CheckforAi

CheckforAi was a free nonprofit project built to help people detect AI-generated text in essays and emails. It combined OpenAI's Roberta-base model for GPT detection with proprietary models developed by the team, offering a reliable way to spot machine-written content at a time when AI writing was rapidly spreading. The service has since been sunset as the team shifts focus to new projects, but it marked an important early effort in making AI detection accessible and free for everyone.
