 Everything in Notion is made up of blocks. Including text, images, tables, and pages themselves. This allows users to easily customize a page by adding and moving blocks in various ways. In June 2021, Notion released a 'synced block', which is a type of block that, when copied and pasted across different pages in a user's workspace, shows edits between them.
 One of Notion's features is its database. Databases are used for storing information and can hold any number of rows and columns. By default, each row will have two pre-populated properties: 'Name' and 'Tags'. Users can add more properties, such as date, checkbox, multi-select, URL, and more. When creating databases, users can choose to either create it 'inline', within an already existing page, or as its own page.
 Notion users can make and use templates. Notion hosts its own template gallery, where users can browse through templates made by other Notion creators. However, not all of these templates are free to use. Some creators profit from selling Notion templates. Jason Ruiyi Chen, from Singapore, made $239,000 by selling his Notion templates to his Twitter audience. Thomas Frank, a YouTuber with 2.8 million subscribers as of February 2023, made $1 million in 2022.
 Notion AI uses artificial intelligence, which enables prediction of some results, text generation and solving arithmetic. It will also work with other datasets in response to an input by the user of the AI. This AI can automate some tasks, and assist the user to make a paragraph or outline from a single line of text. Notion AI has its own subscription set which is $10/month/person.
 Notion has a four-tiered subscription model: Free, Plus, Business and Enterprise. Users can also earn credit via referrals. As of May 2020, the company changed the Personal plan to allow unlimited blocks.
