Common questions.
Does LTAI really work on Netflix and YouTube?▼
Yes. LTAI captures the audio your Windows PC plays — it doesn't matter which app it comes from. Netflix, YouTube, Twitch, Discord, games, Zoom calls, browser tabs — anything that makes sound, LTAI translates.
Is the free plan actually free?▼
Yes. 15 minutes of live translation per day, every day, forever — no credit card required, no trial expiring. Plus 1 free snip translation per day and 2 free read-aloud plays per day. Upgrade only if you need more.
How accurate is the translation?▼
LTAI uses OpenAI's latest models — Whisper for transcription and GPT for translation. Quality is excellent for major languages. AI translations can occasionally make mistakes, but they're accurate enough to follow any content comfortably.
Does LTAI work on Mac or mobile?▼
Windows only for now. A browser extension is on the roadmap (works on any Chrome browser including mobile), followed by Mac and native mobile apps.
Is my audio safe?▼
Yes. Audio is processed in real time and discarded immediately. Nothing is stored on disk or sent to LTAI servers. The only data we keep is your account email and subscription status.
