The best tools to make diagrams online for free

Making outlines and concept maps are the best method to study and improve our mnemonic skills. Thanks to them we can summarize in a clear way that subject or class that we can’t remember and see how each of its topics interrelate with each other. It is not surprising that it is a key tool when reviewing and preparing for exams.

In a world as computerized as ours, it would be strange if there were no programs to make diagrams from our computer. Many of them can have a high price and not all of us can afford it. But… Did you know that there are also many tools to make diagrams online?

In today’s article we are going to offer you a selection of the best free web tools to make diagrams and diagrams online. From them you will be able to create a concept map quickly and easily and then download it to make it easier to study from it. Here we go!

Draw.io

Draw.io is an interesting open source tool from which you can create diagrams, charts, tables and all kinds of concept maps designed for studying.
