24 alternatives to Vocab extractor for language learners using Stanza and frequency ranks
I'm building a Telegram bot to practice Dutch. GPT-4o-mini kept picking vocabulary words I already knew, so I built a classical NLP pipeline to do it instead. It takes a short text + learner level (A0–B1) and returns the best words to study, using Stanza for parsing and corpus frequency ranks (SUBTLEX-NL, srLex, SUBTLEX-US) for scoring. Wins at A1/A2, loses at A0 where the LLM picks more obvious words. I also tried adding multi-word phrases (ADJ+NOUN, VERB+NOUN, phrasal verbs) backed by NPMI-scored collocation whitelists. Couldn't beat GPT there because it just "knows" which phrases…

Hi HN — I built Vocab Top because I kept looking up the same words over and over and never retaining them. Dictionary definitions weren't sticking. The idea: use generative AI to surround every word with multiple memory anchors — a custom image, a mnemonic trick, example sentences, native audio, and grammatical forms — so your brain has more to hold onto. Tech stack: Next.js 16, React 19, Tailwind CSS. The AI generation uses Google Gemini and FriendliAI. Audio is Google Cloud TTS. Words are saved to local storage — no account required. The newest feature is Word Forms: when you search any…

PrompTessor▲125After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live. As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor. This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And…

My puny version of ChatGPT. This was based on the excellent LLM lecture series by Andrej Karpathy: https://www.youtube.com/watch?v=kCc8FmEb1nY The main points of differentiation are that my version is token-based (tiktoken) with code to load up multiple text files as a trining set. Plus, it has a minimal server which is a drop-in replacement for the OpenAI REST API. So you can train the default tiny 15M parameter model, and use that in your projects instead of ChatGPT. I trained it on 20Mb of Project Gutenberg encyclopaedias, then fine-tuned it on 120 dad jokes, to get a Q: A:…

i needed a vocab app that worked offline with spaced repetition built in. the options out there either required an internet connection, didn't have spaced reptition, or has ads. deft ships the entire English Wiktionary (~1.1M words) on-device. the raw Wiktionary dump is ~18GB of JSONL — i stripped it down to just the basics (glosses, parts of speech, related words) and compressed it into a ~220MB SQLite database for definitions and a ~34MB Tantivy search index. next release should bring the total size down to ~100MB, just finalizing that. search runs three tiers via Rust: full-text search…

PolyglotGPT▲15Hi HN! I'm trying to learn a language, but I don't have anyone to speak it with, so I made this website to get some practice. To start, all you have to do is set your native language and target language. Then, just start talking to it in either your native or target language. It'll catch any mistakes you make when you speak in your target language and answer any grammar/vocab questions you have. It has a translate button, a romanize button (converts any text into the Latin alphabet), and you can highlight words/phrases you don't know in AI responses to have them explained. I'd…
