Two subtitles, kept tidy.
Learning line first. Familiar line underneath. Stable sizing, readable contrast, no floating translation soup.
Dual subtitles. Minimal theater.
Dubstack.
For watching in another language without turning the night into homework.
Free is not decorative. Premium is for the odd line that needs backup.
preocupes
worry, more or less
No te preocupes por nada de eso
Do not worry about any of that
Product
Watch, pause less.
Dubstack puts the line you are learning above the line you know. Click the part that slipped by. Then keep watching.
Click the awkward bit.
Words and dragged phrases open in a small panel inside the video. A dictionary tab is not invited.
Replay the line.
Alt-R repeats the current cue. Useful, unfortunately.
Premium explains the weird parts.
Idioms, grammar turns, and context when the literal translation is technically correct and still not helpful.
Save it.
Keep words with the original subtitle line. Export to CSV or Anki when future you starts asking questions.
Netflix and YouTube, desktop Chrome.
The first release stays narrow on purpose. Reliability beats collecting logos.
Privacy
Free stays local.
Settings, saved words, and free lookups live in Chrome extension storage. Premium sends the selected phrase, nearby subtitle line, and language pair so the explanation has enough context. Not your watch history.
Pricing
Free is the point. Premium is the escape hatch.
Most lines should not require a subscription. Some lines are rude about it.

FAQ
Small print, normal size.
Is Dubstack affiliated with Netflix or YouTube?
No. Dubstack is independent and is not affiliated with Netflix, YouTube, or Google.
Does it collect my watch history?
No. Premium requests include only the phrase you asked about, its subtitle context, language codes, and access data.
How do I cancel?
Subscriptions are managed through the billing portal. Free features keep working after cancellation.
Why is the launch scope so narrow?
Because subtitles break. Dubstack is choosing reliability and polish over a long checkbox list.
