Winston AI review

Winston AI started as a text detector for schools and publishers, and its image detector adds a forensic view that many image-only tools lack. A scan reports whether an image looks AI-made or human-made and also reads EXIF, IPTC and C2PA information, while the analysis pipeline lists steps such as error level analysis, residual noise maps and an edge heat map. Images can be JPEG, JPG, PNG or WEBP up to 10 MB. The same account checks text for AI and plagiarism, which suits teachers and editors. The free tier is a 14-day trial with 2,000 credits rather than an ongoing plan, and the pricing page shows Essential at $18 a month on monthly billing alongside a 50 percent coupon price, so check the total at checkout. We compared documented features and published prices.
