YOUR DATA.
YOUR MACHINE.
Load a CSV in the browser, map the evidence columns and calculate repeatable validation metrics without emailing the dataset to Lexium. For a Lexium comparison, only the mapped observation vector is sent through the protected evaluation gateway; ground truth and scoring stay in your browser.
LOAD LOCALLY
Choose a CSV from this computer. The browser parses it in memory; this control does not post the file to a server.

COLUMNS
RESULTS
Map a ground-truth column and a valid estimate method to calculate metrics.
Lower MAE/RMSE only means lower error for the rows and reference column supplied here. It is not a universal model ranking.
EVALUATION ACCESS
The Lexium engine remains server-side. Your ground truth remains in this browser. Before a proprietary run, both sides accept the same evaluation confidentiality boundary.
Customer data remains customer IP; Lexium technology remains Lexium IP. Formal countersigned NDA available for sensitive engagements.
LEXIUM SECURE EVALUATOR
Only the mapped observation vector is sent through the protected Lexium gateway. Ground truth and scoring remain in your browser.
- engine stays server-side
- ground truth stays in the browser
- observation vector only
- version/hash + server-issued receipt returned
THE DATASET STAYS LOCAL.
BROWSER MODE: CSV contents, ground truth and baseline scoring are processed in the browser. LEXIUM SECURE EVALUATION: after invite-only mutual-confidentiality access, only the mapped observation vector and declared noise setting are submitted to the protected Lexium gateway; the proprietary engine remains server-side. EXPORTS: reports and evaluated CSV files are downloaded to your machine unless you choose to share them.
The complete source CSV and ground-truth column are not required by the Lexium engine. For unusually sensitive or regulated datasets, a separately countersigned NDA or on-premises arrangement can be used before evaluation.
VALIDATE WITHOUT HANDING OVER THE DATASET.
The browser validator computes scoring locally. Public Lexium comparisons use a same-origin gateway that forwards only the permitted observation vector to a separately configured server-side engine using server-only credentials. The browser receives estimates plus provenance such as request hash, engine version/hash and an evaluation receipt; it never receives the proprietary executable or source. Internal development can still use the localhost runner.
