Dollim: YouTube Shadowing
Finally hear English. Free
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Years in, still glued to subtitles? You hear it but it won't click. Loop what you miss, say it back, ask the AI. Keep going and it clicks — no subs. Paste a YouTube link.
That one sentence you tried to catch — and missed?
Most listeners just keep going. Then they miss the next sentence too. And the next. They finish the video knowing roughly what it was about, without ever really hearing it.
Dollim takes a different approach: if you can't hear it, loop it. Five times. Twenty times. Until every consonant lands. Then say it back and compare with the original by ear. And when a line still won't click, ask the AI. Loop it, say it back, ask the AI — keep that small loop going and you start to hear it, without subtitles.
— Made for you if
• You watch YouTube lectures, interviews, or news in your target language and want to keep up
• Fast movie or drama dialogue leaves you behind
• You want subtitle-free listening but don't know how to train for it
• You're done with passive replay and want deliberate practice
— Core features
• Loop just the part you missed
Pinch the A/B start and end of any clip on a carousel timeline, down to 0.25 seconds. The hard part, on repeat, until every word lands.
• Half speed, voices still natural
Slow fast talkers to 0.5x — the pitch stays put, so nothing turns to mush. You finally catch the sounds you used to skip past.
• YouTube + your library
Paste a YouTube link or import any video or audio file from your phone. Podcasts work too.
• Discover — ready videos to practice with
A dedicated tab of hand-picked videos in your study language, grouped by topic: Interviews, Talks, Conversations, and Lessons. No more hunting for something to study — open it and start.
• Record & compare (shadowing)
Record your own take of a loop, then play it against the original and compare by ear. Shadow a line until it sounds right to you. No scores, no grading — just your ear, getting sharper.
• Save loops (up to 10 per session)
Keep favorite passages with custom names. One tap to re-activate.
• Captions — in the video's original language
YouTube renders the video's native track. Device files show embedded captions or external SRT files. Three caption-size presets.
• Long-press caption translation
Tap and hold any caption phrase for an instant translation. Save the ones worth remembering. Free users get 10 translations per day.
• Notes
Saved phrases live in one place, with their translations, ready for review.
• Lock screen controls (device files)
Listen with earbuds and skip ±15 seconds without unlocking.
