ZeroTrue checks text, images, audio, video, and code for signs that content may be AI-generated, through a web checker and API. Results give an overall probability and supporting details, such as highlighted regions or timestamps, for a person to assess; they are not proof of authorship or intent. The API uses one request pattern across the listed media types, with batch processing and asynchronous webhooks among its capabilities. Python, TypeScript, and Go SDKs are listed, along with Android and iOS apps, a Telegram bot and Mini App, MCP connectivity, and an agent skill. Detection confidence can be reduced by short samples, editing, compression, translation, re-recording, mixed human and AI content, or new generators. The free web image checker accepts JPG and PNG files up to 10 MB. The free plan is free and includes 100 detections per month, API access, a web dashboard, and community support. Enterprise features include on-premise deployment, SSO and SAML, a custom SLA, and a dedicated account manager. ZeroTrue advises human review rather than relying on detector results alone for high-impact decisions.
