ToneAI

ToneAI is a free AI tone checker and text tone changer: paste an email, social post, support reply or marketing copy, pick a tone (warmer, friendlier, more professional, more formal, and more), and get it rewritten in seconds without changing the meaning. Built-in templates cover common cases like a weekly status update, a follow-up email or a reply to an angry customer.

Five rewrites are free with no signup; a 7-day Premium trial (no card required) unlocks multiple rewrite variants, all 8 tones and every template.
