ChatNPU vs Typeflow

ChatNPU Keyboard rewrites your text instantly in the style you choose. Select an identity, tap once, and you are offered a new version powered by on-device AI. Built for privacy, your typed and rewritten text stays on device. ChatNPU is available on supported devices with the required on-device AI capabilities.

TypeFlow puts AI directly inside your keyboard — so you can generate, rewrite, and clean up text in any app without switching windows or copying and pasting. HOW IT WORKS Enable the TypeFlow keyboard in Settings → General → Keyboard. Then in any app — Messages, Notes, Gmail, Slack, anywhere — tap the TypeFlow key to submit a prompt. The AI response is typed directly into the text field. VOICE PROMPTS Dictate your prompt instead of typing it. TypeFlow transcribes your voice, sends it to the AI, and inserts the result — all without leaving the app you're in. SNIPPETS Save frequently used prompts as snippets with a tap. Custom vocabulary ensures names and technical terms are always spelled correctly. ONE SUBSCRIPTION. EVERY APP. TypeFlow Pro unlocks unlimited AI in every app on your device. Monthly and annual plans available, with a free trial.
