Verify the claim

Certification Checker

The Certification Checker searches any brand in our directory and returns a verified yes or no on the certifications that matter, including GOTS, OEKO-TEX, B Corp and 1% for the Planet. Every result links straight to the official register, so you can confirm each certification at its original source.

Claim Checker

The Claim Checker reads any sustainability line you paste and flags the vague, unprovable words that brands hide behind. It then checks the certifications named in that claim against the real records and tells you whether the wording actually holds up.

Cert Decoder

The Cert Decoder explains in plain language what each certification genuinely guarantees, from organic fibre to fair worker pay. It is equally clear about what that certification leaves out, so you always know the exact limits of the label.

Decode a product

Label Decoder

The Label Decoder reads any garment composition you paste and calculates the true natural fibre percentage. It returns a clear fibre breakdown, a microplastic shed rating and a jargon glossary that translates every material listed on the label.

Microplastic Shed-Risk

The Microplastic Shed-Risk tool estimates how much plastic a fabric sheds into your wash water and out into the wider environment. It then gives you a simple wash routine that reduces that shedding from the clothes you already own.

Will It Last

The Will It Last tool estimates how many wears a garment will survive, based on its fibre, weight and price. It converts that lifespan into a true cost per wear, so you can see whether a cheaper piece is really the more expensive choice.

Label-Trust Indicator

The Label-Trust Indicator shows how often a stated fibre and origin, such as a "100% cotton" tag, turns out to be misstated. It gives that claim a clear trust rating, so you know exactly when a label deserves a second look.
