The no-retention policy was the deal-maker. Compliance signed off immediately because data leaves the system as fast as it arrives.

Frequently Asked Questions

Answers to the setup questions we hear most often.

Is it really free?

Yes. You receive 10 pages as a one-time welcome bonus. We ask for a payment method to prevent duplicate accounts and enable pay-as-you-go usage once you go beyond the free allowance.

Why do I need to add a payment method?

It prevents abuse from repeated signups and ensures we can charge pay-as-you-go usage automatically. You won't be billed for the initial 10 pages.

What file types can I analyze?

Excel (.xlsx, .xls), CSV files, and PDF documents including AWS bills, Azure invoices, utility statements, bank statements, and more.

Do you store my data?

Uploaded files are analyzed in real-time and are not retained after processing. We may store analysis results and usage records so your account, billing, and notifications work.

What counts as a page?

1 PDF page, 100 Excel rows, or 5KB of text equals one page. Most bills and reports use 1-3 pages.

How accurate is the anomaly detection?

No anomaly detection tool can guarantee perfect results. ainomaly.io is designed to highlight likely issues so humans can review them faster.
