Manabig Offline Translator

Like having an interpreter right there with you.

Continuous mode lets you talk without pressing the recording or translation button for each utterance. Start it once. About one second after speech stops, the app translates and reads aloud. When playback finishes, listening starts again automatically. Wait for playback to finish before speaking again. Available for any selected pair of Japanese, English, Mandarin Chinese and Korean.

Optional high-quality AI translation supports 23 languages. After preparing the required models and supported offline voices, recognition, translation and playback run on your device without an internet connection.

Start the free trial yourself to use high quality for one month. There is no automatic charge or monthly fee. Standard translation remains available after the trial ends. Continue high quality only if you choose a one-time purchase (JPY 480 in Japan; confirm your local price in Google Play).

Make yourself understood, by voice or by typing. Manabig Offline Translator helps with face-to-face conversations and written translations on Android. Choose two languages, hold the microphone button to speak, and release it to translate. The original text, translation, and conversation history stay together on one screen.

When speaking is difficult or you need to keep quiet, type your message and choose its translation direction. Speech playback is available for supported languages and devices. If playback is unavailable, the translated text remains on screen to read.

Automatic direction detection works for language pairs drawn from Japanese, English, Mandarin Chinese, and Korean. For other pairs, change the speaking direction manually. This feature does not apply to every available translation language.

Standard translation supports 58 languages. The optional high-quality mode uses a larger model on your device and supports 23 languages. These are text translation counts, not a promise of voice input, speech playback, or automatic direction detection in every language. Speech features depend on the language, phone, and installed language packs.

Prepare for offline use by downloading the required models and language packs first. Supported recognition and translation can then run locally on your Android device, including without a network connection. Initial downloads, purchases, purchase restoration, and updates require internet access.

High-quality translation is a one-time in-app purchase for this app. Check the purchase screen for your local price. This purchase applies to Manabig Offline Translator and is separate from the high-quality option in Manabig Live Translation.

Prepare for travel, serving international customers, and places with weak reception, such as aircraft cabins or underground areas. Download the required models in advance to translate offline. Type when speaking is inconvenient or speech recognition gets a word wrong. Translations remain visible as text; speech playback is available for supported languages and devices. The high-quality model may take longer to load the first time. Processing time varies with text length, device performance, and the available GPU or CPU backend.
