What is AI Token Cost Estimator?
AI Token Cost Estimator is an in-browser tool that helps developers, product managers, and ML teams forecast API spend across major LLM providers before writing a single line of integration code. Paste a sample prompt and an optional expected response, set your daily request volume, and the estimator projects per-request, monthly, and yearly costs for 13 models from OpenAI, Anthropic, Google, Meta, and Mistral. A sortable, filterable comparison table highlights the cheapest option at your volume, and one click exports the whole table to CSV for budget spreadsheets. Everything runs client-side - your prompt text never leaves the browser.
Key Benefits
