A clean, distraction-free interface for shadowing practice: video, subtitles, loop controls, saved loops, and study tools in one place.
Features
Focused tools for learners who practice by listening, repeating, shadowing, and reviewing real subtitle lines.
Precision Timing
Fine-tune playback with small timing adjustments so a phrase starts and ends exactly where shadowing practice needs it.
A/B Loop Control
Set precise start and end points to create perfect practice loops. Master difficult phrases through targeted repetition.
VTT Study Mode
Study subtitles word by word with language-aware tokenization, read-aloud controls, meaning links, and dictionary lookup on Mac.
Saved Vocabulary
Save selected words with their subtitle sentence, timestamp, study language, meaning language, and dictionary summary.
Markdown and CSV Export
Export vocabulary as clean Markdown notes or CSV files for spreadsheets, review workflows, or Anki-style study.
Audio and Clip Export
Export your loop range as audio or a video segment when you want focused review material outside the app.
How It Works
Open a video, set your loop points, study the subtitle line, and save the words you want to review.
Interactive Sidebar Panel
Reopen recent videos, access saved loop segments, and keep repeat practice organized around the file you are studying.
A/B Loop Points
Set point A and B to create a loop. Use the precision controls (±0.5s, ±0.10s, ±0.01s) to fine-tune your loop range. Repeat difficult phrases until you master them.
Study and Export Vocabulary
Select words from VTT subtitles, read them aloud, save them with context, and export Markdown or CSV review files.
Quick Jump Controls
Navigate your video with precision using quick jump buttons. Skip backward or forward by 1s, 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, or 10s intervals.
