Winston

Powerful AI content detection solution for education and publishing

Winston AI is the industry-leading AI content detection tool that helps check content generated with ChatGPT, GPT-4, Bard and many more Large Language Models (LLMs).

It claims to be the only AI detector with a 99.6% accuracy rate, as it constantly keeps its software up to date with every notable LLM update.

As such, Winston is made for writers, web publishers and educators — making sure they “deal” or produce original content. Google and search engines may penalize unoriginal work, and educators don’t want to reward students using tools like ChatGPT for their homework.

Winston AI also offers a plagiarism checker, making sure the original content/idea creator is given credit for their work.

The tool can handle text input, as well as .docx, .png, and .jpg files — using Optical Character Recognition (OCR) tech to extract text from scanned documents or pictures. It can be tried out for free.
