Document classification for Routewise
Automatic routing of incoming documents into 24 categories with confidence thresholds. A case study by Arjun Patel, AI Engineer — Chatbots & Document AI.
Challenge
Routewise, a last-mile delivery startup, received 5,000 documents a week by email and upload. A team of four sorted them by hand before any work could begin.
Solution
I trained a lightweight classifier on embeddings with an LLM fallback for ambiguous cases, routed documents automatically above a confidence threshold and sent the rest to a review queue.
