AI tools typically use simplified categories—injury description, treatment timeline, and whether scarring occurred—to produce a range. That can help you ask the right questions, but it can also mislead you if your case doesn’t match the tool’s assumptions.
In Naperville, the “real-world” variables that insurers focus on include:
- Timeliness of medical documentation after a bite (especially if swelling, infection, or nerve pain developed later)
- Consistency between what you reported and what clinicians recorded
- Evidence of notice (did the owner know about prior behavior, or was it foreseeable based on the dog’s history?)
- Where the incident occurred—for example, a bite during a delivery/errand, at a residence during a visit, or near high-foot-traffic areas
A calculator may output a number, but settlement value in Illinois depends on what can be proven and how well your medical record supports causation and severity.
