Subtitle Translator for Udemy geliştiren: Jung K

Automatically translates Udemy and Udemy Business subtitles in real time, using your own free API key from Groq, Cerebras, Gemini, or OpenRouter. If the active provider hits a rate limit, the extension automatically switches to the next one so subtitles keep flowing.

Features:
- Reads subtitles directly from the Udemy player (native captions, with a DOM fallback for lectures without a standard track)
- Automatic failover across up to 4 free translation providers, with in-memory caching to avoid duplicate requests
- Draggable, resizable subtitle overlay — customize font size, text color, background color, opacity, and width
- Works in fullscreen, and follows lecture changes automatically since Udemy is a single-page app
- Supports *.udemy.com, including Udemy Business org workspaces

Setup: open the extension's Settings page, paste in at least one free API key (get one from Groq, Cerebras, Gemini AI Studio, or OpenRouter - no payment required), then pick your target language.

Your API key and the current subtitle line are sent directly to the provider you configure - never to any server run by the developer. Full source code and privacy details: https://github.com/jungdevtoday/subtitle-translator-for-udemy
