AI Token Estimator
Estimate token usage and API costs across major AI models
About
AI Token Estimator calculates token counts and real‑time API costs for OpenAI, Anthropic, Gemini, and DeepSeek. It also shows each model’s context window limits, helping you understand how much text can be processed. Unlike generic calculators, it pulls up‑to‑date pricing and supports multiple providers in one interface. Use it to budget your AI usage accurately.
The case
Who it is for
Engineers and product managers who need accurate token cost estimates for AI model usage.
What is broken today
Before this tool, estimating token usage and API costs required manual calculations or unreliable third‑party tools, making budgeting for AI workloads difficult.
What it does about it
The estimator parses your prompt, counts tokens, and calculates cost based on real‑time pricing from OpenAI, Anthropic, Gemini, and DeepSeek, also showing context window limits.
Why not the obvious alternative
Unlike generic calculators, it supports multiple providers, provides up‑to‑date pricing, includes context window limits, and gives instant cost estimates.
