Score a formula.

Paste the ingredient list from any label, most concentrated first. We match each line to our database and return the product’s Natural Origin Index — the mass fraction that came from a renewable feedstock.

Percentages are optional. Give one for every line and we use them exactly; leave them out and we estimate from label order.

Your formula is never stored — it is scored in memory and discarded, and the PDF is built in your browser. For a figure you can defend to a retailer or a regulator, get a verified report, or read how the NOI is calculated.
