DataCello is a calm, native Mac app for inspecting columns, previewing tables, and running real analysis — regression, forecasts, classification, PCA — entirely on your machine.
Every column read, every model fit, every chart rendered happens on your Mac. There is no account, no cloud queue, no telemetry pipeline waiting for your rows. Open a file and it is simply… open.
CSVs are parsed in-process. Nothing is sent to a server to be analyzed.
CSV analysis runs on your Mac. The network is only used for App Store purchases, restore, or remote imports you start.
Results leave only when you choose: CSV, JSON, or copy straight out.
DataCello collapses the usual round-trip into a single calm workspace. No notebook to spin up, no kernel to wait on.
Open a CSV and read it at a glance — types, missing values, uniques, distributions, and correlations, column by column.
Pick a target, choose features, set options, and run. Configure, save, and review results in the same workspace.
Charts, metrics, and predictions export cleanly when you're ready to move into a deck, a doc, or a notebook.
Six families of analysis, each with sensible defaults and an inspectable result. Enough to answer the question before you open a notebook.
Fit linear and logistic models, read coefficients and fit quality.
Train a classifier on chosen features, inspect metrics and charts.
Project a series forward over a horizon you set, with a preview chart.
Run standard statistical tests and read the result in plain terms.
Reduce dimensions and group rows to see the shape of the data.
Model durations and event rates without leaving the workspace.
From an MCP client, inspect a CSV, let the LLM choose the analysis, run DataCello’s local engine, and open the result in the Mac app.

One window: data sources on the left, the active view in the middle, an inspector on the right. Dark, dense where it counts, quiet everywhere else.
