The one I’ve been using is IOPaint-LaMA, which is great for both ghost signature removal as well as cleaning up other oddities you might find in your generations (like extra limbs, hair sticking out of the top of hats/helmets, and weird background artifacts)

Oh thank you. This well be vary useful in the future. When I do my generated on my phone.

Inpaint sketch is also a good one, or alternatively, I’ve had quite good success with adding “signature, watermark” to negative prompts.

As mentioned above, here’s a link to Photopea.

It’s basically PhotoShop in a browser. If you’re used to PhotoShop you’ll find the learning curve is almost flat. For me the hardest part was learning to trust that it would do what I asked - like I expected to have to go through hoops to get files into or out of it, but Open and Close are in the File menu and work exactly as if you were running PhotoShop on your own machine. And the saved files don’t add any kind of watermarks.

PS: It works in browsers on iPads, too. Super handy!

To note, while Photopea is used here (and it’s even embeddable in SD-Web-UI!), most modern digital art programs have similar healing / magic eraser tools: Pixler, Fotor, of course Photoshop and CorelDraw… and even MSPaint!

Another alternative is dedicated tools like Lama Cleaner, but Photopea is overall faster and easier to use.

Ghost Signatures are these text artifacts that sometimes pop up in the corners of AI generated images. They are unsightly, and are counted as a generation error on Tantabus. But there is a very easy solution to rid your picture of them before uploading and all you need is your trusty browser:

This quick edit can be performed in a few minutes and most of the time not even one. So help us fight the good cause and get rid of these nasty errors.
