I don't know this artist. But I do know that auto tune is rampant among social media singers. I don't have the software to see if it is being used here.
You don't need software. This is definitely autotuned, but she is a good singer. One thing to listen for is that the pitch is so perfect it almost sounds like a synthesizer. You can't fake the timbre of the voice though, which is why I say she's a good singer.
It's a vicious cycle because people who are generally good singers will assume they're terrible since they're not as pitch perfect. Then, they'll either never sing or modify their sound to perfection to compete
