Lightweight apps.
Real analytics.

DS and AI is where data science and analytics get put to work on everyday problems — practical, well-built tools that are quick to pick up and actually create value. Each one starts with a real question and ends with something you can use.

My Spending Pattern

Drop in a bank or card statement — CSV, Excel or PDF — and get your spending categorised, totalled and charted in seconds. No sign-up, no bank login, no waiting.

  • Nothing is uploaded. The file is parsed inside the page and never leaves your device.
  • Works with statements from most Indian banks and card issuers.
  • Automatic categorisation, month-on-month trends and a clean summary you can screenshot.
  • Try it on sample data first if you'd rather not use your own.
