EmoScan

EmoScan reads a message, email, review or social post of up to 2,000 characters and reports whether it sounds warm, cold, angry, sarcastic or tense, with an explanation. It is useful for checking a work email or a sensitive text before you send it.

Results appear in a few seconds as a shareable emotion card. Separate tools on the site cover anger detection, mood checks, review analysis, an AI text detector and a newer manipulation checker, and there is a mobile app.

The text checker is free and needs no sign-up. Some tools, such as the face scanner and lie detector, are entertainment features rather than reliable measurements.
