FAST CAPTURE
Type a thought and hit send. No folders, no setup, no friction. New ideas land in your Inbox first, so you can capture now and organise later.
NATURAL BRANCHING
Tap any idea to drill deeper and add child branches. Start from one seed and grow it into a full mind tree as your thinking expands.
VISUAL THINKING
Use Tree Map view to see your idea structure at a glance. Pinch, zoom, and pan through your thinking visually. Long-press any node to edit, move, or delete.
SEARCH AND ORGANISE
Find any idea quickly with text or tag search. Filter by Top Level, Seedbed, Recent, Most Branched, or Deep Ideas. Pin the ideas you want to keep in focus.
EXPORT AND SHARE
Turn any idea tree into a beautifully formatted PDF. Share it with your team, send it to yourself, or archive your thinking for later.
PRIVATE AND OFFLINE
Everything stays on your device. No account. No cloud. No forced sync. Light and Dark Mode are both supported, with six accent colours to personalise your trees.
