As answered by people managing Opalstack and SkoolTranslate.
SkoolTranslate's answer:
Chrome Extension
SkoolTranslate's answer:
109 languages - 10x more than competitors like YouTube Translate (10 languages). One-click install, works in real-time directly on the video player. No copy-pasting subtitles to external tools.
SkoolTranslate's answer:
Free tier (5K chars/month), affordable pricing from $2.99/month, 109 languages, and support for 13+ video platforms including YouTube, Udemy, TED, and Skool. Competitors either limit languages or charge significantly more.
SkoolTranslate's answer:
Language learners, students taking international online courses, professionals consuming educational content in foreign languages, and anyone who watches video content across language barriers.
SkoolTranslate's answer:
Built to solve a real problem: millions of people watch educational content in languages they don't fully understand. Instead of manually translating subtitles, SkoolTranslate does it instantly in-browser. Named after Skool.com (one of the first supported platforms), now expanded to 13+ video sites.
SkoolTranslate's answer:
• Language learners on YouTube and Udemy • Skool.com community members • International students in online courses • TED Talks viewers across non-English speaking countries
