Gellish is like a special way of organizing information in a computer. You know how you have a toy box and you put all the toy cars in one place and all the action figures in another place? Well, Gellish does the same thing, but with words and ideas instead of toys.
Imagine you have a list of words like "cat", "dog", and "bird". Gellish helps you organize these words based on what they have in common. So, you might put "cat" and "dog" in one group because they are both pets, and "bird" in a different group because it flies.
This way, you can quickly find the things you are interested in, because all the related words are grouped together. Gellish helps people share and understand information better, especially when they are working on complex projects together.
