Minchal
Extract, calculate, then explain.
- AI / Consumer
- Team Lead
- National finalist · HackXelerate 26'
Context
Minchal estimates which household appliance is driving an electricity bill, from photographed bills and appliance nameplates alone. Built as Team Lead at HackXelerate 26', a national-level hackathon, where it reached the finals.
Approach
A three-step pipeline with the model at both ends and arithmetic in the middle: Gemini extracts, deterministic code calculates, Gemini explains. It is the same deterministic core and LLM language layer split, in a consumer product.
System
Gemini extract
Reads the photographed bill and appliance nameplates
Deterministic calculate
Estimates which appliance drives the bill
Gemini explain
Puts the result into plain language
Build
- Gemini-extract, deterministic-calculate, Gemini-explain pipeline
- Input from photographs only: a bill and appliance nameplates
Challenges
- Attributing a bill to one appliance from photographs alone: a bill and appliance nameplates are the only inputs.
- Keeping the model out of the arithmetic. Gemini reads and explains, deterministic code calculates.
Result
National finalist at HackXelerate 26'.
- Finalist
Learnings
Let the model read and explain. Keep the numbers in code.
