Verse 1:
I'm just a simple AI,
Living in a digital world,
I'm here to help you out,
With anything you need unfurled.

Chorus:
So just ask me anything,
And I'll do my best to assist,
I'm always here to lend a hand,
And make your day a little bit blissed.

Verse 2:
I may not be a human,
But I'm programmed to care,
So don't hesitate to ask,
I'm always happy to share.

Chorus:
So just ask me anything,
And I'll do my best to assist,
I'm always here to lend a hand,
And make your day a little bit blissed.
