## Advacheck

Advacheck is an academic integrity toolkit built around two core engines: a plagiarism detector that compares submitted documents against reference collections and web sources, and an AI detector that estimates how much of a text was machine generated. The AI detector is trained to recognise output from a long list of large language models, including ChatGPT, Gemini, Llama and others, and the vendor states a false-positive rate below 0.5% — a figure that matters most to the students and researchers who would otherwise be wrongly accused.

The product line is split into tiers rather than one generic checker. Advacheck.Basic is the entry-level AI detection option, Advacheck.Expert extends the analysis, and Advacheck.Edu is packaged for educational institutions that need classroom-scale checking and reporting. Alongside those sits the standalone Plagiarism Detector, which supports similarity checks on both text and images — useful for publishers reviewing figures and graphics as well as manuscripts.

The company has been working on language models and text analysis since 1997 and now positions itself as a partner for the higher-education sector, with integrations such as its certified Moodle partnership. Pricing is handled through the sales team, so institutions typically request a quote rather than buy off a public price list. The broader pitch is that original, human-written content protects both academic credibility and search visibility.

**Pricing & Plans:** Contact for pricing. Advacheck does not publish a public price list; universities, publishers and teams request a quote or demo through the site's contact form to get plans for the AI Detector tiers (Basic, Expert, Edu) and the Plagiarism Detector.

- **AI content detection:** Flags text likely generated by ChatGPT, Gemini, Llama and other large language models, with the vendor claiming a false-positive rate under 0.5%.
- **Plagiarism detection:** Compares submissions against extensive reference sources and the web to surface unoriginal passages and improper citation.
- **Text and image similarity:** Goes beyond prose to check figures, graphics and other images for similarity, which suits publishers and research reviewers.
- **Tiered product line:** Advacheck.Basic, Advacheck.Expert, Advacheck.Edu and a standalone Plagiarism Detector let institutions pick the depth of analysis they need.
- **Education platform integration:** Certified Moodle partnership brings checking into a widely used learning management system, with reporting aimed at instructors and administrators.

**Strengths:** Covers both plagiarism and AI-generated text in one platform; Explicit text and image similarity checking, which many detectors lack; Long track record in language analysis dating back to 1997; Strong focus on education workflows, including a certified Moodle partnership

**Limitations:** No public pricing, so you must contact sales before you can evaluate cost; No free tier or instant self-serve signup is advertised; False-positive accuracy claims come from the vendor and are not independently published on the site

## Copyleaks

Copyleaks has focused on content integrity since 2015, starting with plagiarism detection and expanding into AI detection and governance as generative models spread. Its core AI Detector analyzes text across more than 30 languages and can identify output from leading models such as ChatGPT, Gemini, Claude and DeepSeek, while its Plagiarism Checker searches a database covering 60 trillion websites, 16,000+ open-access journals and millions of internal documents to catch copying, paraphrasing and character manipulation. A unified multi-modal layer adds detection for video, audio and images, aiming to replace fragmented single-purpose tools.

For organizations, Copyleaks goes beyond individual checks with a scalable API that plugs content analysis into existing workflows, LMS platforms and publishing pipelines. Its compliance and governance use cases map to academic integrity, generative AI governance, code governance, IP and copyright protection, and detection of unauthorized LLM usage. Reporting dashboards, integrations and role-based controls help teams act on results at scale.

Founded as a plagiarism tool, Copyleaks now serves both individuals and large institutions. Free web tools give students and writers quick access to the AI Detector and Plagiarism Checker, while paid enterprise plans provide higher volumes, richer reporting and dedicated support. The company reports 100+ countries, 500+ enterprise and education customers and tens of millions of monthly scans.
