Our verdict
Ghostwriter is built around AI-generated text and replies — that's where it shines. KeyAI does that plus translation in 55+ languages (Ghostwriter is English-focused), more languages, and integrates grammar + tone + paraphrase + ask AI into the same keyboard. Ghostwriter has a longer 7-day trial; KeyAI offers a Lifetime option so you can stop renewing.
