Marketing Claims Analyzer

Instantly analyze marketing claims on any product page.

Marketing Claims Analyzer uses AI to read product pages and evaluate every marketing claim it finds. Each claim gets a clear verdict — Supported, Misleading, or Unverified — with a plain-English explanation and detailed scientific reasoning.

How it works
1. Navigate to any product page (Amazon, Shopify stores, or any website)
2. Click the extension icon
3. Get a full breakdown of every marketing claim on the page

What you get for each claim
- A verdict: Supported, Misleading, or Unverified
- A one-sentence explanation you can understand at a glance
- Detailed reasoning referencing the product's actual ingredients, specs, or components
- Claim category (health, performance, environmental, scientific, and more)

Product-aware analysis
The analyzer first builds an understanding of the product — its type, key ingredients, mechanism of action, and overall marketing tone — before evaluating any claims. This means verdicts are grounded in what the product actually contains, not generic responses.

Works on any product page
- Amazon product listings
- Shopify stores
- Any website with product marketing content

Bring Your Own Key (BYOK)
This extension uses the OpenAI API directly. You provide your own API key, which is stored locally on your device and never sent anywhere except OpenAI. Typical cost: under $0.01 per analysis with GPT-4o Mini.

Your choice of model
- GPT-4o Mini (fast and cheap — recommended)
- GPT-4o (higher quality)
- GPT-4.1 Mini
- GPT-4.1

Smart caching
Results are cached per URL, so reopening the popup on the same page loads instantly without another API call. Hit "Rerun" anytime to get a fresh analysis.

Privacy-first
- No data is collected or sent to any server besides OpenAI
- Your API key stays in local browser storage
- Page content is only sent to OpenAI when you click the extension
- No accounts, no tracking, no analytics
