What is essential is invisible to the eye.
A pathologist estimates tumor purity by eye. EnsoPurity reads it from the slide — ~2× more accurate than the human eye, against absolute genomic ground truth.

Purity is guessed by eye.
Estimating tumor content from a slide is genuinely hard — and the numbers show it. No fault of the pathologist; the truth is simply invisible to the eye.

EnsoPurity reads it.
Validated against absolute genomic ground truth across 32 cancer types — about double the correlation, half the error.
Draw a region. Read the numbers.
Outline tissue on a real case — purity, nuclei, and DNA yield per region. The unseen, made tangible.
Better in every indication.
Pathologist (amber) → EnsoPurity (teal). The gap is the product — grouped the way a pathologist reads, by organ system.
What the numbers mean
Held-out TCGA + CPTAC slides with paired genomic purity — every indication shown, including the weaker ones. Ground truth is matched sequencing, not another reader's opinion. EnsoCellularity is built and tested too; held back until its validation set is final.
