↳ A live system serving real visitors — not a mockup.

A hybrid rule-engine + LLM that auto-classifies and routes a Zoho inbox.

An AI email assistant for Zoho Mail that classifies, routes, and organizes mail with a hybrid rule-engine + LLM pipeline — a deterministic rule engine resolves obvious cases instantly and only ambiguous mail reaches the LLM.

↳ Cuts LLM API cost ~60–70% by resolving obvious cases with the rule engine before involving the LLM.
