If you want to display footnotes without any numbers, you can do so by changing the footnote counter. This means you can make footnotes appear without any numbering at all.
To achieve this, you can use the following command:
\renewcommand{\thefootnote}{}
\documentclass{article}
\begin{document}
\renewcommand{\thefootnote}{}
In this text, footnotes\footnote{This is a footnote.} appear at the end\footnote{End.} \newpage
The page break is just here to show the effect on footnotes.
\end{document}
In this example, footnotes are displayed without any numbers, as we've redefined the command responsible for numbering footnotes to be empty. So when you add footnotes in the text, they'll appear without any numbers. The \newpage command is just there to illustrate the footnotes' placement across pages.
