Project Notes
These are the basics. When you’re ready, unlock more.
Everything you need. Nothing extra.
Fast, focused, and designed to get out of your way.
Start Simple
Mudlark starts you with 8 intuitive symbols. When you’re ready for more, long-press the lock icon to unlock the full set — numbered lists, code, math, timers, and more.
Quick Capture
Jot something down from anywhere with a keyboard shortcut, or automate it with the mudlark:// URL scheme. Your thought goes straight to your note without switching windows.
Dual-Pane View
Write freely on the left. See your notes cleaned up and organized on the right. Two sides, one document.
15 Themes
From Paper to Tokyo Night, Solarized to Catppuccin. Pick from seven light and eight dark themes, each with its own color palette.
Math & Timers
Do quick math right in your notes. Convert between units like km to miles. Set countdown or looping timers to stay on track.
Export Everywhere
Auto-export to Obsidian, Logseq, iA Writer, Bear, Drafts, or Apple Notes. Or just copy to the clipboard.
Ephemeral by Design
Mudlark is where thoughts start, not where they live forever. Capture fast, organize later, move on when ready. Auto-cleanup is built in.
Choose your canvas.
15 themes with hand-picked colors. Each one gives your notes a different look and feel.
The starting point, not the destination.
When your notes are ready to live somewhere permanent, send them to your favorite app.
