Why Markdown?

Markdown, without memorising the syntax

Markdown is a plain-text format for headings, lists, links, and more. You may have encountered it while working with AI assistants or other apps.

AgentEd lets you edit these files visually. Format headings, lists, images, and tables with visual controls, then save ordinary Markdown in your own folders. No account required.
