aida — WYSIWIG Markdown Editor for macOS: Markdown for humans

aida writer is a Markdown editor that doesn't ask you to choose between writing naturally in plain text and seeing your document formatted. Type bold and it's bold. Type a heading and it looks like a heading. Whether you are creating quick notes, or writing larger documents - you can remain focused on your content, not how to markup the document so that it formats correctly. Under the hood, your document is always a standard .md file — nothing proprietary, nothing that only opens in this one app. WRITE NATURALLY • Bold, italic, underline, strikethrough, inline code, and highlighted text — from the toolbar, the Format menu, or standard keyboard shortcuts • Six heading levels, blockquotes, horizontal rules, and fenced code blocks with syntax-highlighting language tags • Type a web address or email and it becomes a clickable link automatically — no extra step • Type 😄 or any of 250+ emoji shortcodes and watch it resolve as you type BUILD REAL STRUCTURE • Bulleted, numbered, and checklist lists — start one just by typing "- " or "1. " • Tab and Shift-Tab indent a whole selection of list items at once, any mix of types • Full table support: insert, resize, reorder rows and columns, set column alignment, or paste a table straight from Excel, Numbers, Word, or Pages • Insert links and images, or just paste an image straight from the clipboard STAY ORIENTED IN LONG DOCUMENTS • An Inspector with a clickable heading outline, word count, and reading time • Find & Replace with match case, whole word, and regular expression support — built on macOS's own find bar • A live Side by Side view of the raw Markdown source, which can pop out into its own window A MAC-NATIVE DOCUMENT, NOT A WEB APP WEARING A COSTUME • Autosave and Versions, exactly like every other Mac document • Light, Dark, or System appearance; set a default save folder; toggle spelling and grammar checking independently • Export a self-contained HTML file, or copy your whole document as Markdown to paste into GitHub, Notion, or Slack • Available in English, French, German, Spanish, Japanese, Simplified Chinese, Brazilian Portuguese, Italian, Korean, and Russian Your files are just files.
