FAQ
This is backed by real science. Telflix uses spaced repetition (the same algorithm behind Anki) and contextual learning — studies show vocabulary learned in context is retained 2-3x longer than from word lists. You learn from real content, practice with exercises, and review with spaced repetition.
Your first lesson is free with no account needed. After signing up, you get 5 AI lessons, 25 exercise checks, and unlimited word translations per month — all free.
Most YouTube videos have auto-generated subtitles. If your video doesn't have English subtitles, you can upload your own video file with an .srt subtitle file.
Telflix teaches English. Your native language can be set to Russian, Spanish, Turkish, or Arabic — exercises and translations will adapt to your language.
