Markdown on macOS

Read AI-generated Markdown without opening an IDE

A generated Markdown file is often ready to read, not ready to become a coding task. Slate Viewer gives local Markdown reports, notes, and documentation a calm reading view, with Raw and Light Edit available when you need them.

A reader for finished output

Keep generated Markdown in reading mode

Open a local `.md` file in Slate Viewer when your next step is to understand its content. A clear Preview gives you the document first; Raw is there when you need its original Markdown source.

Preview first

Read headings, text, lists, and the overall structure as a document rather than starting in an editor.

Raw when details matter

Switch to Raw to check the source text behind the preview without moving the file to a different app.

Light Edit for small changes

Make a focused local correction when the file needs one, then return to reading instead of building a workspace around it.

Finder support

Markdown Quick Look, plus a fuller reader when you open the file

Slate Viewer includes Markdown Quick Look support for a fast Finder preview. Open the Markdown file in Slate Viewer when you want Preview, Raw, or Light Edit in the app.

Quick Look is limited to Markdown. Slate Viewer does not claim Quick Look support for JSON, JSONL, CSV, TSV, TXT, or LOG files.

What Slate Viewer reads

A local reader for Markdown and adjacent result formats

Alongside Markdown, Slate Viewer supports JSON, JSONL/NDJSON, TXT/LOG, CSV, and TSV. It does not create AI content, sync a cloud workspace, or replace an IDE.
