New: Live Subtitles for anything playing on your Mac or iPhone, plus a conversation interpreter. Bilingual web pages, documents and review cards, all in one app.
BelliedMonkey Translator puts two languages on screen wherever you read, watch or talk — and the sentences you actually read come back as review cards.
LIVE SUBTITLES (APP)
Bilingual subtitles for whatever your device is playing. On Mac, the app listens to system audio and shows a floating subtitle bar that stays on top of any app, even full-screen video (macOS 26 or later). On iPhone, play a video or podcast out loud in any app, and a picture-in-picture window scrolls the original and the translation, sentence by sentence. Recognition happens on the device; Live Subtitles need iOS 26 / macOS 26.
CONVERSATION · LIVE INTERPRETER (APP)
Talk across a language gap. Both sides speak freely; each sentence is transcribed, translated and can be read aloud. Speech is recognised on the device, so the audio never leaves it. Requires iOS 26 / macOS 26.
SYSTEM TRANSLATION (IPHONE)
Select text in any app and tap Translate — BelliedMonkey answers with the engine you configured, in a small sheet, without leaving the app. Choose BelliedMonkey once in Settings › Apps › Translate › Default Translate App. Sentences you translate this way can go straight into your review deck. Requires iOS 18.4 or later.
WEB PAGES, SIDE BY SIDE
The Safari extension (also on Chrome and Firefox) keeps every paragraph's original text with the translation right below it. No switching tabs, no losing your place.
VIDEO DUAL SUBTITLES
YouTube, podcasts and web video get sentence-matched dual subtitles. No captions? Turn on AI transcript subtitles.
DOCUMENT TRANSLATION
Open a PDF, Word file or image and read it page by page, original and translation side by side.
LEARN AS YOU READ
Sentences you actually read can become review cards on a forgetting curve — read, listen and write practice, sentence notes and read-aloud. Optional sync lets your phone review what you read on your computer.
YOUR ENGINE, YOUR CHOICE
Bring your own AI service key, or any compatible endpoint.
PRIVACY, SPELLED OUT
Your keys and settings stay on your device. With your own key, text goes straight to the provider you chose and is not stored. Live Subtitles and on-device transcription never record audio. We send anonymous usage events (which features are used, never page content), and you can turn them off in Settings. No ads. The whole app is open source and free to download.
Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
· Browser extension · Fixed: When a YouTube transcript can't be fetched, the extension no longer retries the same request over and over — repeated requests are exactly what triggers YouTube's transcript blocking, which takes down even the native captions that still worked. At most 3 requests per video now, with a clear "subtitles unavailable" instead of a broken pipeline.
· App & browser extension · Fixed: When the network keeps timing out, translation stops by itself after 5 consecutive timeouts instead of retrying forever — tap "Retry" to resume. No more endless spinning.
· App (iPhone / iPad / Mac) · New: The first screen asks what you came for — "read web pages", "listen", or "both" — and picks the path to match; if you only want listening, it no longer pushes you toward the extension.
· App (iPhone / iPad) · Fixed: The "open the extension in Safari" banner no longer keeps coming back — one tap counts as asked; and an extension you already set up is no longer treated as missing just because it hasn't captured sentences yet.
· App & browser extension · Improved: Review opens without signing in; finishing a session ends more clearly (one graded card completes it); the hardly-used "check page" link is gone.
· App & browser extension · Internal: The entire UI layer now runs on React — same behavior, same look — so future interface work moves faster.
