Good to know
How do I subscribe?
Add sublingo to Chrome, sign in with Google, and pick a plan right in the extension panel. Checkout is handled by PayPro Global; your plan unlocks the moment you pay.
Can I cancel anytime?
Yes — no questions asked, via the customer portal. Your plan stays active until the end of the paid month, then drops back to Free.
What about live audio translation?
Every paid plan includes the live-audio engine, which turns any live stream's speech into translated subtitles in real time. Live transcription runs on your own Soniox key, pay-as-you-go — you only pay for what you stream.
Is there a limit on the Smart plan?
Smart runs your first 50 videos each month on our best model, then continues on the fast Standard engine for the rest of the month — you're never blocked mid-binge.
Is there a one-time option?
Yes — a $99 one-time payment unlocks the full engine forever with your own OpenAI API key: pick any OpenAI model in the dropdown and pay OpenAI directly for what you use (a few cents covers hours of subtitles). Best for power users who already have an API key and don't want a subscription. Available inside the extension.
