Desktop statistical analysis

Statistical analysis, done properly.

Everything you need for real analysis

One application, five ways to reach the same catalog: the GUI, an editable syntax console, the AI assistant, an MCP server for external agents, and a headless batch runner.

Data editor

A fast, Excel-like sheet with a Variable View for metadata, value labels, missing-value handling, and self-documenting column tooltips.

A broad Analyze program

Descriptives, regression, GLM and mixed models, survival and time series, multivariate methods, Bayesian tests and more — 87 analysis tools in one catalog.

Graphs

Histograms, scatterplots, boxplots and a unified Chart Builder, painted straight into the output viewer.

AI assistant

A provider-neutral agent — Claude, or any OpenAI-compatible backend, including a local Ollama — that runs analyses in plain language and renders results inline.

Reproducibility

Every GUI action emits an editable, re-runnable command. Export output to HTML, Markdown or LaTeX, or as a Python script.

Native performance

A native Rust engine — an in-house columnar store with Parquet I/O over Apache Arrow — does the heavy lifting off the UI thread.

See it in action

A real dataset, in the app — the data editor, its metadata view, an Analyze dialog and the resulting output.
