Digital twins are no longer limited to engineering, manufacturing or large industrial systems. Businesses are now using digital twin technology to improve operations, create content, train employees, support customers and communicate across multiple languages.
A digital twin can represent a physical object, a business process or even a person. When combined with artificial intelligence, it can analyse information, predict outcomes, generate content and interact with customers.
This guide explains what digital twins are, how they work and the most valuable digital twin use cases for modern businesses.
TLDR: How are digital twins used in business?
A digital twin is a virtual representation of a real object, system, process or person.
Businesses use digital twins to:
- Scale content without requiring constant filming or recording
- Simulate operations before making real-world changes
- Monitor equipment and predict maintenance requirements
- Create realistic AI avatars for videos and presentations
- Produce multilingual marketing and training content
- Improve customer support and website experiences
- Deliver consistent sales presentations
- Automate repetitive communication
For example, a manufacturer might use a digital twin to monitor machinery, while a service business might use a high-fidelity digital twin of its founder to produce videos, explain services and communicate in multiple languages.
What is a digital twin?
A digital twin is a digital version of something that exists in the physical world.
It can represent:
- A machine or piece of equipment
- A building or physical environment
- A supply chain
- A customer journey
- A business process
- An individual person
The digital version uses data to reproduce or model the behaviour, appearance or performance of its real-world counterpart.
Traditional digital twins are commonly associated with engineering and manufacturing. However, advances in artificial intelligence have expanded the technology into areas such as marketing, training, customer service, video production and multilingual communication.
A human digital twin, for example, can recreate a person’s appearance, voice and presentation style so they can produce content without recording every individual video manually.
Is a digital twin the same as artificial intelligence?
A digital twin and artificial intelligence are related, but they are not exactly the same.
A digital twin is the virtual representation itself. Artificial intelligence can be added to make that representation more intelligent, responsive and useful.
AI may be used within a digital twin to:
- Analyse large amounts of data
- Recognise patterns
- Predict future behaviour
- Generate speech or video
- Respond to questions
- Translate content
- Automate decisions or actions
For example, a basic digital model of a machine may display its current operating status. An AI-powered digital twin could go further by identifying unusual behaviour and predicting when the machine is likely to require maintenance.
Similarly, a video avatar may visually represent a person. When combined with voice cloning, language processing and automation, it becomes a more capable human digital twin.
Digital twin types compared
| Type of digital twin | What it represents | Common business uses | Main benefit |
|---|---|---|---|
| Product digital twin | A product, machine or individual asset | Testing, monitoring and maintenance | Improves product performance |
| Process digital twin | A workflow or operational process | Process testing and efficiency improvements | Reduces disruption and wasted resources |
| System digital twin | A connected group of assets or processes | Supply chains, energy systems and facilities | Provides a wider operational view |
| Customer digital twin | A model of customer behaviour or journeys | Personalisation and customer experience planning | Helps businesses understand customer needs |
| Human digital twin | A digital representation of a person | Videos, training, sales and multilingual communication | Scales a person’s presence and knowledge |
The right option depends on whether the business is trying to improve physical operations, understand customers or scale communication.
Seven valuable digital twin use cases for businesses
1. Operations and process optimisation
Businesses can use digital twins to model how a system or process works before making changes in the real world.
This allows teams to test different scenarios without disrupting live operations.
Examples include:
- Modelling a production line before changing its layout
- Testing staffing levels before changing employee schedules
- Identifying bottlenecks within a supply chain
- Simulating changes to energy usage
- Improving delivery routes and logistics
- Testing a new customer journey before launching it
A digital twin provides a controlled environment in which businesses can identify risks, compare options and make more informed decisions.
2. Predictive maintenance
Digital twins can help businesses monitor equipment and identify signs of wear or unusual performance.
Instead of waiting for equipment to fail, a company can use real-time and historical data to estimate when maintenance may be required.
This can help:
- Reduce unplanned downtime
- Extend the usable life of equipment
- Improve maintenance scheduling
- Prevent expensive failures
- Reduce unnecessary inspections
Predictive maintenance is particularly valuable in manufacturing, transport, construction, utilities and energy.
