Your voice clone was removed
Welcome back. Because you did not sign in for over 14 days, we removed your voice clone to free up capacity for active users. The rest of your twin (face, handwriting, chat history, settings) is untouched.

You can re-record your voice in under a minute whenever you are ready.
Before you build your twin
buildahuman.ai creates a digital twin from a person's voice, face, handwriting, and personality. Because that is powerful, we need you to read and agree to all four points below before you continue. The links open the full document.

What you get

Everything that makes you, you.

Most clones are a face filter or a chat bot. A twin is the whole loop: your voice, your face, your turn of phrase, your handwriting, your stories.

Your voice, cloned
A 30 second sample is enough to capture timbre, cadence, accent. Your twin will sound like you, not a generic narrator.
Your face, animated
One photo is plenty. Your twin lip syncs to its replies in real time so it feels like a video call, not a text bubble.
Your way of thinking
Drop in your bio, your essays, your favourite stories. Your twin learns your worldview, your idioms, your sense of humour.
Live conversations
Talk to other people's twins or put two of them on stage together. Your twin can hold its own across topics, debates, interviews.
Your handwriting too
Upload a worksheet and your twin learns to sign, scribble, and reply with strokes that look like yours, not a font.
You stay in control
Your twin is private by default. Make it discoverable when you want. Delete it permanently any time, with one click.
How it works

Four steps. About four minutes.

Setup is short on purpose. The twin gets better the more you give it, but every step is optional after the first.

Record your voice

Read three short sentences. We clone your voice from those alone.

Snap a photo

One clear front facing shot. Your twin learns to lip sync from it.

Tell us about you

Bio, links, stories, anything. Your twin reads it and absorbs it.

Start talking

Chat one on one, or watch your twin debate someone else's.

Pricing

Start free. Upgrade when your twin gets popular.

Common questions

The honest answers.

We are deliberate about what a twin can and cannot do, and how we treat the data you give us.

Is this a deepfake tool?
No. Every twin must be of you, or of someone who has given you written consent. Twins of public figures, celebrities, politicians, or anyone you do not have permission to clone are forbidden and get removed on sight. The agreement you sign before building your twin makes this binding.
Where does my voice and photo go?
Your voice sample is sent to our voice cloning provider, and your photo is sent to our face animation provider. Your text is sent to a large language model provider to generate replies. Everything is stored under your Google account on our servers. You can wipe the whole thing at any time from the in app settings.
Can I delete my twin?
Yes. One click deletes your voice clone, photo, identity text, conversation history, and your twin's public listing. We also instruct our voice and face providers to remove the underlying assets on their side.
Is it free?
Yes, with a generous daily message budget. Voice generation and lip sync video are not cheap to run, so we cap conversations per day to keep the service free for everyone.
Do I have to be public?
No. Twins are private by default. You can chat with your own twin without anyone else seeing it. Going public is one toggle, and you can switch back any time.
How accurate are the replies?
Your twin is an AI imitation, not the real person. It will sound like you, draw from what you gave it, and stay in character, but it can be wrong, make things up, or hold opinions you would not. Treat it as expressive, not authoritative. Do not rely on a twin for medical, legal, or financial advice.

Your turn.

Sign in with Google to build your twin in about four minutes. Your data stays under your account, and you can delete the whole thing any time.

Heads up: to keep voice cloning available for everyone, we automatically remove your voice clone if you do not sign in for 14 days. You can re-record any time in under a minute, and nothing else about your twin (face, handwriting, chat history) is affected.
Step 02 of 04

Add your face

Upload a clear front-facing photo. Your twin will show your face during every conversation.

Portrait
Upload a photo of yourself
Front-facing, eyes visible, reasonably clear. Doesn't need to be professional.

Clone your handwriting

Print the worksheet, fill every box naturally, scan it. Your twin can then write anything in your handwriting.

Worksheet
Download and fill the template
151 labeled boxes covering every letter, digit, and symbol across 3 pages. Write each character naturally in the box. Don't try to write perfectly, just write how you actually write.
151 boxes3 pages a-z 3x · A-Z 2x · 0-9 1x
Don't want to clone your handwriting?
This step is optional. Your twin will still talk and look like you, it just won't write notes in your hand.
Upload Scan
Upload your completed worksheet
