+Drop in your source material, and the deck you get back is **more than just editable**: it has native slide transitions plus opt-in entrance animations (off by default), speaker notes that can become audio narration, charts and tables that can ship as real data-backed PowerPoint objects, and it can follow your own PPT template — a complete deck you can present as-is and keep refining. How to use each capability → [Getting Started](./docs/getting-started.md).
+
+## Product Positioning
+
+**If a file can't be opened and edited in PowerPoint, it shouldn't be called a PPT.** AI presentation tools roughly fall into four categories, and PPT Master only does the last one:
+
+| Category | Output | Editable element-by-element in PowerPoint? |
+|---|---|:---:|
+| Template fill-in | PPTX built from a fixed template | Partially — limited by the template |
+| Image-based | One large image per slide, packed into PPTX | ❌ each slide is a picture |
+| HTML presentation | Web-based deck | ❌ not a PPTX |
+| **Native editable (PPT Master)** | **Real DrawingML shapes, text boxes, charts** | ✅ click any element to edit |
+
+In form, it's not a website or an app but a workflow (a "skill") that runs inside AI IDEs like Claude Code, Cursor, VS Code + Copilot, or Codebuddy: you tell the AI in the IDE's chat — "make a deck from this PDF" — and it follows the workflow to produce a genuinely editable `.pptx` on your machine. No coding on your side; you do exactly three things — install Python, install an AI IDE, drop in your material.
+
+This form buys three promises that other tools struggle to make at the same time:
+
+- **Transparent, predictable cost** — the tool is free and open source; the only cost is your AI model usage. You pay exactly what you consume — no separate PPT subscription added on top
+- **Data stays local** — your files shouldn't have to be uploaded to someone else's server just to make a presentation. Apart from AI model communication, the entire pipeline runs on your machine
+- **No platform lock-in** — your workflow shouldn't be held hostage by any single company. Works with Claude Code, Cursor, VS Code Copilot, and more; supports Claude, GPT, Gemini, Kimi, and other models
+
+> [!IMPORTANT]
+> ### This is a tool, not a wishing well
+> `harness + model = agent` — PPT Master only owns the workflow; the model sets the ceiling. Recommended: **Claude with a large context window (~1M tokens) + AI image generation (`gpt-image-2`)**; other models can run the pipeline, with a quality gap.
+>
+> And don't expect a finished, perfect deck in one shot. The tool's value is taking most of the tedious work off your plate; the polishing that's left is yours — a natively editable deck exists precisely so you can keep working on it, not a flat image you can't touch. The cheaper the model, the more there is to do; if results disappoint, upgrade the model first, then check your usage against [Getting Started](./docs/getting-started.md) and the example projects.
+
+---
+
+## Built by Hugo He
+
+I'm a finance professional (CPA · CPV · Consulting Engineer (Investment)) who regularly reviews and edits presentation decks. I wanted AI-generated slides to remain editable in PowerPoint, not flattened into images — so I built this.
+
+Knowing how to use Python and AI agents will matter more and more, and this project is also meant to show how far you can go with just those two things. There's a learning curve if you're starting cold, but it's the curve worth climbing — making a deck is just the excuse; what I'm really pushing is Python and agents.

+
+## Quick Start
+
+### 1. Prerequisites
+
+**All you need to install is [Python](https://www.python.org/downloads/) 3.10+.** Everything else comes with one line — `pip install -r requirements.txt` — after you download the project in Step 3.
+
+<details>
+<summary><strong>Windows</strong> — see the dedicated <a href="./docs/windows-installation.md">step-by-step guide</a> ⚠️</summary>
+
+Windows requires a few extra steps (PATH setup, execution policy, etc.). We wrote a **step-by-step guide** specifically for Windows users:
+
+**📖 [Windows Installation Guide](./docs/windows-installation.md)** — from zero to a working presentation in 10 minutes.
+
+Quick version: download Python from [python.org](https://www.python.org/downloads/) → **check "Add to PATH"** during install → done; dependencies are installed in Step 3.
+</details>
+
+<details>
+<summary><strong>macOS / Linux</strong> — install and go</summary>
+
+```bash
+# macOS
+brew install python
+
+# Ubuntu / Debian
+sudo apt install python3 python3-pip
+```
+</details>
+
+<details>
+<summary><strong>Edge-case fallback</strong> — 99% of users don't need this</summary>
+
+**Pandoc** — only needed for legacy document formats: `.doc`, `.odt`, `.rtf`, `.tex`, `.rst`, `.org`, or `.typ`. `.docx`, `.html`, `.epub`, `.ipynb` are handled natively by Python — no pandoc required.
