Winston AI
Document, image, and OCR detection in one reporting-focused tool.
Winston AI markets itself to professionals who need defensible reports. Beyond text it can scan uploaded PDFs, Word files, and even images for AI generation, a capability few detectors matched in 2026. Its free tier covers 2,000 words, with paid plans from $12 a month that add batch uploads and branded PDF exports. Reviewers consistently rank it as the overall most accurate detector on unedited AI output, though its headline 99.98% claim has not been independently verified. For publishing and journalism workflows where image authenticity also matters, the combined text-plus-image scope is the differentiator.