3. Customer service and website support
Digital twins can also support customer-facing experiences.
A business can combine a human digital twin with an AI chatbot to create a more engaging way for visitors to ask questions, understand services or find relevant information.
Potential uses include:
- Answering frequently asked questions
- Explaining complicated services
- Guiding visitors towards the right product
- Providing personalised recommendations
- Supporting customers outside normal working hours
- Presenting information through a recognisable spokesperson
The chatbot handles the conversation, while the digital twin can provide a more human and visually engaging presentation.
Businesses should still make it clear when a visitor is interacting with AI and provide access to a human when necessary.
4. AI avatars for business communication
A human digital twin can act as a consistent digital spokesperson for a company.
An AI avatar can be used to:
- Introduce a business
- Explain products and services
- Present company updates
- Deliver marketing messages
- Create social media videos
- Record internal announcements
- Present educational content
This is particularly useful for founders, subject-matter experts, trainers and sales professionals who need to communicate regularly but cannot continually record new videos.
Nertia’s digital twin service combines visual avatars, voice modelling and multilingual video production to help businesses create a scalable digital presence.
5. Video production at scale
Traditional video production can require scripts, filming, equipment, editing and repeated recording sessions.
A digital twin can simplify this process by allowing approved scripts to be turned into presenter-led videos without requiring the original person to appear on camera each time.
Businesses can use digital twins to create:
- Social media videos
- Product demonstrations
- Website explainers
- Training content
- Educational videos
- Sales presentations
- Internal communications
- Customer onboarding guides
The biggest advantage is not simply speed. It is the ability to produce consistent content while reducing the amount of time key team members spend filming.
6. Voice cloning and multilingual communication
Voice cloning creates a digital model of a person’s voice, including elements such as tone, pace and rhythm.
Once created with the person’s consent, the voice can be used for:
- Video narration
- Product walkthroughs
- Internal training
- Audio guides
- Presentations
- Multilingual video dubbing
- Marketing content
A digital twin can also present translated content while retaining a recognisable voice and on-screen identity.
This can help businesses communicate in new markets without recording each language version separately.
The technology should always be used with clear permission, secure access controls and agreed limits around how the digital identity may be used.
7. Sales, onboarding and training
Digital twins can deliver repeatable information consistently across sales, customer onboarding and employee training.
Examples include:
- A founder presenting an introductory sales video
- A product expert explaining software features
- A trainer delivering employee onboarding modules
- A consultant answering common client questions
- A virtual presenter demonstrating a service
- A digital spokesperson explaining company policies
Digital twins can deliver the same approved message each time, while employees remain available for conversations that require judgement, empathy or personal attention.
Real-world digital twin applications by industry
Manufacturing
Manufacturers can create digital versions of machines, production lines or entire facilities.
These models can be used to monitor performance, identify inefficiencies and test changes before applying them to physical equipment.
Retail and ecommerce
Retail businesses can use digital twins to understand customer journeys, model stock movement and create AI-powered product content.
Human digital twins can also present product demonstrations, buying guides and personalised video messages.
SaaS and technology
Software companies can use digital twins for:
- Product demonstrations
- Feature walkthroughs
- Customer onboarding
- Help-centre videos
- Employee training
- Multilingual product education
A well-designed business website can bring these resources together and help customers access the right information at each stage of their journey.
Professional services
Consultants, agencies, coaches and advisers can use digital twins to explain their expertise at scale.
A digital version of a subject-matter expert could present introductory videos, answer common questions or deliver educational resources without replacing direct access to the real person.
Healthcare and education
Digital twins can be used to model systems, communicate information and create repeatable training content.
Applications involving sensitive personal or medical data require particularly strong privacy, security and governance controls.
Property and construction
Property and construction companies can create digital models of buildings, sites and infrastructure.
These models may support planning, monitoring, maintenance and collaboration between project teams.
Human digital twins can also be used to create safety briefings, customer guides and project updates.
Media and content production
Creators, media businesses and marketing teams can use digital twins to produce presenter-led content more efficiently.
This can be particularly valuable when producing frequent videos, multiple variations or content in several languages.
