TL;DR. Infinite Canvas is a signed-in editor: upload or drop a still, mark a region, generate that patch with the models on the canvas. Opening it is free. 1 free generate per day, then 20 credits each. It is a scalpel, not a second comic app.
What regional inpaint looks like
Mark one region. Same gesture as Photoshop Generative Fill / Firefly — for a comic still.Before / after: keep the splash, patch the AI hand. Midjourney would reroll the sky.Mask the sign. The street stays. That is inpaint, not a Leonardo or ChatGPT whole-image edit.

When to use this vs something else
If…
Use Infinite Canvas
Use something else
One region is wrong; the rest of the page is worth keeping
Mark the region and generate the patch
—
Layout, lighting, or the whole pose missed
—
Regenerate the panel — or Midjourney if you want a new vibe
You need tones, lettering, or an offline painting suite
—
CLIP STUDIO PAINT / Photoshop
You want a chapter, not a patch
—

If you know…
They are for
Tab Story Infinite Canvas
Photoshop Generative Fill / Adobe Firefly
Desktop photo composite. Creative Cloud.
Browser inpaint on a comic still. 1 free generate a day, then 20 credits. Download.
CLIP STUDIO PAINT
Tones, lettering, print, a full painting suite.
Not a replacement. Use this when one region of an AI still is wrong.
Magma Infinite Canvas
Collaborative general-art canvas. They used the two words first.
Solo comic-panel inpaint. Not a multiplayer whiteboard.
Leonardo AI Canvas
General AI canvas / inpaint playground.
Comic stills and Tab Story credits. Same mark-a-region idea, comic desk.
Canva Magic Studio
Decks, social layouts, brand kits.
No brand kit. A panel, a mask, a patch.
ChatGPT Images / Gemini
Chat-first image edit.
Upload a panel, mark a box, generate. No thread required.
Midjourney
Whole-image vibe and remix. The sky rerolls.
Keep composition. Patch one defect.
The most honest comic tool we shipped
Every AI comic person has a folder of “almost.” The composition sang. Then you saw the hand. Whole-image rerolls are how you lose the sky you cannot get back.
Infinite Canvas exists for that folder. You stay on one still. You annotate what is wrong. You generate the patch. The rest of the panel is not a dice roll this time.
How it actually runs
Sign in. The canvas is not a public playground.
Upload a panel, a portrait, or an illustration — or come from Create’s Infinite Canvas mode.
Mark the region. Auto-annotate can suggest marks; you still decide what is fair game.
Generate. The first generate each day is free, then 20 credits each — not an unlimited free inpaint loop.
If the whole page is the problem, go back to panel regenerate instead of carving twenty holes.
It is not a painting suite
There is no offline desktop, no tone-layer system, no lettering tool hiding in the canvas. If you need Clip Studio, you already know. Use the canvas when one region is the only thing standing between you and posting.
