What Winston AI Inc. does
Winston AI Inc. is a privately held software company headquartered in Montreal, Quebec, that operates a content integrity platform centered on AI-generated content detection. The flagship AI Content Detector applies natural language processing and deep learning to score text on a 0–100 human/AI scale, with a claimed 99.98% accuracy rate, sentence-level prediction mapping, weekly model retraining, and detection of outputs from ChatGPT, Google Gemini, Claude, LLAMA, and other large language models, as well as paraphrased and humanized bypass attempts. The platform is extended by an AI Image Detector for deepfakes and outputs from Midjourney, Stable Diffusion, DALL-E, Adobe Firefly, ChatGPT Image, and Nano Banana; an Advanced Plagiarism Checker; and an ancillary suite including Writing Feedback, Essay Grader, Fact Checker, Grammar Checker, HUMN-1 Website Certification, Text Compare, Readability Checker, and Citation Generator.
The technology stack is exposed through three REST APIs (AI Content Detection, AI Image Detection, and Plagiarism Checker) with a 99.9% uptime SLA, and through integrations with Chrome Web Store, WordPress, Zapier, Google Classroom, and the ChatGPT GPT Store. Detection supports 14+ languages, OCR handles scanned and handwritten text, and the company states GDPR, CCPA, and LGPD compliance with explicit no-training-on-user-content policies.
The business model is product-led and freemium, with a 14-day free trial, monthly subscriptions paid via major card networks in nine currencies, paid API access for developers and enterprises, and a 40%-commission ambassador and affiliate program on Rewardful. Go-to-market is primarily self-serve direct to a claimed 10M+ users across three primary verticals — education (academic integrity), SEO and publishers (Google ranking protection), and writers (content originality) — supplemented by earned media coverage in major outlets and a multi-marketplace distribution footprint. The company discloses no funding rounds, headcount, revenue figures, or ownership structure beyond its Quebec corporate registration.
