No, this free tool does not use a built-in plagiarism checker. However we do have a plagiarism checker (coming soon) inside the full RightBlogger AI content creation platform, which serves the purpose of illustrating that AI content doesn't constitute plagiarism—as it doesn't "copy" from any specific sources. Rather, AI algorithms are learning from a vast database of almost everything on the Internet and synthesizing, paraphrasing, rewording and reformulating totally unique answers to your queries every time you generate an article. Inside RightBlogger, we have dedicated tools for everything from a text summarizer to an expander & everything in between that'll help you create more content, faster.
