Upload a podcast, video, lesson or subtitle file and EchoDeck builds a personal speaking course — timed shadowing drills, smart flashcards, pronunciation scoring and spaced repetition, from the content you already enjoy. Teachers & creators can share decks with their audience.
No signup to try · No credit card required · Free plan included
From raw recording to a polished, repeatable study deck — in minutes.
Paste a YouTube link to pull its captions, drop in SRT/VTT subtitles, or use timestamps or plain text. Each line becomes a flashcard with a real audio shadowing loop.
Imported videos play right inside your deck — every card's loop jumps the real video to that exact sentence and pauses when it ends.
No audio? Your browser's built-in voices read any card aloud in its language — so even pasted text becomes listening practice.
Loop each segment at adjustable speed, then review with an SM-2 scheduler that surfaces exactly what's due.
Record yourself and get word-by-word feedback right in your browser — the score is how closely your words (or characters, for Japanese/Chinese) match the target sentence, plus a suggested review grade.
One click fills a card's back with a natural translation plus a short grammar note and example — or auto-fill an entire deck at once.
One click turns sentences into fill-in-the-blank cards for active recall — editable any time.
Track retention, streaks, daily activity, and a 7-day due forecast so momentum never slips.
Publish decks to a public, searchable catalog — or install community-made decks into your own workspace in one click.
Publish any deck to a clean public link — your followers study and export without seeing your schedule.
Invite teammates by email with admin / editor / viewer roles and collaborate on the same decks.
EchoDeck works as an installable app on your phone or desktop, with push notifications that nudge you when cards are due.
