namingpaper 0.1.8

CLI tool to rename academic papers using AI-extracted metadata

namingpaper

A CLI tool that renames academic PDF papers using AI-extracted metadata.

Before: 1-s2.0-S0304405X13000044-main.pdf

After: Fama and French, (1993, JFE), Common risk factors in the returns....pdf

Features

• Extracts metadata (authors, year, journal, title) from PDFs using AI
• Supports multiple AI providers: Claude, OpenAI, Gemini, and Ollama (local)
• Batch processing - rename entire directories at once
• Custom templates - flexible filename formatting
• Dry-run mode by default for safety
• Copy to output directory (keeps original file)
• Handles filename collisions (skip, increment, or overwrite)
• Common journal abbreviations (JFE, AER, QJE, etc.)

Installation

# Using uv (recommended)
uv tool install namingpaper

# Using pipx
pipx install namingpaper

# With optional providers
uv tool install "namingpaper[openai]"    # OpenAI support
uv tool install "namingpaper[gemini]"    # Gemini support
# or with pipx
pipx install "namingpaper[openai]"
pipx install "namingpaper[gemini]"

# Update to latest version
uv tool upgrade namingpaper
# or
pipx upgrade namingpaper

# Or install from source
git clone https://github.com/DanTsai0903/namingpaper.git
cd namingpaper
uv sync

Quick Start

The default provider is Ollama (local, no API key needed). Install it from ollama.com, then pull the required model:

ollama pull llama3.1:8b

# Preview the rename (dry run)
namingpaper rename paper.pdf

# Actually rename the file
namingpaper rename paper.pdf --execute

# Batch rename all PDFs in a directory
namingpaper batch ~/Downloads/papers --execute

Using Cloud Providers

If you want to use Claude, OpenAI, or Gemini instead of local Ollama:

# Option 1: Set environment variable (temporary, current session only)
export NAMINGPAPER_ANTHROPIC_API_KEY=sk-ant-api03-xxxxx
namingpaper rename paper.pdf -p claude

# Option 2: Add to shell profile (permanent)
# For zsh (macOS default):
echo 'export NAMINGPAPER_ANTHROPIC_API_KEY=sk-ant-api03-xxxxx' >> ~/.zshrc
source ~/.zshrc

# For bash:
echo 'export NAMINGPAPER_ANTHROPIC_API_KEY=sk-ant-api03-xxxxx' >> ~/.bashrc
source ~/.bashrc

# Option 3: Use config file (~/.namingpaper/config.toml)
mkdir -p ~/.namingpaper
cat > ~/.namingpaper/config.toml << EOF
ai_provider = "claude"
anthropic_api_key = "sk-ant-api03-xxxxx"
EOF

Examples

Single File

# Dry run with Ollama (default)

Batch Processing

# Preview all renames in a directory
namingpaper batch ~/Downloads/papers

# Execute batch rename
namingpaper batch ~/Downloads/papers --execute

# Recursive scan with subdirectories
namingpaper batch ~/Downloads/papers -r --execute

# Filter by pattern (only 2023 papers)
namingpaper batch ~/Downloads/papers -f "2023*" --execute

# Use compact template
namingpaper batch ~/Downloads/papers -t compact --execute

# Custom template
namingpaper batch ~/Downloads/papers -t "{year} - {authors} - {title}" --execute

# Copy to organized folder

AI Providers

Ollama (Default)

Local LLM, no API key needed. Just have Ollama running. Text is extracted from PDFs using PyMuPDF; the OCR model is only used as a fallback for scanned/image-only PDFs.

# Pull the required model
ollama pull llama3.1:8b        # Text model (parses metadata)

# Optional: OCR fallback for scanned PDFs
ollama pull deepseek-ocr

# Use it (default provider)
namingpaper rename paper.pdf

# Use a different text model
namingpaper rename paper.pdf -m gemma2:9b

# Use a different OCR model (for scanned PDFs)
namingpaper rename paper.pdf --ocr-model llava

Claude

export NAMINGPAPER_ANTHROPIC_API_KEY=sk-ant-...
namingpaper rename paper.pdf -p claude

# Use a specific Claude model
namingpaper rename paper.pdf -p claude -m claude-haiku-4-20250514

OpenAI

uv add "namingpaper[openai]"
export NAMINGPAPER_OPENAI_API_KEY=sk-...
namingpaper rename paper.pdf -p openai

# Use a specific OpenAI model
namingpaper rename paper.pdf -p openai -m gpt-4o-mini

Gemini

export NAMINGPAPER_GEMINI_API_KEY=...
namingpaper rename paper.pdf -p gemini

# Use a specific Gemini model
