Built by an analyst, for analysts.

Who builds DataLens AI

I’m Chinmay Raibagkar — a marketing analyst focused on data and automation. My week runs through data-warehouse pipelines, ad platforms, and dashboards, which is exactly where DataLens was born: as the tool I kept wishing existed.

Every feature traces back to a real Monday-morning problem — numbers that need defending, reports that keep getting rebuilt, and questions that deserve answers faster than a ticket queue. The content on this site — the blog, the glossary, the calculators — comes out of the same work: the definitions and discrepancies I run into building and using DataLens myself.

Why DataLens exists

Most AI tools for data hand you a confident number and no way to check it. In marketing that is worse than no answer: Google Ads, Meta and your own database already disagree, and the person in the meeting needs to know which figure to defend. So DataLens is built around one rule — every number arrives with its receipt: the SQL that produced it, the sources it read and what the query cost. Nothing is asserted that wasn’t fetched.

It connects to Google BigQuery, Google Ads, Meta Ads and spreadsheets, runs only read-only queries, and shows the cost of a warehouse query before it runs. The security page covers how data and credentials are handled.

How the content on this site is made

The blog, glossary and calculators come from problems I hit building and using DataLens. A few standards apply to all of it:

• Every calculator shows the formula it uses, a worked example and what it does not model.
• Glossary entries give the definition first, then the formula, an example and the common mistakes.
• Posts carry their publish date and, when the facts change, an updated date.
• Found an error? Email contact.datalensai@gmail.com and it gets corrected, with the updated date changed to match.