Digital twins vs AI avatars vs chatbots
These technologies often work together, but they solve different problems.
| Technology | Main purpose | Best suited to | Typical interaction |
|---|---|---|---|
| Digital twin | Represents a physical object, process, system or person | Operations, simulation, communication and content | Can be passive or interactive |
| AI avatar | Visually represents a person or character | Videos, presentations and digital spokespeople | Mainly visual and spoken |
| AI chatbot | Holds text or voice conversations | Customer support, lead generation and website guidance | Interactive and conversational |
| Voice clone | Recreates a person’s voice | Narration, dubbing and audio content | Spoken output |
| Traditional video | Captures a person during a recording | High-value campaigns and personal communication | Pre-recorded and fixed |
A business does not always need to choose only one.
For example, a website could combine:
- An AI chatbot that answers questions
- A digital twin that presents important information
- A professionally designed business website that guides visitors towards an enquiry
The strongest setup is the one that matches the customer journey rather than adding technology without a clear purpose.
Benefits of digital twins for business
Greater scalability
A digital twin can communicate, present or support a process without being restricted by one person’s location or availability.
More consistent communication
Approved scripts, messages and training materials can be delivered consistently across different platforms and audiences.
Reduced repetitive work
Digital twins can take on repeatable communication and monitoring tasks, allowing employees to focus on work requiring personal judgement.
Faster content production
Businesses can create new video or audio content without organising a complete recording session for every update.
Improved decision-making
Operational digital twins allow businesses to test ideas and assess potential outcomes before making physical changes.
Wider international reach
Multilingual dubbing and translated content can help businesses communicate with customers, employees and partners in different markets.
Better customer experiences
Digital twins, websites and chatbots can work together to make important information easier to understand and access.
Challenges and risks to consider
Digital twins can create significant value, but they must be implemented responsibly.
Data privacy
Digital twins may rely on business, customer, employee or operational data. Companies should understand what data is being collected, where it is stored and who can access it.
Consent and identity protection
A human digital twin should only be created and used with clear permission from the person being represented.
The intended uses, ownership, access and limitations should be agreed before production begins.
Security
Voice models, avatar files, recordings and training data should be protected against unauthorised use.
Businesses should consider account permissions, secure storage and approval processes for newly generated content.
Accuracy
An AI-powered digital twin may produce incorrect information when connected to an unreliable or outdated knowledge source.
Content should be reviewed regularly, particularly when it relates to pricing, policies, legal information or technical guidance.
Quality and credibility
A poor-quality avatar or unnatural voice can reduce trust rather than improve it.
Businesses should prioritise clarity, accurate representation and professional production over novelty.
Human oversight
Digital twins should support employees rather than automatically replacing human involvement in sensitive or complex situations.
Businesses should define when a customer, employee or stakeholder needs access to a real person.

How to introduce a digital twin into your business
A digital twin project should begin with one specific, measurable use case.
A sensible implementation process is:
Step 1: Identify a repeated task
Look for an activity that takes significant time or needs to be delivered consistently, such as product explainers, training videos or equipment monitoring.
Step 2: Choose the right type of digital twin
Decide whether you need an operational model, a customer model or a human digital twin.
Step 3: Establish permissions and governance
Define who owns the data, who can create outputs and how the digital twin may be used.
Step 4: Create a small pilot
Test the digital twin on one process, audience or content type before expanding its use.
Step 5: Measure the outcome
Track results such as:
- Time saved
- Content output
- Customer engagement
- Support demand
- Training completion
- Operational downtime
- Conversion rates
Step 6: Refine and expand
Use the pilot results to improve the digital twin before introducing it into additional areas of the business.
The future of digital twins in business
Digital twins are likely to become more interactive and more closely connected to everyday business systems.
Future developments may include:
- Real-time digital humans that can hold natural conversations
- More accurate voice and visual models
- Deeper integration with CRM and support platforms
- More personalised customer journeys
- Automated multilingual communication
- Better operational predictions
- Stronger identity protection and content controls
The greatest value will come from using digital twins to solve specific business problems rather than adopting the technology simply because it is new.
