How to use Winston AI
- The official website offers a free trial without a credit card.
- It is recommended to first run a few known source texts (one pure human-written, one pure AI-written, and one human-AI hybrid) to get a feel for how these scores perform in your scenario before deciding whether to make a purchase.
- When reviewing the results, focus on the Prediction Map first and the total score second: knowing which paragraphs triggered the alerts is the only way to figure out what needs to be revised.
- Image detection works well in conjunction with text detection, but there is still error margin in synthetic image judgments—do not rely on a single conclusion for critical scenarios.
- When using detection results for academic or personnel decisions, be sure to retain manual review and appeal processes—no matter how high the accuracy rate is, the output is essentially a probability.
- Pricing, scan limits, language coverage, and accuracy metrics are subject to adjustment.
- double-check the official website’s instructions before official use.
