About KnowVault

What we do

KnowVault is an AI-powered review analysis service for e-commerce sellers. Upload a CSV of your product reviews (Amazon, Shopify, app stores, survey exports) and get a developer-grade report in about 20 seconds: theme clusters, sentiment breakdown, risk alerts, competitive insights, and a prioritized list of what to fix first.

We also build a set of free, browser-based tools — a review CSV analyzer, a star-rating benchmark, review summarizers, an NPS calculator, and step-by-step export guides — so you can start understanding your feedback before you pay for anything.

How we work

• Analysis you can act on. We focus on negative themes, how often they repeat, and real customer quotes — not generic star-rating dashboards.
• Free tools run in your browser. Data you paste into our free tools is processed client-side and never uploaded to our servers.
• Honest sourcing. Our guides cite official documentation (Amazon Seller Central help pages, platform APIs) and say so when a menu or column name can vary.

Pricing, in one paragraph

During the beta period, full analysis reports are free. After beta, you can buy a one-time report (from $19.90 for a Single-Platform Report — no subscription) or subscribe to continuous monitoring from $19/month. The free tools stay free. See pricing for details.

Where your data lives

Account data and uploaded files are stored on servers located in Hong Kong, with automatic daily database backups. We do not sell your data and do not share it with third parties, except infrastructure providers strictly necessary to operate the service. Full details are in our Privacy Policy.
