I came across Whimsical around an year back while I was learning to create UML diagrams and sequence diagrams, and I must say I was amazed with what I discovered. Whimsical is loaded with various features which I used to keep at different places randomly prior to this. Like for mind mapping, I used xmind but for flowcharts I used draw.io, lucidchart and even figma, but since I discovered whimsical, I loved how it provides these and various other features right out of the box. I am always on a lookout for centralizing so much of my thoughts, notes, diagrams and whimsical solves for it by giving all these features at one place. Its very easy to use and helps me keep my ideas and notes very visual. What i also love is the way it works in tandem with other tools - like notion where I can integrate it easily, and with chatgpt which has a plugin of whimsical and gives code to directly paste the sequence diagram from chatgpt to whimsical.

Aparte de ser la mejor opción gratuita en su categoría, tiene muchos plantillas para comenzar.

Mind map are very quick and smooth. The feature to encrypt and decrypt multiple layers are of its kind. Never seen in any other product. Very good. It's like a blank canvas you can use multiple elements like text, mind maps, and charts to brainstorm and structure your thoughts. Being a PM it's was very helpful for me during the brainstorming of large product ideas.
