Unfortunately, I can’t download Logseq and use this app on Windows and even if exists a way to download on Windows and I don’t know about it yet, it is a thing that needs to better, because is not easy to download.
You can download it here: https://github.com/logseq/logseq/releases
Search for: logseq-win-x64-0.3.7.exe (0.3.7 is the version number that changes)
