How it works

From file to insight
in under 30 seconds

No data engineering. No SQL. No waiting three days for the BI team.

01
Upload your file

Drop any CSV or Excel — up to 2GB. FastBI parses every column instantly, detecting types, ranges, and cardinality before you blink.

02
AI plans the layout

Intent planner reads your goal. Column intelligence picks the right metrics. A spatial layout engine composes pages — never repeating a column twice.

03
Ask anything

Type any question. Cohort, RFM, anomaly, trend — every prompt yields a fully composed multi-page dashboard, ready to share or drill into.

Ask a question.
Watch the dashboard rebuild.

A sample retail file, running entirely in this page. Pick a question and the KPIs, the chart and the written read-out recompose — the same loop FastBI runs against your own file.

The UK carries 34.1% of revenue — more than Germany and France combined. That is concentration worth naming: a 10% swing in one market moves the group total by 3.4%. The other five markets are within £1.2M of each other, so there is no second pillar.
