<Comment>

“Singing voices carry countless emotions.”

“NAYUTA” is a voice AI software that embodies the voice and feelings of me, "nayuta," who has sung countless songs across the vast ocean of the internet.

I’ve carefully preserved those many songs I’ve sung and breathed new life into them through AI.

The name “NAYUTA” reflects my hope for infinite musical possibilities.

I’m truly excited to see many new songs born through the creativity of many artists.
