The Problem with Traditional Note Apps

Security and organization shouldn't be compromised

Vulnerable Data Storage

Most note apps store your data in plain text or with minimal protection, leaving your sensitive information at risk.

Limited Search Capabilities

Traditional search only finds exact matches, missing the context and connections between your ideas.

Proprietary Data Formats

Many apps lock your notes in proprietary formats, making it difficult to own and control your information.

Solution

Simple. Powerful. Peace of Mind.

The files and folders apps may have created pointless time consuming habits, but it's time to experience fun, usefulness thanks to AI.

AI Auto Organization

Focus on thinking and working, let AI do the boring stuff.

Connected Thinking
