Free AI Keyboard Privacy Notes
Keyboard apps can see what you type in ordinary text fields. AI features may send text, voice, or usage data to cloud services. Full Access is an iPhone keyboard setting; Android instead uses input-method, microphone, and sometimes accessibility permissions. Review each feature and keep sensitive text out of cloud AI unless you trust the provider's policy.
Check the feature, not just the price
On your phone, try one short message in each language you use, one dictated paragraph, and the writing tool you need. Check whether it requests sign-in, a paid plan, or extra permissions. Keep the free option if it solves your task without more cleanup. Sources checked October 15, 2026: SwiftKey Copilot changes, Translator platform support, and Grammarly for Android.
