Begins from a minimal starter HTML template with no content assumptions.
Upload a reference file
Accepts a PDF, a PNG/JPEG/WebP image, or an SVG, up to 20 MB. PDFs and raster images are actually shown to the model as visual input; SVG falls back to a filename/context note since the vision model can't read SVG directly.
From an existing document
Reuses a Document Editor document as reference material-its raw source PDF (or brand style, if it has none)-then lets you pick the build type yourself. Document Editor's own "Send to Interactive" button also offers preserving or reflowing the exact rendered layout, not just this reference mode.
Build type (optional)
Click-through slideshow, Scroll-driven story, Interactive document, or App-like prototype-a steer for the first instruction, not a locked output mode. Quick-start shortcuts Slides and Document pre-fill a starting prompt and tell the builder outright which shape to produce-a paged deck or a continuous scrolling document.
A Document Editor project can also hand off content to Interactive directly via Send to Interactive, choosing a document, page, or range to bring across.
