A plug-in layer. Nothing to learn, nothing new to log into.

Why scores bunch in the middle

Generic AI plays it safe. By design.

Language models reach for the consensus: your strongest and weakest calls land three points apart, and the coaching goes generic. Calibration puts something underneath built to tell the difference.

The journey of one call

From transcript to observation, and what never survives the trip.

transcript · your recorderreceived

Buyer: Sarah here — we’re Meridian Foods, we pay £400 a month today…

Seller: Before I answer, one check: is the concern the setup work itself, or when it lands?

Buyer: It’s the timing. If it lands after week two, the setup work is fine.

{ primitive } → your stack

01 · Ingest

Peer reads a call your stack already recorded.

02 · Sanitise

Names, companies and prices are stripped before grading.

03 · Grade

Specialist graders sweep the call competency by competency, each grade anchored to its moment.

04 · Blind re-mark

A second model re-marks a sample of every batch, blind. Agreement is measured.

05 · The atomic observation

Each graded moment becomes one record: competency, grade, evidence, timestamp.

06 · Return — and destroy

Observations return to your stack by API or MCP. The transcript is destroyed.

Why Peer

One job: grade how people sell.

Gong and Chorus see the macro view: the whole call, what happened. Peer adds the micro view: each skill graded moment by moment against one universal standard, checked against trained human assessors. When the two disagree, the call comes back flagged with the moment that shows why.

Same assistant, same questions, with and without Peer’s data. Judging blinded.

A floor, not a ceiling: the corpus we measured on is harsh and silent on most of a call. Read the study →

What this unlocks

Questions you can finally answer with evidence.

“Is the new cohort actually ramping?”

Skill grades week by week, not activity counts.

“Who are my genuinely strong sellers?”

Graded evidence that survives a promotion debate.

“Can this team open the enterprise motion?”

Skill readiness for a new play, before you bet a quarter.

“Did the coaching work?”

The same competency, measured before and after.
