About DozyTools AI

DozyTools AI is a small but growing collection of free browser-based AI calculators. The goal is to make AI usage easier to understand, whether you are budgeting API costs for an app or exploring the environmental impact of model inference.

The AI API Cost Calculator helps estimate token spend across popular providers, while the AI Energy & Carbon Footprint Calculator helps translate AI activity into electricity, CO2, water, and real-world equivalents.

More AI tools can be added here over time, but this new section already gives these calculators a dedicated home outside the broader `/tools/` collection.
