TinyStudio: Free Mac Subtitle Generator with Whisper AI
TinyStudio is a free Mac app that generates accurate subtitles in one click using M1/M2 chip acceleration and OpenAI's Whisper, all processed locally.
Overview
TinyStudio is a free macOS application built specifically to harness the speed of Apple's M1/M2 chips for lightning-fast subtitle generation. By tapping into OpenAI's Whisper technology, it transcribes video and audio files directly on your device, meaning no internet connection is required and your content stays private. The one-click workflow removes the technical barriers typically associated with subtitle creation, making it accessible to anyone regardless of editing experience.
Beyond raw transcription speed, TinyStudio includes a rule-based correction system designed to catch common errors and improve overall accuracy, along with flexible subtitle import and export options that fit into existing editing pipelines. The clean, user-friendly interface—complete with a dark mode—keeps the experience simple whether you're captioning a quick social clip or a longer marketing video. It's a practical, no-cost solution for vloggers, marketers, and social media creators who need reliable subtitles without paying for cloud-based transcription services.
