What is a scenario?
Scenarios are the heart of SimChat. Each scenario sets up a simulated conversation by defining the AI character's personality, the context and the goals for the learner.
As an organisation owner or staff member, you can create scenarios and publish them for your learners to use. You can write scenarios yourself, generate them with AI, or start from one of your organisation's templates.
What a scenario is made of
- Title and description - what the scenario is about
- AI behaviour - the set of AI rules for the scenario: how the avatar plays its role, how the conversation is marked, and the style of feedback
- User instructions - what the learner reads before starting, explaining the context and objectives
- Script - the AI character's background, personality and knowledge. This is what powers the AI's responses
- Checklist - the criteria the conversation is marked against
- Questions (optional) - follow-up questions asked after the conversation
- Resources (optional) - links and a walkthrough for the learner to review afterwards
How do learners interact with a scenario?
Learners can complete scenarios in three modes, and you decide which are available on each scenario:
- Text - learners type their responses and receive text-based replies from the AI character
- Audio - learners speak with the AI character in real time. Uses audio minutes
- Video - learners talk to an AI video avatar face to face. Uses video minutes
SimChat needs no software downloads. Learners open scenarios directly in their web browser, on desktop or mobile. As long as they have an internet connection and a modern browser, it works without any additional setup.

Practice or assessment
Every scenario has a purpose that decides how it is marked and what learners see afterwards. Practice scenarios let learners self-mark and see the checklist; assessment scenarios are AI-marked and keep the marking detail from learners. See Practice and assessment scenarios.
