I think he might mean SX Installer? Otherwise I have no idea what he's talking about.
Title installers on the Switch cause a lot of confusion, so hopefully I can help clear out that with this post.
Basically speaking, there are (more than) a few floating around and the most popular are:
Adubbz's Tinfoil (the text only one and first public open source title installer, aka the one you're talking about)
Blawar's Tinfoil (previously called DZ, the one SX Installer is based on)
SX Installer (Self explainatory)
Lithium (Slimmed down version of Blawar's Tinfoil)
Goldleaf (based on Xortroll's fork of Adubbz's Tinfoil, also has a GUI)
There's been a lot of scene drama about various installers, naming and stuff so I'll not touch any of that, however keep in mind that in the above list the only currently unsupported one is Adubbz's Tinfoil (however some people still like to use an old version with added USB install support due to it being remarkably stable for being a WIP version).
