0. Frequently Asked Questions
How long does it take to save a memo?
Just pick a category and start typing — no complicated setup, done in 3 seconds. The goal is to catch your thought before it slips away.
What's the difference between Today and Someday?
Today holds what you need to handle right now, and Someday holds what you'll want to revisit later. They're automatically separated so nothing gets mixed up, and you can move items between them anytime.
How do I hand my saved notes over to AI?
Copy your selected notes as a whole and paste them directly into ChatGPT, Claude, or any AI you use. You can ask naturally, like "organize these notes" or "find the patterns."
As my notes pile up, how do I find what I need?
Search by keyword, then select the results all at once with checkboxes to delete them or move straight into AI copy.
Is my backed-up data sent anywhere outside the app?
No. You can back up your entire note history as text and load it all back in whenever you need — but all of your data stays on your device and is never transmitted externally.
Can I use it in English too?
Yes, Korean and English are both fully supported. Buttons, notifications, and guidance text all switch completely to match your chosen language.
Who is this especially good for?
We recommend it for anyone who wants to capture thoughts the moment they arise, keep tasks and ideas separate instead of mixed together, and organize and use their notes together with AI.

1. How storage works
- HYSS365 uses the storage space already on your device, so it's your own memory palace with no risk of external leaks.
- The storage needed for one photo can hold an entire book's worth of text.
2. Tips for entering notes
- Voice input is far more efficient than typing. It lets you capture your thoughts exactly as they are, without editing them down — which makes them more meaningful when you look back later.
3. Real usage data (beta test results)

4. Building a backup habit
- Create a HYSS365 file in your phone's notes app and upload it about once a month, so you can restore your memory anytime you need to.
- For faster AI uploads, convert your backup to PDF first — it speeds up how quickly AI can process your memory upload.
5. How to use the "Select All" button
Checks every checkbox at once.
How to use it: Search for what you need, select all results, then tap "AI Copy" → paste directly into your AI's input field.
6. How to use "Search & Select"
After you enter a search term, this button finalizes the resulting list of items.
How to use it: When you use AI Copy, the number of matching notes is shown, and tapping it copies them straight to your AI's input field in one tap.
Tip 1: After sorting notes into categories, add a short AI nickname at the start of each entry (e.g. "Chat," "Gem," "Claude"). Search by that nickname to find and check only the relevant notes, then upload them to continue the conversation thread with that particular AI.
Tip 2: Even notes you've forgotten about can be copied and uploaded to AI, then organized with a request like "find everything about XYZ and sort it by date." AI tends to remember context for about a week; after two weeks it may get confused — but you can always bring the memory back up again whenever you need.
7. When the search bar disappears (once Someday has a lot of notes)
As the number of entries in Someday grows, the search bar can get pushed all the way to the bottom of the screen. When that happens:
- Tap the "Edit" button on any note to jump to the input field.
- Type "1" into the search bar below the input field.
- Return to the input field, then delete the "1" — this jumps you quickly back to the search bar.
