Frequently Asked Questions

How does Subkio display two subtitles at once on YouTube and Netflix?
Subkio overlays two customizable subtitle tracks directly inside the native YouTube and Netflix video player. Subtitle 1 displays the original spoken language (or a translation), while Subtitle 2 displays your target translation language simultaneously.
Do I need to create an account or log in to use Subkio?
No. Subkio works immediately after installation without requiring any email registration or Google login. All your settings and saved phrases are stored locally in your browser.
How do I activate my Subkio Pro license key after purchasing?
After purchasing Pro Monthly, Pro Yearly, or Pro Lifetime, you receive a license key by email. Click the Subkio icon in your browser toolbar, open the 'Pro License' tab, paste your key, and click Verify to unlock unlimited access immediately.
How does Subkio fix choppy YouTube auto-generated captions?
Standard YouTube auto-captions often appear two words at a time and break sentence structure. Subkio's Complete-Sentence Engine reads the underlying JSON3 caption timeline, detects the true original spoken audio language, and merges fragments into smooth, natural sentences.
What is your refund and cancellation policy?
You can cancel monthly or yearly subscriptions at any time in one click. In addition, all first-time Pro purchases are backed by a 14-day money-back guarantee. Simply contact support@subkio.com.
