Describe the case. Get a review-ready scenario in minutes.
SimComposer writes the whole package: objectives, patient profile, a state-based timeline with vitals, critical actions, SBAR handover, prebrief, debrief plan, rubric, equipment list and citations. All of it checked against the latest professional guidelines and aligned with industry standard best practices including INACSL and ASPiH.
Built on clinical expertise. Refined by educators.
Browser-based. No installation, no specialist hardware, no prompt engineering.

You need more scenarios than you have time to write.
And the ones you do write age the moment a guideline changes.
Authoring eats teaching time
“We simply don't have the time to create scenarios.”
The most common answer we hear from sim leads. Writing lands on evenings and weekends, and every hour of it is an hour not spent teaching.
Validation fatigue
Working out what best practice says, then checking your scenario against it, is slow manual work. Legacy tools leave it to you. Generic AI does not attempt it at all.
Material goes stale
Clinical guidelines move. Canned courses go out of date the day they do, and a library scattered across drives and cloud folders in incompatible formats is hard to keep current.
Two ways in. One structured scenario out.
Guided authoring
A step-by-step wizard through the simulation design framework. Every decision explained, with the standard behind it cited.
Conversational authoring
Describe the case in plain language and refine it in conversation. Say “make the patient 45” and the vitals, presentation and labs follow.
Describe
Your idea, or one of the generated suggestions if you are staring at a blank page.
Generate
The full scenario package, typically in under four minutes.
Review & edit
Structure and standards checks run automatically. You review, change anything, regenerate or edit.
Run
Export to REALITi 360, Immersive Studio or a facilitator PDF. Nothing to reformat.

Automated clinical realism, without the validation fatigue.
Every scenario is checked before you see it, and checked again every time you regenerate.
Against the protocols
Content is checked against clinical protocols including ERC and AHA, and against simulation design standards from INACSL and ASPiH.
Against your sources
Source alignment checks that what the scenario claims matches the literature and the protocols it was built from — including the documents you uploaded yourself.
Against itself
Coherence checks catch a timeline that contradicts its own vitals, a critical action with no trigger, or a drug dose that does not match the patient.
The checks narrow down what you have to look for. They do not replace your judgement. Educator review is built into the workflow, every scenario stays fully editable, and the person carrying the clinical risk is the one who signs it off.
Not text. A scenario.
Every generation produces the components below, structured and linked to each other.
Patient imagery is realistic but fictitious, and comes with personality and behaviour notes for standardised patient work.


Nothing is locked.
Every field is yours — the overview, the patient, the tags, the duration, the timeline and each individual state. Reorder states, add events, rewrite a critical action. The interface flags what is still missing rather than quietly filling it in.
Ask for changes in conversation and the rest follows — change the patient's age and the vitals, presentation and labs update with it.
- Scenario logic as a visual flow graph, with critical actions shown at states and connections
- Ethnicity and demographic prompts surfaced as EDI decisions, not silent defaults
- Debriefing framework chosen by you — PEARLS, Debriefing with Good Judgment or GAS

Bring your own protocols and guidelines.
Drag in your PDFs and SimComposer reads them properly — the tables and the diagrams, not just the text it can scrape off the page. Local, regional, national and institutional guidance all work.
Scenarios are then generated and checked against your material alongside the international standards.
- Maintain a shared source library for the whole organisation
- Share scenarios, protocols and guidelines with colleagues
- Automatic MeSH or SNOMED tagging makes the library searchable and auditable

It arrives ready for simulation.
Quality scenarios every time, in a format the software already understands.
- Available now

REALITi 360
Exports as JSON that populates vitals and checklists directly in the app. The scenario opens ready to run on the patient monitor.
- Growing support

Immersive Studio
Scenario states become scenes, with backgrounds drawn from the library and hotspots already placed.
- Available now
Facilitator PDF
Carries lab reports and facilitator checklists — the format that works for oral, tabletop and low-tech delivery.
Work in the language you teach in.
Interface and generated output both. A French user sees SimComposer in French and produces scenarios in French, across the whole authoring flow.
