Hi everyone. I am built a small application on top of FSI German basic course and I need some feedback regarding it. It is a small web app. Currently only Unit 01 is available. I will feed in the rest of the units later down the road as I use it myself. Some of the features includes - Slow and fast audio with every single word and sentence in this app. You can play them with a click of a button. No need to rewind a tap back and forth. - Flashcards with keyboard control to quickly go through the material and drill them out. You can access the website at https://detawk.com/ .…

I recently custom prompted 1.5 pro to teach me new words by helping me to make sentences using them - the only way to learn vocab IMO. It's been helpful for my GRE prep, hope you may find it useful as well!

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.

I built a simple text-to-speech converter at texttospeech.site Free tier: 10 generations/day, standard voices, no account needed. Pro tier: Neural2 voices, 2000 chars, downloadable MP3s. Stack: Next.js, Google Cloud TTS API, Vercel. The $2 domain was an SEO experiment after my speechtotext.xyz satellite drove 22% of traffic to my main product. Curious if exact-match keyword domains still work for TTS searches. Feedback welcome — especially on voice quality and UX.
