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 running locally, ensuring complete privacy and eliminating the need for internet connectivity.

Key features include real-time transcription that displays words as you speak, support for speaking 4x faster than typing, and privacy-focused operation where audio never leaves your Mac. The app offers multiple AI models including Parakeet for fast English transcription and Whisper for 50+ languages, supports any audio source including microphone and system audio, and is optimized 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 real-time text display, and export results through copying, text export, or direct integration with other applications. The entire process occurs locally without cloud processing.

Benefits include faster content creation through voice dictation, accurate meeting transcription with speaker identification, and secure processing that keeps all data on-device. Use cases span AI prompting for tools like ChatGPT, meeting note-taking during Zoom or Teams calls, content creation for writers and journalists, and everyday writing tasks like email composition.

JustScribe targets professionals who value speed, accuracy, and privacy in transcription workflows, including content creators, business professionals conducting meetings, and anyone needing fast, private speech-to-text conversion on macOS devices.
