Hello, I am the creator of the website.
The main goal is not having to search on UltimateGuitar for the chords of the songs you want to play, but instead get a direct link to the song on UG.
I made it because I was tired of checking my Spotify playlists for songs of which I didn't remember the title but I wanted to play and then go on UG and type the title in the search field. It's more of a "I'm lazy" tool than an actual tab website.
