What to include
- A mistake in an essay or answer: the page address, what you think is wrong and, if you can, a source. Corrections are made openly.
- A wrong result from a tool: the page address, the values you entered, the result you got and the result you expected. A screenshot helps.
- A topic or tool idea: what you wanted to know or do, and where you looked first. Suggestions directly shape what we write and build next.
- Privacy questions: our privacy policy explains what is and isn’t collected.
Please don’t send personal financial documents or files you want processed. Our tools work in your browser precisely so that you never have to share them.
