🆕 As a finance professional (CPA · CPV · Consulting Engineer (Investment)), I drew on my expertise and project experience to build a tool website: Construction Project Economic Evaluation (in Chinese) — enter your project data and get a full financial evaluation online: investment, revenue, cost, debt service, profit, cash flow and balance sheet statements, plus IRR, NPV, sensitivity and break-even analysis, exportable to Excel / Word. Built for energy projects such as wind, solar and storage, with a general-purpose mode for other projects. The site is in an early trial phase; the first 100 accounts get 3 free runs, later accounts get 1.

This project is kept free and open source with the support of Kimi, PackyCode, APIKEY.FAN, RunAPI, APIMart and other sponsors.

Editable is already table stakes — what sets PPT Master apart is native depth. It hands you a real PowerPoint: slide masters, native shapes, data-backed charts and tables — not flat text boxes, and not a filled-in template. It also does more than lay slides out nicely — it reasons the argument into shape first, then designs; and that native depth keeps converging with PowerPoint itself, adding more of its native capabilities release after release. In form, it's a workflow that runs inside any agent-capable AI tool: hand the AI your topic or material, and it generates on your machine — your data stays local, no platform or model lock-in. How it works and where the limits are → Product Positioning.

Quick Start · Live Demo · Examples · FAQ · Roadmap

Pixel Art — Chinese breakfast atlas: AI sprite sheets, HUD panels, Morph and 8-bit sound cues

Technical Blueprint — Transformer paper walkthrough: diagrams, native formulas, notes and animations

Brand Template — China Telecom 2025 results on the company's own deck template, with a native-chart export

_{Every example is a single pass with no manual polish; downloading a .pptx and opening it in PowerPoint is the fastest way to see what it can really do.

Editable is now table stakes — the real question is how much of PowerPoint you actually get. PPT Master delivers PowerPoint's native object model itself, and in depth: native shapes and connectors with working adjustment handles, data-backed charts and tables on demand, and the full text / picture / fill / effect model — click any element and keep editing it as a native PowerPoint object; and through the template / structured route, it can hand you a deck with real slide masters and layouts (p:sldMaster / p:sldLayout inheritance).

And that depth is a direction of travel, not a fixed checklist. PPT Master's north star is to keep converging with PowerPoint itself: an ongoing effort to build and integrate more of PowerPoint's native capabilities, release after release, closing the gap between what an AI can generate for you and what you could build by hand in PowerPoint. The PowerPoint ↔ SVG Mapping Guide is the honest, feature-by-feature record of how far that reaches today — and SmartArt is a deliberate omission, not a gap.

In form, it's a workflow (a "skill") that runs inside any agent-capable AI tool: tell it in chat — "make a deck from this PDF" — and it runs the workflow on your machine and exports a natively editable .pptx. No coding on your side; you do exactly three things — install Python, install an AI tool, drop in your material.

Generating a new deck from source documents is the main pipeline, but not the only route. PPT Master can also distill reusable brand / style / layout / deck templates from your references, fill an existing .pptx with new content while preserving its design, and add native transitions, animations, and narration to a finished deck — each route with an explicit contract for what gets preserved. How to use each capability → Getting Started.

On top of that native depth, this form comes with three promises:

• Transparent, predictable cost — free and open source; the only cost is your AI model usage, with no PPT subscription on top
• Data stays local — apart from AI model communication, the entire pipeline runs on your machine
• No platform lock-in — any agent-capable AI IDE can drive it; Claude, GPT, Gemini, Kimi, and other models all work

Why you'd choose it, and where it isn't the right fit → Why PPT Master; the long-term capability boundaries behind these promises → Project Positioning.

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.

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 — the environment this project is developed and tested on most thoroughly, as the CLI or the VS Code / JetBrains extension.

Model recommendation: for the best results, use Kimi K3 (or Claude) to drive the pipeline, paired with AI image generation — gpt-image-2 (OpenAI) or gemini-nano-banana-2.1 (Google). Kimi Code, the project sponsor, is a great pick for pay-as-you-go access.

🔑 Want to use Claude / GPT / Gemini but don't have access yet? Project sponsors PackyCode, APIKEY.FAN and RunAPI 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 — a cross-platform desktop app — lets you one-click switch API providers for Claude Code, Codex, Gemini CLI and more, no manual config editing.

Option A — Git clone (recommended; requires Git installed): the preferred path, since a clone can pull the latest version at any time.

git clone https://github.com/hugohe3/ppt-master.git
cd ppt-master

Then install dependencies:

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, 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 (~56 MB, fully functional but without the bundled example decks) from the Releases page instead.

Git clone installs:

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:

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 ecosystem:

# 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.

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...]

By default—unless you explicitly request quick generation—the AI first confirms 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.

Quick generation (skip the confirmation round trip): say so explicitly and the AI goes straight to authoring and export.

You: Quickly generate a 5-page deck from projects/q3-report/sources/report.pdf — no need to confirm with me

Whatever you state explicitly is followed; whatever you leave unspecified the agent decides on its own instead of asking. It still converts sources, fills factual gaps, applies the shared visual baseline, and uses images/icons/native shapes/charts/tables/PowerPoint-native inline or block formulas as needed — it drops interaction and durable planning, not presentation capability. It is one-pass and non-resumable, and there is no svg_final/ preview. Full guide → Quick mode.

Output: the deck lands in exports/<name>_<timestamp>.pptx as natively editable DrawingML; the default flow also writes self-contained page previews to svg_final/. Charts and tables ship as editable shapes by default; pass --native-charts-and-tables for data-backed PowerPoint Chart / Table objects with Edit Data, saved as a separate _native_charts_tables.pptx. Formulas compile to editable OMML for PowerPoint 2010+. Backups, notes, animation and narration switches, and the non-PowerPoint boundaries → FAQ.

Already have a .pptx you want to reuse? Give the AI the deck and material and ask it to "fill this deck with the new content" — Edit Native PPTX keeps the design and unchanged pages byte-for-byte, edits chosen pages, supports selection/reordering, and can add notes or narration. See the FAQ and workflow.

Something went wrong? If the AI loses context, ask it to read skills/ppt-master/SKILL.md; for everything else, check the FAQ — it covers model selection, layout issues, export problems, and more. Continuously updated from real user reports.

Two paths for non-user images, mixable per image in the same deck:

A) AI generation — use the agent host's native image tool when available, or image_gen.py with IMAGE_BACKEND plus the provider's *_API_KEY. Host-native generation needs no separate provider image API key; ask the agent to use its own image tool. Run python3 skills/ppt-master/scripts/image_gen.py --list-backends for the configured-provider path. 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:

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.
