An OpenAI-published generated browser tool that turns typed Markdown into a slide preview, using lines of three hyphens as slide breaks.

What can you do with it?
Inspect a generated document-to-preview workflow with Markdown editing, live slide rendering, previous/next and keyboard navigation, theme selection and browser fullscreen controls.
What should you know before using it?
A small custom Markdown parser powers this preview/presentation demo. There is no built-in PPTX, PDF or HTML export. Only the theme is saved to localStorage; the document restarts from a sample. A separate browser record covers a two-slide synthetic document and previous/next navigation, not full Markdown compatibility. Remote images can need network access.

Creator: OpenAI
OpenAI describes this collection as application code generated from single GPT-5 or GPT-5.2 prompts without handwritten application code. The exact pinned manifest identifies this base example but does not name an individual model checkpoint. This is publisher-reported provenance, not an independent authorship audit.
Runtime: Single HTML/CSS/JavaScript artifact with a textarea and client-side rendering. The demo HTML matched the pinned source at source review. A later browser check rendered two typed slides and navigated between them; fullscreen, theme persistence, images and broader syntax were not tested.

Typed Markdown produced two slides with working previous/next navigation.
Replace the initial sample with two synthetic slides separated by a line containing three hyphens.
The preview updated to Slide 1 of 2, with the Sample deck heading and its paragraph.
Click Next slide.
The counter showed Slide 2 of 2. The Second slide heading and an Apples/Oranges bullet list were visible.
Click Previous slide.
The counter returned to Slide 1 of 2 and the first heading and paragraph reappeared.
Scope and limits: This checks basic heading/paragraph/list rendering, the slide delimiter and two navigation buttons using synthetic text. It does not test broader Markdown conformance, images, fullscreen, keyboard shortcuts, persistence or mobile behavior. Source review found no built-in file-export feature; no export was attempted.
Observed second slide and two-slide counter beside the synthetic Markdown input. Demo published by OpenAI.
