FAQ
Can you match my website's design?
Yes — send your URL or a screenshot and the tool will match your colors and fonts exactly.
Does it need monthly payments/API keys?
No. Tools run in the browser with no server or API costs unless your tool needs live external data (we'll discuss first).
Can it work on WordPress?
Yes — delivered as an embeddable snippet that works in any page builder or plain HTML.
What if I need changes later?
Revisions are included; bigger changes are cheap add-ons. You own all code either way.
