What Winston AI does
Winston AI is a Montreal-based, privately-held software company founded in 2022 that builds AI-generated content detection tooling, primarily targeting educators, SEO professionals and digital publishers, and individual writers. Its core product is a text-classification engine that uses natural language processing, deep learning, and statistical signals (perplexity and burstiness) to assign a probability score indicating whether a passage was written by a human or by major LLMs such as ChatGPT, Claude, Gemini, and Llama; the platform claims 99.98% accuracy on its advanced scan and 92-96% accuracy in third-party testing. The product suite has been extended in 2026 to include a forensic AI image detector for deepfake identification and generative-tool attribution, plus plagiarism checking, writing feedback, essay grading, grammar checking, fact checking, citation generation, and OCR for scanned documents. Distribution is global and multi-lingual (14 languages) via a freemium web app, a Chrome extension, WordPress and Google Classroom integrations, a Zapier app, and presence in the ChatGPT GPT Store.
The business model is product-led growth on top of a freemium-to-subscription funnel: a free tier with a 2,000-word monthly cap, a $18/month professional plan, and API access for enterprise and developer integration. A 40% commission affiliate and ambassador program (operated through Rewardful) drives organic acquisition, while a "Contact Sales" path signals an emerging enterprise motion for journalism, legal, and large education deployments. The company reports being trusted by 10M+ users and is GDPR/CCPA compliant with a stated policy that submitted content is not used to train its models. Funding, ownership, and revenue figures are not disclosed in the available sources, and the headcount is reported at 1-10.
