Transio vs BelliedMonkey Translator

AI translation, with more than one perspective. Transio brings AI language models, traditional translation engines, and system translation into one app. Compare translations side by side to find the wording and tone that fit what you are reading or writing. - Translate with AI: Connect language model services and, where supported, choose models and customize prompts to guide style and wording - Compare results: Send the same text to multiple services and see how their translations differ in terminology, tone, and phrasing - Make it your default: Set Transio as your default translation app, then select text in apps that support the system translation menu to translate with less copying and pasting - Build your own setup: Choose preferred languages, arrange services, set automatic or manual translation, and connect compatible APIs or local model services - Revisit translations: Keep source text and results from each service in your history for later reference and comparison Read an article, work through an email, or compare ways to express an idea. Choose the services that suit the task and keep their results together. Services and pricing Some services require your own API key or account and may charge separately. Local models require a service you set up yourself that is reachable from your device. Pro is a one-time purchase that permanently unlocks advanced app features, with no subscription. Third-party translation and model usage fees are not included.

Meetings, videos, documents — translated as you listen, processed only on your device; 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.
