Free · In‑App Purchases
Capture ideas, shape them into Thoughts and Trees, and personalize your workspace with illustrated skins designed for iPhone and iPad.
StructMemo is a local-first workspace for capturing thoughts and turning them into clear, navigable structures.
CAPTURE WITHOUT INTERRUPTING YOUR FLOW
Write a Thought as soon as it appears. Voice Capture can turn speech into text, and Smart Naming can suggest a concise title.
ORGANIZE YOUR IDEAS
Review recent Thoughts, search your library, move related items into folders, and elevate them into Upper Structures. Tree lets you move from broad concepts to every detail.
USE SMART GRAVITY WHEN YOU CHOOSE
Smart Gravity can examine eligible Thoughts and propose folders and groupings. You review the temporary structure before importing it into Tree.
DEVELOP YOUR THINKING
AI Response can check reasoning, offer a counterargument, develop an idea further, or show another perspective. AI features run only after you request them.
LOCAL-FIRST DATA
Your library is stored on your device. Back Up Entire Library creates a portable file that can be restored after reinstalling the app or moving to another device. Automatic iCloud synchronization is not currently included.

PLANS

New accounts receive 15 monthly Shared AI Credits at no cost, which is sufficient to test both Smart Gravity and AI Response.
Sign in with Apple is optional for basic note-taking and is used for subscription reconciliation, Shared AI Credits, and account deletion.
