Frequently Asked Questions
Are the tools free to use?
Yes. Every tool is free, with no account, no paywall, and no usage limits beyond the per-tool input size shown on each tool's page.
Do I need to create an account?
No. There are no accounts, sign-ups, or logins anywhere on the site — none of the tools need one to work.
Is my data sent to a server?
No. Every tool runs entirely in your browser; input is processed locally and never transmitted anywhere. Tools that handle particularly sensitive input, such as passwords, display a visible notice confirming this on the tool page itself.
Why are there ads?
A small amount of unobtrusive advertising helps cover hosting costs so every tool can stay free with no paywall. Ads are not permitted to track you across other sites — see the Privacy Policy for details.
How often are new tools added?
New tools are added iteratively, in small batches, and only once each one is fully finished — widget, content, and tests — rather than published half-built to hit a schedule.
