “Where OneNote is still ahead” section above.
