Markdown to PDF Converter (llmmd2pdf)

A local Python application built with Shiny for Python that allows you to paste Markdown text, preprocess it, and convert it to PDF using Quarto.

Currently, markdown input needs to be generated by other programs, such as SaveYourChat or manual copy-pasting from LLM chat windows (e.g., ChatGPT, Gemini, Claude).

Features

• GUI Interface: Clean Shiny layout for text input and settings.
• Smart Preprocessing: Cleans "Gemini Apps Activity" footers, removes profile placeholders, and cleans artifact tags.
• Native Directory Picker: Robustly handles native macOS file dialogs via a subprocess.
• Quarto Integration: High-quality PDF conversion.
• Metadata & Config: Autosaves your favorite models, author name, and stores them in the standard OS configuration path.

Prerequisites

1. Python 3.9+
2. Quarto CLI: Required for PDF generation.
   • Download Quarto
   • Verify: quarto --version

Option 1: Installation via PyPI (Recommended)

This is the easiest way to use the tool.

1. Install the package:
   pip install llmmd2pdf

2. Run the app:
   llmmd2pdf

   The app will open in your browser automatically.

Option 2: Installation from Source (GitHub)

Use this if you want to modify the code or contribute.

1. Clone the repository:
   git clone [https://github.com/yourusername/llmmd2pdf.git\](https://github.com/yourusername/llmmd2pdf.git)
   cd llmmd2pdf

2. Install in editable mode:
   pip install -e .

3. Run the app:
   llmmd2pdf

Configuration

The application stores settings in the standard Application Support folder for your OS.

• macOS: ~/Library/Application Support/llmmd2pdf/config.toml
• Windows: %APPDATA%/llmmd2pdf/config.toml
• Linux: ~/.config/llmmd2pdf/config.toml

This file is automatically created when you run the app. You can modify it to set default models, your name, or the server port.

Default Config:
models = [ "Claude Haiku 4.5", "Claude Opus 4.5", "Claude Sonnet 4.5", "GPT-4o", "GPT-4o mini", "GPT-5", "GPT-5.1", "Gemini 3 Pro"]
author = "Karl Dafoe"
port = 5555 # Change this to run on a different port

Changing the Port

You can change the port by editing the port value in the config file above. The next time you run llmmd2pdf, it will bind to that port.

Roadmap

• Add unit tests for preprocessing functions
• maybe add API-based direct fetching of conversations
• Improve Quarto template customization options
