-# Document Management System
+# Document Processor
 
-Automated document processing pipeline for scanning, OCR, classification, and indexing.
+AI-powered document management system using Claude vision for extraction and SQLite for storage/search.
 
-## Architecture
+## Features
+
+- **AI Vision Analysis**: Uses Claude to read documents, extract text, classify, and summarize
+- **No OCR dependencies**: Just drop files in inbox, AI handles the rest
+- **SQLite Storage**: Full-text search via SQLite, embeddings ready (placeholder)
+- **Auto-categorization**: Taxes, bills, medical, insurance, legal, financial, etc.
+- **Expense Tracking**: Auto-exports bills/receipts to CSV
+
+## Setup
+
+```bash
+cd ~/dev/doc-processor
+
+# Create/activate venv
+python3 -m venv venv
+source venv/bin/activate
+
+# Install dependencies
+pip install anthropic
+
+# Configure API key (one of these methods):
+# Option 1: Environment variable
+export ANTHROPIC_API_KEY=sk-ant-...
+
+# Option 2: .env file
+echo 'ANTHROPIC_API_KEY=sk-ant-...' > .env
+```
+
+## Usage
+
+```bash
+# Activate venv first
+source ~/dev/doc-processor/venv/bin/activate
+
+# Process all documents in inbox
+python processor.py
+
+# Watch inbox continuously
+python processor.py --watch
+
+# Process single file
+python processor.py --file /path/to/document.pdf
+
+# Search documents
+python search.py "query"
+python search.py -c medical              # By category
+python search.py -t receipt              # By type
+python search.py -s abc123               # Show full document
+python search.py --stats                 # Statistics
+python search.py -l                      # List all
+```
+

 ```
 
-## How It Works
+## Supported Formats
 
-1. **Drop a document** in `~/documents/inbox/` (via SMB, phone scan, or manually)
+- PDF (converted to image for vision)
-2. **Daemon processes it** (runs every 60 seconds):
+- Images: PNG, JPG, JPEG, GIF, WebP, TIFF, BMP
-   - Extracts text (pdftotext or tesseract OCR)
-   - Classifies document type and category
-   - Extracts key fields (date, vendor, amount)
-   - Stores original file by content hash
-   - Creates markdown record
-   - Updates searchable index
-   - Exports expenses to CSV
-3. **Search** your documents anytime
-
-## Commands
-
-```bash
-# Process inbox manually
-python3 ~/dev/doc-processor/processor.py
-
-# Process single file
-python3 ~/dev/doc-processor/processor.py --file /path/to/doc.pdf
-
-# Watch mode (manual, daemon does this automatically)
-python3 ~/dev/doc-processor/processor.py --watch --interval 30
-
-# Search documents
-python3 ~/dev/doc-processor/search.py "duke energy"
-python3 ~/dev/doc-processor/search.py -c bills        # By category
-python3 ~/dev/doc-processor/search.py -t receipt      # By type
-python3 ~/dev/doc-processor/search.py --stats         # Statistics
-python3 ~/dev/doc-processor/search.py -l              # List all
-python3 ~/dev/doc-processor/search.py -s <doc_id>     # Show full record
-```
-
-## Daemon
-
-```bash
-# Status
-systemctl --user status doc-processor
-
-# Restart
-systemctl --user restart doc-processor
-
-# Logs
-journalctl --user -u doc-processor -f
-```
-
-## Scanner Setup
-
-1. Get a scanner with SMB support (Brother ADS-1700W, Fujitsu ScanSnap, etc.)
-2. Configure scanner to save to SMB share: `\\192.168.1.16\documents\inbox\`
-3. Feed paper, press scan
-4. Documents auto-process within 60 seconds
 
 ## Categories
 
-| Category | Documents |
+- taxes, bills, medical, insurance, legal
-|----------|-----------|
+- financial, expenses, vehicles, home
-| taxes | W-2, 1099, tax returns, IRS forms |
+- personal, contacts, uncategorized
-| bills | Utility bills, invoices |
-| medical | Medical records, prescriptions |
-| insurance | Policies, claims |
-| legal | Contracts, agreements |
-| financial | Bank statements, investments |
-| expenses | Receipts, purchases |
-| vehicles | Registration, maintenance |
-| home | Mortgage, HOA, property |
-| personal | General documents |
-| contacts | Business cards |
-| uncategorized | Unclassified |
 
-## SMB Share Setup
+## Systemd Service
 
-Already configured on james server:
+```bash
-```
+# Install service
-[documents]
+systemctl --user daemon-reload
-   path = /home/johan/documents
+systemctl --user enable doc-processor
-   browsable = yes
+systemctl --user start doc-processor
-   writable = yes
+
-   valid users = scanner, johan
+# Check status
+systemctl --user status doc-processor
+journalctl --user -u doc-processor -f
 ```
 
-Scanner user can write to inbox, processed files go to other directories.
+## Requirements
+
+- Python 3.10+
+- `anthropic` Python package
+- `pdftoppm` (poppler-utils) for PDF conversion
+- Anthropic API key
+
+## API Key
+
+The processor looks for the API key in this order:
+1. `ANTHROPIC_API_KEY` environment variable
+2. `~/dev/doc-processor/.env` file
+
+## Embeddings
+
+The embedding storage is ready but the generation is a placeholder. Options:
+- OpenAI text-embedding-3-small (cheap, good)
+- Voyage AI (optimized for documents)
+- Local sentence-transformers
+
+Currently uses SQLite full-text search which works well for most use cases.
