Free academic writing tools for students

All GradeQuill tools are completely free to use with no word-count limits, no sign-up required, and no hidden charges.

Why check before you submit?

Running your essay or dissertation through a plagiarism checker before submission gives you confidence that your referencing is accurate and your paraphrasing is sufficiently original. Many universities use Turnitin or similar tools, and identifying similarity issues early gives you time to correct them without affecting your grade.

AI detection for academic writing

AI-generated content is increasingly flagged by UK universities. Our AI detection report service helps you understand how your writing is perceived by detection tools. Contact us on WhatsApp or email to request a manual AI detection report for your document before you submit.
