Know about Data Drift AI Intelligence™
Everything you need to know before you start: what it does, who it is for, what to load and what you get.
What it does
Data Drift AI Intelligence answers one question: is this month's file safe to use? Load the last good version of a dataset and the new one. In seconds you see which columns were removed, added, renamed or changed type, which rows were added, removed or changed, how much every column drifted, and the quality alarms — blanks rising, invalid emails or GSTINs, duplicate IDs, values far outside the old range — with a clear verdict and a short list of what to check today.
The problem it solves: files that load without errors can still be wrong. A source system renames "Segment", someone types "N." instead of "North", a third of the emails go blank, a PIN code becomes "PIN-560001". Nothing fails — but dashboards, reports, ML models and month-end numbers built on that file are quietly wrong, and people find out weeks later.
Who it is for
| Who | What they compare | What they get |
|---|---|---|
| Data engineer | Yesterday's and today's extract before loading the warehouse | Schema changes, type changes, duplicate keys — before the pipeline breaks |
| BI / MIS analyst | Last month's and this month's report data | Which columns drifted, so a dashboard number is explained before it is questioned |
| Data scientist | Training data vs new scoring data | Drift (PSI) for every feature, new categories the model has never seen |
| Master-data owner | Customer, vendor or product master versions | Rows added, removed and changed; invalid GSTIN, PAN, email, phone |
| Finance / operations | Price lists, rate cards, credit limits | Every value that moved more than 20%, with the old and new value |
| Consultant / auditor | A client's data before and after a migration | Proof of what changed, in an Excel workbook and a one-page brief |
What you load
- Two versions of the same table — the old (last good) file and the new file. Excel (.xlsx), CSV or JSON, up to 80 MB each.
- ☁️ From your cloud — paste a secure, read-only link to a file or folder in Azure Blob Storage / Data Lake, Amazon S3 or Google Cloud Storage. For an Azure folder you get a searchable list of files to pick from. The link goes straight from your browser to your storage.
- Databases (Azure SQL, SQL Server, Snowflake, Oracle, MySQL, PostgreSQL) — export the table or query to CSV and load it, or drop the export into your cloud storage.
- A key column (an ID or code) lets you see rows added, removed and changed. It is found for you.
What you get
Downloads: a Data Drift Workbook (Excel) with every finding, column, category share, added / removed row and changed value — and a one-page Drift Brief (Word) for the data owner.
How it works — in 5 steps
Your data stays with you
🔒 Both files are read and compared inside your browser. They are never uploaded to QuantumData servers. Cloud links go directly from your browser to your own storage — QuantumData never sees the link or the data. Only sign-in, your licence and payment use our secure service.
🤖 The AI that learns also runs inside your browser; your "expected" answers and your "what changed" history are kept on your browser only.
✨ Ask AI is optional. Before anything is sent you see the exact summary — column names, types, drift levels and counts — and tick "I agree". Row values are never sent, and nothing is stored.
