Side-quest building fluentsubs.com a #languagelearning app where you are in control of the content 🧠

Can you train a state of the art text-to-speech (TTS) model with little resources? It seems you can! I've used Google's free TPU research credit to train a Dutch version of "Dia" called Parkiet, a natural conversation speech model and the quality is on-par with ElevenLabs.

Any idea how to get a hold of Google's free Research TPU credits? I get these assigned for 30 days but there is either no capacity or the accelerator is not available at all #ml

Three other people have now surpassed me in all-time XP earned on my own language learning app! Great milestone. #buildinpublic #languagelearning

Got my first sale for Fluentsubs! Key things to make it happen:

- Shipped an awesome feature for beginner learners
- Made some exercises public to check out w/o an account
- Locked a lot of the features behind a "Pro" paywall and made it clear what the benefits are

Finished the Duolingo-like daily exercises for news content. You can try it out at app.fluentsubs.com/exercises/da... for 11 languages (will add more soon). Tomorrow I'll finally do some proper marketing and fix the membership option (basically everything is free) #buildinpublic #langsky

Videos with excellent transcripts can now be publicly shared! #buildinpublic

In a major upgrade to Fluentsubs I've added "cloze" for subtitles. Based on the accuracy of the transcript and the word length, random gaps are created as a listening exercise to the user to bridge the gap between reading/listening skills in a language. #buildinpublic #langsky

Fluentsubs made it to the Hackernews "Show HN" front! news.ycombinator.com/item?id=4290...

Now I suddenly have the problem of not being able to YOLO deploy because I have users 😅.

I've also shipped better transcription models, more feedback and a fine-grained control adding new words to a deck!

Fluentsubs just got smarter! 🚀 Now you can pick only the part that you need for your deck—perfect for short spaced repetition cards. Check it out! 📚✨ #LanguageLearning #buildinpublic

Foundation models are overhyped. SAM2 was hard to fine-tune and we got some great results after tweaking the training process a lot. Decided to give YOLO11 another try (even after the crypto miner debacle) and it seems to be on par with SAM2 in terms of quality and much much faster!

Had some nice feedback from the first users and implemented the playlist feature, and added some basic channels so beginner language learners are not completely overwhelmed. The videos are pre-transcribed so that they can be watched immediately! #langsky #japanese #buildinpublic

🚀 Just gave fluentsubs.com a complete makeover!
✅ New landing page – cleaner & easier to grasp
🎨 Fresh logo – friendlier & polished

I’d love to hear your thoughts! Put in a lot of effort to make everything super clear. #buildinpublic

Finished a complete overhaul of the spaced repetition implementation for my language learning app. Text input and hints are now available when rehearsing flashcards.

Still buggy on mobile 🤞 #buildinpublic

I ported Matt Might's bash scripts for detecting common issues in writing to a little web app (using Claude) and it's pretty fun to play with: simonwillison.net/2024/Dec/14/...

Streaks are now generally available. Also fixed some problems with the design. Next up is a complete revamp of the reward system to better analyse and track learning progress. #buildinpublic #langsky

The language practice chatbot still need some tuning to not sound like a manipulative stalker 😅. Not really the cozy vibe I'm trying to create for a language learning app. #ai
