Dorthi AI, an AI digital twin platform There's One of You. Now There Can Be Many

Dorthi AI is a personalized AI digital twin platform we designed and engineered for a client in the creator economy. It captures a person’s likeness, voice and expertise, then generates video and answers on demand, 24/7, in any language.

Free 30 minute build call. Architecture, timeline and cost, no obligation.

Client: Confidential, under NDA
Industry: Creator economy, media
Product: AI digital twin platform
Platform: Web app, REST API
Our role: Discovery to launch, ongoing support
Status: Pilot

Unmistakably You

The person's likeness, voice and expertise, captured faithfully. Not a generic stock avatar.

Always On

Present 24/7, in any language, in many places at once, without being in the room.

Minutes, Not Shoots

New videos and interactions generated on demand. No camera, no crew, no retakes.

The challenge

One Person's Time Doesn't Scale. Their Presence Can

Our client came to us with a simple problem. Experts and creators are limited by the hours in a day, and every new video still needs a full production.

A Personal Brand Caps Out

Reach stops at the number of hours in the day.
Filming Content Is Slow

Every video means script, shoot, edit and repeat.
Expertise Stays Locked to One Person

It can't be in two places or two time zones at once.
Personalization at Scale Is Impossible by Hand

Tailored messages go out one at a time.

your twin, always on

Your presence, multiplied.

What we built

A Twin That Looks, Sounds and Thinks Like You

Four capabilities working as one platform, from a short capture session to content generated on demand.

Lifelike Avatar

An AI twin that looks and moves like you, trained from a short capture session.

Your Voice, Cloned

Natural speech in your own voice, from any script and in other languages.

Knowledge Grounded

Trained on your content, so the twin speaks with your real expertise, not guesses.

Generate on Demand

New videos, messages and interactions in minutes, whenever you need them.

Our role

One Team, From Idea to Live Product

Ailoitte owned the full build for our client, so there was a single team accountable for the product.

Product discovery Use cases, scope and model selection
UX and UI design Capture flow, studio and generation screens
AI engineering Avatar, voice, persona and RAG pipeline
Platform engineering API, media pipeline and render orchestration
Cloud, QA and support GPU infrastructure, QA and testing, and ongoing care

How the Build Ran

Discovery Weeks 1 to 2. Scope, architecture and model choices locked.
Design Weeks 3 to 5. Capture, studio and playback flows.
MVP build Weeks 6 to 14. Twin engine and media pipeline working end to end.
Pilot and scale Week 15 onward. Pilot users, monitoring and ongoing support.

FAQ

What Teams Ask Us First

What is Dorthi AI?

Dorthi AI is a personalized AI digital twin platform. It captures a person’s likeness, voice and expertise, then generates video and answers on demand, around the clock and in any language. It combines avatar synthesis, voice cloning and a large language model grounded in the person’s own knowledge. Ailoitte designed and engineered it as part of our generative AI development work.

Who built Dorthi AI?

Ailoitte designed and engineered Dorthi AI for a client in the creator economy, under the Ailoitte Excellence Program. The client’s name stays confidential under NDA. Our team covered product discovery, UI/UX design, AI engineering, the media pipeline and cloud infrastructure. You can see the other products in the program at Ailoitte Labs.

Can you build a digital twin or AI avatar product for us?

Yes. Dorthi shows the pattern, and we adapt the avatar, voice and persona to your use case. That could be a personal brand, a customer-facing presenter, sales outreach, training or support. If you want the twin to take actions as well as talk, we add AI agents on top, and for text-first experiences we start from AI chatbot development.

How much capture data does an AI twin need?

A short capture session is usually enough to train a lifelike avatar and clone a voice. The exact length, recording setup and fidelity depend on the synthesis and voice models chosen, which we confirm with you during discovery.

How does the twin stay accurate to my expertise?

The twin answers from your own content using retrieval augmented generation (RAG). Your documents, talks and materials sit in a vector store, and the model pulls from them before it responds, so answers stay grounded in what you actually said. We explain the method in how RAG is transforming enterprise AI.

How long does it take to build a product like this?

We start with a focused AI strategic discovery to lock scope and architecture, then build a working MVP, typically within a few months. Scope, timeline and cost are agreed before build starts. Our MVP development page shows how we get to a first release.

Who owns the IP and the code?

You do. The codebase, integrations and architecture belong to you, with no vendor lock-in. Where third-party synthesis or voice models are used, we make their licensing terms clear before you commit.

How do you handle consent and misuse of someone's likeness?

On builds like this, consent comes first. We verify that the person being captured has agreed, restrict who can generate content from a twin, keep an audit log of what was generated, and support labeling or watermarking of AI-generated media. We also align the build with rules such as the EU AI Act and GDPR.

Tell Us What You Are Building

One 30 minute call, then a technical plan and an exact price with a fixed scope and a date. A team that has shipped an AI digital twin platform should also tell you when you do not need a custom build. If an off the shelf model would serve you better, we will say so on that call.
