Unlike cloud-based platforms, Quaestio gives you complete ownership. No account required, no data mining, no privacy concerns. Everything lives on your device and you decide what to share.

Open Architecture
Use any OpenAI-compatible API: official services, local LLMs, or your own proxy. The app adapts to your infrastructure, not the other way around.

No ads, no paywalls for core features, no forced online services. Just a clean, efficient tool designed to help you learn and assess knowledge effectively.