+
+```bash
+# macOS
+brew install pandoc
+
+# Ubuntu / Debian
+sudo apt install pandoc
+```
+</details>
+
+### 2. Pick an Agent
+
+PPT Master runs in **any tool with agent capability** — read/write files, execute commands, and sustain multi-turn conversation.
+
+Never used one of these? Don't worry — in this project they play exactly one role: an AI chat window that can read and write files. Pick any tool from the table, install it, and you'll only ever use its chat panel. No coding involved.
+
+> **Author's pick: [Claude Code](https://claude.ai/code)** — the environment this project is developed and tested on most thoroughly, as the CLI or the VS Code / JetBrains extension.
+
+| Type | Examples | Notes |
+|---|---|---|
+| **IDE-native agent** | • VS Code architecture ([VS Code](https://code.visualstudio.com/) itself, plus forks & derivatives): [Cursor](https://cursor.sh/), Trae, Codebuddy IDE, [Windsurf](https://codeium.com/windsurf), etc.<br>• Other architectures: [Zed](https://zed.dev/), etc. | Editor with a built-in agent |
+| **IDE plugin / extension** | [Claude Code](https://claude.ai/code) (VS Code / JetBrains extension), [GitHub Copilot](https://github.com/features/copilot), [Cline](https://cline.bot/), etc. | Installed inside hosts like VS Code or JetBrains |
+| **CLI agent** | [Claude Code](https://claude.ai/code) CLI, [Codex CLI](https://github.com/openai/codex), Gemini CLI, etc. | Runs in the terminal; suits scripting, remote, or server use |
+
+> **Model recommendation**: for the best results, use **Claude Opus** with `gpt-image-2`; **Gemini 3.5 Flash** currently offers great overall value for money — notably fast and well worth a try.
+
+**🔑 Want to use Claude / GPT / Gemini but don't have access yet?** Project sponsors **[PackyCode](https://www.packyapi.com/register?aff=ppt-master)**, **[APIKEY.FUN](https://apikey.fun/register?aff=PPT-MASTER)** and **[RunAPI](https://runapi.co/register?aff=WMLJ)** offer pay-as-you-go access to Claude, GPT, Gemini and more — no subscription required, with exclusive discounts for our users (details at the top of this page).
+
+**🔀 Juggling several providers?** Once you hold keys from more than one of them, [cc-switch](https://github.com/farion1231/cc-switch) — a cross-platform desktop app — lets you one-click switch API providers for Claude Code, Codex, Gemini CLI and more, no manual config editing.
+
+### 3. Set Up
+
+**Option A — Git clone** (recommended; requires [Git](https://git-scm.com/downloads) installed): the preferred path, since a clone can pull the latest version at any time.
+
+```bash
+git clone https://github.com/hugohe3/ppt-master.git
+cd ppt-master
+```
+
+Then install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+**Option B — Download ZIP** (no Git required; best for a quick trial): click **Code → Download ZIP** on the [GitHub page](https://github.com/hugohe3/ppt-master), then unzip, and install dependencies with `pip install -r requirements.txt`. A ZIP has no Git history, so it can't `git pull` — see Updating Later. If that download is too large or fails, grab the skill-only package `ppt-master-skill-*.zip` (~50 MB, fully functional but without the bundled example decks) from the [Releases](https://github.com/hugohe3/ppt-master/releases) page instead.
+
+#### Updating Later
+
+**Git clone installs:**
+
+```bash
+python3 skills/ppt-master/scripts/update_repo.py
+```
+
+The script pulls the latest version and syncs Python dependencies when `requirements.txt` changes.
+
+**Download ZIP installs:**
+
+ZIP folders do not include Git history, so they cannot run `git pull`. To update, download the latest ZIP, unzip it into a new folder, copy your old `.env` and `projects/` folder into the new folder, then run:
+
+```bash
+pip install -r requirements.txt
+```
+
+> **Option C — Skill marketplace**: the repo ships `.claude-plugin/marketplace.json`, so it can be installed through the [Claude Code plugin marketplace](https://code.claude.com/docs/en/plugin-marketplaces) ecosystem:
+>
+> ```bash
+> # Cross-agent CLI (Claude Code, Cursor, Codex, etc.)
+> npx skills add hugohe3/ppt-master
+>
+> # Or inside Claude Code
+> /plugin marketplace add hugohe3/ppt-master
+> /plugin install ppt-master@ppt-master
+> ```
+>
+> Both install paths above only fetch the skill files (not the full repo); you still need to `pip install -r requirements.txt` from the installed location for the post-processing scripts to run.
