Pick ChatGPT if everyone who wants a hosted general assistant — writing, Q&A, light research, images. Pick QuillBot if students and marketers who want a controlled rewrite of an existing draft. Skip ChatGPT if teams that cannot send prompts to OpenAI, or developers who need a repo-aware IDE (Cursor) or a local runtime (Ollama). Skip QuillBot if people who need an inline overlay in every text box (Grammarly) or a
signed-out paraphraser
