Scratch

An offline-first markdown notes app with WYSIWYG editing, AI integration, and local file storage

Scratch is an offline-first markdown note-taking application designed for developers, writers, and knowledge workers who prioritize privacy and simplicity. The tool stores notes locally as plain .md files without requiring cloud accounts or subscriptions. Scratch features WYSIWYG editing that saves as standard markdown, AI integration with Claude and Ollama, keyboard-first navigation with command palette, and support for code syntax highlighting across 20 languages plus Mermaid diagrams and KaTeX math rendering.
