Voice-of-Customer Synthesis AI Agent

Establish what a recording was permitted to be used for before reading it, let each theme rest only on the words that survive that test, and hand the quote to the insight lead.

What this agent does

Draws the theme, never publishes the quote

In
01

A call is read, and whether it could lawfully be recorded was settled before the agent reached it.

02

A recording leans on 18 U.S.C. 2511(2)(d), which bars liability rather than granting a right.

Reason
03

A call comes from an all-party state, while Massachusetts asks only that nobody recorded in secret.

04

A tone score off the agent, not the caller, is what Article 5(1)(f) has prohibited since February 2025.

05

A caller sentiment read is not prohibited; Annex III point 1(c) makes it high-risk from December 2027.

Decide
06

A transcript tells speaker A from speaker B, and joining that label to a name is what is under challenge.

07

A recording kept for quality assurance is read for insight, and the new purpose is tested, not assumed.

Out
08

A theme is drawn, and it names the calls and the words under it rather than standing on its own.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

Reading, clustering and attribution belong to the agent. Publication belongs to a named insight lead, who puts the quote in front of the business and answers for it.

Example workflow

One theme, recordings to publication

AgentHuman
1Feedback receivedSupport calls, tickets, survey verbatims, community threads or in-app messages
2Consent basis establishedThe jurisdiction the call came from, the disclosure made, the purpose it was recorded for and the date
3Themes drawn from the wordsThe theme, the quotes under it, the sources they came from and confidence
4Controls appliedConsent checks, purpose checks, attribution checks and drafting confidence
No human action required

Stages 1 to 4 run unaided, and nothing is published at any of them — the agent is reading, and the insight lead lane opens at the attribution gate.

5DecisionSplits at the attribution gate
Attribution complete

Goes to the named insight lead.

Anything unsourced

Adds a privacy lead read first.

Insight lead review

The theme is held with its quotes, their consent basis and the sources they came from.

Publish · Add source · Send to privacy review

7Outcome evaluatedAttribution accuracy, consent coverage, lead corrections and what review found
Corrections

Each insight lead correction is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Publishing a customer quote outside the company.
Deciding that a recording was lawfully made.
Approving a recording for a purpose it was not made for.
Signing off a theme for a board pack.

Nothing is published except by a named insight lead, inside the agreed boundaries.

Example output

One theme, annotated

This serves an insight team who may have to say where a customer sentence in a board pack came from; below is one theme exactly as the agent leaves it.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every themeFrom the words that produced it
03Evidence

Where the words came from

Attention measurement and the marketing analytics agents measure campaigns; this reads what customers actually said, and its first question is whether it was allowed to.

01Approved path

The consent came first

Move the state a call came from, or the purpose it was recorded for, and the same sentence stops being usable, with nobody having lied.

02Human review

What was checked, and not found

Checked across the statutes surveyed: nobody at the company signs anything. The BIPA written release is executed by the subject, the retention policy is made public rather than filed, and Illinois has no regulator to receive it.

04Build an evidence trail

The quote, the recording it came from and the consent behind it stay together.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

How Nestack evaluates it

Evaluate the whole reading — not only the theme that comes out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Affected slices

All-party audio absorbs the corrections

A theme-level attribution figure can read clean while calls from all-party states carry most of the corrections. Nestack reports the correction rate by theme, not only in total.

Evidence-linked improvement

What an unconsented quote costs

A cycle ends when the quote pulled from an unconsented call is a regression case. That suite is what the next theme issued is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Correction rate rises on calls from all-party states.

02Diagnose

The customer sentence in the board pack, pulled from a call recorded in a state that wanted both sides to agree, is worked backwards until one cause is left standing.

03Improve

Number the change; the quotes that forced it are attached to it.

04Verify

One quote case still red is enough to hold the release back.

05Learn

It stays a standing test, and the consent rules are amended alongside it.

Learn → DetectThe return edge. The next theme is measured against a suite one case longer.

Typical build scope

Next step · Customer Success AI agent

Build a voice-of-customer agent around the consent your last quote never wrote down.

Show us one theme you reported last quarter and the calls its quotes came from. The recording came first, and whether it was lawful was settled before anybody read a word of it. What no quote can carry, we name before it reaches a board pack.
