How do I preview technical Markdown on iPhone or iPad?
Install Md Preview, open the file from Files or the iOS Share Sheet, and preview it locally on iPhone or iPad. When ChatGPT, Claude, Gemini, Obsidian, Notion, GitHub, Mail, iCloud Drive, Google Drive, or Dropbox gives you a Markdown file, open it in Md Preview for a clean rendered view. No subscriptions. No in-app purchases. No ads.
The iOS gap this app solves
AI chatbots, GitHub projects, note apps, and documentation tools produce Markdown files every day. On iPhone and iPad those files are often hard to read without a dedicated viewer.

How it works
Receive a file
Save or receive a .md, .markdown, .mdx, .rmd, or .qmd file.
Open with Md Preview
Use the iOS Share Sheet, Files app, or file handler.
Read instantly
Markdown renders locally with a calm, readable layout.
Why this Markdown workflow breaks on iOS
Technical Markdown often includes code blocks, formulas, Mermaid diagrams, tables, and long documentation. Plain text makes those files harder to inspect on iPad.
The shortest answer
Install Md Preview, open the file from Files, the Share Sheet, or the source app, and preview it locally. The app has no subscriptions, no in-app purchases, and no ads.
The code, math, and Mermaid diagrams workflow
Open the file in Md Preview to render the technical structure in a readable iOS layout.
What to check before opening
This is especially useful for AI-generated specs, engineering notes, course material, and documentation drafts.
Why local preview fits this job
Md Preview is focused on file preview. It avoids uploads, account setup, ad clutter, and heavy editing features when the user simply needs to read a Markdown file now.
If you also receive HTML files
AI and document workflows often produce both Markdown and HTML. Html Preview is the companion viewer for that file type.
