How does KeyTrans work?

KeyTrans is a keyboard extension for iPhone. After adding it as a keyboard and enabling Full Access, you choose an AI provider in AI Settings. You type your message, pick source and target languages, and use Send to insert the translation into the active text field.

Can KeyTrans replace the system translate option?

Yes. On iOS 18.4 or later you can set KeyTrans as your default translation app under Default Apps in Settings, then select text in a supported app and choose Translate.

Why does the keyboard need Full Access?

Full Access has to be enabled because translation requests are sent over the network to the AI provider you configure. If you want to translate photos without a connection, an optional local model can be downloaded.

KeyTrans itself is free to install and use as a keyboard. You supply your own AI provider, so any translation fees come from that provider and their privacy terms apply to the text you send.

KeyTrans - AI Translation Keyboard for iPhone について

Keyboard translation

Draft in the keyboard you already use, switch to KeyTrans to translate, then review and insert the result into the current field without leaving the conversation.

System translation integration

On iOS 18.4 and later, set KeyTrans as your default translation app and translate selected text straight from a supported app's share or translate action.

Photo translation

Open Photo Translation from the home screen, capture or pick a photo of a menu, sign or screenshot, and translate the recognised text. Offline photo translation needs the optional local model.

Bring your own AI provider

Choose the AI provider that powers translation in AI Settings and enter the endpoint, model and credentials that provider requires, so you control which engine handles your text.

Multilingual interface

The interface ships in around twenty languages, including English, Chinese, Japanese, Korean, Arabic, Hebrew and most major European languages.

KeyTrans is an AI translation keyboard for iPhone. You write in your usual keyboard, switch to KeyTrans to translate, review the result and insert it into the current text field. It also works as the system-wide default translation app on iOS 18.4 and later, and supports photo translation.

KeyTrans - AI Translation Keyboard for iPhone の効果的なユースケース

Multilingual communicators

Chat in another language

Reply in a language you do not write fluently without leaving the messaging app, since the translation is inserted straight into the text field.

Handle messages while abroad

Switch to the KeyTrans keyboard to compose a reply, check the translation, then send it — useful when you can read a language better than you can produce it.

Everyday users

Read signs and menus

Use Photo Translation on a restaurant menu, street sign or screenshot to get the gist immediately, with an optional local model for offline use.

Power users

Customise the translation stack

Configure your own provider endpoint and model, or set KeyTrans as the default translation app, to build a translation flow that matches how you already work on iOS.
