# Cthulhu # Cthulhu
## Note
If you somehow stumbled across this while looking for a desktop screen reader for Linux, you most likely want [Orca](https://orca.gnome.org/) instead. Cthulhu is currently a supplemental screen reader that fills a nitch for some advanced users. E.g. some older QT based programs may work with Cthulhu, and if you use certain window managers like i3, Mozilla applications like Firefox and Thunderbird may work better.
