Why Standard YouTube Auto-Captions Fail Language Learners
Native YouTube auto-captions display choppy 2-word fragments and often translate from the wrong audio track. Subkio rebuilds natural sentences in real time.
Standard YouTube Auto-Captions
[we never] ... [really notice] ... [how fast]
Choppy word-by-word fragments break grammar and context, making accurate translation impossible.
Subkio Complete-Sentence Timeline
On ne remarque jamais vraiment à quel point le temps passe vite.
We never truly notice how fast time passes.
Subkio merges JSON3 word streams into complete, grammatically accurate sentences and pre-translates 5 cues ahead.
Mehr als nur zwei Textzeilen
Every tool you need to turn passive video watching into effortless daily language acquisition.
Blur-to-Reveal Listening Mode
Keep Subtitle 2 blurred while listening to the original audio. Simply move your mouse over the subtitle whenever you need to check the meaning.
1-Click Word & Phrase Dictionary
Hover over any word in Subtitle 1 for an instant translation tooltip. Click 1 to 3 words in a row to save idioms and multi-word expressions.
Smart Auto-Pause on Hover
Never miss a fast dialogue line again. Subkio automatically pauses playback when your cursor enters the subtitle and resumes when you move away.
Inline Floating Video Toolbar
Save phrases, adjust font size (A- / A+), cycle background opacity, or toggle blur directly on the video without opening the extension popup.
Saved Vocabulary & 1-Click CSV Export
Review all your saved words and sentences inside the popup and copy them to your clipboard or export a clean CSV file for Anki, Quizlet, or Excel.

Everything You Need to Know About Subkio
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.
