Our app puts three core values to the fore: simplicity, visualization, and consensus.

By creating an infinite canvas where cards, much like sticking notes, resemble a neatly organized collection of inter-related ideas. They serve as units of thoughts with clear borders, displayed on a squeaky-clean white canvas.

To preclude the document from becoming messy as the number of cards augments, we betted on functions that are clear-cut and intuitive. They include drag’n’drops; deep dive; tabs within a document; embedded pictures, videos, and links; sub-pages. As a result, the users get a well-organized, easy-to-navigate space.

Rather than providing bits and pieces of scattered information, the tool gives you a bird’s-eye view of the cards, creating the big picture.

Pillared by simplicity and visualization, the app offers a collaborative space for teams to work together in real-time, sharing cards and elaborating on ideas.

FlexNote is a local-first visual note-taking and knowledge management app designed for deep learning, research, and creative thinking.

Unlike traditional note apps that organize information in linear documents and folders, FlexNote lets you place cards freely on an infinite canvas, connect ideas visually, and transform your notes into dynamic mind maps.
