What is Chomp?

Chomp checks the ingredients in hundreds of thousands of foods, so you can tell at a glance whether a product fits your diet — vegan, vegetarian, gluten-free, or just the ingredients you want to avoid.

Why we built it

Chomp started when @peter and his wife @molly went vegan and ran into the same problem everyone does: ingredient labels don't answer the question you're actually asking. Plenty of products look vegan and aren't, and plenty of ingredients — caramel, sugar, natural flavors — can come from either plants or animals depending on who made them.

Peter built Chomp so anyone could look up a product and get a straight answer, with the reasoning shown.

How it works

Search for a product or brand, or scan a barcode with the app in the store. We read the full ingredient list and check every ingredient against our database of 650+ ingredients that can break a vegan, vegetarian, or gluten-free diet. If something doesn't fit, we flag it and tell you why, in plain language. Ingredients that can go either way get an honest "maybe" instead of a false yes.

With a free account, Chomp grades everything against your diet automatically. You can also add your own ingredients to avoid, save products to lists, and write reviews that help the next person.
