isthisaigenerated.app is an online tool platform focused on AI-generated content detection, with its core positioning being to provide a detection service that is "warning-only," covering three input types: images, text, and documents. The website emphasizes that detection results should be regarded as "signals rather than evidence," and that any important decision still requires human review.
Purpose
The website is used to check for warning signals of AI generation in images, text, and complete documents. It does not provide absolute determinations, but instead displays model, limitations, and background information to help users make more cautious judgments.
Main Capabilities
- Three detectors: respectively for images, text passages, and complete documents; users can choose the corresponding checker based on the input type.
- Results come with context: each result displays model information, limitation explanations, and source background, avoiding giving only a percentage without explanation.
- Platform-specific checkers: provides image detection tools for platforms such as Vinted, Marktplaats, 2dehands, Tinder, Catawiki, and Funda; users can paste a listing URL or upload photos to obtain an AI signal score for each photo.
- Detection API: supports Bearer authentication, synchronous checks, asynchronous tasks, and cache-first repeated requests, making it easy to integrate into existing workflows.
- Pre-publication review: combines claims, sources, warning signals, and human decisions, suitable for review processes before content publication.
How to Use
Users can start using it for free and receive 100 free tokens per week (UTC). Paid tokens can be retained persistently; one-time Stripe packages start at 5 euros, with no subscription or automatic overage charges. For platform-specific checkers, users can paste a listing URL or upload photos for detection. API integration requires Bearer authentication.
Applicable Scenarios
- Buyers on second-hand trading platforms (such as Vinted, Marktplaats, 2dehands) check whether product photos are AI-generated before paying.
- Users of dating apps (such as Tinder) check the AI signals of profile photos of matches.
- Bidders on auction platforms (such as Catawiki) check lot photos before bidding.
- AI signal scoring when viewing property photos on real estate platforms (such as Funda).
- Text and document review before content publication.
- Developers integrate detection capabilities into their own systems via API.
Limitations
The website clearly states that detection results are warning signals rather than proof, and each result comes with limitation explanations. All numbers come from holdout sets that the model was not trained on, and report sample size, false positive rate, and missed cases. The website emphasizes being "designed to be questioned," and human review remains part of every important decision. Details such as specific detection accuracy values, supported language ranges, and document formats are not yet provided in the materials.
