The problem

Shopping vegan and cruelty-free shouldn't require detective work.

A label says "cruelty-free." A certification logo means one thing on one product and something else on the next. The parent company tells a different story than the packaging. So you open twelve tabs, and twenty minutes later, you still don't know.

"

Labels are vague on purpose. "Cruelty-free" has no legal definition. It can mean the finished product wasn't tested — while the ingredients were.

"

Certifications don't tell the whole story. A logo covers the brand you see — not always the parent company that owns it, or the markets where the rules differ.

"

Real research takes real time. Ingredient names, sourcing pages, forum threads, three-year-old brand statements — verifying one product properly can take longer than the shopping trip itself.

How NTDF Lens works

Three steps. No spreadsheets required.

1

Scan automatically

Browse Amazon like you normally would. Lens reads the product page and starts working the moment you land on it.

2

Lens gathers the evidence

Ingredient lists, certifications, parent company records, testing policies — pulled from real sources, not vibes.

3

Get a clear result

A plain-language verdict on vegan and cruelty-free status, plus exactly how confident Lens is in it.

What makes Lens different

NTDF Lens isn't "AI that says yes or no." It's evidence, with an honest confidence level.

Googling a product gets you opinions, outdated blog posts, and brands marking their own homework. Lens instead grades what it actually found — and tells you when the answer just isn't clear yet.

High confidenceStrong evidence supports the claim, such as a verified ingredient list, trusted certification, or reliable product documentation.
Medium confidenceGood evidence supports the claim, but some uncertainty remains. For example, an ingredient source still needs verification, or the evidence comes from a brand-wide policy.
Low confidenceThere's some evidence, but it's limited, weak, or conflicting.
Unable to verifyWe couldn't find enough reliable evidence to confirm or refute the claim. That's a gap, not a guess.

When the answer is just no

Sometimes a product fails outright — a confirmed animal-derived ingredient, a parent company with an active testing policy. Lens doesn't call that "low confidence." It calls it what it is.

Not vegan   Not cruelty free

Uncertainty and a known "no" look nothing alike in Lens — on purpose.

Transparency

No black boxes. No pretending we know what we don't know.

Every result Lens gives you can be traced back through the same process — the same one, every time, for every product.

If the evidence is strong, Lens says so. If it's thin, Lens says that too. It's designed to be honest about the quality of the information available, not to manufacture confidence that isn't there.
