Winston AI is an AI content detector and plagiarism checker built for education, SEO, and writing. You paste text or upload Word documents and image files, and OCR extracts text from scans and even handwriting. Results arrive in seconds on a 0 to 100 scale, with an AI Prediction Map that colors passages by how likely they are machine-written. It also detects AI-generated images and deepfakes, checks for plagiarism, and produces shareable PDF reports. Detection works in 14 languages, and the company reports 99.87% accuracy for Winston 5.0.
Teachers, professors, and academic institutions use it to protect integrity in student work. SEO teams and publishers scan articles before publishing to catch low-quality or unoriginal content, and freelance writers check their own human score before delivery. Agencies can invite team members on higher plans, and developers can connect through the API. More than 10 million users are cited, and the service states that it is GDPR compliant and never uses submitted content to improve its models.
An instructor can run a stack of essays through the detector and share a report with a student or an academic integrity office. A content manager can scan freelancer submissions, then activate plagiarism checking on any that look suspicious. A publisher can verify an image before running it, and a site owner can apply for HUMN-1 website certification. New users get a 14 day trial with 2,000 credits. Paid plans are $18 per month for Essential, $29 for Advanced, and $49 for Elite, with lower rates on annual billing.
