Notion is an online workspace with a set of tools that can be used without any programming or technical knowledge. Users simply log in and add products that they have bought, or customize templates, or create pages for whatever they want such as creating a to-do list, organizing an event, writing a novel, collaborating with others on a project, building a public website.

There are over 30 million users worldwide, many of them on the free plan permanently. If only one person is going to use the application, then the free plan is quite fine. 

Two, three or more people in a team who need permanent access? Notion Plus pricing is extremely reasonable. Check it out here.
