Revisy.ai Plagiarism checker is a content detector tool. A web-based plagiarism checker for essays and papers that charges per check, based on word count, with no membership. Reports show similarity percentage, matching sources, and highlighted passages linked to source details.
Revisy.ai Plagiarism checker is a web-based tool that compares an essay, paper or draft against outside sources and returns a similarity report. Text can be pasted directly or uploaded as a PDF, DOC or DOCX file up to 10 MB, and the page states that document content is never included in analytics. No membership is involved: each check is paid for individually, with the price set by the document's word count, and payment is completed before analysis begins. The report is built around context rather than a single number. It shows an overall similarity percentage next to the total word count, then breaks the result down by number of sources, matched words, matching passages and per-source similarity. Matches are sorted into direct matches, which are exact language, and similar matches, which are related wording. In the report view, the document sits on the left and source details on the right, so selecting a highlighted passage brings up the source it was matched to. After the check runs, an overview is available first, and the full report with passages and source context is unlocked through the purchase. The audience is mainly students and academic writers who want to review essays, research papers, literature reviews and thesis chapters before submitting. The site is explicit that the report should guide revision and not replace careful citation and editing. A set of linked guides covers what a plagiarism checker is, how detection works, how to read a similarity score and how to avoid plagiarism. Among alternatives, the tool sits closer to one-off, pay-as-you-go checkers than to subscription suites or institutional systems. That suits someone who needs a single check before a deadline and does not want a recurring plan. The FAQ headings raise AI-writing detection as a question, but the homepage text does not state what the answer is, so buyers who need that capability should confirm it on the site before relying on it.
