ContentDetector.org vs TrustOriginality.ai

ContentDetector.org is a free tool that estimates whether text was AI-written and reports a percentage split between AI-written and human-written content. Users can paste text, upload a file, or submit a URL for a report with a score, section highlights, and review guidance. The site says the detector evaluates token-pattern predictability, semantic repetition, formatting regularity, and local stretches of uniform phrasing, including patterns associated with GPT-5, Gemini, Claude, and other large models. It also offers a converter that rewrites AI-generated text to improve tone, flow, clarity, and sentence variety; the converter page shows a 1000-character input counter. Other listed options include API access and bulk checks of folders or URL lists. Platforms include web, extension, iOS, macOS, and Windows. The site says inputs are not used to train models and describes retention controls; its FAQ says inputs are removed when the tab is closed, while the converter page says submitted content is processed instantly and not stored. It warns results can be wrong, especially for very short or heavily edited text, and recommends human review.

TrustOriginality.ai analyzes text, images, audio and video for AI-generated or manipulated content. An analysis can provide an explainable Trust Score and findings for human review, along with a signed PDF report, QR verification and a public verification link for documenting evidence. The service lists web, Android, iOS and API access. Integration options include a REST API, Python and JavaScript SDK references, and publish-gate plugins for WordPress and Drupal; Shopify is listed as beta. The feature page lists AES-256 and TLS 1.3 encryption, access controls and authentication protocols. The company says the product supports EU AI Act Article 50 due-diligence workflows, but does not provide legal certification. Its Trust Center says SOC 2 Type I and ISO/IEC 27001 are not claimed, and enterprise SSO is under evaluation. The company describes its audience as European enterprise, compliance and media buyers, with workflows for public sector, finance, education, technology and legal teams. The free plan includes one text analysis per month. Paid plans start at €4.99/mo, and some workflows remain in beta and may change.
