Session memory and auto-vocab capture beat stateless chatbots, but Duolingo Max and Speak exist.

Word-level timestamps enable precise shadowing loops that Anki can't replicate.

Another feature I use a lot is selecting an audio fragment, sending a predefined prompt to an AI to "explain grammar" or "explain nuances of meaning" and I still experimenting with prompts.
And because shadowing is so easy I also use it as a player to improve my English pronunciation. (I am not a native English speaker.)
I made a quick video showing the workflow for creating Anki cards and shadowing: https://youtu.be/TaR58uuDBvU?si=o5aGLAi2S-BZ7Zy9
The app supports 15 input languages (Japanese and Chinese are the latest experimental additions), and more than 30 output languages.
I would really appreciate it if you could try it https://lingochunk.com/try. I know there are other tools with similar functionality but I created something that fits my workflow and it is fun to build.
Also I struggled to find public domain audio for the try page. I'd be grateful if anyone could point me to public domain sources (I used LibriVox, Wikimedia and FSI courses), or if you're a creator, let me feature some of your own recordings with credits and links.

AI stories at your JLPT level when Duolingo's fixed curriculum misses intermediate learners.
Yet another transcription wrapper when Otter, Descript, and Firecrawl already dominate.
Clean language learning app but Readlang and LingQ already do this.
Timestamps every web extraction for agents—solves real AI hallucination failure mode.
