## 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.

- **AI content detection:** Identifies AI-generated text across 30+ languages and leading LLMs, with reported accuracy above 99% on internal English test sets.
- **Plagiarism checking:** Searches 60 trillion websites, 16,000+ open-access journals and internal repositories to catch paraphrasing and hidden copying.
- **Multi-modal detection:** Extends detection to AI-generated video, audio and images so teams can verify content beyond text alone.
- **API and integrations:** A scalable API and workflow integrations automate content analysis inside LMS platforms, publishing tools and enterprise systems.
- **Governance and compliance:** Supports academic integrity, GenAI governance, code governance and IP protection programs with reporting and controls.

**Strengths:** Combines AI detection and plagiarism checking in one platform; Broad language coverage and a very large comparison database; Scalable API and workflow integrations for enterprises; Free tools available for individuals alongside paid plans

**Limitations:** Pricing is quote-based and aimed mainly at organizations; AI-detection results can produce false positives on human writing; Full feature set requires an enterprise contract

## Proof&Trust

Proof&Trust targets the supply-chain obligation created by NIS2 Article 21(2)(d), which makes the security posture of direct suppliers the responsibility of the buying organisation. Instead of chasing annual questionnaires across document stores, the platform ingests contracts, vendor masters and document repositories, then automatically validates the authenticity, validity and scope of certificates, attestations, SBOMs, penetration-test reports and policies.

Each artifact receives an evidence-grade score based on completeness, recency, source trust and control coverage. These scores roll up into a vendor risk index that is recalculated continuously rather than frozen at an annual snapshot, and vendors are auto-classified into tiers — critical/high, important/medium and baseline/low — according to dependency, concentration and evidence quality. Tier changes are timestamped, traceable to the underlying evidence, and exportable as audit-ready proof, so a new CVE or expired certificate can move a vendor up the risk ladder within minutes.

The vendor says a sample portfolio can be scored in under 30 minutes with no integration and no credit card, in an EU-hosted environment with data residency and encryption in transit and at rest. Reporting is mapped across all ten NIS2 Article 21(2) measures, and the platform also supports Article 23 incident-notification drafting with 24-hour early-warning timing. The offering is aimed at compliance, security and procurement teams in regulated sectors such as banking, energy, healthcare, telecom and the public sector.

**Pricing & Plans:** Published annual tiers in euros (excluding VAT). Basic: €1,999/year for up to 20 vendor assessments. Professional: €4,900/year for up to 100. Enterprise: €9,900+/year for up to 300, with custom branding, a read-only auditor account, API export and SLA. Larger portfolios and private/on-prem deployments are quoted individually. A free sample assessment and a free trial are offered.

- **Evidence ingestion and validation:** Connects contracts, vendor masters and document stores, then verifies the authenticity, validity and scope of certificates, attestations, SBOMs, pen-test reports and policies.
- **Artifact and vendor scoring:** Scores each artifact on completeness, recency, source trust and control coverage, then rolls the results into a continuously recalculated vendor risk index.
- **Continuous NIS2 tiering:** Auto-classifies vendors into critical, important and baseline tiers by dependency, concentration and evidence quality, re-tiering the moment evidence changes.
- **Audit-ready reporting:** Produces cited, exportable evidence trails mapped to all ten NIS2 Article 21(2) measures, plus Article 23 incident-notification drafting with 24-hour early-warning timing.
- **No-integration onboarding:** Drop in a sample of supplier evidence and receive a scored, tiered portfolio in under 30 minutes, with NDA available and EU-hosted data residency.

**Strengths:** Published euro pricing makes budgeting straightforward, unlike many compliance platforms; Continuous scoring and re-tiering beats an annual questionnaire snapshot when risk changes mid-year; No integration is required to get a first scored portfolio, and a free sample assessment lowers the trial risk; EU-hosted with data residency and explicit mapping to all ten NIS2 Article 21(2) measures

**Limitations:** Focused squarely on NIS2, so organisations outside its scope get less out of the tiering model; Assessment caps per tier (20/100/300) mean very large vendor estates need a custom quote; It is a newer platform, so it lacks the long public track record of established GRC suites
