Why use these AI Tools?
Optimization First
Understanding token usage is the first step to reducing API costs and latency. Our calculators use widely accepted standards.
Debug Faster
Don't let broken JSON or bad chunking ruin your RAG pipeline. Visualize your data flow before it hits the model.
Privacy Focused
All calculations happen client-side. We never send your prompts or data to our servers.
