Accuracy and methodology

We do not claim universal percentage accuracy. Here is how estimates are built and where they can vary.

Calculation pipeline

Describe or photo input → parsed components → canonical food match → preparation state → weight → verified per-100g nutrition → component total → meal sum. Missing nutrients stay unavailable — never shown as zero.

Confidence bands

  • High — exact products or simple weighed foods with authoritative data
  • Medium — correctly identified variable dishes with known portions but recipe uncertainty
  • Low — unmatched components, unclear weight or major assumptions

Limitations

Restaurant oil, batter absorption, hidden ingredients and regional recipes change calories. Ranges show likely bounds; the central estimate always falls inside the displayed range. Unmatched components stay visible — we do not silently drop accompaniments.
