Wordtune

Wordtune is an AI-powered writing companion focused on rewriting and refining existing text at the sentence level. It suggests multiple paraphrases to improve clarity, tone, and length, and can adjust formality. Its 'Spices' feature can add examples or counterarguments. Available as a browser extension and standalone editor, it uses a freemium model.

It's perfect for professionals, students, and non-native speakers who want to polish their phrasing in real-time. It scores well for its exceptional sentence-level rewriting capability and seamless integration into writing workflows, complementing rather than replacing the writer.
