Mamadoc

AI-powered document processing for managing household paperwork. Scan letters as PDFs, get structured extraction with actionable recommendations, and track everything in a Streamlit dashboard.

Built for the real-world problem of managing a pile of unsorted letters — insurance notices, invoices, government correspondence, care facility paperwork — where you need to know what each letter says, what you need to do, and which letters belong to the same matter.

What It Does

• Multi-language PDF reading — Claude Vision reads scanned documents in any language (German, Turkish, French, etc.) and produces English summaries
• Structured extraction — sender, date, amount, deadline, urgency, document type, reference numbers
• Actionable recommendations — each document gets specific action items with deadlines
• Issue timeline grouping — automatically groups related documents (original letter → reminder → final notice) so you respond to the latest, not the first one you scanned
• Personal task manager — add your own tasks alongside document-extracted actions
• Conversational Ask tab — ask questions about your documents and tasks in natural language
• File watcher — auto-processes new PDFs dropped into the folder

How It Works

Scanned PDF → Claude Vision API → Structured JSON → SQLite → Streamlit Dashboard

1. Scan a letter as PDF (any scanner, any language)
2. Drop it into the project folder
3. Claude Vision reads the image, extracts structured data, generates English summary + recommendations
4. Documents are automatically grouped into issues by sender + reference number
5. Track action items, mark them done, ask questions about your documents

Requirements

• Python 3.10+
• Poppler (for PDF to image conversion)
• Anthropic API key (~$0.01 per page)

Installing Poppler

Windows: Download from poppler releases, extract, add bin/ to PATH.

macOS: brew install poppler

Linux: sudo apt install poppler-utils

Install

From PyPI

pip install mamadoc

From source

git clone https://github.com/capraCoder/mamadoc.git
cd mamadoc
pip install -e .

Configure

cp .env.example .env
# Edit .env and add your Anthropic API key

Verify setup:

mamadoc check

Usage

CLI commands

# Check environment setup
mamadoc check

# Process all unprocessed PDFs in the project folder
mamadoc process

# Reprocess a specific document
mamadoc process Document_2026-01-15.pdf --force

# Launch the Streamlit dashboard
mamadoc dashboard

# Watch folder for new PDFs and auto-process
mamadoc watch

Direct module execution

python -m mamadoc.process_pdf
python -m mamadoc.process_pdf Document_2026-01-15.pdf --force
python -m streamlit run mamadoc/app.py
python -m mamadoc.watcher

Architecture

mamadoc/
  mamadoc/
    __init__.py     — version
    cli.py          — CLI entry point (mamadoc command)
    config.py       — paths, API keys, logging, constants
    prompt.py       — Claude Vision prompts, JSON parsing, validation
    db.py           — SQLite schema + CRUD (documents, actions, issues, tasks)
    process_pdf.py  — PDF → image → Claude Vision → JSON → DB pipeline
    app.py          — Streamlit dashboard (5 tabs)
    watcher.py      — watchdog auto-processor for new PDFs
  .env              — your API key (not committed)
  mamadoc.db        — SQLite database (auto-created)
  processed/        — extracted JSON + page images
  pyproject.toml    — PyPI package config

Cost

Claude Vision API costs approximately $0.01 per page. A typical single-page letter costs about 1 cent to process. The issue-linking step uses the cheaper Haiku model.

Limitations

• PDFs must be scanned images (not born-digital text PDFs — though those work too)
• Maximum 20 pages per PDF (configurable in config.py)
• Interface is English-only (PDF reading works in any language)
• No multi-user support — single SQLite database, designed for personal use
• Requires internet connection for Claude API calls
