Products that do what Turn native language audio into flashcards and shadowing practice does
Here 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…

I've been learning Japanese for a few years and kept running into a similar problem. I'd find a video I wanted to learn from, hear a useful sentence, and then realise that turning that sentence into something I could study later was both time consuming and draining at times. I would end up jumping between a video player, subtitles/transcription, a dictionary, screenshots, audio clips and Anki. So I built SubSmith to bring that workflow together. You can drop a video or audio file into it, generate a transcript locally and then use the transcript alongside the media to: * look up words…

Hey HN, this is my first product launch. I built You2Anki along my language learning journey to aid my vocabulary from any content I want. Most tools I tried weren’t particularly made for language acquisition. You2Anki was designed with that focus in mind. Simple, intuitive and distraction-free. I hope it helps you!

Hi HN, I have been studying languages as a hobby for a large portion of my life. Hence, I decided to create a spaced repetion app with the techniques that have helped me the most so far. It's aims to be made simple for the regular user to plug and play. I'd love to hear your feedback!

Hello everyone. I built an AI-based toolset to help me with language learning. I wanted to be able to easily generate very specific study content and get rapid feedback on my writing. Unlike most language apps, it doesn’t actually try to teach you a language. Instead, it’s a collection of tools for people at an intermediate level who already have a learning process It’s particularly great for Anki users. There a demo video on the login page, and I set up anonymous auth for people who want to test it without creating an account. Feedback and bug reports welcome.

Hey HN! I built Transcrib.ee to help me generate transcripts for lectures on YouTube with no captions, especially multilingual lectures. I was constantly frustrated with videos that had no transcripts or inaccurate ones, so I built a tool and decided to share it with everyone. This tool uses Groq (an AI inference engine that's different from Grok and offers very fast processing) and OpenAI's Whisper model (really accurate in multilingual) to quickly transcribe any YouTube video, regardless of the language. It's been a game-changer for my studies! To make it even faster, I created a Chrome…

It makes it easy to hit API's, web scrape, do text-to-speech via online services etc in order to build rich flash cards in an automated way. This has grown organically over a couple of years while learning French and German with some friends and thought some of you guys might find it useful. An example pipeline I built with Hanky: - Use CV to grab highlighted words and their context off of a page of printed text (extract) - translate the highlighted word via an API (transform) - generate audio with a tts service (transform) Then load all that into anki as flash cards (load) Keen to hear any…

Hey HN, I have been working in the last weeks on the task of automatically extracting a table of contents from a raw (audio or video) transcript, aka a 'chaptering' task. That turned out to be more difficult than I inially thought, especially because I needed to keep the timestamp data, and because I had to deal with long transcripts, and LLMs tend to 'forget' part of input data when it is too long. I was also surprised that I could not find any open-source solution for that, in standard libraries like Langchain or LLamaIndex, despite the wide range of possible use cases (text summarization,…
