QuillBot

It is popular with students for reworking and rephrasing text at a low price. It refines existing content rather than generating from scratch, and creative rewrite modes can trigger AI detectors.
Writesonic
Writesonic is an AI writing platform that generates blog posts, product descriptions, ads, and social copy using large language models. It targets marketers, agencies, and solo creators who need to produce a high volume of written content quickly. The platform includes a chatbot (Chatsonic), an AI article writer, and brand voice controls. Output quality is solid for drafts but still needs human editing before publication.
