大肚猴翻译 by belliedmonkey

BelliedMonkey Translator turns any web page and any video into a bilingual
experience.

WEB PAGES
Every paragraph keeps its original text with the translation directly below it,
in a distinct color. No tab switching, no losing your place.

VIDEO
YouTube, podcasts and video posts get sentence-matched dual subtitles — original
on top, translation below. Subtitles are translated ahead of playback, so they
never stutter mid-sentence.

BRING YOUR OWN AI
Google translation works instantly with zero setup. Prefer a specific model?
Plug in your own API key for ChatGPT (OpenAI), Claude, DeepSeek, GLM (Z.ai),
Qwen or Kimi — or any OpenAI/Anthropic-compatible custom endpoint.

PRIVATE BY DESIGN
No account. No tracking. No servers of ours in the middle — your keys and
settings stay on your device, and text goes straight to the provider you choose.
