About
Who’s behind Synthin.
Synthin AI is founder-led: when you write to us, you reach the person who built the measurement engine — and every report is personally overseen from measurement to fix list.
David Leonard Nagy
Founder · AI engineer
I work in machine learning with a focus on natural language processing— the field that studies how AI systems read, write, and answer. I’ve done research in NLP, and I’ve represented Hungary at the International Olympiad in Artificial Intelligence (IOAI), bringing home a silver and a bronze medal from its first two editions.
I also build and ship real software: years of Python, JavaScript and TypeScript, APIs, Docker, and cloud deployments. I’m the author of EcoTorch, an open-source Python library on GitHub and PyPI that tracks the power consumption of machine-learning models.
Synthin started with an experiment: I built an engine that asks AI assistants real buyer questions and logs every answer, then measured 11 real Budapest businesses across 88 ChatGPT answers. Three of them — established, well-reviewed businesses — were never mentioned. Not once. Their owners had no idea. That gap, between what AI tells your customers and what you can see, is what Synthin closes.
