Structural comparison · Gromov-Wasserstein

Find the tangentbetween any two datasets.

Datangent compares the hidden structure of any two tables, no shared columns, no shared units, no assumptions, and tells you honestly whether the connection is real. Open the app Private beta · bring two clean numeric CSVs · verdicts in the form p = 0.0020, or an honest refusal.
Exact Gromov-Wasserstein, computed in full, never an approximation.
Every verdict stress-tested against 10,000 matched look-alikes.
Every row counts. No subsampling, no silent caps.
Dirty data gets a plain-language refusal, never a fake answer.
How it works

Three steps, one honest verdict.

01

Open your data

Point Datangent at a folder. Your files open in a real editor, table view or source view, and stay in your browser until you run.

02

Pick A and B

Any two numeric tables. Different rows, different columns, different worlds. Only the structure inside each table is compared.

p = 0.0020 SIGNIFICANCE-TESTED VERDICT
03

Read the verdict

A significance test decides, and the map shows which rows line up. Candidates to investigate, never proof.

The instrument

A workbench, not a wizard.

Two tables. One honest answer.

Open the workspace, load two CSVs, and see where they touch.
