Catch website contradictions before
your customers do.
An automated web audit engine that crawls your public pages and compares your website strictly against itself. Detect conflicting pricing, expired promotions, mismatched policies, and broken claim integrity — with dual verbatim DOM quotations and zero AI hallucinations.
Zero Hallucinations. Only Verbatim Evidence.
Most AI auditing tools hallucinate issues that don't exist. OpenSiteCheck Consistency guarantees 100% factual accuracy by requiring two exact, retained DOM quotations before any conflict is surfaced.
Conflicting Free Shipping Minimums
The crawler extracted two contradictory dollar thresholds across marketing landing pages and checkout policies, anchored with dual exact DOM quotations and cryptographic element hashes.
Every finding includes direct CSS selectors, surrounding context, and SHA-256 verified text matches.
"Enjoy Fast, Free Standard Shipping on All Domestic Orders Over $50."
header > div.banner > span.promo-text
"Free ground delivery applies automatically to qualifying orders totaling $75 or more before tax."
main > article > section#terms > p:nth-child(3)
Update homepage hero copy or shipping policy table to match. Conflicting thresholds cause checkout abandonments, chargebacks, and customer support disputes.
What the Consistency Engine Audits
Websites evolve over years across different team members. As copy is added to new landing pages, older pages frequently retain stale, conflicting, or legally risky commitments.
Pricing & Shipping Thresholds
Identifies different prices advertised for the same service tier, divergent free shipping minimums, or hidden addon fees mentioned on one page but omitted on checkout.
Expired Offers & Coupon Codes
Deterministically discovers promotional banners with past expiration dates, expired seasonal discounts (e.g. "Black Friday 2024"), and dead promotional codes.
Business Hours, Phone & NAP
Verifies that operating hours, emergency hotline numbers, physical suite addresses, and contact emails match perfectly across header bars, contact pages, and footers.
Guarantees & Return Policies
Catches mismatches between marketing claims ("100% 60-day money-back guarantee") and legal policy pages ("Returns accepted within 14 days subject to restocking fee").
JSON-LD Schema vs. Rendered Copy
Cross-references machine-readable structured schema against visible page text to prevent Google penalties for misleading pricing, fake review counts, or mismatched author markup.
Feature & Plan Specifications
Checks feature comparison matrices against product checkout pages to ensure storage quotas, seat limits, and support tier commitments align across all public marketing assets.
Engine Technical Specifications
Built specifically for developers and business operators who value privacy, precision, and deterministic execution over vague algorithmic scores.

From Public Pages to Deterministic Proof
How our Chromium engine performs out-of-band cross-matching in 3 clear stages.
Isolated Crawl & DOM Ingestion
Playwright Chromium fetches public pages, handles clientside rendering, strips boilerplate navigation, and extracts visible marketing claims with precise CSS selectors.
Self-Referential Claim Gate
Extracted statements are indexed and cross-evaluated across 10 consistency vectors. Conflicting numbers, dates, terms, or policies are flagged only when two verbatim passages clash.
Standalone Evidence Report
Generate an offline HTML and JSON artifact containing side-by-side quotation diffs, SHA-256 integrity tokens, and plain-English reconciliation recommendations for content editors.
