Live AI avatar
A face and a voice
for your website.
Defne greets your visitors, listens, and answers out loud from what you've taught it, in real time. Made from a single photo, added with a single line of code.
Nothing listens until you press Start. Tested in English and Turkish.
From idea to talking avatar in five steps
- 1
Choose a character
Start from a ready-made avatar or upload a clear, front-facing photo you have the right to use.
- 2
Customize
Name, role, greeting, voice, language and how it should talk.
- 3
Add knowledge
Paste your FAQs, hours and policies. Defne answers from them and says when it doesn't know.
- 4
Preview
Talk to your draft in Studio before anyone else can.
- 5
Embed
Copy one script tag. Approve the websites that may use it, and change them any time.
One photo becomes a live face
Defne finds the landmarks of a face in your photo and animates it right in the visitor's browser: jaw, lips and blinks follow the voice as it speaks. It's an animated photograph, not a deepfake video or a 3D scan, so it stays light and private. The photo never leaves Defne's own storage.
Real conversation, not a phone tree
Visitors speak naturally and can interrupt at any time. A realtime speech-to-speech model hears them and answers in its own voice, without a text-to-speech relay, and the avatar's mouth moves with that audio. Prefer typing? That works too, with captions throughout.
One snippet, any site you approve
<script src="https://defne.ceylan.world/embed.js"
data-project="prj_…" async></script>Works anywhere you can add a script: plain HTML, WordPress, Shopify, Webflow, React. Move to a new domain by approving it in Studio; the snippet stays the same.
Honest by design
- Always introduced as an AI avatar.
- No microphone, camera or sound before the visitor chooses to start.
- No recordings and no stored transcripts by default.
- Photo avatars require the owner to confirm they have consent to use that face.
