How to use GPT Image Inpaint & Generative Fill
- 1
Upload your comic still
Drop in a PNG or JPG — a panel, character portrait, cover, or illustration. Sign in and the canvas loads your image ready to edit.
- 2
Paint the region to change
Draw a box or brush over the exact area you want to edit, then add a short prompt describing the new pose, prop, expression, or background detail.

Generate, compare, and download
The first generate each day is free, then 20 Tab Story credits each. Compare the result, roll back if needed, and download when the local edit looks right.
What is GPT Image Inpaint & Generative Fill?
The page is almost right except the fingers, the shop sign, or one extra face in the crowd. You do not owe the model a whole new splash. This Infinite Canvas page is Tab Story’s public AI inpaint editor for comic stills: mark one region, generate that patch, keep composition and line.
It is the same Refine editor creators use inside the studio, opened here so you can fix a panel, portrait, or cover without starting a project. Opening the canvas and painting a mask are free after you sign in. Signed-in accounts get 1 free generate per day on this tools page; extra generates use 20 Tab Story credits — GPT, Banana, Seedream, and the fallback model share that price.
If the whole splash is the problem, regenerate the panel instead of carving holes. The longer product story lives on Fix the Hand. Keep the Splash.. When you want a chapter, not a patch, start from Create.
FAQ
Can I inpaint just one part of a comic panel?
Yes. Upload the still, paint or box the region that should change, and generate. The rest of the frame stays put. That is the job of this Infinite Canvas page: local AI redraw, not a full-page reroll.
How do I fix AI-generated hands without regenerating the page?
Mark a tight box around the hand or fingers, say what should stay (face, sleeve, the object being held), and generate. Opening and annotation are free after sign-in. 1 free generate per day on this tools page, then 20 Tab Story credits each.
Is this AI inpaint tool free?
Opening the canvas is free after you sign in. Painting a mask does not cost credits. Signed-in accounts get 1 free generate per day on this tools page; extra generates use 20 Tab Story credits, the same for GPT, Banana, Seedream, and the fallback model.
Which models does it use? Is GPT Image included?
Yes. Pick GPT Image, Nano Banana, or Seedream on the canvas. All three cost the same here: 1 free generate per day, then 20 credits. Tab Story is not affiliated with OpenAI; it runs the model on the region you mark.
Do I need to start a comic first?
No. This page is a standalone regional image editor. Sign in with a Tab Story account, upload any still, and download the result. You can take it into a drawing app or into Tab Story later. Nothing is written into a comic project from here.
When should I regenerate the whole panel instead?
When layout, lighting, or the whole pose is wrong. Inpaint will not rescue a splash that missed. Use panel regenerate for that job, then come back here for the one remaining defect.
How is this different from Photoshop generative fill?
Same idea — mark a region, describe the change, keep the rest — built for comic stills and wired to Tab Story credits and models. It is not a desktop painting suite: no tone layers, no lettering, no Clip Studio replacement. Studio Refine is the same editor writing back onto a project; this page is the public download door.
Is this a Magma Infinite Canvas alternative?
Same two words, different job. Magma is a collaborative general-art canvas. Tab Story Infinite Canvas is a signed-in inpaint editor for one region of a comic still. Opening and masking are free; 1 free generate per day, then 20 credits each. It is not a multiplayer whiteboard.
Can this replace CLIP STUDIO PAINT or Photoshop?
No. Keep CLIP STUDIO for tones, lettering, and print. Keep Photoshop / Firefly for photo composites. This page is the scalpel when an AI comic still is almost right except a hand, sign, or face.
How is this different from Leonardo AI Canvas, Canva Magic Studio, ChatGPT Images, or Midjourney?
Leonardo and ChatGPT are general image editors. Canva is layouts. Midjourney rerolls whole images. Here you upload a comic panel, mark a region, and download the patch. Composition stays. 1 free generate per day, then 20 Tab Story credits each.
