What is Slate Viewer?

Slate Viewer is a native Mac app for reading local AI result files. It opens Markdown, JSON, JSONL/NDJSON, TXT/LOG, CSV, and TSV on macOS 26.0 or later, starts with a readable Preview, and keeps Raw source available when details matter. It does not generate AI answers or create a cloud workspace around your files.
