RegexPilot is a Mac-native visual regex builder with AI for creating, inspecting, and testing regular expressions. Users assemble patterns from categorized drag-and-drop blocks, examine them in an inspector, and use a plain-English breakdown tree linked both ways to the pattern. Sample text displays highlighted matches and capture groups, while draggable blocks can compose replacements. The app supports 21 regex flavors and sends patterns to the real engine used by each target language. Users can provide API keys for listed AI providers or run AI offline with LM Studio, Ollama, llama.cpp, or LocalAI. Its library includes 50 curated patterns and supports folders, tags, and JSON import/export. A VS Code extension synchronizes regex literal edits between the editor and app. Users can export code for 21 languages, produce railroad diagrams as SVG or PNG, and create browser-openable share links. The desktop app requires macOS 14 or newer. The free plan is 0.00 EUR per free and covers JavaScript and TypeScript engines. The RegexPilot license costs 19.00 EUR per once and includes all 21 flavors and free updates throughout v1.x.
Who it is for
It suits Mac users who build or inspect regular expressions across multiple language flavors. The free plan is limited to JavaScript and TypeScript engines; broader flavor support requires the one-time license.
