Accuracy & Confidence Scores Explained
What confidence scores mean and when to trust AI nutrition data
⚡ Quick Summary
Confidence scores show how certain the AI is about its food identification. 95-100% = highly reliable. 85-94% = good estimate. Below 85% = use caution or manual entry.
What Confidence Scores Mean
95-100%: Elite Accuracy
Crystal clear photo + common food + visible label. AI is highly certain about identification and nutrition data.
85-94%: Good Estimate
Clear photo of well-known food. Portion estimate may vary ±10%. Safe for daily tracking.
Below 85%: Use Caution
Blurry photo, unusual food, or hidden ingredients. Consider manual entry or re-scanning with better photo.
Why We Show Confidence Scores
Most food apps give you nutrition data without telling you how reliable it is. That's misleading. If the AI guesses "500 calories" but the real value is 800, you'll track incorrectly and won't hit your goals.
Food Identifier AI shows confidence scores because we believe in transparency. If the AI is 75% confident, we tell you—so you can decide whether to trust the estimate or manually verify.
This honesty builds trust and helps you make better decisions about your nutrition tracking.
