40 free tools. One question each. Answered in under a minute.
Checkers, calculators, builders and decoders for tradespeople. No signup. No paywall. Open the one you need, get an answer, get on with your day.
Every tool here is built around a single question a tradesperson actually asks - 'is my pay legal?', 'does this need regs?', 'what does this SARS letter mean?'. They all cite the rule or law they're based on. None of them need you to create an account.
