When I started CzechFabric, I wanted to make real-world data more usable for AI, not just for experiments, but for production. TONE was born out of that frustration: JSON was too heavy, YAML too inconsistent. Now it’s a simple, open format that helps AI understand data more quickly and cost-effectively. Built in Prague 🇨🇿, open to everyone. Would love to hear your feedback!

This is amazing. Can you show an exact use case?

I see the mention of public-data APIs; what kind of city or open innovation data are you providing first?

I like the concept. Frankly, as an American with my company's headquarters in Praha 1 I had to look at this.
