Spotted a typo in a letter, or a paragraph that sounds too stiff for a client email? Select the passage in our PDF editor and let the assistant proofread it, rephrase it, shorten it, or change its tone to formal, simple or concise. The new text replaces the selected block, and you keep editing as usual.
It's ideal for polishing a cover letter, clarifying instructions for parents, or making a report easier to read for people working in their second language. You decide whether to keep each suggestion, so the final wording is always yours. The assistant only receives the passage you select, not the rest of your document. As with any AI output, read the new version before keeping it, especially for names, figures and technical terms.
Try it with the assistant's free trial on a verified account, then continue on the AI or Pro plan or with a 24-hour pass; rewrites are counted in AI pages. Your text is never used to train any model, and we only use paid AI APIs. The classic editor itself stays free to use.
