🚀 QuickSub Pro

<aside> ✨

Welcome to the official documentation for QuickSub Pro, the ultimate AI-powered captioning plugin for Adobe After Effects and Premiere Pro.

QuickSub Pro uses an on-device AI model (Whisper) to automatically transcribe your audio and generate dynamic, animated captions directly on your timeline. It operates entirely locally on your machine for maximum privacy (with internet required for Hinglish transcription and the Gemini AI Grammar Corrector).
