AI Detector API FAQs
The Lynote sandbox gives you 500 free trial credits so you can test the Detect endpoint with real content before investing in a paid plan. You need a card to activate the trial, but it will not charge you unless you upgrade.
The results of AI detection may vary depending on the text length and how much it has been edited after generation. Less-edited and longer passages generally give the detector more data to work with. You can treat the score as a useful signal for reviewing the content rather than a final decision on its own.
The Lynote AI detection system is built to identify patterns associated with Cloud Gemini, ChatGPT, DeepSeek, and other popular AI models.
A browser-based detector helps a person check the text manually. An API is useful when you want to integrate the AI detection feature within your own application. By using an API, your product can detect AI text for analysis, and you can display that to your user.
The AI detector API can detect short passages. However, shorter text does not give enough information to the detector. Therefore, the confidence score can be lower than it would be for a long paragraph. In some AI detectors, you would see a prompt saying that you need to add at least 100 words to detect text with full accuracy. This length may vary for each AI detector.
A bearer token is used in every request in the Authorization header. We recommend keeping your APIs on the server side for security purposes rather than exposing them in your frontend or browser code.
