In plain words
AI Shadowing converts YouTube videos into interactive language lessons using shadowing, a technique where learners repeat spoken content. Users paste a video link to get sentence-by-sentence transcripts that can be clicked to loop and replay, and tap individual words for instant AI-generated grammar explanations in their native language. The tool is free, requires no signup, and works on web browsers and Android devices. It was created by a self-taught German learner who used the shadowing method to progress through language levels.

Android app available, iOS coming. Hi — I'm Xiling. I built this tool because I needed it for myself. I'm a self-taught German learner. After getting through the basics with a textbook (A0 to A1), I started shadowing YouTube videos in German — repeating natives, sentence by sentence, half a second behind them, matching their rhythm and intonation. In about 3-4 months of part-time practice (30-45 minutes a day) , I went from…from aishadowing.net

- ADAI dub tool I made to watch foreign language videos with my 7-year-old2024 · speakz.ai · ▲348
Hey HN! I love watching YouTube with my 7-year-old daughter. Unfortunately, the best stuff is often in English (we're German). So I made an AI tool that translates videos directly, using the original voices. All other sounds, as well as background music, are preserved, too. Turns out that it works for many other language pairs, too. So far, it can create dubs in English, Mandarin Chinese, Spanish, Arabic, French, Russian, German, Italian, Korean, Polish and Dutch. The main challenge in building this was to get the balance right between translating the original meaning and getting the timing…

- LLLanguage Learning from YouTube content2025 · fluentsubs.com · ▲40
Hi! I'm living as an expat in France and I had a hard time following the news. So I've been working on Fluentsubs that turns YouTube content into a language learning experience. YouTube videos up to 20 minutes can be transcribed and listened to. At the same time I made it easy to lookup certain words and automatically add spaced repetition cards using the given context. This means that you can also rehearse with a real voice and not with AI dubs. This works especially well for the somewhat smaller languages that have a small track on Duolingo, and now are desperately looking for content…
Turn native language audio into flashcards and shadowing practiceJun 2026 · lingochunk.com · ▲92Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai



Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
