Pptagent

We strongly recommend deploying our fine-tuned model for the best experience with our agent project. According to our experiments, it significantly outperforms existing open-source models.

Usage 📖

[!IMPORTANT] Windows is not supported. If you are on Windows, please use WSL.

We strongly recommend starting with the CLI and minimum task to confirm dependencies and environment is configured correctly.

Configuration

If you use the CLI, pptagent onboard can help create and update these configurations interactively. If you use Docker Compose or build from source, you should prepare them manually:

cp deeppresenter/config.yaml.example deeppresenter/config.yaml
cp deeppresenter/mcp.json.example deeppresenter/mcp.json

Optional Services That Improve Quality

The following services can noticeably improve generation quality, especially for research depth, PDF parsing, and visual asset creation:

• Tavily: improves web search quality. Apply for an API key at tavily.com, then set TAVILY_API_KEY in deeppresenter/mcp.json.
• MinerU: improves PDF parsing quality. You can either apply for an API key at mineru.net and set MINERU_API_KEY in deeppresenter/mcp.json, or deploy MinerU locally and set MINERU_API_URL instead.
• Text-to-image model: improves image generation quality. Configure t2i_model in deeppresenter/config.yaml.

If you want a fully offline setup, deploy MinerU locally and set offline_mode: true in deeppresenter/config.yaml to avoid loading network-dependent tools such as web search.

More configurable variables can be found in constants.py.

1. Personal Use / OpenClaw Integration: CLI

[!NOTE] On macOS, the CLI may automatically install several local dependencies, including Homebrew, Node.js, Docker, poppler, Playwright, and llama.cpp.

On Linux, you should prepare the environment by yourself.

Use this mode if you want the fastest local setup or want to plug DeepPresenter into OpenClaw through the CLI.

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# First-time interactive setup
uvx pptagent onboard

# Generate a presentation
uvx pptagent generate "Single Page with Title: Hello World" -o hello.pptx

# Generate with attachments
uvx pptagent generate "Q4 Report" \
  -f data.xlsx \
  -f charts.pdf \
  -p "10-12" \
  -o report.pptx

2. Minimal Setup / Development: Build From Source

Use this mode if you want the smallest abstraction layer and full control over dependencies during development.

uv pip install -e .
playwright install-deps
playwright install chromium
npm install --prefix deeppresenter/html2pptx
modelscope download forceless/fasttext-language-id

docker pull forceless/deeppresenter-sandbox
docker pull forceless/deeppresenter-host
docker tag forceless/deeppresenter-sandbox deeppresenter-sandbox

# or build from dockerfile
docker build -t deeppresenter-sandbox -f deeppresenter/docker/SandBox.Dockerfile .

Start the app:

python webui.py

3. Server Deployment: Docker Compose

Use this mode for a stable server environment with explicit dependencies.

# Pull the public images to avoid build from source
docker pull forceless/deeppresenter-sandbox
docker tag forceless/deeppresenter-sandbox deeppresenter-sandbox

# Or build from source
docker build -t deeppresenter-sandbox -f deeppresenter/docker/SandBox.Dockerfile .

# Start the host service
docker compose up -d

The service exposes the web UI on http://localhost:7861.

    abstract = "Automatically generating presentations from documents is a challenging task that requires accommodating content quality, visual appeal, and structural coherence. Existing methods primarily focus on improving and evaluating the content quality in isolation, overlooking visual appeal and structural coherence, which limits their practical applicability. To address these limitations, we propose PPTAgent, which comprehensively improves presentation generation through a two-stage, edit-based approach inspired by human workflows. PPTAgent first analyzes reference presentations to extract slide-level functional types and content schemas, then drafts an outline and iteratively generates editing actions based on selected reference slides to create new slides. To comprehensively evaluate the quality of generated presentations, we further introduce PPTEval, an evaluation framework that assesses presentations across three dimensions: Content, Design, and Coherence. Results demonstrate that PPTAgent significantly outperforms existing automatic presentation generation methods across all three dimensions."
