SupportLens AI is a support inbox copilot that helps teams review customer messages, retrieve policy context, draft replies, and keep a human in control before anything reaches the customer.

Step through the support workflow
Inbox home with synced support messages and queue context.
Problem
Support teams jump between inboxes, policies, refund rules, shipping docs, warranty notes, and previous replies. A generic chatbot is not enough because support responses need evidence, privacy controls, and human approval.
What I Built
Support inbox review queue and Gmail OAuth sync
Knowledge upload for policies, FAQs, and product docs
Retrieval workflow for source-backed draft replies
PII redaction, encrypted token storage, and audit logs
Human review before Gmail draft creation
Architecture
The backend uses FastAPI, PostgreSQL, pgvector, encrypted OAuth tokens, audit logging, and protected admin routes. The frontend focuses on a review queue, message detail screen, draft workspace, source review, and privacy state.
Result
The project demonstrates practical AI engineering beyond a chatbot: retrieval, source review, privacy controls, OAuth integration, auditability, and human approval inside a useful business workflow.
