Pre-screening PK reports
for biotech & CROs.

Three auto-diagnostic engines — Population PK, Tumor Growth and Drug Release — that detect patterns classical exponential models miss. Non-regulated reports, automatic verdict, PDF in your inbox.

How it works
Start with the live samples; request an account when you're ready to upload your own data.
Step 1
Explore the samples

Three engines, three real datasets. Open each PDF to see the verdict, models compared and diagnostic plots — exactly the report a paying client receives.

Step 2
Request access

Tell us your name, company and what you're trying to analyse. We reply within one business day with an upload link and a single-use checkout (€299 per report).

Step 3
Upload & receive

Upload your CSV, get a magic-link to the PDF when the fit completes (typically 5–10 minutes), and a copy in your inbox. No subscription, no commitment.

Live samples — open the PDFs
Each PDF is generated by the same engine that processes paid uploads. Same plots, same verdict logic, same regulatory disclaimer.
What makes FractaLPK different
Built for early-stage screening, when you need a fast answer before opening a full regulatory analysis.
Fractional models

Detect memory effects and long tails that classical exponential models flatten out — common in fractured tablets, heterogeneous tissue and saturating tumour growth.

Multi-model verdict

Up to 8 candidate models fitted in parallel. The engine ranks them and applies an explicit decision rule — no manual model-selection bias.

Automatic diagnostics

Stability check, residuals and "Best fit" badge in every report. If no model wins clearly, the PDF says so — no false-positive verdicts.

Built for screening

Non-regulated, designed to sit before NONMEM / Monolix / PKanalix. Good for biotech early-stage, CROs running internal triage, and academic exploration.
