Your thoughts, truly private
AES-256-GCM encryption protects every note. Vault password plus optional Note Password for extra-sensitive notes. No account, no server, no cloud. Works fully offline.
Multi-modal — every mode, one note
Drawing with native Apple Pencil. Whiteboard for mind maps and flowcharts. Mermaid, tables, LaTeX, and decorations — all native, all in one note.
Your AI, your keys
Bring your own AI — local for privacy, cloud for power. AI generates whiteboards, drafts text, runs semantic search, and acts in your vault through tool calling.
No vendor. No lock-in.
Notes on your own disk, not a vendor's database. Markdown import and export anytime. Bring your own WebDAV server for sync. One app, every major OS.
Beautiful Writing Experience
Multiple header styles (Default / Minimal / Classic / Magazine / Newspaper / Academic) with page presets — Eye Care, Logic Grid, Night Focus — drop cap, and cover images. Every note has its own character.
Whiteboard for Visual Thinking
Mind maps, flowcharts, and diagrams on a zoomable, pannable surface — open right inside any note. Auto layouts (Tree, Layered, Force) clean up a messy board in one click.
Sketch with Native Apple Pencil
Pressure-sensitive, low-latency strokes on iPad. Pencil, marker, and highlighter brushes. Multi-layer composition, fill tool, text boxes, and SVG export — Drawing is a full sketchbook inside your notes.
Decorate Anywhere
Stickers, sticky notes, tape, and stamps — pin to a paragraph or float freely on any note. Drag, scale, rotate, recolor. Encrypted, synced, and rendered in PDF, HTML, and Word exports.
Knowledge Graph
[[WikiLinks]] + ![[Embeds]] build your note network. Hierarchical DAG tags with AI-inferred parent relationships. Interactive graph visualizes how your ideas connect.
Advanced Tables
Formulas (SUM/AVG/COUNT), merged cells, drag-fill, and inline images — data analysis without leaving your notes.
Diagrams & Math
Mermaid diagrams (flowchart, sequence, Gantt, and more) with auto-theming. LaTeX math with a rich symbol panel, inline and block mode, live preview.
