Text-first input
Write quickly and stay focused on the structure of your ideas, not decoration or formatting.
Local-first structured thinking app for iOS
Structure your thoughts into worlds, pyramids, and trees.
Structree helps you turn messy ideas into clear structures through three thinking spaces: World, Pyramid, and Tree. Text-first, image-supported, and fully stored on your device.
No login. No cloud account. No unnecessary external communication.
Structree
Local
Product idea
Clarify the purpose, audience, and structure before building.

User problems
Input friction
Cognitive load
Next structure
Break down, connect, and refine your thinking step by step.
Concept
Not just notes. A place to shape your thinking.
Structree is designed for moments when a blank note is too flat, a mind map is too free-form, and a project tool is too heavy.
Optional images
Add images only when they support your thinking. The main experience remains simple and lightweight.
Built for iOS
Designed as a focused mobile workspace for organizing thoughts whenever ideas appear.
Three spaces
Choose the structure that matches your idea.
Different thoughts need different shapes. Structree gives you three simple pages for organizing broad contexts, layered logic, and branching relationships.
01
World
Capture broad ideas, contexts, and related elements in one thinking space.
02
Pyramid
Break a concept into layers so the logic becomes easier to understand.
03
Tree
Grow ideas through connected branches and clarify relationships over time.
Your thoughts stay with you.
Structree works entirely on your device. It does not require an account, a cloud workspace, or unnecessary external communication. It is built for private thinking.
✓No login required
✓No cloud account
