About Script Looper - YouTube Loop & Context AI
How to Use Script Looper

AI context translation and bilingual subtitle panel
Click the Translate button at the top of the subtitle panel. A ChatGPT window opens on the left, and translations are added line by line to the subtitle panel as they are generated. When translation and bilingual overlay are complete, the ChatGPT window closes.
Long videos are processed in 5-minute segments. When a segment is fully translated, its number button turns blue. Click a blue button again to hide that segment’s translations.
