How the browser mode works

When no backend is configured, the page applies keyword-driven heuristics calibrated from the original model to estimate the probability an email is spam.

  • Spam indicators: classic trigger words ("free", "urgent", "verify") yield higher scores.
  • Ham indicators: business-friendly language ("meeting", "report", "thanks") reduces false positives.
  • Threshold: adjustable via APP_CONFIG.spamThreshold (default 0.70).
