Frequently Asked Questions

What is NirnAI?

NirnAI is an AI-powered shopping and travel assistant that analyzes products and accommodations across 20+ sites, giving you a clear buy/don't-buy recommendation based on ratings, reviews, price fairness, and seller trust.

How does it work?

The Chrome extension automatically activates on supported sites (Amazon, Walmart, Booking.com, Airbnb, etc.). It reads publicly visible product information from the page, sends it to our AI analysis engine, and shows you a verdict — all in seconds.

Which sites are supported?

Shopping: Amazon, Walmart, Target, Costco, Best Buy, Home Depot, Lowe's, eBay, Wayfair, Macy's, Nordstrom, Nike, Apple, Samsung, Dyson, CVS, Walgreens

Travel: Booking.com, Airbnb, Expedia, VRBO, Agoda, Hotels.com, TripAdvisor, Google Travel

Is my data safe?

Yes. We only process publicly visible product data for analysis. We don't collect personal information, browsing history, or passwords. Analysis data is not stored beyond the request. Read our full Privacy Policy.

What do the verdicts mean?

• 🟢 Smart Buy / Book It — High quality, fair price, trusted seller
• 🟡 Think About It — Decent but has some concerns worth considering
• 🔴 Don't Buy / Skip — Significant issues with quality, price, or trust

How does cross-site comparison work?

Search for a destination on nirnai.app and NirnAI scrapes listings from multiple travel platforms (Booking.com, Airbnb, Expedia, etc.), scores them using the same AI engine, and ranks them so you can find the best deal.

Does NirnAI use affiliate links?

Some outbound links on comparison pages include affiliate parameters (e.g., Booking.com via Awin). This helps support NirnAI but does not affect rankings or recommendations. All rankings are determined solely by our scoring algorithm.

The extension isn't showing up on a page

• Make sure you're on a supported site (see list above)
• Make sure you're on a product/listing page, not a search results page
• Try refreshing the page
• Check that the extension is enabled in chrome://extensions

How do I uninstall?

Right-click the NirnAI icon in your browser toolbar and select "Remove from Chrome", or go to chrome://extensions and click Remove.
