Review Alert & Rating Trend Monitor — Voice of Customer Delta (Vigia)

Turn your own review exports into an early-warning system — pay only for reviews that need action.

Feed Vigia the review data you already have (Trustpilot, Google, your own export, or any source you're authorized to use) and get back only newly observed reviews, classified by topic and severity, with a rolling rating trend — not just a dump of rows.

Why choose Vigia

• Only actionable reviews are charged — most review trackers bill per review scraped whether it needs a response or not. Vigia's non-urgent reviews are delivered free; only low-score/urgent reviews generate a billable alert.
• Rating trend, not just a snapshot — in monitor mode Vigia remembers your historical average rating and reports rating_trend: is satisfaction improving or sliding since last time? Raw review dumps never give you this.
• Topic classification — every review is tagged shipping / quality / support / pricing / other, so you see what is driving complaints, not just that they exist.
• Severity triage — critical / moderate / minor, so the worst reviews surface first.
• Aggregate signal — each run returns a review_signal: counts by topic and severity, this run's average rating vs. historical average, and the single most urgent review.
• Fair pricing — hard maxTotalChargeUsd cap; never billed without a result.

Honest positioning

This actor does not scrape Trustpilot, Google, or any platform itself — it's a delta, triage, and trend engine over review data you already have (your own export, or output from a licensed review-scraping actor you're authorized to use).

Input

• currentReviews / previousReviews — your review records (review_id, rating, text, ...).
• monitorEnabled / monitorId — persistent delta mode; first run is a free baseline.
• maxTotalChargeUsd — hard spend cap.

Output

One row per new review: change_type: new, actionable, severity, topic, signals. Plus a RUN_SUMMARY.json with the aggregate review_signal (including rating_trend).

FAQ

Does this actor fetch reviews from Trustpilot/Google itself? No — see Honest positioning above. What makes a review "actionable"? A rating of 2 or below, or urgency language (e.g. "no response", "refund", "scam"). How is the rating trend computed? Vigia keeps a rolling count/sum of ratings per monitor in a persistent store, so each run can compare its average against your full history.
