Capture
Capture first. Organize later.
Keep the momentum of thought. Every new Thought lands where you can find it again.
A workspace for ideas that have not found their shape yet
Turn thoughts into structure.
Capture freely. Organize later. See your ideas grow into a clear, navigable tree.

Built around the way ideas actually arrive
Thinking does not begin as a folder.
StructMemo lets ideas arrive before they are classified. Capture what appears, then return to connect, elevate, and organize it without losing the original flow.
- 01
Capture first
Give an idea a place before deciding what it means.
- 02
Connect what belongs together
Bring related Thoughts into the same branch when the relationship becomes clear.
- 03
Let structure emerge
Move from fragments to a navigable whole without forcing an early taxonomy.
How it works
A clear path from capture to structure.
StructMemo separates the moment of writing from the work of organizing, so neither interrupts the other.
- 01
Capture
Write immediately without deciding where the Thought belongs.
02Connect
Find related Thoughts, move them together, or elevate them into an Upper Structure.
03Structure
Navigate your Tree from the broadest concept to the smallest detail.
More than a notes list
A workspace where the whole stays connected to the details.
Capture, retrieval, hierarchy, and optional AI work together as one continuous thinking environment.
Thoughts
Keep every thought within reach.
Search recent work, reopen unfinished ideas, and continue from where you stopped.
Tree + Upper Structures
See ideas grow into structure.
Use folders, hierarchy, and Upper Structures to move between the whole and its details.
Smart Gravity
Let Gravity reveal the structure.
When you ask, Smart Gravity identifies relevant Thoughts and proposes a temporary structure. You review it before importing anything into your Tree.
AI Response
Develop the Thought, not just the note.
Check reasoning, explore a counterargument, extend an idea, or view it from another perspective.
- Check the reasoning
- Explore a counterargument
- Develop the idea further
- See another perspective
Local-first + backup
Your library begins on your device.
StructMemo stores the library locally and lets you create a portable full-library backup. Automatic iCloud synchronization is not currently included.
- Local library
- User-controlled backup
- No automatic cloud sync
Details that keep the work moving
Tools for writing, returning, and staying in control.
Each feature supports the same idea: capture without friction, then shape the material with intention.

Search inside the Thought you are reading without leaving the editor.
- 05
Read Aloud
Listen to an existing Thought with Apple’s installed system voices, without an AI request.

FAQ
The practical details.
Straight answers about storage, accounts, AI, backups, and subscriptions.
Is an account required?
No. Basic Capture, editing, organization, search, export, backup, restore, and Read Aloud work without a StructMemo account. Sign in with Apple is required for account-connected AI features, shared AI Credits, subscription reconciliation, Restore Purchases, and account deletion.
Where are Thoughts stored?
The StructMemo library begins as local data on your device. The complete note library is not automatically copied into a StructMemo cloud library.
Does StructMemo sync with iCloud?
No automatic iCloud synchronization is currently included. You can create a full-library backup and choose iCloud Drive, Files, or another document provider as the destination, but that file is a user-controlled backup rather than continuous sync.
What does Smart Gravity send?
Only after you explicitly request it, StructMemo may send the selected or retrieved Thought and Code text, titles, your instruction, and necessary structural context to the StructMemo backend and OpenAI. The result is a temporary proposal that you review before importing into the Tree.
Can I restore my library after reinstalling?
Yes, if you created an external full-library backup first. Deleting the app removes local content unless an external backup was created. Restore Library Backup validates the file and, after confirmation, replaces the current local library.
How are subscriptions managed?
StructMemo Pro and Pro Plus are purchased through Apple StoreKit. Apple handles billing, renewal, cancellation, and refund requests. Use Settings → Manage Subscription for subscription changes.
Does deleting my StructMemo account cancel my Apple subscription?
No. Deleting the StructMemo account does not automatically cancel the Apple subscription. It also does not automatically remove local Thoughts or external backup files. Manage the subscription separately through Apple.
What happens when Shared AI Credits run out?
An AI request that needs more shared credits will not run until credits later become available under the applicable monthly plan policy or the plan changes. Local Capture, Thoughts, Tree, editing, search, export, backup, and Read Aloud continue to work.
Is StructMemo available in Korean?
Yes. StructMemo includes English and Korean interface localization, and this product site is available in both languages.
What is an Upper Structure?
An Upper Structure is a named higher-level context for related branches of the Tree. It helps you move between a broad concept and the folders and Thoughts that develop it.
Start with what appears
Give your thoughts somewhere to grow.
Capture what appears. Return when you are ready. Build the structure over time.
