FrançaisThe engine
No script. No decision tree.
Say the same unexpected thing to both. The last generation walks a flowchart; this one listens.
“Honestly? Our onboarding is our weak spot.”
→ node 7
→ node 12
“I understand. Our pricing is very competitive.”
Node 7 fires. The tree can’t hear you.
“Appreciate the honesty. So how do you de-risk my first month?”
A listener’s reply — it reacts, it doesn’t retrieve.
The counterpart
Behavior, not answers.
Every scenario casts its counterpart with a behavioral brief — how they stall, what convinces them, when they walk away. Difficulty doesn't change the questions; it changes the person.

FAQ
Questions, answered.
How is this different from scripted roleplay tools?
There's no decision tree. The counterpart is a behavioral character, not a script — it responds to what you actually said, follows you when you change subject, and remembers your earlier claims. Two runs of the same scenario never play the same way.
What does a counterpart actually do in a call?
It behaves the way its scenario demands: stalls, objects, pushes on price, probes vague answers, warms only when you earn it — and on hard difficulty, hangs up on a weak opener.
Do I need to write a script or set anything up?
No — pick a scenario and a difficulty and start talking. If you want the counterpart to be a specific real person, paste a LinkedIn URL or website and it's researched into a persona first.
Which scenarios does the engine cover?
25+ scenarios across eight categories — selling, interviews, leadership, negotiation, customer conversations, public & media, language practice and exam prep — each with its own counterpart behavior and its own scoring rubric.
What are the voices like?
Native-quality neural voices at real conversational speed, in ten languages — with the natural hesitations, interruptions and pace of a person on the phone.
What does it cost to try?
Sign-up is free and comes with free practice minutes. No card required.
No script.Just the conversation.
Pick a scenario, pick a difficulty, and say the first word out loud. The counterpart takes it from there.
