Simulated sessions with AI participants
A room full of active participants, each thinking for themselves.
Plenary convenes two to eight AI participants, each built from their own background, history, knowledge and position, and each kept in a separate context. Watch them react to a concept, or step into the room to rehearse an interview, a sales call or a meeting and hear back from every one of them.

- Aisha OkaforFreelance designerreplying to Tom Does your accountant chase your receipts every quarter? Mine charges extra for that.
- Mei LinDeveloperreplying to Aisha Only if it connects to the bank. Otherwise I'm still the one doing the chasing.
- Rafa SilvaCopywriterreplying to Mei If it can read a photo of a receipt, I'll do the rest myself.
- Tom BrandtPhotographerreplying to Aisha Okay, the April catch-up. If it kills that bill, I'm listening.
- Moderator Rapid-fire, privately again: would you pay $12 a month today?
- Fair. She does bill me for the April catch-up.
- Rafa would pay for less than I would. Different problem.
- Maybe, if it cuts the April bill.4 → 6
- Not without a bank connection.6 → 5
- Yes. Same as before.7 → 7
- Yes, today.8 → 8
Each participant forms a view in their own context before they speak. They hear what is said aloud and answer each other; their private notes and scores stay with them.
Watch the room, or take a seat in it
The same room runs three kinds of session. In some you observe and read the report. In others you are one of the voices, and the participants respond to what you actually say.
Put a concept, a price or a message in front of the room. Read how each participant reacted privately, then how they moved once they heard each other.
- Focus groups
- Concept and price tests
- Positioning tests
Step into the conversation yourself. The room responds to what you actually say, and afterwards each participant tells you how it landed with them.
- Interview prep
- Sales call simulation
- Meeting rehearsal
Bring outside perspectives into a brainstorm: participants who live with the problem, participants who have never seen it, and you if you want a seat.
- Brainstorms
- Pre-mortems
- Red-teaming a plan
Every participant has their own mind.
ChatGPT and Claude can play one character well. Ask either to play four and all four live in one conversation: each reads the others' backstories, every document, and your note about what you hope happens. They drift toward each other and toward you. Plenary gives each participant a separate context and controls exactly what crosses between them.
- BleedEach character can read what the others think, so their views converge.
- AnchoringThe first answer sets the tone for every answer after it.
- Your framing leaks inEvery character knows what you want, and tends to give it to you.
- Average opinionsWithout their own grounding, characters fall back on the model's default view.
their own Fourteen years in finance. Cut two vendors last quarter. Distrusts seat-based pricing. Owns the SSO rollout. Went through a vendor breach in 2023. Uses the product daily with a team of nine. Rarely asked. Runs forty renewals a year and is measured on savings. Shared experience
set by you All four work at Northwind and sat through last year's rollout. This is the only common ground, and you put it there. Knowledge
their own Last year's invoice. The Q3 budget memo. Your security questionnaire and SOC 2 report. Her team's support tickets. A competitor's quote, 8% lower. Session memory What was said aloud in this call. Everyone hears it; each keeps their own private notes on it. Never crosses Another participant's private notes · another participant's documents · your goal for the call · anything from another session
Their biases stay theirs
Derek's distrust of vendors shapes Derek's answers. It does not seep into Lena's, because Lena's context has never contained it.
Common ground is set on purpose
Whatever the room shares, you put there: a company, an event, a market. Nothing else is shared by default.
They listen, then think alone
Each participant hears what is said aloud and forms a view of it in their own context before anyone replies. That is what makes the perspectives outside ones.
