How it works

Four parts. One practice.

No script. No menus. A real conversation with an adaptive AI avatar - followed by feedback scored against a validated behavioural rubric, not generic commentary.

See the step-by-step methodology
01

Real-life avatars

Speak with avatars built on validated behavioural models - they respond to what you say as a real counterpart would.

02

Adaptive scenarios

Every conversation adapts in real time to the learner's choices, calibrated to difficulty and role by our learning scientists.

03

Validated feedback

Each session is scored against a rubric co-designed with certified psychologists - the diagnostic insight is our core USP, not an afterthought.

04

Measurable confidence

Track skill gain across sessions with objective metrics your L&D team can report on and benchmark across cohorts.

The feedback engine · our core USP

The conversation is the practice.
The feedback is the proof.

Anyone can generate a chatbot. Our advantage is what happens after you speak: a diagnostic, validated assessment of how you performed in the conversation based on the objectives and performance criteria. 

01

Certified psychologists

Our rubrics are co-authored with registered organisational psychologists. Feedback is grounded in validated behavioural frameworks - not generic LLM commentary.

02

Purpose-built AI

A scoring model trained specifically for interpersonal communication assesses empathy, clarity, structure and impact across every exchange.

03

Bring your own skillset

In the admin console, you can choose your own objectives and performance indicators. Our technology allows you to measure what matters for you.
