Review, then use it
Select the result that fits. You decide what to insert, play or send.
About voice sharing: TalkCos previews synthesized audio. The documented chat-app workflow plays it through the speaker for recording in the chat app; it does not directly insert audio into another app.
Built for personal conversations
Useful AI. Clear choices.
You stay in control
Review AI suggestions before using them. Generated text can be inaccurate or miss context.
Permission with a purpose
Cloud features need internet access. The keyboard setup explains Full Access; see our privacy policy for data handling.
Chinese & Korean first
App interface language and keyboard content language are separate settings, so you can choose the experience that suits you.
