Perforvisor: a 5★ review said "Needs to be more clean." Open models caught it.
Description and use
Perforvisor turns reviews into a knowledge graph and gives restaurant owners concrete actions, uncovering hidden complaints masked by average ratings.
Problem
Restaurant owners have hundreds of reviews but lack time to read them; star averages mask specific complaints.
Outcome
Perforvisor turns raw reviews into actionable insights, revealing hidden complaints that star ratings hide, and provides a weekly to‑do list grounded in customer language.
Workflow
- Connect business via Google Maps or paste reviews
- Perforvisor reads each review with Qwen3-4B to extract aspects, sentiment, and claims
- Builds a knowledge graph merging semantically identical claims
- Generates a verdict and up to three actions prioritized by complaint frequency
- Flags reviews with rating–text contradictions or near‑copy‑paste
- Compares the business with up to three competitors on the same aspects
- Answers ad‑hoc questions using retrieved reviews and citations
Evidence
Perforvisor reads every review with a small open-weight model, turns what customers say into a knowledge graph and gives the owner a verdict, up to three concrete actions and the reviews behind each one.
