AI Essay Checker vs AIssistify

AI Essay Checker (EssayCheck) is an online writing tool that scans essays for AI-generated text, grammar errors, and plagiarism in one editor. Paste or type your essay, then run AI detection, grammar checking, or plagiarism scanning separately or together. The AI detector estimates how much of your text may have been written by tools like ChatGPT, Gemini, Claude, or Copilot.

The grammar checker flags spelling mistakes and grammatical issues with real-time suggestions. The plagiarism scanner identifies duplicated or AI-copied content so you can edit before submitting. EssayCheck also includes an Essay Grader for automated scoring and feedback.

The platform supports English plus French, German, Spanish, Italian, Portuguese, Dutch, and Russian. Free accounts include monthly word limits on AI detection and plagiarism checks, with paid Basic and Pro plans for higher volumes.
