About
Slate Viewer opens the files AI tools produce as readable pages instead of raw text. Markdown, JSON, JSONL/NDJSON, TXT/LOG, CSV and TSV each get a clean preview, with a Raw mode for checking the source and a light edit mode for small fixes. Markdown can be translated between English and Simplified Chinese without touching the original file, and the app adds Finder Open With and a Quick Look preview for Markdown. Files stay on your Mac. Requires macOS 26 or later.
