Text within image editing

I am looking for an extension to Stable Diffusion XL Turbo for the following things :

  • I couldn’t find a way to take an existing image and modify it, and have to start with a seed, which is understandable.
  • I am specifically looking at modifying text values within the image. I am unsure of how to go about doing this, or is there a specific model which I can leverage for the purpose?

I did try some alternates which do take in the image inputs but didn’t get me the modification expected.

Any nudge or input on this, will be extremely helpful.
