ViewLingo: AR-style screen translator for Mac —offline & private

I'm Samuel, a solo developer from South Korea. I built ViewLingo because I got tired of the copy-paste-switch workflow when reading Japanese and English content on my Mac. I wanted translations to just appear on top of the original text — like subtitles for your entire screen. How it works: press a shortcut, drag a viewfinder over any text, and translations overlay right there. Works with browsers, PDFs, YouTube subtitles, Discord — anything on your screen. A few things worth mentioning: - Built entirely with vibe coding as a side project - 100% on-device using Apple's translation engine (nothing leaves your Mac) - Supports vertical Japanese/Chinese text - $4.99 one-time — no subscriptions, no free trial either (being honest here) This is not a VC-backed product or a full-time venture. I'm genuinely curious whether something I built this way can provide real value to people. If you work with foreign-language content on your Mac, I'd love to hear what you think — what works, what doesn't, and what would make it more useful for you.
