Create AI that can grow beyond a chatbot.
Create AI trainers, patients, coaches, experts and persistent characters — then deploy them to web, LMS, API, voice or XR.
SIELUNE is a product of Virtual Dawn · Midnight Forge Oy
Aurora — a talking video entity
What you're looking at: a SIELUNE entity with a live video face, driven by the full runtime — memory, emotion, relationship and voice — not a scripted trailer. Build one like this in the portal in about five minutes, then deploy it to your site, LMS, API or XR.
Need a website support assistant instead? Use the Taika button in the corner — that floating widget is the real embed path.
Ask anything — watch the video face and live VAD emotion state respond as the pipeline runs.
What people build on SIELUNE
Already deployed in real training and education

Unlike a disposable chatbot session, a SIELUNE entity can keep its role, knowledge, relationships, scenario state and relevant history over time.
Role + behaviour
Trainers, patients, coaches, experts — authored identity and tone.
Knowledge + rules
Approved content, constraints and organisational grounding.
Scenario + evaluation
Structured practice with goals, phases and measurable outcomes.
Persistent AI
Role, knowledge, relationships, scenario state and relevant history over time.
Multi-surface deploy
Web, LMS, API, voice or XR — same intelligence, no rebuild.
Create → Configure → Deploy → Improve
Architecture detail (Soul · Mind · World · Body, runtime, EAL) lives on How it Works.
Create the entity
Define the role — trainer, patient, coach, expert or persistent character — and the behaviour you need.
Configure knowledge & scenarios
Add knowledge, rules, scenario flow and evaluation. Keep it light for a pilot, deepen when it works.
Deploy where people are
Publish to web, LMS, API, voice or XR — same intelligence, no rebuild per channel.
Improve from real use
Measure sessions, goals and feedback. Expand persistence, integrations or OEM embedding when value is proven.
Live in three steps
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.
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.
Create a sales trainer in minutes
Create a persistent employee coach
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.
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.

SIELUNE Launch Package — €2,400 + VAT
We build your organisation a custom 3D environment and 3D character, one bespoke NPC, and include 12 months of the Starter subscription plus 1 extra NPC slot (2 slots total) — delivered as a standalone Unity app or hosted on our website, your choice. Invoiced directly, no card required.
Self-service from €99 + VAT / month
Starter on annual billing (€130/mo if paid monthly). 1 active NPC slot, 500 interactions/mo, 14-day trial. Create, configure and deploy in the portal.
Start BuildingAI Studio — €129/month
Optional add-on for any plan: describe a scenario and AI helps build the bot — knowledge, role and scenario scaffolding so you spend less time authoring by hand.
Start Building + add AI toolsSIELUNE 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.
