Frequently Asked Questions
Are AI keyboards secure to use with sensitive information?
Security varies by keyboard. CleverType and KeySmart AI offer end-to-end encryption and offline modes for sensitive data. Always review the privacy policy of your chosen keyboard and look for options to disable cloud processing for sensitive information. Most premium keyboards now offer robust security features, but free options may process more data in the cloud.
