Create AI that can grow beyond a chatbot.
Build the role, knowledge, behaviour, memory, scenarios and evaluation once. Launch standalone, connect organisational systems when needed, and deploy the same intelligence across web, LMS, API, voice, XR or embedded products.
Start standalone. Connect when ready. Embed at scale.
Build the intelligence first. Integration follows value.
From first idea to embedded intelligence
Start standalone. Connect when ready. Embed at scale.
Launch without integration
Choose a use case, add your knowledge and rules, configure behaviour and publish by private link or website embed.
Test with real people
Measure sessions, goals, scoring, feedback and usage. Refine the content and behaviour without rebuilding the application.
Connect operational systems
Add the interfaces your deployment actually needs: LMS, SSO, API, voice, CRM, HR, reporting, internal data or custom applications.
Turn SIELUNE into infrastructure
Use API, SDK, white-label or OEM deployment to include SIELUNE-powered intelligence inside another product or service.
The intelligence does not need to be rebuilt as the deployment grows.
One intelligence platform. Flexible depth.
Configure knowledge, behavior, rules, and memory once — then deploy through any surface.
Role, persona, traits, tone, voice, and explicit ethical boundaries.
Approved knowledge base, memory, structured scenarios, and scoring rubrics.
Environmental rules, multi-entity relationships, conversation phases, and world state.
Browser, standalone URL, Moodle LMS, REST API, spoken voice, or 3D/XR avatar.

Any client can do this through the business portal: create the entity, define the knowledge and rules, then deploy it as a website widget, LMS embed, Unity/XR experience or API-connected assistant. For web deployment, the portal gives them the embed snippet and the same live assistant API used by the hosted product.

Tell SIELUNE what you need
Choose a template or describe the trainer, coach, expert or character you want.
Give it your knowledge and rules
Upload documents, define role behaviour, scenario flow and evaluation criteria.
Launch it
Share a link immediately or deploy through LMS, website, API, Unity or XR.
No AI development project required.
As simple or as deep as you need.
You do not pay complexity tax when you do not need complexity. SIELUNE activates the capabilities required by each use case.
Role + scenario + scoring
One session. Fast setup. Immediate practice and feedback.
Knowledge + behaviour rules
Add company documents, constraints and role behaviour for higher realism.
Memory + relationship
Remembers the person and previous sessions over time.
Goals + emotion + autonomy
Multi-entity worlds, long-term simulations and XR-native experiences.
One message, as much depth as you choose
Full pipeline: 3–10 seconds, 40+ steps. Every entity remembers, feels and evolves across sessions.
What users feel: faster feedback, deeper realism, fewer bottlenecks
Same platform. Completely different AI.
Start with the exact depth your use case needs, then expand without changing platforms.

Separately, the wider Virtual Dawn team has delivered more than 50 interactive applications across training, education and simulation since 2017.
What it actually looks like

The chat, mid-conversation
Same widget as the live demo above — a real reply, with real timing.

The builder, behind the login
Where you create, publish and manage every entity — this is what your team gets.
Aurora as a talking avatar
The same entity can also inhabit a live video presence. On this page, Aurora is a proof of embodiment and deployment, not an investor-style interview bot. The point is to show that a client can build one soul and place it into a video avatar, a website assistant, or another interface.
The same entity, inside real environments
Entity customization and scenario showcase — the same avatar system used across healthcare, industrial and training deployments.
Field technician using a tablet-connected entity to help debug machinery — the industrial/enterprise use case.
Multiple NPCs, each with their own look and voice — customise every entity to fit your world.
What institutions say
Simulations enabled teacher students to practise and reflect on managing emotionally challenging classroom interactions and to reflect on their professional identity and pedagogical principles.
Working with Virtual Dawn is easy and customer service is top of the industry. Their tools make it easy to work with the content and it empowers the end users without calling the developers all the time.
We have used their tools in multiple projects and it has been a great experience even with more experimental projects.
Virtual Dawn gave an awesome basis for a project. Their player-object had fitting controllers for interaction that gave us a great advantage especially when it comes to creating a VR app fast that has demanding features.

Book a demoAll prices shown are net prices. VAT is added at checkout where applicable.
SIELUNE charges per AI interaction — one learner message and one AI response, with memory retrieval, scenario state, evaluation logic and the reply included. Pricing is organisation-level rather than per learner seat: you pay for usage volume, not headcount.
One interaction = one exchange (learner message + AI response with memory, scenario state, evaluation and reply). A complete training session typically uses 10–20 interactions, so €0.09/interaction equals approx. €0.90–€1.80 per full session. The listed packs are already bulk-discounted tiers (€0.09 each at 10k, €0.08 each at 50k). Annual institutional licences include an agreed pooled usage volume, and larger prepaid volumes can be priced as custom blended contracts.
Start small. Expand as training grows.
One pricing model across all use cases: same interaction economics, different capacity tiers.
Every plan includes a monthly interaction allowance. Add learners, scenarios and integrations as your organisation expands its use.
