Local AI Live Translate v1.4.0

What's new in 1.4.0

A roomier popup that fits every UI language, and language menus you can search.

• Searchable language menus. The video, subtitle and UI language menus have a search box pinned to the top of the list. It matches exact text, letters in order and small typos ("japnese" finds Japanese). It also recognises each language's English name, its own name (日本 finds Japanese) and common aliases such as Bengali, Tagalog, 粵語 and Mandarin. Languages are listed A–Z in the popup's own language, and you can open a menu by pressing Enter or by starting to type.
• Consistent, compact dropdowns. Every other dropdown now opens the same rounded menu as the language menus, with a check mark on the current choice, in all seven themes. The font menu shows each font in its own typeface. This uses Chrome's customisable select, so it needs Chrome 135 or newer; older versions keep the plain system list.
• A wider popup: 400 px, up from 360. Nothing wraps, gets cut off or shifts in any of the 10 UI languages:
  • The UI Language label now has a globe icon instead of an English "(UI Language)" suffix.
  • The Profile and Display Config buttons moved up beside their titles, so those dropdowns are full width.
  • The German, Spanish, French and Russian taglines are shorter and closer to the English.
• README: new translation model comparison. Hy-MT2-7B, Hy-MT2-30B-A3B, MiLMMT-46 (12B and 4B), Gemma-4-12B and Qwen3.5-9B, measured across 39 language pairs. Hy-MT2-7B is still the recommended model.

To update, replace the old folder with this one (or run git pull on a clone), then reload the extension in chrome://extensions.
