What is Advacheck?

AI and plagiarism detection with few false positives.

Who is Advacheck best for?

Advacheck is best for universities and publishers that need to check English texts for AI writing and plagiarism.

  • Universities and colleges

    Advacheck.Edu adds teacher and student workspaces, course and task setup and admin statistics, and Advacheck is a certified Moodle partner.

  • Publishers and research bodies

    Advacheck.Expert gives reviewers their own workspaces, a custom document collection and bulk uploads to check text and image similarity and AI-written passages.

  • Spotting AI-written English text

    The AI Detector marks which sentences were likely written by ChatGPT, Claude, Gemini or other models, and the maker claims under 0.5% false positives.

  • Organisations with strict data rules

    Standalone and Protected versions run on the customer's own server, and the Protected one is cut off from outside networks entirely.

How much does Advacheck cost?

Advacheck does not publish prices: organisations buy it through a demo request or its sales team, and the maker offers a 14-day free trial that comes with a demo account.

Advacheck shows no prices: every cloud product (AI Detector, Basic, Expert and Edu) and the on-premise Standalone and Protected versions lead to Request Demo or Talk to sales.
