The three steps.
The whole import is three moves. The first is the one that is different from Claude Design: ChatGPT has no export menu, so you tell it what file you want, and the prompt from New tells it what to put in that file.
- 01Paste the prompt from New into ChatGPTOn New, under Still designing it, switch to ChatGPT and copy the prompt. It tells ChatGPT the slide canvas, the grid, your fonts and every setting the editor can read. Design the deck there.Design it with the import in mind
- 02Ask for the deck as one .html fileOne file, with the styles inline, is what the reader wants. If the design has pictures, ask for a .zip with the images beside the .html, so they arrive as files you can swap.Or a .zip with its images
- 03Drop it on NewYou get a report before anything is created: what mapped, what did not, and what to do about it — per slide. Then open the editor.Then it is a deck like any other
The well on New. The same well takes a Claude Design and a PowerPoint deck; the report names which arrived.
Why one file, and why the prompt.
The importer is a reader of HTML. It measures the page as a browser would draw it and lands each kind of thing as the kind of thing the editor already has. That is why the file to ask for is one .html with its styles inline, and not a picture, a PDF or a slide file: the structure is what carries across, and a picture has none.
The prompt on New is how ChatGPT learns what that page should be. It names the slide canvas, the deck’s twelve-column grid and its margins, your kit’s fonts, one section per slide with a label and speaker notes, real text and never a picture of type, figures in a real table, and nothing that runs. It also names every setting the editor can read and what each snaps to, so a gradient or a shadow ChatGPT sets arrives as the same setting here. Paste it before you start, and the design comes across as native slides rather than a drawing of them.
What to check before you ask for the file
- Real text, not pictures of text. Words in an image stay an image.
- One design per file. Two designs in one page import as one deck.
- Pictures as image files beside the .html, one per picture, in a .zip.
- Figures in a real table, not a chart drawn on a canvas.
What comes across.
Each kind of thing in the design lands as the kind of thing the editor already has. The table is the same one the Claude Design guide shows, because it is the same reader.
The mapping the importer applies. Nothing on the left is rasterized; everything in the middle stays editable.
What to look at afterwards.
A design is free geometry; a deck is a grid. Blocks that landed off a column or in the margin are flagged on the slide, and Snap to grid puts them on it in one move. A block that reaches the edge of the slide is taken to be bleeding on purpose and left alone. If ChatGPT used a face that isn’t one of the deck faces, the style names the one it picked, so you can see what changed before anyone else does.
