Toolenox AI is an independent collection of 23 free calculators available in English and Italian. Our aim is to make everyday calculations understandable through clear inputs, worked examples and transparent limitations.
How are results calculated?
Our tools perform calculations locally in the visitor's browser with no account required. Each uses formulas and inputs chosen by the user. Calculator pages explain the arithmetic through examples and disclose relevant assumptions about rates, measurement units or calendar rules. Output accuracy depends on the information you provide.
How do we review and maintain the tools?
The project includes automated checks for numeric examples, invalid input, internal links and SEO release configuration. Changes are developed in separate Git branches, reviewed through pull requests and tested on preview deployments before publication. Automated checks reduce errors but do not constitute independent professional certification.
Which countries and units are supported?
The English version focuses on US users, including US dollars, US gallons and miles. The Italian version commonly uses euros and metric units. A separate UK VAT calculator covers British VAT rather than suggesting that the same rules apply to US sales tax. Real tax rates, exceptions and local regulations must be checked with authoritative sources.
Privacy, limitations and site information
Our calculators are informational and do not replace tax, financial or legal advice. Inputs are not submitted to a Toolenox AI calculation server. Netlify hosts the site and our contact forms are temporarily suspended. Read the privacy notice for an account of technical processing and information that is still being finalised.
