InvoiceAssistant
An AI invoicing workflow that turns natural speech and historical documents into structured, editable invoices.
Outcome
Speech-to-text, retrieval, extraction, and PDF generation in one workflow.
The system combines a FastAPI backend, speech transcription, semantic retrieval over prior invoices, resilient PDF extraction, and a responsive editing surface. The result is a practical AI feature chain—not a chatbot attached to a form.
Engineering signals
- RAG over prior invoices
- Structured PDF extraction
- Local vector lifecycle management
