LTAI adds live translated subtitles over videos, streams,meetings, games and more on Windows. Built to reduce delay, block hallucinations and make foreign content understandable in real time.
Hey Product Hunt!
I built LTAI because I kept running into the same wall,
great content exists in Japanese, Korean, Spanish, French...
but subtitles don't always exist for it.
Anime before the official translation drops. Korean streamers
on Twitch. Japanese documentaries. Games with no English dub.
International Zoom calls. LTAI handles all of it, live AI
subtitles as an overlay on your Windows screen, in any language,
for anything your PC plays.
No browser extension. No setup. Just press Start.
What makes it different:
→ Captures system audio directly (works on Netflix, YouTube,
Twitch, games - anything)
→ OpenAI Whisper + GPT with context memory for natural translations
→ Visual snip - drag a box around any foreign text on screen
for instant translation (manga, game menus, signs, social posts)
→ Customizable overlay — position it anywhere, toggle what you see
→ Free plan: 15 min/day, no credit card required
We already have users in South Korea, Australia, France, UK,
Norway, Poland, Ukraine and more - all found LTAI organically
before this launch.
Would love your honest feedback. Happy to answer anything. 🙏
Does this actually work on live twitch streams? I always assumed the latency would make it unwatchable.
@justinnapp Yes — Twitch works great. The latency is
1-2 seconds on average which sounds like
a lot but in practice feels natural, similar
to how live TV subtitles work. You adjust
within a minute of watching. Tested it on
Japanese and Korean streamers extensively.
v1.8 (next): customizable hotkeys, translation history export
as SRT/VTT files, source language picker, context modes
(Anime/Gaming/News/Business)
v2.0: Browser extension (Chrome/Edge/Firefox) — works on
any web video, any device with a browser
v2.5: Mac desktop + Voice Mode Beta (Ultra plan) — live

Building this solo and shipping fast. Every version ships
within weeks, not months.
