About Udemy Custom Script

Udemy Custom Script is built for learners who want more control over how course subtitles are translated and displayed. Most transcript tools stop at extraction. This extension goes further: it lets you export the current Udemy lecture transcript with structured metadata, translate it with your own workflow, then import the completed script back into the extension and watch the lecture with custom subtitles rendered directly inside the Udemy player. Why install it: - You are not locked to one translation service. Instead of being forced into a fixed tool such as machine auto-translation, you can use GPT, Gemini, or any workflow you prefer. - You can create translations that match your goals. If you want more literal wording, more natural lecture-style phrasing, or terminology customized for programming, design, game development, or exam study, you control that process. - Your translated script is matched back to the exact course, section, lecture, and transcript language, so the extension can recognize the right lecture quickly and display the correct subtitles during playback. - You can watch with translation only or with both source text and translation at the same time. - You can customize how subtitles look in the player, including font style, font size, line spacing, background opacity, padding, and display order for source and translated lines independently. - You can prepare better LLM translation prompts using built-in guidance that explains the metadata format and helps preserve lecture intent and terminology. This makes the extension useful for users who: - want higher-quality translated subtitles than one-click automatic translation - study technical courses where terminology consistency matters - prefer to review both the original lecture language and the translated line together - want a reusable workflow for building their own learning subtitles Udemy Custom Script is designed around user-controlled translation quality and real playback usability, not just transcript export.
