A personal operating system
Capture first.
Organize later.
The quiet place for everything on your mind. Write freely. CoreOS keeps the original safe, then lets AI put it where it belongs.

Tomorrow call the workshop to ask for an appointment
The principle
Most tools ask you to organize before they let you save.
That tiny decision is enough to make a thought disappear. CoreOS removes it. There is one place to put something down, and time to decide what it means later.
Write the thing down. Keep the thing safe. Let the system do the sorting.
The quiet machinery
A simple order of operations.
CoreOS is deliberately boring in the best way: capture is immediate, organization is asynchronous, and your words are never rewritten to make the system look smarter.
- 01free-form text
Capture
Type whatever is in your head. No folders, forms, or decisions required.
- 02on-device first
Persist locally
The raw capture lands in SQLite on your device before any AI call is made.
- 03retryable
Classify with AI
When the system is ready, a model suggests the domain and useful metadata.
- 04five domains
Organize automatically
Your original words arrive in Notes, Tasks, Expenses, Habits, or Sleep.
Inside CoreOS
A calmer interface for a noisier life.
Three places you return to: what needs attention, what you want to capture, and what you have kept.
One inbox, many lives
A place for the whole picture.
Notes are only the beginning. A single capture can become whatever kind of record it needs to be, without making you choose up front.
The local-first promise
Your second brain should not need a second account.
CoreOS is built for one person, on one device. The database lives locally. Your key lives in secure storage. If the model fails, your original capture is still there waiting.
- SQLite on deviceYour data lives where you use it.
- No backend. No account.No remote service sitting between you and your notes.
- Capture never gets lostAI can fail. The original text does not.
