Welcome to Zyplus Editor
The open-source markdown editor.
Made with love by Fankrits.
What it does
- •Rich text and raw markdown in the same file
- •Mermaid diagrams and KaTeX math, rendered inline
- •Files stay as
.mdon your disk
No account, no sync, no lock-in.
One editor, every desktop you own
Zyplus ships native builds for macOS, Windows and Linux from a single codebase, so the shortcuts, themes and file handling are identical wherever you write. A workspace is only a folder of markdown, so it moves between machines with a copy, a Git push, or whatever sync you already trust.
macOS

Everything a markdown file can be
Two ways to write
Rich text, or the raw markdown
Write in a WYSIWYG editor when you want the document to look like the document, and drop to plain markdown when you want to see the syntax. It is one file either way — ⌘E switches, nothing converts.
- Milkdown for rich text, CodeMirror for plain
- Per-tab, so two documents can be in different modes
Ships today, with one caveat.
- •Faster startup
Your folders
A workspace, not a database
Point Zyplus at the folders you already keep notes in. The file tree is those folders, the tabs are those files, and your session comes back the way you left it.
- Add as many project folders as you like
- Drag to reorder tabs; unsaved work is marked, never silently dropped
No lock-in
Everything leaves as easily as it arrived
Your notes are already plain .md files on disk, so there is nothing to export in the usual sense. When you do need a copy, it is one menu away.
- Export as .md, or straight to PDF with ⌘P
- Copy the document markdown or its path in one keystroke
Make it yours
Themes for the chrome and the page
Light and dark, plus Catppuccin and Tokyo Night palettes. The theme covers the editor surface you write on, not just the window around it.
- Follows the system theme by default
- Diagrams and code blocks re-color with it
Keyboard first
Every command has a key. Press ⌘/ in the app for the full sheet.

Questions people ask first
- Is Zyplus cross-platform?
- Yes. Zyplus runs natively on macOS, Windows and Linux from the same codebase, so the editor, keyboard shortcuts, themes and file handling behave the same on every machine you use. Builds for all three ship together in every release.
- Does Zyplus work offline?
- Always. Zyplus is local-first: it opens folders on your own disk and never requires an account, a server or a sync service. The only network call it makes is checking for a new release.
- Where are my notes stored?
- In the folders you point Zyplus at, as ordinary .md files. There is no proprietary database or vault format, so the same notes stay readable in any other editor, in Git, or in a plain text viewer.
- Can I move a workspace between operating systems?
- Yes. A workspace is just a folder of markdown files, so copying it to another computer — or syncing it with Git, Dropbox or iCloud — is all it takes to keep writing on a different OS.
- Is Zyplus free and open source?
- Yes. Zyplus is free to download and its source is on GitHub under an open-source license, so you can read it, build it yourself, or fork it.
- Does it support Mermaid diagrams and math?
- Yes. Mermaid diagrams and KaTeX math render inline in the rich text view and re-color with the active theme, and stay as plain markdown code fences in the file.
- How is Zyplus different from Obsidian or Typora?
- Zyplus is open source, has no account or paid sync tier, and treats your existing folders as the workspace rather than importing them into a vault. It also lets you switch any tab between rich text and raw markdown with a single shortcut.
Your notes, your disk
Zyplus stores everything in one folder you choose. Open it in any other editor, back it up however you like, and take it with you if you ever leave.
