Slate — Think in markdown. Reason with AI.
Slate is a macOS knowledge base that connects your notes to your thinking — and your thinking to AI. Local, fast, and built around the format LLMs actually understand.
Features
- Unlimited markdown notes stored as plain .md files
- Local file storage — your notes never leave your machine
- Folder-based organization
- Split editor with live preview
- Autosave without dialogs
- Smart file naming from first heading
- Light and dark mode
- Universal binary for Apple Silicon and Intel
How it works
- Write without friction. Plain markdown, nothing in your way. No blocks, no databases, no formatting toolbar.
- Find what you forgot you knew. AI reads your entire vault and surfaces connections between notes.
- Ask your notes a question. Get answers grounded in your own writing. Not the internet — your thinking.
