@mejo- @max-nextcloud @julien-nc not fully sure if this is a Text issue or Assistant issue, but since Assistant just gives over the plaintext, I assume it is a Text app issue?

Should be text, we need to detect or always assume markdown like we do for smartpicker results:

text/src/components/Suggestion/LinkPicker/suggestions.js

Line 91 in 1d2f4cc

const isMarkdown = hasMarkdownSyntax(link) && isValidMarkdown(link)
