01
Data
Import CSV, Excel, or SPSS. Review cleaning and preview before you model.
SEMSTUDIO
Structural equation modeling, end to end.
From survey data to measurement, paths, and publication-ready reports — PLS, PLSc, and CB-SEM in the browser.
Workflow
Four steps from file to findings
The same flow as the live product: Data → Model → Analyze → Results.
02
Model
Apply a research preset or define constructs and paths on the canvas.
03
Analyze & results
Run PLS / PLSc / CB-SEM, advanced tools, assessment checklist, then export.

FAQ
Straight answers for researchers and labs.
Where do I run the analysis?
In the workspace. This site introduces the product; modeling and SEM tools live there and are fully available.
What files can I upload?
CSV, Excel (.xlsx / .xls), and SPSS (.sav). Samples: sample datasets.
Is billing live?
Not yet. Pricing here is for launch planning. The workspace currently offers the full feature set.
Where is the user guide?
How do color thresholds work?
Results mark pass / warn / fail using common SEM rules of thumb (loadings, AVE, HTMT, VIF, and related). Interpret them with your design in mind.
Documentation
Guide preview
A short path through the workspace. Full detail is in the user guide.
Typical workflow
- Upload CSV / Excel / SPSS and review the cleaning report.
- Apply a sample preset or define constructs and paths.
- Run PLS-SEM (or PLSc / CB-SEM).
- Check measurement, then structural paths.
- Bootstrap, then mediation if you need indirect effects.
- Optional: IPMA, MGA, sample size, Q² / PLSpredict.
- Export HTML or Word.
