What makes it different

Write your way

Dual-view editing
WYSIWYG & Markdown, together

Toggle between a rich formatted view and raw markdown—or open both side by side. Mia doesn’t force a choice. Edit how you think.

Knowledge graph
Wiki links that just work

Type [[ to link any document in your workspace. Search by name, create new files on the fly, and build a personal knowledge base without leaving the editor.

01
Split-view editing

Open two or more documents side by side. Write one document while referencing another, without switching tabs.

02
Five typography modes

Switch between Sans, Serif, Handwritten, Monospace, and Slab fonts. Your editor, your feel.

03
File explorer & tabs

Sidebar directory navigation, tab-based multi-document editing, and recently opened files. Files open as native OS associations.

04
Code & image support

Syntax highlighting for 25+ languages. In-editor image viewing for PNG, JPEG, GIF, WebP, SVG, and more.

05
Todo panel

A floating todo panel tracks tasks created via wiki links. Check them off, jump to the linked file, or remove them—without leaving your document.

06
Native & fast

Built with Tauri for true native macOS performance. Opens instantly, handles large vaults, and integrates with OS file associations.
