# Mistral AI Invoice Reconciliation for Stripe
 
Automatically extracts structured data from PDF invoices and reconciles them against Stripe transactions, flagging discrepancies for your finance team.
 
## Architecture
 
```
PDF Upload → unpdf/tesseract OCR → Confidence Router classification
    → Mistral LLM extraction → jsonrepair validation
    → Stripe reconciliation → Discrepancy report email
```
 
## Setup
 
1. Copy `.env.example` to `.env` and fill in values.
2. Run `pnpm install`.
3. Run `pnpm typecheck` and `pnpm lint`.
4. Start the server with `node dist/server.js` after building, or use `tsx src/server.ts`.
