Read once, map as you go.

Most reading apps give you a pile of highlights. Most mind map apps have no idea what you're reading. App puts both in one place: you read, you highlight, and the map grows underneath you — no app switching, no "I'll organize this later."

HOW IT WORKS

1. Add a document. Paste in an article, a chapter, your own notes, or type it out fresh.
2. Read it your way. Scroll at your own pace, or switch to RSVP mode and let the words come to you, 200–600 words per minute.
3. Highlight what matters. Select any phrase and capture it. It becomes a node on your map — and it keeps a link back to the exact passage it came from, so you can always jump back to the source.
4. Shape it. Tap a node to edit, drag to move it, long-press to link two nodes or nest one under another. Branches form as you think.
5. Find the structure. When loose nodes pile up, Cluster suggests groupings based on the words they share — so a shape emerges from a page full of scattered captures.

COMPARE TWO READS

Pick two or more documents and App shows you which captures overlap and what each one had to itself. Two papers read a week apart, side by side — a connection you couldn't easily have spotted on your own.

EXPORT WHAT YOU MADE

Share any map as a high-resolution PNG image, or as a clean Markdown outline that drops straight into Obsidian, Notion, Bear, or any notes app you already use.

BUILT TO WORK OFFLINE

Everything lives on your device. Reading, capturing, mapping and clustering all run locally — on a plane, on the subway, in airplane mode. No account required, no sign-up wall.

MADE FOR

• Students working through papers and textbook chapters
• Researchers who need the shape of an argument, not 14 disconnected quotes
• Knowledge workers reading long-form essays in short morning blocks
• Anyone who reads to learn and wants something to show for it afterwards

Start with the built-in sample document — it opens with its map and captures already built, so you can see the whole loop in a minute.
