Contact Us
Bug reports, ideas and questions are welcome.
We read every message about errors, feature ideas and questions about the site.
What to include
- For a bug: the tool name, your browser and version, and the smallest input that reproduces it. Please remove anything private first; we cannot see what you typed into a tool because it never leaves your browser.
- For a new tool: what you would paste in, what you expect to get out, and a link to the specification if there is one.
- For privacy questions: see the Privacy Policy.
What we cannot do
We cannot recover or look up anything you entered, because the tools run locally and we never receive it. We also cannot offer support for your own applications or review private code.
This site has no contact form or backend, so please use the email address above.
