Micro-SaaS with $3,552 ARR and 71 customers. The target audience is Universities. In October 2022, I got approached by two friends living in Australia about an opportunity of AI detection in the educational sector for detecting GPT-3 usage (as ChatGPT wasn't launched at that time). Within weeks we built a custom AI model able to accurately predict AI usage with 70%, and every week it became more accurate. At the latest training cycle the model was 99.7% accurate, one of the most accurate AI detectors in the world. But more importantly the False Positive rate is 0.03%, so only 0.03% of the times the text was identified as AI written while in fact human written. <br>✅ $3,552 in ARR<br>✅ 71 customers<br>✅ Business model: SaaS<br>✅ Built with Django, React, SQLite<br>
