# What is a block?

> See there.do as a set of building blocks: create notes and documents the way you need

## Everything in there.do is a block

A document is built block by block: heading, paragraph, image, task, table, and more.

Each element stays independent, so you can structure a document freely without a rigid format.

A note is also a block: you can drag and drop it into a document like any other element.

## Blocks can transform

Any block can be converted into another block type to present the same information differently.

Common examples:

* convert a paragraph into a heading
* convert a list into a checklist
* convert text into a task

To convert a block, open the block options menu and choose the conversion action.

You can also ask AI in natural language to make these changes directly from the block options.

## Blocks can be rearranged

Use the block handle <Icon icon="grip-vertical" size={16} /> to drag and drop an element anywhere on the page.

You can quickly reorganize a note or report without cutting and pasting text.

The same handle also gives access to block options and related AI actions.