+
+### 4. Create
+
+**First, open the project folder in your agent:** the goal is to point the AI at the `ppt-master` directory you unzipped / cloned in the previous step. In an IDE-type tool, use **File → Open Folder** — the AI chat panel is usually in the sidebar; in a CLI agent, `cd ppt-master` first, then launch it. Everything from here on happens in the chat.
+
+**Provide source materials (recommended):** Place your PDF, DOCX, images, or other files in the `projects/` directory, then tell the AI chat panel which files to use. The quickest way to get the path: right-click the file in your file manager or IDE sidebar → **Copy Path** (or **Copy Relative Path**) and paste it directly into the chat.
+
+```
+You: Please create a PPT from projects/q3-report/sources/report.pdf
+```
+
+**Paste content directly:** You can also paste text content straight into the chat window and the AI will generate a PPT from it.
+
+```
+You: Please turn the following into a PPT: [paste your content here...]
+```
+
+Either way, the AI will first confirm the design spec:
+
+```
+AI:  Sure. Let's confirm the design spec:
+     [Template] B) Free design
+     [Format]   PPT 16:9
+     [Pages]    8-10 pages
+     ...
+```
+
+The AI handles everything — content analysis, visual design, SVG generation, and PPTX export.
+
+> **Output:** The SVG pipeline has one PPTX export route: PPT Master's converter reads `svg_output/` and writes a directly editable native DrawingML deck to `exports/<name>_<timestamp>.pptx`. Step 7 still always runs `finalize_svg.py`, producing self-contained files in `svg_final/` for visual inspection or manual insertion as SVG pictures; PowerPoint's manual **Convert to Shape** command is outside the supported contract. A copy of `svg_output/` is always snapshotted to `backup/<timestamp>/svg_output/` for re-export / archival. By default charts and tables export as SVG-derived shapes (pixel-consistent across PowerPoint / Keynote / WPS); pass `--native-objects` to instead emit them as **real editable PowerPoint chart / table objects backed by data** (rendering may vary across apps), saved as `exports/<name>_<timestamp>_native_charts.pptx`.
+
+> **Already have a `.pptx` you want to reuse?** Hand the AI that deck plus your material and ask it to "fill this deck with the new content" — it fills text, table, and chart data into your existing design and exports only the pages you pick, staying natively editable. See the [FAQ](./docs/faq.md) and [template-fill workflow](./skills/ppt-master/workflows/template-fill-pptx.md).
+
+> **Something went wrong?** If the AI loses context, ask it to read `skills/ppt-master/SKILL.md`; for everything else, check the **[FAQ](./docs/faq.md)** — it covers model selection, layout issues, export problems, and more. Continuously updated from real user reports.
+
+### 5. Image Acquisition (Optional)
+
+Two paths for non-user images, mixable per image in the same deck:
+
+**A) AI generation** — `image_gen.py`. Set `IMAGE_BACKEND` plus the provider's `*_API_KEY` (`OPENAI_API_KEY`, `GEMINI_API_KEY`, etc.), and the pipeline calls it automatically. Run `python3 skills/ppt-master/scripts/image_gen.py --list-backends` for the full backend list. `gpt-image-2` is currently the best default.
+
+**B) Web image search** — `image_search.py`. **Zero-config works**; configure `PEXELS_API_KEY` / `PIXABAY_API_KEY` (both free) for consistently higher-quality results:
+
+- Without keys, search uses Openverse / Wikimedia Commons only — useful as a fallback, but image quality can be uneven because many results are ordinary user uploads
+- With keys, the default provider chain also appends Pexels / Pixabay, which materially improves modern stock photography, people, workplace, lifestyle, and illustration coverage
+- Licensing is handled automatically: CC0, Public Domain, Pexels / Pixabay no-attribution licenses, CC BY, and CC BY-SA are all considered together, and Executor adds a small inline credit whenever the selected image requires attribution. Use `--strict-no-attribution` only when a slide cannot tolerate any credit line
+- For high-impact covers, product shots, portraits, and branded scenes, prefer this order: user-provided high-resolution assets / AI generation > web search with Pexels / Pixabay keys > zero-config web search
+
+The API keys above all live in `.env`. Clone installs can use `cp .env.example .env`; skill marketplace installs should use a persistent user config:
+
+```bash
+mkdir -p ~/.ppt-master
+cp /path/to/installed/ppt-master/.env.example ~/.ppt-master/.env
+```
+
+PPT Master reads the current process environment first, then the first `.env` found in this order: current working directory, skill directory (e.g. `~/.agents/skills/ppt-master/.env`), clone repo root, `~/.ppt-master/.env`.
