What it is
RegexPilot is a Mac-native visual regex builder with AI for assembling, inspecting, and testing regular expressions. Its categorized drag-and-drop blocks, inspector panel, and plain-English breakdown tree are linked to the pattern. Users can paste sample text to see matches and capture groups highlighted, and build replacements with draggable blocks. RegexPilot supports 21 regex flavors and sends patterns to the real engine used by each target language. The builder can export code for 21 languages and railroad diagrams as SVG or PNG. A library includes 50 curated patterns and supports folders, tags, and JSON import and export. Its VS Code extension synchronizes changes between the app and regex literals in the editor. Users can connect supported AI services with their own API keys or run AI offline with LM Studio, Ollama, llama.cpp, or LocalAI. The desktop app keeps patterns and settings on the device unless a share link is created. It requires macOS 14 or newer. The free plan is free and covers JavaScript and TypeScript engines; the one-time license costs €19, paid once and covers all 21 flavors.
