Airno
Airno analyzes text and images to estimate whether they may have been generated by AI, returning a confidence score and a breakdown by detector.
What Airno is
Airno analyzes text and images to estimate whether they may have been generated by AI, returning a confidence score and a breakdown by detector. Its web interface accepts up to 50,000 characters and highlights suspicious spans. Airno describes seven parallel detectors, including statistical analysis, RoBERTa and DeBERTa classifiers, and linguistic pattern rules. It says text checks cover systems such as ChatGPT, Claude, Gemini, LLaMA, and Mistral, while image checks cover DALL-E, Midjourney, and Stable Diffusion. Image analysis includes CNN artifact analysis and frequency-domain inspection. Airno reports approximately 85–92% accuracy on unedited AI text samples of at least 200 words and an 8–15% false positive rate. It recommends at least 50 words for meaningful analysis and notes that very short text is less reliable. The Free plan costs nothing and allows 100 API requests per calendar month, resetting on the first day of each month. Pro costs $19 a month, with unlimited API requests, priority support, and a 99.9% monthly uptime SLA. Airno says submissions are discarded after analysis, though anonymous aggregate counts may be retained.
Good
- Analyzes both text and images
- Web interface accepts up to 50,000 characters
- Free plan includes 100 API requests monthly
- Submitted text and images are discarded after analysis
Watch out
- Free plan is limited to 100 API requests monthly
- Airno reports an 8–15% false positive rate
- Very short text results are less reliable
Who it suits
Airno may suit people who want to check text or images for possible AI generation, with web access or a REST API. Its short-text caveat and reported false positive rate matter for anyone relying on a result.
Verdict
Airno provides text and image detection with a detector breakdown and API access. Treat its estimates as uncertain, especially for short text, given its stated accuracy and false positive limitations.
