Quick Subtitles

Quick Subtitles is a powerful, but simple app that transforms audio and video files into accurate text transcriptions and subtitle files, 100% on your own device.

Just drag, drop, and done. Drop any audio or video file into the app and get a full transcription in seconds. Export as plain text or SRT subtitle files, ready for your favorite video editor.

Two Speech Engines

- Apple Speech Analyzer - Fast and accurate, built right into your device

AI-Powered Cleanup

Transcriptions aren't always perfect. Use AI to find and fix errors with an inline review that shows you exactly what changed before you accept. Or turn on YOLO mode and let it fix everything automatically.

Choose your AI: use the built-in Quick Subtitles AI subscription, or bring your own API key for Google Gemini or OpenAI.

Go beyond transcription. Use AI to generate summaries, show notes, key takeaways, action items, or anything else with fully customizable prompts.
