slide-maker: turn a paper, a repo, a doc, or just a topic into a native PPTX you can present

The slide-maker that reads your actual work, never invents a number, ships fully-editable native PowerPoint, and won't hand it over until an independent critic signs off.

Chat with it in Codex or Claude Code — or, with zero install, in ChatGPT via the slide-maker (addsum studio). It isn't one prompt guessing at slides: a small team of specialized agents reads your paper / repo / doc (or researches the topic when you have none), plans the story, designs each slide around it, builds a real .pptx, and puts it through an independent review you size after seeing the first render.

Most AI-PPT tools race to look pretty in seconds. slide-maker optimizes for the four things that actually matter when the deck is yours to defend:

• 🔍 Reads your source — doesn't invent it. Every number and figure traces back to your material; it won't make up a statistic to fill a slide. (The failure mode of every "expand a topic" tool — one popular assistant printed 43% growth where the real figure was 12%.)
• ✏️ A real PowerPoint, not a screenshot. Every text box, shape, native chart and equation is a click-to-edit object — nothing flattened to an image. (Many "export to PPTX" tools quietly turn a third of your slides into uneditable pictures.)
• 🧑‍⚖️ Independently reviewed — you size it, deck in hand. A separate critic tries to break the deck — cramped layout, weak contrast, a number that doesn't match the source — and sends fixes back. Not the author model grading its own homework. You pick how hard (or skip it) after seeing the first render.
• 🎨 Designed around your content, in any language — on any canvas. Composed slide by slide — matching your template or designing a clean one — for a research talk, a thesis defense, or a product pitch. Not your text poured into a stock layout. And not only 16:9: the same skill recomposes to 4:3, square 1:1, rednote (小红书) 3:4 cards, 9:16 story covers, and A4 print one-pagers, each with its own safe zones and layout logic.

Native-editable PPTX is now table stakes; several tools do it. Rarer is a deck that is editable, source-traced, critic-reviewed and composed for your content at the same time. Honest limits: no zero-setup cloud, no share links, no animated web backgrounds — it makes a file, run locally, that opens and edits cleanly in real PowerPoint/Keynote. See what's different.
