A $9,800 discount when the average is $196. You'd never catch that scrolling.
Drop your invoice, expense, or transaction file. Aynalyx compares every row across all numeric columns and surfaces the ones that don't look right. Results are ranked by severity, not by amount.
Your clients' data stays on your computer.
This app runs in your browser. No files are uploaded, no data is transmitted. You can use it with your clients' financial data.

Aynalyx compares each row to the rest across all numeric columns and tells you what stands out. "This discount is 50 times higher than normal."
See totals by month, by vendor, by employee - then spot which groups stand out from the rest.
Define your own ratios (like Expense ÷ Revenue) and find the rows where the ratio is unusual.
Your data never leaves your computer. No uploads, no servers, no cloud. Period.
"This amount is three times higher than average" - not math formulas. Anyone can understand.

One score that sees all your metrics at once: no black box, just proven math.
We convert every value to a Z-score: how many standard deviations from the average. This makes all columns comparable, whether it's dollars, quantities, or percentages.
For each row, we add up the Z-scores from ALL selected columns. This creates one number that reflects how unusual the row is across everything.
Rows with the highest composite score rise to the top. These are the rows that stand out the most when looking at ALL your metrics together.
Each column is colored from light (normal) to dark (high). Scan a row: multiple dark cells = multiple unusual values = higher rank.
Each row gets a single score that summarizes how unusual it is. Higher = more anomalous.
How it's calculated:
Score colors: Green (0-2) = Normal, Teal (2-4) = Notable, Blue (4-6) = High, Purple (6+) = Very High
Z-scores are used by data scientists, auditors, and analysts worldwide.
No hidden algorithms. Normalize, combine, rank. That's it.
Export to Excel with all values visible. Check any number.
All calculations happen in your browser. No data sent anywhere.
"Show me the transactions that are much larger than our typical spending."
"Group by month and tell me which months have unusual totals."
"Group by employee and show me whose totals are different from the rest."
"Which items have sales or inventory levels that stand out?"
"Calculate Profit ÷ Revenue and show me where that ratio is unusual."
"Prioritize everything so I know where to focus my time."

We compare every row to all the other rows. If a value is much higher or lower than average, we flag it. We also look for combinations of values that don't fit the usual pattern. It's like having an extra pair of eyes that never gets tired.
The web demo works with up to 100 rows. The full version has no limits, exports to Excel, and runs as a Windows app that works completely offline. Same logic, just more capacity.
We support CSV files, Excel 2007+ (.xlsx), and older Excel files (.xls). Basically any spreadsheet you'd normally work with.
Aynalyx uses proven statistical methods: Z-scores for standardization, Mahalanobis distance for multi-dimensional outlier detection, and robust median-based estimators to handle skewed data. These are the same techniques used in audit analytics, quality control, and academic research, automated and accessible without a statistics background.
