Support teams usually find out a customer was unhappy when the cancellation email arrives. The warning signs were in the ticket thread weeks earlier — they were just spread across hundreds of conversations nobody had time to read. Sentiment Pulse scores every conversation, groups them by what people are actually complaining about, and shows exactly which words produced each score.

Explainable scoring, not a black box

Most sentiment tools return a number between -1 and 1 and expect you to trust it. When that number disagrees with your reading of the ticket, there is nothing to inspect and no way to correct it. Agents stop believing the tool, and a dashboard nobody believes is a dashboard nobody opens.

Every score here traces back to the specific terms, modifiers and signals that produced it. Open a conversation and you see which phrases pushed it negative, which intensifiers amplified them, and what the final weighting was. If the engine is wrong, you can see why, and you can fix it by editing the lexicon rather than filing a support request.

The problems that break naive sentiment analysis

Counting positive and negative words gets you a tool that fails on ordinary English. Three failure modes matter in support text specifically, and each is handled explicitly.

Negation
"Not helpful" is not a positive sentence containing the word helpful. Negation flips the polarity of the terms it governs, within a bounded window so it does not leak across the whole message.
Contrast clauses
"The onboarding was great, but billing has been a nightmare" is a complaint. The clause after the pivot carries full weight; earlier clauses are discounted to roughly a third, because that is how the sentence actually reads.
Polite formulas
"Quick question" and "thanks in advance" are courtesy, not praise. Common phrases are matched before single words so they cannot inflate a score that should be neutral.

Topics, not just scores

A falling average tells you something is wrong but not what. Conversations are clustered by what they are about — billing, onboarding, performance, the interface, support responsiveness — so a drop can be traced to a cause.

Each topic carries its own volume and sentiment trend. A topic that is small but sharply negative and growing is usually the one worth acting on first, and it is the one a single platform-wide average hides completely.

How a conversation is scored

The pipeline is deterministic. The same text always produces the same score, which means a number in a report can be reproduced months later — something a hosted language model cannot promise you.

  1. Normalise and match phrasesMulti-word phrases are matched first so idioms and courtesy formulas are not scored as their component words.
  2. Split into clausesThe message is divided on contrast pivots such as "but", "however" and "although", because those mark where the real opinion sits.
  3. Score terms with modifiersEach clause is scored from the lexicon, with intensifiers and diminishers scaling the terms they attach to and negation inverting them.
  4. Weight the clausesThe final clause carries full weight, earlier clauses about a third — matching how a reader resolves a sentence that changes direction.
  5. Add signals and classifyPunctuation emphasis, all-caps and escalation words adjust the result, which is then bucketed into a label and an urgency with the full breakdown attached.

Because it is a lexicon rather than a model, it is also editable. Industry terms that read as negative in general English but are neutral in yours — "charge", "dispute", "claim" in financial services, say — can be reweighted once and apply everywhere from then on.

Who it is for

Small support teams

Two or three agents and no analyst. The value is triage: urgent and angry tickets surface first instead of being handled in arrival order.

Customer success at scale

Account-level sentiment trends across every conversation, so a quiet account drifting negative is visible before renewal rather than after.

Product teams

Topic clustering turns support volume into a ranked list of what frustrates people, with the verbatim quotes attached for the ones worth reading.

Regulated industries

Deterministic scoring that can be reproduced and audited, with no customer text sent to a third-party model.

Customer Support Sentiment Analyzer terms explained

Sentiment analysis
Classifying text by the attitude it expresses — positive, negative or neutral — and, usefully, by how strongly.
Lexicon-based scoring
Scoring from a dictionary of terms with known polarity, adjusted by grammatical context. Slower to tune than a trained model but fully inspectable and reproducible.
Negation scope
How far a negating word reaches. "Not at all happy" must invert "happy"; an unbounded scope would wrongly flip everything that follows.
Contrast clause
The part of a sentence after a pivot like "but". It generally carries the speaker's actual position, which is why it is weighted more heavily.
Escalation signal
A marker that a conversation is about to get worse — threats to cancel, mentions of a competitor, repeated follow-ups on one issue.
Topic clustering
Grouping conversations by subject so sentiment can be attributed to a cause rather than reported as one unhelpful average.
Churn risk
The likelihood a customer leaves. Sustained negative sentiment on billing or reliability topics predicts it far better than a single angry ticket.

Frequently asked questions

Can I see why a message scored the way it did?

Yes, and that is the main reason to pick this. Every score lists the exact terms, their base weight, the applied weight after negation or intensifiers, and the signals detected. No score appears without its reasoning.

Does it understand "not bad" and "great, but"?

Both. Negators flip polarity on the words they govern, intensifiers scale it, and in a sentence like "X was great, but Y was broken" the clause after the contrast carries the verdict — because that is where the real message is.

Can I teach it our own vocabulary?

On Growth and Scale you can add custom terms with your own weights. "Stockout" is neutral English but always bad for your customers, and the model should know that.
