THE SPREAD

The field, in three measurements.

Where each one sits against LeanCTX, what it costs, and how much of what it says we have been able to check. Three separate measurements — none of them added together into a score.

LEFT TO RIGHT

How alike the wording is

Cosine distance between the two descriptions. It says two products describe themselves the same way. It does not say one replaces the other.

FRONT TO BACK

What it costs

The pricing model off the product’s own pages. Free at the front, paid at the back. No number, because most pricing pages give none.

PILLAR HEIGHT

What stood up

Claims we read off the site and checked. A flat pin is a product we have not been able to verify anything about yet.

The 14 closest are plotted; the list below carries all 24.

EVERY ALTERNATIVE

24 products, closest wording first.

Ordered by how similarly each one describes itself to LeanCTX. That is a fact about wording, not a verdict about fit.
