Paste up to 100 words and get an indicative, paragraph-by-paragraph estimate of how likely your writing sounds AI-generated, with flagged sentences and honest notes. It's an estimate, never proof.
The same engine that powers the AI Detector inside the dashboard.
Copy a paragraph or two from your draft. The free check works best on 30 to 100 words.
Each paragraph is scored 0–100 and labelled Human-sounding, Mixed, or Likely AI-generated, with flagged sentences and reasons.
Use the result as a signal to rewrite anything that sounds formulaic. Detection is indicative, never proof.
The honest way to use an AI detector is on your own work, before you submit.
AI detection is contested and imperfect. A score is a signal about how a text sounds, not a fact about how it was written. That is why this tool always labels its output as an estimate, and why we recommend it for reviewing your own writing rather than judging anyone else's.
The paragraphs that score high are usually the ones that read generically: sweeping claims, tidy transitions, and sentences that could come from any essay on the topic. Rewriting those in your own voice is good practice regardless of the score.
The free check is a taste of the full AI Detector in the RefineMyDraft dashboard, which handles whole documents and uploaded .docx files. It sits alongside essay review with every change explained, the personal statement generator, free citations and word-count reshaping.
