How to Translate Substack From Vietnamese to Italian (Step-by-Step)
Vietnamese-language content on Substack is rich and worth reading. If Italian is your stronger reading language, the usual friction applies: copy the text into a translator and lose the layout, or read slower than you would like.
This guide shows a third option — translate the Vietnamese newsletter in place, directly into Italian, with bilingual translation. The Vietnamese stays visible and the Italian meaning appears right beside it, so you can read the meaning quickly and still check the original for any word, name, or phrase.
Demo note: the screenshots below are built in a real Substack layout to show exactly how BothLang displays a bilingual page — the Vietnamese paragraph on top and the translated Italian directly beneath, with a hand-drawn arrow pointing at the translation.The workflow is identical on any newsletter because BothLang works on whatever page you are viewing.

- BothLang installed in Chrome, Edge, or Firefox — see the download page.
- The extension pinned to your toolbar.
