BelliedMonkey Translator

Most translators stop at the translation. BelliedMonkey Translator keeps going: read the web and watch video bilingually, and the sentences you actually read come back as review cards on a forgetting curve. Free, open source, and no servers of ours in the translation path. WEB PAGES, SIDE BY SIDE Turn on translation and every paragraph keeps its original text with a fresh translation right below it, in a distinct color. No switching tabs, no losing your place — just read. YOUTUBE DUAL SUBTITLES Watch with the original subtitle on top and the translation underneath, matched sentence by sentence, so you can follow along and pick up the language as you go. LEARN AS YOU READ Sentences you actually read can become review cards on a forgetting curve — read, listen and write tiers, free practice, sentence notes, and read-aloud. Off by default, and everything stays on your device. SYNC ACROSS YOUR DEVICES (OPTIONAL) Sign in with a free email account and your phone can review what you read on your computer. What sync stores on our servers: your saved sentences and translations, their source page URL and title, and review times — in readable form, only for your account. Delete a source or your account and it is removed from all devices. Without signing in, nothing leaves your device. BRING YOUR OWN ENGINE Google translation works instantly, with no setup. Prefer an AI model? Add your own key for OpenAI, Claude, DeepSeek, or GLM and translate with the engine you trust. You're always in control. PRIVATE BY DESIGN No tracking, no telemetry, no ads. No servers of ours in the translation path — text goes straight to the provider you choose, and your keys and settings stay on your device. No account unless you want one. The entire app is open source. FREE AND OPEN BelliedMonkey Translator is free and fully open source. Great for reading foreign news and blogs, studying a language, following creators who speak another language, and browsing the global web the way you'd browse your own.
