How to Get Two Subtitles on YouTube Simultaneously (In 58+ Languages)

By default, YouTube only lets you display one subtitle language at a time, and its auto-generated captions appear in broken two-word fragments. With Subkio, you can display both the original spoken language and your translated language simultaneously in full, natural sentences.

Key Advantages of Subkio vs. Native YouTube Player

True Spoken Audio Detection (Fixes Multi-Audio & Auto-Dubbed Videos)

Many YouTube creators now use multi-language audio tracks. Subkio inspects the player microformat and ASR tracks to lock onto the true original spoken language automatically.

JSON3 Complete-Sentence Reconstruction

Instead of scraping choppy DOM fragments, Subkio groups word timestamps into complete, grammatically natural sentences and pre-translates the next 5 sentences ahead of playback.

Interactive Word Lookup & Blur Listening Mode on Every YouTube Video

Hover over any word in the top subtitle to see its translation, or blur the bottom translation to test your listening comprehension.

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.
