Write in plain Markdown, alone or with your team.
Lydie is a lightweight writing app for the web and desktop. Open a folder of Markdown files, or share a workspace and edit together in real time.
No account needed. Your documents stay in your browser until you sign in to sync.
What Lydie does
Your files stay plain Markdown
Point Lydie at a folder and it edits the files in place. There is no import and no special format. The same folder still opens in Obsidian, your code editor or git.
Fast like a native app
Your workspace lives in a database on your device. Opening, switching and searching documents does not wait for a server, and it all works offline.
Works for teams when you want it
Create a hosted workspace to write with others in real time, in the same editor. Folder workspaces stay on your machine and never touch our servers.
Built for agents
Everything you can do in the app is also an API call, an MCP tool and a CLI command. Agents use the same actions you do, with the same permissions.
The Lydie app is open source under the AGPL-3.0. The hosted service behind team workspaces is not. Open the full app.
