Register and steward a portfolio without assessing each substance by hand.

When you steward hundreds of substances, the manual approach breaks: you cannot assess each one at the depth regulators expect, track which endpoints each tonnage band requires, and keep up as guidance shifts underneath you.

ToxIndex handles the gathering and prediction across the whole portfolio, knows the data requirements per tonnage band, and flags which existing assessments a guidance change touches, so stewardship becomes maintenance, not re-litigation.
