What they are

QuillBot

QuillBot is an AI writing suite built around a paraphrasing tool, with a summarizer, grammar checker, citation generator, and plagiarism checker layered around it. 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.

DeepSeek

DeepSeek is a large language model chatbot developed by a Chinese AI lab, available free via web, app, and API. Creators, developers, and researchers use it for writing, coding, summarization, and reasoning tasks. Its R1 reasoning model performs competitively with much more expensive alternatives, making it a credible option for budget-conscious creators. Data is processed on servers based in China, which is a real consideration for sensitive content.
