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.
