Milanote's Free plan lets you try all the features offered on the Pro plan. It's the perfect way to trial Milanote and you can use it for as long as you like.
The Free plan lets you add up to 100 cards (notes, images, links, etc.). If you want to add more content than that, you can upgrade to the Pro plan. The Pro plan has the same features but lets you add unlimited content and larger files.
