Private by default
Calculators, generators and the token counter run on your device. Nothing you type is uploaded or stored.
Numbers you can check
Every tool page shows its formula or rules, worked examples, and its limits. Prices are sourced and dated.
Shareable results
Calculator inputs live in the page address — copy the link to send a scenario to a co-founder or investor.
