How it works

From file to insights

Designed for fast iteration: preview first, generate second, refine later.

1

Upload

Drop a dataset (.csv, .tsv/.tab, delimited .txt, .xls/.xlsx, .json). We create a temporary session and keep it isolated.

2

Preview

We detect headers and show the first rows so you can confirm the structure before running analysis.

3

Generate

Streaming progress, interactive charts, and a readable executive summary you can share.

Features

Built for real-world datasets

Clean output, robust parsing, and charts that adapt to your data.

Adaptive time granularity

Short spans use seconds (or epoch-ms for sub-second data). Long spans roll up to days or months.

Multiple chart types

Time series, distributions, correlations, and categorical breakdowns — chosen automatically.

JSON-safe outputs

Charts and summaries are sanitized (no NaN/Infinity). Ready for rendering and export.
