Built a free Chrome extension that turns streaming into language practice:

• 🎬 Works on Netflix, YouTube, Prime Video, Max (HBO), Disney+
• 🖱️ Click any subtitle word → contextual translation popup (knows the difference between "toast" the bread and "toast" the wedding speech)
• 📚 Dual subtitles (your language + target language side-by-side)
• 🎮 7 review modes: Quiz, Match, Type, Listen, Reverse + SRS flashcards (SuperMemo-2, like Anki)
• 🔥 Daily streak, 30-day heatmap, editable goal
• ✨ Optional Claude AI commentary on slang/sarcasm/idioms (bring your own API key)
• 🌍 UI in 7 languages, auto-detected from your browser
• 🔒 Zero servers, zero tracking, all data local. Open source, MIT licensed.

Free, no signup. Chrome Web Store:

Feedback welcome — especially edge cases on weird subtitle formats.

Hey r/AlphaandBetausers,

I just finished building Klar, a clean quit-smoking tracker for Android. Been working on it for a couple weeks and got it through Internal testing. Now opening up the beta for wider feedback before going public.

What it does:

• Live counter from your quit moment (days/hours/min/sec)

• 14 body-recovery milestones from 20 minutes to 15 years (sourced from ACS/NHS)

• Money saved at your pack price, in your currency (22 currencies supported)

• 12 achievement badges

• 4-7-8 breathing exercise for cravings

• Daily motivation, weekly recap — quiet hours respected, capped at 3/day

• 9 languages, OLED-friendly dark mode

Why I built it: most quit-smoking apps look like they were designed in 2014 and bury you in popups. Wanted something that feels like an Apple-grade app — minimal, fast, premium dark mode.

Privacy: nothing leaves your phone. No accounts, no analytics, no tracking. One small banner ad on home keeps it free.

Beta opt-in (Android only, free):

Looking for honest feedback — UI/UX issues, bugs, anything that feels off. iOS version is in TestFlight separately if anyone wants that link instead.

Cheers
