Second Opinion adds one button to Amazon product pages. It reads the public product information on the page you are viewing (title, price, list price, brand, rating, rating count, star distribution, badges, seller, Amazon's review summary and visible review excerpts) and sends it to our server so an AI model can produce an independent opinion of that product. For some users this check runs automatically shortly after a product page loads.
No browsing history, no pages other than the Amazon product page you are on, no Amazon account data, no personal information beyond what is described above. The extension does not run on any site other than the Amazon storefronts listed in its permissions.
Product page content is sent to Anthropic's API to generate the opinion, under Anthropic's commercial terms, which do not permit training on that data. Payment data is processed by Stripe. We do not sell data and we do not share it with anyone else.
Check logs are kept for up to 24 months. To delete everything tied to your install id, or to cancel a subscription, email [email protected]. Uninstalling the extension removes the install id from your browser.
