slow-cooker-converterUse when you want to cook a regular stovetop/oven recipe in a slow cooker or Instant Pot (or vice versa) — converts cooking times across 7 appliance modes with the physics of WHY (collagen→gelatin at 60-70°C, milk curdles at 2h+, rice liquid ratios change in sealed pots), checks capacity fill (half-full min, two-thirds max), detects ingredients that must be added late or omitted entirely (dairy, pasta, fresh herbs, thickening), and produces a step-rewritten recipe with an insert-at-mark timeline.
smell-source-detectiveUse when your home has a mystery smell you can't locate (sewage in the bathroom morning-only, fish smell with no fish, musty bedroom, gas whiff near the stove, sweet chemical in the hallway) — a diagnosis engine that ranks probable sources from smell type + location + timing triggers, separates the four DANGER smells (gas, smoke, sewage backup, dead animal in walls) that need immediate action from the annoying-but-safe ones, gives a no-tools localization protocol (sniff-mapping, dry-trap tests, fixture-by-fixture elimination), and surface-specific kill protocols (dry P-traps, enzymatic vs bleach, mold remediation decision line).
