TokenCALC helps developers, founders, and finance teams estimate LLM token usage and API cost before they ship prompts to production.
What we build
We run a privacy first token and cost calculator in the browser. Your prompt text stays on your device for counting. We also publish guides, model pricing notes, and comparison pages so you can plan budgets with clearer assumptions.
Our approach
- Exact token counts when a local encoding is available.
- Transparent Approximate labels when a provider encoding is not available in the browser.
- Catalog pricing with last verified dates so estimates stay auditable.
- Evergreen guides that explain tokens, context windows, caching, and pricing math in plain language.
