Our verdict
Microsoft SwiftKey is a great free keyboard for prediction and swipe typing — but it has no AI writing tools. No tone change, no translation on-tap, no ask-AI, no rewrite. If you want a keyboard that genuinely uses AI to write better messages and emails, KeyAI is the upgrade. SwiftKey is for typing fast; KeyAI is for writing well.
