Features

You need the right tool, not the most

Note-taking finally returned to its roots: speed, privacy and full control. No extra subscription, no ad tracking, no unnecessary notifications.

Write Freely

The editor follows you, not the other way around. Real-time Markdown: from headings to code snippets, from quotes to tables, without lifting your fingers from the keyboard.

Store Securely

Even the developers who wrote the code can't access your notes. Row-Level Security isolates every note at the database level: no server access, no admin panel.

Share Smartly

Create a secure sharing link with one tap; make it public or share with just one person. Invalidate the link whenever you want.

Offline-First

Lost connection? You won't lose your notes. The app manages all content locally; works at full speed even on travel, on planes, when power is out.

Markdown Support

Plain text is no longer enough. **Bold**, *italic*, `code`, > quotes, tables, task lists: type the symbol, the result appears instantly.

Fast Search

Forgot the title, only remember two words? Full-text search lists the relevant note in seconds; no idea stays in the dark.

How It Works

Three steps, one minute, get started

From creating an account to sharing the first note, the whole process is less than a minute.

01

Download the App

Download for free from the App Store or Google Play. Create an account with email in 30 seconds, no payment info or subscription needed.

02

Write Your First Note

Tap the + button, start writing. Title, Markdown content, visibility: private, token-holders only, or public.

03

Share with Who You Choose

Tap Share; the app generates a unique token. That link belongs only to that person. Revoke it with one tap whenever you want.

Privacy is Not a Feature, It's Our Core Principle

Privacy in NotIdea wasn't added later; it's the core of the architecture. Every note is isolated at the database level with Row-Level Security: no app employee, no server, no advertiser — no one other than the owner can see it.
