Frequently Asked Questions

A free browser extension for Chrome and Firefox that tells you whether what's on a page is vegan. On a product page it gives a verdict for the product and lists its ingredients or materials, with the animal-derived ones highlighted. For cosmetics and household items it also says whether the product is cruelty-free. On a restaurant's website, a PDF menu or a Google Maps place page, it marks which dishes are vegan.

Because it's easy to buy something non-vegan by accident, especially when you don't think to check. Nobody reads the ingredients of every loaf of bread, bag of crisps or bar of dark chocolate, because surely those are vegan. Yet many contain milk, eggs, whey or butterfat. Those are exactly the products that slip through.

Even when you do check, it's tedious. Ingredient lists are long, hidden behind tabs, or missing. Additives like carmine, shellac or casein don't sound like animal products. Clothing listings bury the materials. Restaurant menus rarely label vegan dishes at all.

Vegan Confirmed does that first pass of reading for you, including on the products you wouldn't have thought to check, so you can spend your attention on the cases that actually need it.

Install it, open any product page or restaurant menu, click the extension icon and press Analyze this page. On shopping sites it also checks automatically when you click "Add to cart" (see below).

Chrome and Firefox on desktop. It works on most online shops and restaurant websites, including menus published as PDFs, and on Google Maps place pages. Safari and mobile browsers aren't supported yet.

No. It's usually right, but it isn't guaranteed to be, and you shouldn't trust it blindly. Mistakes can happen because:

• The page itself is incomplete or wrong, for example a missing ingredient list.
• Some ingredients, such as "natural flavors", sugar or vitamin D3, can come from either plants or animals, and the page doesn't say which.
• Recipes and suppliers change, and shop listings aren't always updated.
• The analysis is done by AI, which can misread a page or be confidently wrong.

When the answer matters, check the label, the manufacturer's site, or ask the restaurant.

No. "Vegan" is not the same as "free of milk or egg allergens". Vegan products can still be made on shared equipment, and the extension can make mistakes. If you have an allergy, always read the packaging and talk to the restaurant directly.

Please tell us! Use the 👍/👎 buttons under the answer in the extension and add a short comment, or open an issue on GitHub. Wrong answers are the most useful feedback we get.

Because that's the last easy moment to catch a mistake. Most people don't check every product before deciding to buy it, and it's easy to miss a non-vegan ingredient in a hurry. When you click "Add to cart", the extension checks the product in the background and, if it finds something non-vegan, shows a notification and a red badge on its icon.

If the product looks vegan, it stays quiet. It never blocks or changes your purchase; the alert is only there so you don't find out after the order arrives.

Yes. When you analyze a page, its text is sent to our server, where a large language model reads it and decides what kind of page it is, which ingredients or materials are listed, and whether they're vegan.

AI is what lets it handle messy, inconsistent pages that a simple keyword list couldn't. It's also why it can occasionally be wrong - see Is it always accurate?

The extension only sends a page when you ask it to analyze one, or when you click "Add to cart". It sends the page's text, title and address, and nothing else: not your browsing history, and there are no accounts or sign-ups. Results are cached in your browser for 24 hours so the same page isn't analyzed twice.

We keep a record of analyses on our server to find and fix wrong answers. We don't sell or share it. See the privacy policy for details.

No. Vegan Confirmed is free, with no ads, no subscriptions, no paid tiers and no affiliate links. It's a personal project, and the running costs are paid out of pocket.

Yes, the extension is MIT-licensed and its code is on GitHub.

Vegan Confirmed is built by Anton, a software engineer who has been vegan since 2016. He works on it in his spare time.
