What is FastBI?
FastBI is a data-analysis tool that turns any CSV or spreadsheet into a complete, fixed-page dashboard — charts appear quickly; the full AI narrative can take 1-3 minutes depending on dataset and model availability. It is built around one idea: the numbers are computed deterministically in Python, and AI only narrates over them. The accuracy layer is never optional.
How FastBI works
When you upload data, FastBI profiles every column (identifier, dimension, measure, date, or flag), then derives named business measures — Revenue, Return Rate, Average Order Value, Units per Order, Churn Rate — by executing pandas expressions against your data. These become a measures manifest that the whole product reads: the KPI strip, the chart planner, the findings, and the report.
The dashboard is a fixed 16:9 artboard, like a slide, so what you see is exactly what exports. Charts that do not fit flow onto a second page rather than scrolling. Zoom is a single transform, so charts never re-render as you zoom.
Who FastBI is for
Analysts and operators who live in spreadsheets and notebooks and want a dashboard without building one — and without trusting an AI to do the arithmetic. FastBI runs as a web app; its single Python package (fastbi-io, imported as import fastbi as fbi) is not yet published on PyPI — private install via INSTALL-PRIVATE.md.
How FastBI is different
- Deterministic first. Every metric is computed in pandas and is hand-verifiable. The AI names measures and writes prose; it never does the math.
- Local-LLM mode. On the Pro tier you can point FastBI at a local model (Ollama, LM Studio) so your data never leaves your machine for narration.
- Free means the full deterministic product. Plus 5 AI prompts per rolling 24 hours. The entire measures + dashboard engine is included — accuracy is not paywalled.
Pricing in one line
Free is the deterministic product plus 5 AI prompts per rolling 24 hours. Pro is $10/mo for AI insights via our backend. Max is $30/mo and adds local-LLM mode. Business is a contact flow for teams.
