Overview

What is SiYuan?

SiYuan is a privacy-first knowledge management and note-taking system, built around a block-based Markdown editor. Presented as a self-hostable alternative to Notion, it combines structured documents, bidirectional links, block references, graph view, databases, tables, code, and mathematical formulas to build a true "second brain".

Content is based on portable Markdown stored locally, avoiding vendor lock-in and facilitating export (Markdown, PDF, HTML). SiYuan is available as a web interface, desktop and mobile apps, with encrypted synchronization to your instance.

DINAO hosts it in France in an isolated container, with encryption, backups, updates, and monitoring — ensuring a sovereign knowledge base where your often-sensitive notes never leave French territory.

Frequently asked questions

You might be wondering…

How does SiYuan differ from Notion?

SiYuan offers comparable block-based editing and bidirectional links, but self-hosted, with data stored in Markdown on your server in France. No proprietary cloud or content lock-in.

Are my notes exportable?

Yes. Content is based on Markdown, exportable to Markdown, PDF, or HTML. You are never trapped in a proprietary format.

Can I use it on mobile and desktop?

Yes. SiYuan offers a web interface, desktop apps (Windows, macOS, Linux), and mobile apps, synchronized with your instance hosted by DINAO.

Are my notes truly private?

Yes. They remain encrypted on your dedicated instance in France, are neither analyzed nor resold, unlike mainstream cloud services.

Can multiple people use it?

Yes, depending on the plan. Team and Enterprise plans support multiple users, with multi-device synchronization for a shared knowledge base.
