Personalized AI Avatar · Digital Twin

There's one of you. Now there can be many.

Dorthi AI is a digital-twin platform we built — a personalized AI avatar that looks, sounds and scales like you, grounded in your own knowledge and generating new content on demand. Here's how it works, the architecture behind it, and how we'd build one like it for you.

INPUT · YOUOUTPUT · EVERYWHERE

Unmistakably you

Your likeness, your voice and your expertise — captured faithfully, not a generic stand-in.

Always on

Your presence available 24/7, in any language, everywhere at once — without you in the room.

Minutes, not shoots

New videos and interactions generated on demand — no camera, no crew, no re-takes.

What it solves

You can't be everywhere — your time doesn't scale.

✕
A personal brand caps outAt the number of hours in your day.
✕
Filming content is slowEvery video is a production — script, shoot, edit, repeat.
✕
Expertise stays locked to youIt can't be in two places, or two time zones, at once.
✕
Personalization at scale is impossibleBy hand — one tailored message at a time.

your twin, always on

Your presence, multiplied.

How it solves it

A twin that looks, sounds and thinks like you.

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

Lifelike avatar

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

Your voice, cloned

Natural speech in your own voice, in any script — and, if you want, any language.

Knowledge-grounded

Trained on your content and materials, so the twin speaks with your actual expertise.

Generate on demand

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

Capture

Likeness & voice.

Train

Your twin.

Ground

In your knowledge.

Script

What to say.

Generate

Video on demand.

Under the hood

An architecture built for generative presence.

Dorthi pairs an avatar and voice engine with a knowledge-grounded persona, orchestrated through a media pipeline that renders on demand. Reference architecture — synthesis & voice pipeline confirmed per build.

Built & run by Ailoitte

We built a digital twin. Let's build yours.

Dorthi is one of several enterprise AI products we've designed, engineered and operate. Whether it's avatars, generative media or any AI-native experience, the same team and architecture playbook build your platform — with full IP ownership and zero lock-in.

Talk to the team that built this

For your build

What teams ask us first.

Yes — that's exactly what we do. Dorthi shows the pattern; we adapt the avatar, voice and persona to your use case, whether that's a personal brand, customer-facing presenter, training or sales.

A short capture session is enough to train a lifelike avatar and clone the voice. The exact fidelity, controls and use cases are something we scope with you in discovery, along with the synthesis and voice models that best fit.

We start with a focused discovery to lock scope and architecture, then build a working MVP — typically inside a few months. Scope, timeline and cost are clear before we start.

Fully. The codebase, the integrations and the architecture are yours — no vendor lock-in. Where third-party synthesis or voice models are involved, we make their licensing fully transparent.
