Everything you need to write

Sandtype is built for writers who want the power of AI and the simplicity of markdown — without the bloat.

AI Writing Assistant

An AI that doesn't just chat — it reads your notes, writes to them, and searches your vault. Give it instructions and it takes action.

Command Palette

Hit ⌘K to fuzzy-search notes, folders, and actions. Navigate your vault at the speed of thought.

Vault Organization

Your notes live as plain markdown files in folders you control. No proprietary formats, no lock-in. Drag and drop to organize.

Beautiful Themes

Four hand-crafted themes — Midnight, Cream & Ink, Aurora, and Paper. Each designed for long writing sessions.

An AI that actually does the work

Most AI tools just chat at you. Sandtype's AI reads your notes, writes to them, searches your vault, browses the web, and remembers your preferences — all within your editor.

  • Reads & Writes Your Notes

    The AI has full access to your vault. Ask it to draft, edit, rewrite, or expand — it writes directly to the file.

  • Searches Your Vault

    Ask a question and it searches across all your notes to find relevant context before answering.

  • Web Research

    Built-in web search and URL reading. Ask it to research a topic and write findings directly into your notes.

  • Memory & Skills

    The AI remembers your preferences over time and can load custom instruction sets (skills) for different writing tasks.

  • @Mention Notes

    Tag specific notes or folders in your prompt with @ — the AI reads them as context for better, more targeted responses.

  • Conversation History

    Every conversation is saved per-note. Switch between past threads or start fresh anytime.
