Write notes, draw, and share everyday photos and ideas with people on StructMemo. Only what you choose to publish becomes public in Signals. CAPTURE WITHOUT LOSING THE THOUGHT Write a Thought when it appears. Keep related notes together, organize them into folders and larger structures, and use Tree to travel from a broad idea to its details. WRITE AND DRAW IN ONE STRUCTURE Use Mind for writing and Vision for artwork inside the same evolving structure. Move between Thoughts and Visions while keeping their shared context. DRAW IN THE INTEGRATED STUDIO Work on a full-screen canvas with drawing tools, color, fills, and layers. Develop a quick visual note or a finished Vision while keeping it connected to the thinking around it. PRIVATE UNTIL YOU CHOOSE TO RELEASE Entering Signals uploads nothing. Your private structures remain private. A Thought or Vision becomes public only after you deliberately release it. You choose the public name, message, category, appearance, and whether to display a country you have confirmed. DISCOVER WHAT OTHER PEOPLE RELEASE Stream starts with the people you tune in to and mixes in recent public Signals from the region you choose, in a random order with unseen ones first. Rising shows Signals where more different people joined the conversation in the last hour than the hour before, recomputed hourly for everyone alike. The Library gathers public Signals into books on human subjects, placed there by their authors. Visit an Origin to see a person's public message, Thoughts, and selected Visions, and tune in if you want to follow them. READ WITH THE PEOPLE YOU CHOOSE Tune In is a one-way sign of interest and completes on its own. When two people tune in to each other, each can read what the other published to mutual readers only. Your Shelf holds your own books of what you published; nothing you read, save, or search is used to guess your taste — Stream uses only the people you tune in to and the region you choose. SHARE THE FINISHED WORK OR HOW IT DEVELOPED Release a Vision as Final Only, Layers Included, or Process View. Share only the final image, let people inspect the layers you include, or present selected stages from the work's development. LOCAL-FIRST LIBRARY Your private library is stored on your device. Back Up Entire Library creates a portable file you control. Automatic iCloud synchronization is not currently included. Public Signals are separate and exist only for content you deliberately release. AI ONLY WHEN YOU ASK Smart Gravity, AI Response, and other AI-assisted actions run only after the applicable user action. Review suggestions before bringing them into your structure. PLANS Core Capture, Thoughts, Tree, and Elevate features are available free. Optional StructMemo Pro and Pro Plus monthly subscriptions provide larger Shared AI Credit grants and expanded limits. Available products and localized prices are shown in the app. Apple handles billing, renewal, cancellation, and refunds.
