🔒 Runs Fully Offline — No API Key, No Upload

Turn a Spreadsheet Into an Insight Report With Charts, Without Sending Data Anywhere

Point the generator at any CSV or Excel file and it builds a report workbook with charts and a plain-language summary of the key findings — entirely on your computer, so confidential sales, finance and operations data is never uploaded to an AI or dashboard service.

Why Teams Hesitate to Feed Business Data Into Online Report Tools

Automated reporting is valuable, but the obvious online routes expose sensitive data and lock you into a subscription.

🔒

Confidential data in someone else's cloud

Uploading sales, margin or payroll spreadsheets to an online AI reporting service puts sensitive business data on a third-party server, often outside your control or compliance scope.

💳

Recurring fees for occasional reporting

BI and dashboard platforms charge every month regardless of how often you actually build a report, which is poor fit for periodic monthly or quarterly analysis.

🧱

Overkill for a single spreadsheet

Full BI suites need data modeling, connectors and training just to chart one file, when the real need is a fast, readable report from one workbook.

What It Does

A focused local pipeline from one spreadsheet to a shareable, charted insight report.

📊

Charted report workbook

Reads any CSV or Excel file and produces a report workbook with the relevant charts, ready to present or circulate.

📝

Plain-language summary

Writes a human-readable narrative of the key findings alongside the numbers, not just raw tables and graphs.

🔌

No connector setup

Works directly on local files with no database connectors, cloud accounts or data warehouse required.

🔐

Fully offline processing

All analysis runs on your machine with no API key, so there is no external AI call and no data leaves the company.

⚡

Fast periodic reporting

Re-run on a fresh monthly export in one step to refresh the whole report instead of rebuilding charts by hand.

🧰

Local dependencies only

Ships with the libraries it needs and runs on Windows, macOS and Linux without a hosted backend.
