Changelog

July 2026

v1.0.1

Premium now activates this browser automatically after checkout. Explanations open in one click and render emphasis cleanly instead of showing formatting marks.

Reliability pass

Improved YouTube auto-caption timing and caption handoff. When Dubstack turns captions on, switching Dubstack off now reliably turns them back off unless you changed CC yourself.

v1.0.0

Dual subtitles, phrase lookup, one-key replay, saved lines, and export launched for Netflix and YouTube.
