> **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)](https://chatgpt.com/g/g-6a5b41f0a33881918be69e8b10f8b4ff-slide-maker-gpt). 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 before you ever see it. 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.) - 🧑⚖️ **Reviewed before you see it.** A non-negotiable actor–critic loop: 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. - 🎨 **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). What's rare is *editable **and** source-traced **and** critic-reviewed **and** bespoke* — together, in one file you own. 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](#what-makes-slide-maker-different). Recent updates: it now also reads **Word, Excel, CSV, images, and video/audio** (extraction-first — it never guesses a number off pixels), and handles a whole **book or very-long PDF** by triaging chapters around your deck's purpose instead of skimming.Intro video · Templates · What's different · How it works · Quick start · Troubleshooting

--- ## How to use the templates The gallery lives in the [slides_maker-site](https://github.com/addsumtech/slides_maker-site) repo under `templates/decks/`, English under `en/`, Chinese under `zh/`. Grab it once: ```bash git clone --depth 1 https://github.com/addsumtech/slides_maker-site.git ``` Two ways to use a template: **Option 1: point at it (simplest).** Put the template path in your request: ```text Use slide-maker. Follow the style of slides_maker-site/templates/decks/en/nvidia-overview/template.pptx and build a product intro from my product.md. ``` It parses the template's layout and visual system, then applies them to your content. **Option 2: register it for repeated use.** Copy a template you like into the local template registry, and slide-maker will list it as an option every time: ```bash # Claude Code users cp -r slides_maker-site/templates/decks/en/nvidia-overview ~/.claude/slide-templates/nvidia-overview # Codex users cp -r slides_maker-site/templates/decks/en/nvidia-overview ~/.codex/slide-templates/nvidia-overview ``` Use `en/` templates for English decks and `zh/` for Chinese ones. The layouts match; only the copy language differs. --- ## What makes slide-maker different AI presentation tools roughly fall into four categories. slide-maker only does the last one: | Category | Output | Editable element by element in PowerPoint? | | --- | --- | :---: | | Template fill-in | Content poured into a fixed template | Partially, limited by the template | | Image-based | One big picture per slide, packed into PPTX | No, each slide is a picture | | HTML presentation | Slides in a browser | Not a PPTX | | **Native editable (slide-maker)** | **Real text boxes, shapes, native charts** | **Yes, click anything and edit** | That table is about the *format*. A handful of newer tools now also emit native-editable PPTX — so "editable" alone no longer sets anything apart. What sets slide-maker apart is **what it does with that format**: it reads your real material and refuses to invent, it puts the deck through an independent review before you see it, and it composes each slide to your content instead of pouring text into a template. The rest of this section is those three, in order. ### A small team of agents: separate jobs, separate incentives slide-maker isn't one prompt doing everything. It's a set of **specialized agents**, each with a single role, deliberately kept independent so that no one mind both builds the deck and grades it: - **Content-planner**: the lead editor. It does the reading nobody else did and decides what each slide *says* — the takeaway, the evidence, the narrative arc — with every number traced to a source and a coverage gate that guarantees no key point in your material gets silently dropped (each one either lands on a slide or is flagged as consciously cut). Because the whole story flows through one mind, the deck holds together as an argument instead of a pile of slides. - **Slide-design (art director)**: a separate mind that decides how the approved story *looks* — each slide's visual form, the palette (one meaning per colour, deck-wide), typography, rhythm, icons, and where click-builds actually earn their place. It sketches each page from the content first and only then reaches for the component library, so decks come out designed, not templated. - **Critic**: an independent reviewer who did not build the deck. It judges the rendered slides through two lenses — content fidelity (a number that doesn't match the source, a key point gone missing) and design (cramped layout, weak contrast, a deck that's compliant but dead) — and sends fixes back. Having no stake in the draft is exactly what makes it honest. - **Arbiter**: for high-stakes decks, a second independent check that confirms a critic's finding is real before anything changes, so the loop fixes true problems, not noise. - **Asset-prep**: a build-time executor that materializes the plan's assets (figure crops, equation images, generated plates, icons) in parallel once you've approved the design plan. It makes zero design decisions, so even large decks build fast. The split is the point: a constructive planner proposes, independent judges dispose. That's why the deck you receive has already survived a review you never had to run. On top of that, it does four things most tools skip: - **It reads before it draws.** A paper gets read end to end, a repo starts from its README, and when you have no material it researches the topic online first. Every number and figure is traced back to a source, and you confirm a structure draft before any slide is drawn. It will not paste the abstract onto slide one and call it a day. - **It gets reviewed before you see it.** After generation, every slide is rendered to an image and handed to the independent critic. Cramped layout, weak contrast, numbers that don't match the source: all get sent back for fixes. You receive the deck only after the critic signs off. - **More than text stays editable.** Data charts default to native PowerPoint charts you can double-click and re-number. Formulas are typeset as editable native math text by default, not screenshots (only 2-D layouts like fractions and matrices fall back to a rendered image). Paper figures are cropped from the PDF as-is, never redrawn. - **Script and motion come included.** Presentation decks carry a full per-slide script in speaker notes, and bullets are native PowerPoint click builds. You can walk on stage with it. One more thing that matters if you iterate a lot: every deck is generated by a build script that ships next to the file. Change the focus, the slide count, or the template with one sentence, and it regenerates cleanly instead of you reworking slides by hand. And it gets more *yours* over time. When you keep steering a preference the same way across decks — vivid data with quiet chrome, no template-y cards, typeset equations — it records that as a portable taste profile: a plain file you own at the registry root, which you can read, edit, or delete line by line. Future decks read it as a default so you stop re-teaching the same thing. It only ever *seeds* a choice — whatever you say on the current deck always wins — and a brand-new user starts with a clean slate, no assumed style. To be plain about it: it does not promise a perfect deck in one shot. It promises to remove the expensive part (reading the material, planning the structure, laying out pages, making figures, writing the script) and to hand you a real file you can keep editing. The polish that remains is yours. That is exactly why the output is native PPTX. --- ## How it works 1. **It asks first.** Who is the audience, how long is the talk, live or self-read, what style. Short answers are enough. Say "you decide" if you are in a hurry — it then picks sensible answers itself and posts its picks before building, so a wrong guess costs you one glance, not a rebuild (only a missing topic or source still needs you). No material at all? Give it a topic and it will research online before anything else. 2. **It reads (or researches) the material.** Papers, docs, repos — and now Word / Excel / CSV / images / video, plus whole books via purpose-driven triage — are read faithfully: figures cropped from the PDF, key numbers verified line by line, nothing without a source on a slide. With only a topic, it researches current information online first, then works from that. 3. **You approve the story, then the look — right in the chat.** The content-planner posts a compact per-slide table (what each slide says, which figure carries it, how the deck flows); once you confirm the story, the art director posts the design plan (look, palette, per-slide form, motion) the same way. Two quick confirmations at the two cheapest moments to change direction — no plan files to open. 4. **It generates the PPTX.** Layout is guaranteed by code, with automatic layout checks both at build time and on the rendered output. Overflow, overlap, and font problems get caught there. 5. **An independent critic reviews it.** Rendered slides go to the critic agent (with an arbiter cross-checking on high-stakes decks), judged against presentation standards. Fixes land, the deck is re-checked, and only then is it delivered to `~/Downloads/
