The synthetic research layer

Built for survey and research teams who need to understand reactions, reduce risk, and deliver deeper insights — using realistic synthetic audiences that scale with every study.

Know what your audience is thinking,

A hybrid engine that blends real people with synthetic personas, routed through up to eight language models, so every answer stays grounded and every audience is reachable.

01
A real panel, not just a prompt
Chorus is full-service: we recruit and run an actual human panel, and every synthetic persona is grounded in that real response data \u2014 not a guess.
02
Up to 8 models, reconciled
Each persona is routed through a mix of leading LLMs and the answers are reconciled against each other, so no single model's blind spots skew the result.
03
Reach the hard-to-survey
We help you find and model the small, niche, or hard-to-reach minority groups that traditional panels struggle to recruit at any usable scale.
04
Model once, ask anything
Build a persona library once, then query it as many times as you like \u2014 no extra recruiting cost, no waiting on fieldwork \u2014 for as long as the study stays relevant.

What research teams are saying.

“Chorus lets us pressure-test messaging before a single interview is scheduled. What used to take weeks of fieldwork now takes an afternoon, and the fieldwork we do run is sharper for it.”

Insights Lead

“We ran our first synthetic panel alongside a live study just to check ourselves — the directional read matched. It's now the first thing we reach for before every proposal.”

“It helped us do faster, better research. Chorus gives our team a credible first read on audience reaction days before we'd normally have anything to show a client.”

Your data stays yours.

Every study runs in an isolated environment. Nothing is shared, sold, or used to train models outside your account.

Private by default
Your surveys, personas, and results are never shared with other customers or used to train any model outside your account.
Private cloud
Run Chorus in your own isolated cloud instance, separated from every other customer's data and workloads.
On-premises option
For teams that need it, Chorus can be deployed entirely within your own infrastructure, with no data ever leaving your network.
Encrypted throughout
Data is encrypted in transit and at rest, with access controls scoped to your team from day one.

Ask 12 strangers
what millions will think.

Use synthetic audiences before fieldwork to test the angle, expose objections, and walk into the real study with sharper questions.
