Tchekz

What Tchekz Does Tchekz is an automated purchase-verification platform. It connects to a user’s email account, identifies genuine order receipts, extracts structured order data, and verifies whether the items they paid for were delivered correctly. In short: Tchekz checks online orders on the user’s behalf and finds mistakes, missing items, or discrepancies that are otherwise easy to miss. ________________________________________ The Core Problem Tchekz Solves Online shopping generates a high volume of errors: • Missing items • Incorrect quantities • Substituted products • Partial deliveries • Overcharges Retailers and delivery platforms rarely flag these proactively. Users are expected to: • Keep receipts • Manually compare deliveries • Notice discrepancies • Navigate refund processes Most people don’t — so errors go unclaimed. Tchekz automates this entire process. ________________________________________ How Tchekz Works (End-to-End) 1. Secure Email Connection • The user connects their email account (e.g. Gmail). • Tchekz uses read-only access. • No emails are modified, sent, or deleted. ________________________________________ 2. Receipt-Only Detection (Critical Design Choice) Tchekz does not process all emails. It applies a strict receipt-only gate that: • Allows only genuine order receipts • Blocks marketing emails, shipping updates, calendars, promotions, etc. • Prevents unnecessary AI usage and cost • Avoids false positives Only emails that can plausibly be verified as purchases are allowed through. ________________________________________ 3. Order Extraction & Structuring For valid receipts, Tchekz: • Extracts retailer identity • Order number • Items, quantities, and prices • Delivery metadata • Total amounts This data is normalized into a consistent internal format, regardless of retailer (Amazon, Uber Eats, Asda, etc.). ________________________________________ 4. Verification & Analysis Tchekz compares: • What the user paid for vs • What was delivered or fulfilled It identifies: • Missing items • Incorrect quantities • Partial fulfillment • Pricing inconsistencies Each order is marked with a verification status (processed, pending, discrepancy found, etc.). ________________________________________ 5. Persistence, Deduplication & Cost Control Tchekz is designed to: • Never re-process the same receipt twice • Detect duplicates using Gmail message IDs and order numbers • Avoid re-sending previously processed content to AI systems • Only charge for new, verifiable work This prevents: • Double charging • Token waste • User distrust around “overcharging” ________________________________________ 6. User Visibility & Outcomes In the app, users see: • A list of verified orders • Items checked • Discrepancies detected • Potential refunds identified The goal is confidence and transparency, not just data extraction. ________________________________________ What Tchekz Is Not This is important for positioning: • ❌ Not an email scanner • ❌ Not a generic AI inbox reader • ❌ Not a receipt archive • ❌ Not a marketing analytics tool Tchekz is purpose-built for verification — nothing else is allowed through the system. ________________________________________ Why the Architecture Matters Tchekz deliberately enforces: • Strict gating (receipt-only) • Idempotency (no double processing) • Minimal payloads (token & cost control) • Deterministic persistence rules These aren’t accidental — they’re what make the platform: • Trustworthy • Scalable • Cost-efficient • Defensible
