What's New

Discover how Subtiltee gives you flexible language-learning tools that already work across many of the streaming sites you use.

🚀 What's Next

Here's what we're working on to make Subtiltee even better:

  • 🎯

    Advanced Vocabulary System

    Smart flashcards with spaced repetition for words you encounter while watching

  • 🌍

    More Platforms

    Expanding support to Apple TV+, HBO Max, and more streaming services

  • Performance Improvements

    Faster subtitle loading and smoother synchronization across all platforms

v1.9.0July 6, 2026
NEW

New "My Permissions" page — decide which sites Subtiltee can run on, right inside the extension. Grouped per-platform toggles with Enable all / Disable all, so you no longer have to hunt through the browser's site-access list.

IMPROVED

Privacy first: authorize only the sites you actually watch on (e.g. just YouTube) instead of every site at once. Turn any platform — or even a single regional Prime Video domain — on or off in one click.

NEW

More reliable subtitles on native platforms: if a platform's built-in subtitle route breaks (player update, encrypted manifest…), Subtiltee now catches the subtitles still flowing on the network and offers them in a clearly-tagged fallback view.

IMPROVED

Better YouTube subtitles — added json3 track support for cleaner text and more accurate language names.

v1.8.0May 13, 2026
NEW

Apple TV+ is now natively supported — subtitles, AI explanations, and learning tools work directly in the Apple TV+ player.

NEW

New fixed video position option keeps the player anchored where you want it, so subtitles stay in a comfortable reading spot.

NEW

When merging two subtitle tracks (dual subtitles), you can now choose how lines align for a cleaner side-by-side display.

NEW

Disney+ now also works on the new apps.disneyplus.com player URL, in addition to the classic disneyplus.com domain.

IMPROVED

Typing in Subtiltee's input fields no longer triggers the underlying platform's keyboard shortcuts (e.g. play/pause, seek).

IMPROVED

After syncing or seeking, the current subtitle reappears instantly instead of leaving a brief blank overlay.

IMPROVED

Exiting fullscreen on HBO Max is now more stable, with no more lost subtitles or broken overlays.

v1.7.0March 31, 2026
NEW

Universal Fallback now expands compatibility beyond native integrations, helping Subtiltee work on many more websites (with permission).

IMPROVED

Unsupported-site activation is now simpler, so you can enable Subtiltee quickly and use it when needed.

IMPROVED

Universal subtitle detection is now more stable and dependable across a wider range of sites and playback contexts.

IMPROVED

A smoother unsupported-sites experience means fewer missed subtitle tracks and more consistent learning.
