2. Visual Organization vs. Task Management: Milanote thrives on visual organization, offering users the freedom to create boards filled with images, notes, and links to inspire creativity and facilitate collaboration.

5. Mobile Experience: Asana offers a robust mobile app that allows users to manage tasks, track progress, and communicate with team members on the go. Milanote, while accessible on mobile devices through a web browser, does not have a dedicated mobile app, which may limit its usability for users who prefer mobile-centric productivity tools.

6. Price and Plans: Asana offers a free basic plan with limited features, as well as premium plans with advanced features for individuals and teams.
