Overcome Feedback Overload: From Chaos to Clarity with Sentor

In today's data-rich world, customer feedback floods in from reviews, social media, and support tickets. But without the right tools, it's overwhelming noise. Sentor turns this chaos into crystal-clear, actionable strategies using advanced entity-based AI.

Traditional Tools Leave You in the Dark

  • Sifting through thousands of reviews manually? It's exhausting, time-consuming, and riddled with human bias.
  • Basic sentiment classifiers spit out vague "positive/negative" labels—useless for pinpointing what exactly frustrates customers.
  • You see the anger in feedback, but uncovering the root causes? That's guesswork without entity-level precision.
  • Competitor benchmarking feels like comparing apples to oranges—fragmented data makes true insights impossible.
  • Missed patterns mean lost revenue: Unaddressed complaints snowball into churn you never saw coming.
  • Product roadmaps built on incomplete intel? You're innovating in the dark, wasting resources on the wrong priorities.

Sentor's 5-Step Intelligence Framework

  1. Capture Everything: Ingest feedback seamlessly via our REST API or Python/JS SDKs—no limits on sources, from reviews to social streams.
  2. Analyze with Precision: Our entity-based AI dissects text to reveal sentiment on specific aspects (products, services, competitors)—far beyond simple polarity.
  3. Cluster Smartly: Configurable grouping uncovers hidden patterns in positives and negatives, surfacing trends your team can act on immediately.
  4. Compare Confidently: Side-by-side analysis of your brand vs. rivals—call the API twice per entity and get benchmarks that drive market dominance.
  5. Act with Insights: Generate exportable reports, set real-time alerts, and track trends to turn data into decisions that boost satisfaction and revenue.
