Are these tools really free?
Yes. There is no sign-up, no usage limit and no trial. They run in your browser, so they cost us nothing to serve.
Is my data sent anywhere?
No. Every tool runs client-side. The UTM builder keeps an optional history in your browser's local storage; nothing else is stored.
Do the tools use AI?
No. They are rule-based, so the same input always gives the same result. For AI-written work tailored to your site, thig's agents do that inside the product.
