Wander is a WYSIWYG Markdown editor for Mac, iPhone and iPad. You write in formatted text, and your notes stay plain .md files in folders you choose. Open an Obsidian vault as it is. Math, Mermaid diagrams, tables and photos render as you type. Your notes sync for free through iCloud Drive or Dropbox, with no account. Wander Cloud is optional: private vaults, sharing, and your notes in ChatGPT and Claude.
