Frequently Asked Questions

ReviewSignal is a consumer review intelligence platform that turns public consumer reviews into desk-ready chain intelligence. Instead of dumping raw data or inflated directory counts, we focus on the active monitored universe and deliver cascade alerts, dashboards, research briefs, and exports that an investment team can actually use.

ReviewSignal is built for research teams that want a focused monitored workspace and an honest path from public preview to paid coverage. The product is designed to prove fit quickly instead of selling an inflated institutional wrapper.

We process public consumer review data and only surface chains with real current coverage in the live product. The active monitored universe changes as density improves, so customers see the chains that are actually ready for dashboard, report, and export delivery.

We cover consumer chains across restaurants, coffee, retail, grocery, pharmacy, and adjacent categories. Trial and paid plans open selected or broader monitored sets depending on tier. View the current chain directory.

We use a multi-layered NLP pipeline. Neural Core generates 384-dimensional sentence embeddings using MiniLM (all-MiniLM-L6-v2) to capture semantic meaning beyond simple keyword matching. Isolation Forest anomaly detection flags statistically significant deviations from historical baselines. Sentiment scores range from -1.0 (extremely negative) to +1.0 (extremely positive), with thresholds of ±0.10 for gap-free classification into positive, neutral, and negative categories. Learn more about our methodology.

The live dashboard refreshes daily. Our monitoring jobs watch freshness and coverage gaps so that only chains with current usable data appear in the active monitored universe. Reports are regenerated on their delivery schedule as new data arrives.

Echo Engine compares sentiment against rolling baselines and propagation context so recurring spikes can be flagged instead of treated as clean signal. It reduces seasonal noise; it does not guarantee that every seasonal effect is removed. Confidence is derived from the live propagation runtime rather than a decorative placeholder layer.

Echo Engine generates trading signals by analyzing sentiment trends, anomaly patterns, and geographic or brand propagation effects. The product surfaces direction, sentiment delta, and review count from the live monitored universe, with confidence shown only when a real runtime payload supports it. Signals are designed as inputs to your existing investment process, not standalone recommendations.

The 14-day free trial includes a self-serve workspace with 5 monitored chains, preview reporting, and 100 API calls. No credit card is required. The trial expires automatically — there is no auto-conversion to a paid plan. Start your free trial.

Signal (€299/mo) covers 10 selected chains with daily signals. Starter (€999/mo) expands to 30 selected chains with weekly research briefs and benchmark context. Developer Program (€1,500/mo) keeps that 30-chain scope but adds API docs, webhook delivery, and integration support. Professional (€2,500/mo) opens the active monitored universe and deeper analysis surfaces. Enterprise (€5,000/mo) adds custom tracked coverage, analyst support, and custom delivery.

Stripe-managed subscriptions can be cancelled at any time from the Billing page via the Stripe Customer Portal, with no penalties or cancellation fees. When you cancel, your service continues through the end of your current billing period. We do not offer partial refunds for unused portions of a billing period. Provisioned workspaces should contact team@reviewsignal.ai because they do not all use the same Stripe self-serve flow. See our cancellation policy for full details.

Standard self-serve plans are billed month-to-month. If you need a custom enterprise agreement or invoice-based arrangement, contact our team at team@reviewsignal.ai.

Yes. Paid plans include REST API access and CSV/JSON exports within their plan limits. Developer Program and above add webhook delivery for downstream systems. API authentication uses API keys or JWT-based access depending on the surface you use.

Data is available via REST API, downloadable CSV exports, and PDF research reports. Developer Program and above can also receive data via webhook push notifications, while Enterprise adds custom delivery formats.

Yes. Our REST API integrates with any platform that supports HTTP/HTTPS requests. Developer Program adds the API-first support path with docs, webhooks, and integration help. Enterprise clients can also request custom delivery formats.
