Toolbox : AI Tools

The AI / news Toolbox brings together free tools for choosing, costing, and understanding artificial intelligence: estimate the cost of an API, compare models and subscriptions, track prices, count tokens, size a machine for local AI, measure energy consumption, or check your obligations under the AI Act. Choose a tool below.

These tools run directly in your browser, with no registration required: the texts and values you enter are not sent to any AI. Model prices come from OpenRouter’s public rates, updated daily; each page details the calculation principles and limitations of its estimates.
