Wordtune

What it is

Wordtune focuses on rewriting rather than generating from scratch. Highlight a sentence and it offers a stack of natural alternatives — more formal, more casual, shorter, or longer — powered by AI21 Labs' language models. Its Spices feature adds facts, examples, and counterarguments, making it a subtle but powerful editing companion.
