About AI Tools
Free, private tools for people who build with AI APIs.
What this site does
AI Tools helps developers, founders and teams estimate what AI API usage will cost. The AI API Cost Calculator turns token counts into per-request, monthly and yearly costs, the AI Token Counter shows how many tokens a prompt uses, and the pricing comparison lists per-token prices side by side.
Where the prices come from
Prices are collected by hand from each provider's public pricing documentation and shown in US dollars per one million tokens. The date of the last update is shown on the pricing page. Providers change prices often, so please confirm the current rate on the provider's own page before you commit to a budget.
Privacy by design
The calculators run in your browser. Text you paste into the token counter is never uploaded to our server. Read the privacy policy for details.
