MULTI-AGENT DECISION SIMULATOR

Rehearse reality before you live it.

Assembly reads hundreds of real sources — news, forums, social media — and simulates how real people will debate and decide on your question. No surveys. No guesswork. Tested against real-world polling data and accurate enough to matter.

SIMULATE

Real agents debate your question

Hundreds of AI agents with distinct real-world personas argue your question across multiple rounds — grounded in what people actually say online, not what they say in surveys.

EVOLVE

Opinions shift and converge

Agents challenge each other, shift positions, and form emergent consensus. Watch opinions move in real time — or watch genuine disagreement hold firm.

TWO LABS. ONE ENGINE.

Same simulation core. Different use cases.

LIVE · BETA

Public Opinion Lab

For campus decisions and public policy questions.

Any question where you need to know how people will really react — before you commit. Student proposals. Policy debates. Research questions. Community decisions. Free during beta.

Should cities ban single-use plastics? Would students pay for an AI study tool? Should remote work be a legal right? Should college athletes be paid?

Launch Lab

For D2C brands launching products, pricing, or campaigns.

Pre-launch market simulation for D2C brands. Understand exactly who will buy, who won't, and why — before you spend the budget. The gap between what brands think customers want and what they actually want costs millions every year. Assembly closes that gap.

Will buyers pay $49 for this? How will our target demo react? What will competitors do better?

SEE IT IN ACTION

This is what Assembly produces for every question you run.

Should remote work be a legal right?

S  Sarah  [FOR]

Remote work access is fundamentally a quality of life issue. Commuting costs alone consume 15% of average worker income.

J  James  [AGAINST]

Mandating remote work eliminates employer flexibility and ignores industries where physical presence is non-negotiable.

M  Marcus  [FOR]

James raises a fair point on physical industries — but knowledge workers represent 40% of the workforce and have no such constraint.
