Most expense trackers require manual input — SpendLens eliminates that entirely. Point your camera at any receipt and the system extracts line items, totals, tax, and merchant data using a Gemini Vision OCR pipeline with custom post-processing to handle crumpled receipts, faded ink, and non-standard formats. Built an expense categorization engine that learns from user corrections over time. The analytics dashboard surfaces spending patterns, category breakdowns, and anomaly detection across custom date ranges with server-side aggregation for fast queries on large datasets.
