Translate any word in video subtitles with one hover
Hover any subtitle word to get instant translation, examples and pronunciation on YouTube, Netflix, TED and 10+ video platforms. Free Chrome Edge FireFox extension.
Hi Product Hunt! 👋
I built Sublern because I was tired of constantly pausing Netflix and YouTube to look up words in a dictionary. Every time I tried to learn English through movies, I'd lose the flow, the context, and honestly — the joy of watching.
So I created Sublern: an AI-powered Chrome extension that translates any word in video subtitles instantly. Just hover → translation appears right on the video. No tabs. No pauses. No context lost.
✨ Features:
• Instant AI translation on hover
• Native pronunciation with one click
• Personal dictionary with word status tracking
• Works on YouTube, Netflix, TED, and any site with subtitles
It's free, no account needed, and takes 30 seconds to install.
I'd love to hear your feedback! What features would you add? What video platforms do you use the most?
Thank you for checking out Sublern! 🙌
