Is any AI keyboard 100% free?
Short answer: not really. Every AI keyboard worth using talks to a paid AI model (OpenAI, Anthropic, or a similar provider) — and someone has to pay for those API calls. The keyboards you'll find on the App Store fall into three buckets:
- Truly free, but limited. Apple's built-in keyboard plus Apple Intelligence Writing Tools on iPhone 15 Pro and newer. Free, no subscription — but no translation, only 3 tone presets, and you need an eligible device.
- Free download + paid AI features. Grammarly Keyboard is free for spell-check and basic grammar. Tone change is behind Premium ($5.83+/month).
- Paid subscription with a free trial. KeyAI, CleverType, TypeAI, Keybot. The trial period is the genuinely-free portion.
If you want every AI tool — grammar, tone, translation, AI replies, paraphrase, ask AI — there is no fully-free option in 2026. The best "free" entry point is a trial.
