THOUGHTFUL HELP FOR ANY TASK Lumo handles everything from quick questions to more complex work. Choose Fast for quick answers or Thinking for multi-step reasoning.

Memory retains context and preferences across sessions, and you can set tones and styles to get the exact Lumo experience you want.

MD Editor opens Markdown, HTML and text files from your device and saves them back in place — not into a copy you have to export later. WHY IT EXISTS On iOS, Files cannot open a .md file for editing, and there is no way to look at the HTML source of a page you saved. MD Editor fixes exactly that. EDITING - Inline preview: the line your cursor is on stays raw source, every other line is formatted - Syntax highlighting for Markdown, HTML and plain text - A keyboard row with the symbols these formats actually need - Autosave, with conflict detection if the file changed on disk - Files opened from your device are always free to edit and save, with no limit VAULT Documents you create inside the app live in a private vault. The free vault holds three documents. MD EDITOR PRO - Unlimited vault documents - Export to Markdown, HTML, text and PDF - Live HTML preview and render - Connect more than one folder - Syntax highlighting for Python, Swift, JavaScript and more - Mermaid diagram and LaTeX math preview (also in PDF) PRIVACY No account. No server. No analytics. Your files stay on your device. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://mdeditor-app.pages.dev/privacy
