The AI keyboard for creators
TikTok hooks, Instagram captions, X threads, LinkedIn posts, YouTube descriptions — all generated and polished from the same iPhone keyboard.
Content creation is mostly typing — and the same idea needs to be reshaped for each platform. An AI keyboard removes the friction between "I have an idea" and "I have 5 platform-shaped versions of that idea".

Write the long version. Tap *Paraphrase → TikTok hook*, *→ Twitter thread*, *→ LinkedIn post*. Reshape without rewriting.

FAQ
Can an AI keyboard write captions for me?
Yes — both from scratch (Ask AI / Generate) and as polish (Tone, Paraphrase). The best content creators use AI as a starting point and edit in their voice.
Does it work in TikTok, Instagram, and YouTube apps?
Yes — every iOS app. The keyboard sits at the OS layer.
Is the content original if AI helped write it?
Same as any writing assistant. The AI helps you polish, paraphrase, and generate variations — the ideas, judgment, and creative direction are yours.
How does it compare to Jasper or Notion AI for creators?
KeyAI is on your iPhone, in every app. Jasper and Notion AI are desktop-first long-form tools. Most creators use both — AI keyboard for the 30-second draft, dedicated tool for the 30-minute deep work.
