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.
Wikilinks
Link between notes with [[double brackets]]. Click to navigate, or let the AI create new linked notes for you.
Full-Text Search
FTS5-powered indexing with semantic embeddings. Find anything in your vault instantly by meaning, not just keywords.
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.
Markdown that feels alive
Live syntax highlighting, wikilinks, and native macOS performance. No Electron, no web views — just a fast, beautiful writing surface.
Live Syntax Highlighting
Headers, bold, italic, code, links, wikilinks, blockquotes, and checklists — all highlighted as you type.
4 Hand-Crafted Themes
Switch between Midnight, Cream & Ink, Aurora, and Paper. Each theme extends to the editor, sidebar, and AI panel.
Export Anywhere
Export your notes as PDF, HTML, or DOCX — one click from the toolbar or command palette.
macOS Native
Built with SwiftUI and AppKit. No Electron, no web wrappers. Instant startup, low memory, and it just feels right.
Start writing in seconds
No account, no cloud sync, no setup wizard. Just open a folder and write.
Open a vault
Point Sandtype at any folder of markdown files. Your notes stay as plain .md files — no import, no conversion, no lock-in.
Write in markdown
Use the live-highlighted editor with wikilinks, command palette, and full keyboard-driven navigation.
Let AI assist
Ask the AI to draft, edit, research, or organize. It reads your notes, writes to them, and remembers your preferences.
