No. The browser reads and processes the audio itself with the Web Audio API. Nothing is sent to a server, so there is no limit on how often you use it.

Does it change the pitch?

Yes, like the trend: slowing the playback lowers the pitch too, which is the sound people know as slowed + reverb.

What settings should I use?

85% speed and about a third reverb is the classic sound. Go slower and wetter for a dreamier version.

Can I use the result commercially?

Only if you own the song or have the rights to it. The tool changes the sound, not who owns it.
