Frequently asked.

Klaeri is a Chrome extension that automatically scans the ingredients in any product you look at while shopping online — beauty, food, cleaning products, supplements, baby products, and pet food. It shows you what each ingredient is in plain English and tells you which global scientific and regulatory databases have published information about it. We call this "database mentions." We never tell you something is safe or unsafe — we report what scientists have published and let you decide.

Yes — the Chrome extension is free forever. No account required to start scanning. A Klaeri+ plan is coming soon at $4.99/month with features like family allergen profiles, nutrient thresholds, watchlists, and the mobile app. We will never charge for the core ingredient transparency feature.

A few important differences. Some apps use color-coded threat levels like "banned or toxic" — we don't. We believe that kind of labeling is fear-mongering and scientifically imprecise. An ingredient being on a list doesn't mean it's dangerous in every product at every concentration. Klaeri reports facts: "EU SCCS has published findings on this ingredient" — and links directly to the source. You read, you decide. We also reference 12 databases instead of just one or two, and we cover more product categories than most competitors.

Beauty and personal care, food and drinks, cleaning products, supplements and vitamins, baby products, and pet food. If there's an ingredient list, Klaeri can analyze it.

Four ways: (1) Browse mode — just shop normally on Amazon, Sephora, Target, Walmart, iHerb, Ulta, CVS or Walgreens and Klaeri automatically scans every product page. (2) Photo scan — snap a photo of any product and our AI identifies it. (3) Search by name — type any product name. (4) Paste ingredients — copy an ingredient list from anywhere and paste it in. All four methods check the same 12 databases instantly.

When you install Klaeri and visit a supported product page, a Klaeri ingredient bar appears — warm, welcoming, not alarming. It says something like "Klaeri checked 18 ingredients — 4 database mentions found." You tap to expand the full report. It's designed to feel like a knowledgeable friend quietly letting you know what they found, not a warning system screaming at you. You can dismiss it or leave it — it doesn't interrupt your shopping.

Some retailers don't publish full ingredient lists — this is a real problem across the industry. When Klaeri can't find ingredients on a page, it tells you clearly rather than guessing or making something up. You can use the paste mode to manually enter an ingredient list from another source, like the brand's own website or the physical packaging.

Every ingredient shows a colored dot — a red dot means one or more scientific or regulatory bodies have published findings about it. An amber dot means moderate mentions. A green dot means no database mentions found. Tap any ingredient to read a plain-English explanation of what it is, why brands use it, what has been published about it, and who may want to know. Every finding links directly to the original source so you can verify it yourself.

Our team monitors RSS feeds from all 12 sources daily and updates the database when new findings are published. We don't require an app update to push new ingredient data — it refreshes in the background. Klaeri+ users will receive a weekly digest of new findings that match their scan history and watchlists.

Yes. For product lookups we pull from Open Food Facts (4M+ food products), Open Beauty Facts, and Go-UPC as a fallback. These are open, community-maintained databases. When a product is found, we use the ingredient list from these sources and run it through our own 12-database analysis. We don't rely on their ingredient safety ratings — we do our own analysis.

No. A database mention means a scientific or regulatory body has published information about an ingredient — not that it's dangerous. Many well-researched, commonly used ingredients appear in databases simply because they've been studied extensively. The absence of mentions doesn't mean an ingredient is safe, and the presence of mentions doesn't mean it's harmful. Context matters enormously: concentration, formulation, route of exposure, duration, and individual sensitivity all factor in. Klaeri reports what was published — your healthcare provider or a specialist can help you interpret it for your specific situation.

Because we think they're misleading. A score of "8 out of 10 dangerous" implies a level of certainty that doesn't exist in science. Ingredient safety is nuanced — it depends on concentration, how it's used, who's using it, and dozens of other variables. A numerical score flattens all that complexity into a single number that can mislead people into avoiding products that are actually fine for them, or worse, assuming products with low scores are completely safe. We report facts and give you the context to form your own view.

Without an account: Klaeri processes your scans locally and does not store personally identifiable information. With a free account: we store your allergen profile, scan history, and watchlist. We never sell individual user data. Aggregated, anonymous data (product trends, ingredient popularity) may be used for research and business analytics — this is disclosed in our Privacy Policy.

We never sell individual user data. Never. Aggregated anonymous trends (e.g. "the most scanned ingredients this month") may be used commercially, and this is disclosed in our Privacy Policy. Your personal allergen profile, scan history, and health context are private to you.

The Chrome extension, unlimited scans, all 4 scan methods, all 12 databases, plain-English ingredient cards, browse mode on 10+ stores, and basic allergen alerts. Free forever — no account required.

Klaeri+ ($4.99/month, coming soon) adds: 5 family allergen profiles, custom nutrient thresholds (alert when sugar exceeds X grams, etc.), health condition alerts, watchlist with daily monitoring for up to 10 products, weekly ingredient digest, mobile app access (iOS and Android), community access, and side-by-side product comparisons. You can join the waitlist now.

Yes. We partner with brands and retailers who want to embed Klaeri's ingredient transparency engine on their own websites or apps — with white-label options and a plan shaped around your size and volume rather than off-the-shelf pricing. Learn about partnering or start an inquiry.
