Markdown and Rich Text Format (RTF) are two types of text editors used with Contentful, a content management platform. Markdown is a lightweight markup language that allows users to add formatting elements to plain text while maintaining simplicity and readability. Its popularity stems from its power-user tool capabilities, resulting in better quality control over HTML tags, platform independence, and future-proofing. Rich Text Format (RTF) provides a wide range of formatting options, making it intuitive and familiar for most editors, allowing them to design how their writing looks on the page. With Contentful, users can choose between these two field types for text content, each offering unique benefits depending on their needs.
