Series browsing, precise timestamps & one-tap follow-ups
August 2026
Browse a video's whole series with one click. Tap the channel name above the player and you get the actual playlist the video belongs to (like a daily news series) — not a jumble of everything the channel ever posted. Works even when your link had no playlist in it: the app discovers the series automatically. "Load more" pages through the entire series.
Paste a playlist link, get the whole playlist. Drop a YouTube playlist URL into the search box and every video appears, ready to shadow. Playlist views get their own shareable link (aishadowing.net/?list=…) — send a curated series to a friend or your students, and it opens the same way on web and Android.
Share links carry your languages. When you share a video or playlist, the link now includes your learning language and native language. A friend who isn't signed in gets your exact setup — right subtitles, explanations in the right language, zero configuration. Signed-in users keep their own native language and just see the content in the shared learning language for that visit, without their account settings being touched.
Click a sentence, hear that sentence. Timestamps are now aligned to word-level speech timing, so tapping a sentence no longer plays the tail of the previous one. Human-made captions are also re-segmented into complete sentences instead of breaking mid-thought.
Suggested follow-up questions. After an AI explanation, the panel now predicts what you might ask next — tap a suggestion instead of typing. Works on web and Android.
Share links always show subtitles. Opening a video in a language different from your learning language now falls back to the video's own captions instead of a blank transcript.
Android polish. One unified AI explanation style with follow-ups, explanations respect your native language, explanation windows stack (newest on top), the keyboard no longer covers the input box, your library sorts by recently played, and videos resume where you left off.
Follow-up questions for AI explanations
August 2026
Ask follow-up questions after any AI explanation. Clicked a word, got the explanation, still confused? Now there's a chat box right in the explanation panel — ask for more examples, a comparison with a similar word, or why the grammar works that way. The AI remembers the context of your conversation. Works on web and Android.
Much faster page load. We parallelized how the app boots and stopped downloading resources you don't need. First visit is seconds faster; repeat visits are near-instant.
Smoother explanation panel. Dragging the AI panel across the video area no longer stutters.
Difficulty levels & personalized recommendations
June 2026
Every video gets a CEFR difficulty level (A1–C2), computed from real speech rate, sentence length and vocabulary — so you can pick videos that match your level instead of guessing.
Personalized video recommendations. Tell us your level and interests once; the home page suggests real YouTube videos worth shadowing, graded by difficulty.
Instant transcripts. Subtitles now appear immediately and are AI-refined progressively as you play — no more waiting for the whole video to process.
Redesigned Android app with bottom navigation (Learn / Library / Me), the same recommendation feed as the web, and share links that open directly in the app.
Your own audio, synced everywhere
May 2026
Import your own audio and video files (MP3, MP4, even ZIP batches) — transcribed right in your browser, with the same shadowing interface as YouTube videos.
Cross-device library sync. Sign in and your imported lessons follow you between browser and phone.
Natural text-to-speech playback for any sentence or word.
