- Statistical AI-text classifier (perplexity/burstiness-family approach comparable to GPTZero) built as separate, purpose-built detection engines per content modality rather than one unified multimodal model; as of August 11, 2026 those engines cover text, images, and (new) video, evaluating visual frames, temporal patterns, compression signals, and artifacts associated with synthetic media across MP4, MOV, AVI, MKV, and WEBM.

- Free-to-use, Iceland-based AI content detector site (founded 2023) offering dedicated tools for text, image, and, as of the August 11, 2026 launch, video content.
- distinctFrom
- Unlike GPTZero (a separate company it is frequently confused with, launched about 15 days earlier in 2023) or AI or Not (a single classifier spanning four modalities from one company, Optic), ZeroGPT ships separate, dedicated detection engines per modality and only added video coverage in August 2026, three years after its text-only launch.
- notes
- Quote attributed to Rawad Baroud, CEO and co-founder. ZeroGPT is an unfunded, Iceland-based company founded in 2023; vendor claims accuracy over 98%, but independent 2026 reviews (fast.io, aicheckr.io) report real-world accuracy in roughly the 60-85% range with false-positive rates up to ~33% depending on content type; not independently reverified here. Not previously tracked in this catalogue despite being a long-established GPTZero rival; the new video detector (Aug 11, 2026, within this lens's window) is the trigger for adding it now that it spans all three major content modalities.
