About AI Rewriter
This AI paraphrasing tool helps when you know what you want to say but not quite how: an email that sounds too blunt, a product description that runs long, a cover letter that needs a more formal voice, or instructions your readers find hard to follow. Paste your own text, pick how it should change and get a new version back. To pull the main points out of a whole PDF or Word file instead, use the AI Summarizer.
Rewrite to be offers six directions. Polished fixes flow and word choice, Shorter trims without dropping the point, Longer adds detail, More formal and More casual shift the tone, and Simpler uses plainer words and shorter sentences. Leave Language on Detect automatically, or choose the language you want the result in. Read the new version before you send it; the AI can change a nuance or a fact you meant to keep.
