FAQ

What are optimized subtitles?
Optimized subtitles are AI-enhanced subtitles that address issues with YouTube's default subtitles, such as errors, disordered timelines, and audio-video sync problems. They are classified by color: Red (auto-generated), Yellow (uploaded by creator), and Green (AI-optimized).
How are subtitles optimized?
The plugin automatically optimizes subtitles in the background based on your viewing history. Once complete, you'll receive an email notification, and the plugin will use the optimized subtitles (green button).
What's the difference between free and paid users?
Free users have a daily limit on videos, while paid users have no limit. Paid users access AI-optimized subtitles with background audio, speaker identification, and Gemini model translation. Free users use Google Translate and Edge TTS.
Why is AI translation not supported for red button subtitles?
AI translation is not supported for auto-generated (red button) subtitles because they are often of lower quality, potentially leading to wasted translation quota. AI translation is available for yellow or green button subtitles.
