KnowVault focuses on defect-first review analysis for e-commerce: instead of generic sentiment scores, every report ranks the top physical/quality defect themes by frequency, cross-references them with order timelines, and preserves verbatim buyer language so sellers can hear complaints exactly as customers phrased them. Reports are one-off purchases — no subscription required.
Three reasons: (1) Speed — paste an Amazon URL and get a structured report in minutes, no data pipeline setup; (2) Depth — beyond sentiment, we surface defect rankings, expectation gaps, and buyer-language themes that generic review tools flatten into star averages; (3) Pricing — buy a single report when you need it, or a credit pack for regular audits, instead of paying a monthly seat fee for features you rarely use.
Amazon FBA sellers and e-commerce brand owners who source products and need to validate quality before stocking, track defect trends after batch changes, and audit competitor listings. Also agencies that manage catalogs for multiple seller clients.
KnowVault started as an internal tool: our team was validating supplier samples and kept drowning in thousands of raw reviews per product. Spreadsheets and sentiment scores kept missing the real signal — recurring physical defects buried in 3-star reviews. We built the analysis pipeline we wished existed, and turned it into a product.
LLM-powered analysis pipeline (large language models for theme extraction and buyer-language clustering), a scalable review-fetching layer, Next.js for the web app, and a Python/FastAPI backend.
