The story in 90 seconds

One evening in Kengeri: how Ravi's quote takes until the next day by hand, and how it gets done before 7:41 PM with Nakshe.

How the numbers hold up

A wrong quantity costs the shop money or the job. So the AI never does the maths.

  1. The AI only readsGemini turns the sketch into dimensions and Sarvam turns the voice note into text. Neither one calculates.
  2. The contractor confirmsThe plan is read back on WhatsApp before any price is shown. Anything missing, like a roof slab, is asked for.
  3. Rules do the countingIS 1200 take-off rules, unit-tested on known rooms. Every line shows how it was counted.
  4. The owner approvesNothing leaves the shop without one tap, and the owner can edit any rate first.
