What is useful to send
- A tool that gave a wrong answer, with the input that caused it.
- A tool that is missing, and the job you were trying to do.
- A bug on a specific phone or browser, with the browser name and version.
Please do not paste private data. If you are reporting a formatting bug, a shortened version of the input is enough.
What to expect
