JustScribe is a local-first live transcription application designed specifically for macOS that enables instant speech-to-text conversion entirely on-device. The app provides real-time transcription capabilities powered by AI models without requiring an internet connection, ensuring complete privacy and data security.

Key features include real-time transcription that displays words as you speak, the ability to transcribe 4x faster than typing for drafting emails and documents, and privacy-first architecture where audio never leaves your Mac. The app supports multiple AI models including Parakeet for fast English transcription and Whisper for 50+ languages, works with any audio source including microphone and system audio, and is optimized natively for Apple Silicon with minimal battery impact.

The application works by allowing users to select their audio source (microphone, system audio, or specific apps), start transcribing with a single click to see words appear in real-time, and then export the transcription by copying to clipboard, exporting to text files, or sending directly to other applications. This simple three-step process ensures immediate usability without complex setup requirements.

Benefits include faster workflow efficiency for AI prompting by speaking prompts instead of typing, comprehensive meeting transcription for Zoom and Teams calls with speaker identification, content creation assistance for writers and journalists through voice-to-draft functionality, and everyday writing applications for email composition and message replies. The app enables users to work at the speed of thought while maintaining complete control over their data.

JustScribe is built for professionals who value speed, accuracy, and privacy in their transcription workflows, particularly those working with AI tools, attending meetings, creating content, or handling everyday writing tasks. The application integrates with macOS natively and leverages on-device machine learning technologies without requiring any cloud services, accounts, or data collection.
