Text to Speech for Markdown Files

Markdown is the default writing format for a lot of people who live in plain text: developers writing READMEs and docs, bloggers drafting posts for static sites, researchers keeping notes in Obsidian, and writers who prefer the simplicity of a format that works in any text editor. These files accumulate. Listening to them turns a screen-only workflow into something you can do while walking, commuting, or resting your eyes.

The most common use case is proofreading. When you write in Markdown, you see the rendered output in a preview pane, and your brain fills in the gaps. Hearing the text read aloud by a different voice catches errors that survive both the source view and the preview. For more on this, see how to proofread by listening.

Another use case is reviewing your own notes. If you keep a Markdown knowledge base or journal, listening back to entries helps you spot patterns and ideas you forgot you had. The voice is neutral and consistent, so you hear the content, not your own handwriting or formatting choices.

The tool does not matter much. The PDF just needs to contain readable text in a single-column layout. Here are the options that produce clean output:

• Pandoc (free, cross-platform). Run pandoc file.md -o file.pdf in a terminal. Pandoc renders headings, lists, bold, italics, and code blocks correctly. The PDF is plain but perfectly readable.
• Marked 2 (Mac, paid). Marked is a dedicated Markdown previewer that exports clean PDFs with good typography. Open your .md file, pick a style, and export. The PDF looks like a printed document.
• iA Writer (Mac, iPhone, paid). iA Writer exports Markdown to PDF directly from the app. The output uses iA Writer's distinctive typography and reads well.
• Obsidian (free, cross-platform). Install a PDF export community plugin, or use the "Print to PDF" option in the system print dialog. Output varies by theme, but the text is always there.

Once you have the PDF, open it in LoudReader, import the file, and press play. The app reads the rendered text. Headings get natural pauses. Lists get read as sequential items. Bold and italic text look different in the PDF but sound the same.

A few things, and it helps to know them upfront:

• Links. The PDF shows linked text, but a TTS voice reads the link text without indicating it is a link. "Click here" sounds like two words, not an invitation. Write descriptive link text (the thing the link points to) if listening matters.
• Images. Images in the Markdown render into the PDF but produce no audio. Alt text and captions get read, which helps. If an image is essential to understanding the document, describe it in the surrounding text.
• Code blocks. Code blocks render as monospaced text in the PDF. The TTS voice reads each line as prose. A short example is fine. A 50-line function sounds like someone reading code aloud, which is only useful if you are reviewing it for correctness.
• Tables. Markdown tables render as visual tables in the PDF. The TTS voice reads them in document order (cell by cell, left to right, top to bottom), which rarely matches how a human would scan a table. For table-heavy docs, listen to the prose and review tables on screen.

Yes, and the pipeline works well for it. Write your draft in Markdown, render it to PDF, import into LoudReader, and listen while you have the original .md file open in a separate window. When you hear a problem, pause playback and fix the source file. When you want to re-check a section, re-render and re-import.

This catches a specific class of errors that visual proofreading misses. Consider this sentence from a real draft: "The function accepts a parameter and returns the result to the caller after processing the input." Reading it silently, your eyes skip through. Hearing it read aloud, you notice it is 18 words that say almost nothing. This is the kind of discovery that listening produces. Catching typos in your own writing covers more techniques for this.

The whole pipeline runs on your device. LoudReader is fully on-device and private, your library never leaves your device. No draft is uploaded to a server, no text is processed in the cloud. For writers working on unpublished material, this matters.
