Tangent lets you write the way you think. Your thoughts are connected; Tangent lets you link to existing notes and make new ones with ease. Let your mind wander along the path of interest. Don't suppress tangential thoughts; embrace them. Key features include:
Tangent reads and writes plaintext notes using a loose interpretation of Markdown syntax. Text is rendered in a pseudo-WYSIWYG style, with formatting characters appearing only when you need them. Tangent supports bold, italics, headers, lists, links, images, todos, tags, inline code, block code with syntax highlighting, inline and block KaTeX math, color highlights, strikethrough, and comments.
