Chronological Inference Engine · Windows beta

Explore the past.
Model processes.
Account for uncertainty.

Radiocarbon calibration and Bayesian chronological modelling, without scripting. Bring your dates together, make your assumptions explicit, and explore when events happened and the processes that shaped them.

A workspace for archaeological time

Calibrate · Model · Inspect

Chronologer calibration workspace showing radiocarbon determinations, calibrated date distributions, and the IntCal20 curve. — Radiocarbon calibration with uncertainty and curve overlays. An example from the application.

01 / Calibrate

Start with your evidence

Import radiocarbon dates from CSV or enter them directly. Compare individual and stacked calibrations using IntCal20.

02 / Model

Ask about events through time

Fit single-density and mixture models, or estimate event intensity with a Gaussian-process point-process model.

03 / Inspect

Keep the reasoning visible

Review MCMC diagnostics, export figures, and save inputs and results together in a portable project.

Try it with your dates

Download. Unzip. Open.

Run ChronoApp.exe inside the extracted folder. The local application opens in your browser. Example CSVs are included in docs/examples/.

A first public beta

Inspect results critically and check MCMC diagnostics before scientific use.

Report a problem

No data entry needed

Try it with example dates

The Windows ZIP includes made-up test datasets in ChronoApp/docs/examples/. Start with 20 example dates, or explore mixture modelling with 60 dates in three groups.

Choose Project → Import CSV in the app and select a file. These are synthetic examples, not archaeological observations. The example guide gives suggested model settings.
