Notes that nobody else can read.
Not even us.
Encrypted on your device before they ever leave it. Even we can't read them.
Free forever · No credit card · No cloud AI · No tracking
Zero-knowledge by design
Even we can't read your notes.
Drag the slider. The left is what you write; the right is the scrambled ciphertext our servers actually store. Your key is only ever unsealed on your device — so only you ever see the left.

Felt steadier this week. The breathing
exercise actually helped before the meeting
— want to keep that up next week too.
How your notes travel
Encrypted before it leaves. Decrypted only by you.
A note is locked on your device and stays locked everywhere else — the key travels only sealed with your PIN.
You write a note
Encrypted on-device with your key.

What's inside
The features you'd expect, and nothing else.
Almost everything is free. The few power features marked Pro need a subscription — see the full comparison.
End-to-end encryption
The server never sees your text — only ciphertext. Encrypted on your device before it leaves it. Your PIN, your key, your notes.
Flexible 2FA
TOTP authenticator, email code, or PIN-only. You choose your unlock flow.
Folders & tags
Deeply nestable folders, tags, and drag-and-drop organization.
Rich text editor
Plain text is free. Pro adds headings, bold, lists, tables, images, and code blocks.
Reminders
Set a date & time on a note and get a push notification, with an email fallback.

Multi-platform
Web app on any browser. Windows and Linux desktop apps. Android coming soon.
What Dim Notes is
Three things, done deliberately.
A private notebook.
Encrypted on your device before it leaves it. The server stores ciphertext. Even we can't read your notes.
No cloud AI.
Your notes are never sent to a cloud AI service or used to train anything. If AI features are ever added, they run entirely on your device — the content never leaves it.
Not a workspace.
No databases, no blocks, no templates. Open the app, write something down, find it later.
