Remember numbers by their shape, not their digits

Brainbookmark helps you memorize essential numbers, from credit cards and bank accounts to IDs and phone numbers.

The Visual Memory Hook

Ever noticed it's easier to remember a PIN by the shape your finger makes on the numpad than by the digits themselves? Brainbookmark turns this intuition into a tool.

How it Works

  • Trace Patterns: Save your numbers and watch them play back as animated lines. These visual "shapes" stick in your brain better than raw data.
  • Smart Shapes: Use spaces (e.g., 123 789) to break long numbers into distinct, manageable visual segments.
  • Practice: Use the interactive numpad to test your muscle memory. If you get stuck, we'll show you the shape hint.

Private & Secure

We use the Web Crypto API to encrypt your data. Your numbers are locked with your password and stored only in your browser's local storage. No servers, no tracking.

Pro Tip: Use Spaces!

Breaking long numbers into smaller chunks makes them much easier to remember visually.
