Duix
Duix is a conversational AI platform that replaces text chatbots with real-time video avatars that have a face and a voice. It offers stock and cloned characters, 50+ spoken languages, and API access on every plan, including the free one.
What is Duix?
Duix is a platform for conversational AI avatars, or digital humans: characters that hold a live video conversation with a face, a voice and a degree of visual awareness. The pitch is explicitly a departure from the text chatbot. The homepage claims 200 ms time to first byte, a 1:1 likeness between the avatar and its reference, and genuine two-way real-time interaction rather than a pre-rendered clip.
Three capabilities are put forward. Realism covers lip-sync, facial rendering and body motion. Flexible integration covers the SDKs and the API, with customisation of avatars, voices, personas and conversation logic. Vision covers recognition of faces, gestures, emotions and environmental context, which is what separates this from a voice bot with a picture attached.
The site frames the product through six roles: AI doctor, AI customer service, AI interview, AI girlfriend, AI boyfriend and School AI. The same engine is sold to a support team, a recruiter, a teacher and someone looking for company, which is a wide span for one product.
Building an avatar takes three documented steps. First its appearance, chosen from a library of realistic characters or produced on request. Second its soul: uploaded documents, connected APIs and a defined personality, which together form what Duix calls its brain. Third going live, either in a hosted conversation or embedded through the API. Voice cloning is available from an upload or a recording of at least ten seconds, with the user asked to confirm they hold the rights to the sample.
On the technical side, Duix claims more than 50 languages for understanding and speech, streams at 1080p on every tier, and caps the number of concurrent conversation streams per plan. Billing runs on conversation minutes: an account needs available minutes before a session opens, through the web app or the API alike. Notably, the API is open on every plan, including the free one, and the documentation warns that generation is non-deterministic, so identical settings can still produce slightly different results.
What it does

- Pick a character from the stock library or create a personal avatar, within a monthly quota
- Clone a voice from an uploaded file or a short recording
- Feed the avatar documents and connect APIs to shape its knowledge and personality
- Embed the avatar into a website or an app through the API and the SDK
- Manage API keys, conversations and avatars from the developer portal
When to use Duix / When not to
A quick filter to help you decide if Duix is the right fit.
When to use Duix
- Support teams that want a video agent able to answer around the clock rather than a text widget
- Recruiters running first-round interviews, where the platform promises live conversation and immediate analysis
- Teachers and instructional designers building interactive lessons around a speaking on-screen character
- Developers embedding an avatar into their own product, since the API is open on every plan and the SDK ships with sample code
- Individuals exploring companion-style uses on a personal, non-commercial licence
When not to use Duix
- Buyers who need a readable legal framework: no company entity, no postal address and no legal notice are published anywhere on the site
- Organisations bound by a GDPR review, since the site says nothing about GDPR, processing agreements, subprocessors, retention or model training
- Agencies and resellers, as the pricing FAQ itself raises white labelling as something Duix does not support
- Businesses that plan to trade on an individual tier, which carries a personal licence limited to non-commercial use
- Teams without a recurring budget, because the first paid tier starts at 29 USD per month and real usage is billed in conversation minutes
How to use Duix
A typical end-to-end flow, from setup to results.
- Create an account through Google, Apple or an email address confirmed by a PIN code
- Start from the free tier, which the site advertises as requiring no payment
- Pick an avatar from the stock library, or open the avatar creator if the plan allows personal creations
- Give the character its appearance, then its personality by uploading documents and connecting APIs
- Optionally clone a voice by uploading an audio file or reading a sample script aloud for a few seconds
- Launch a live conversation from the workspace and watch the remaining minutes counter
- For an integration, obtain a conversation ID, then the API keys, then an access token
- Call the API directly or plug in the H5 SDK, using the published React sample as a starting point
- Size the plan against expected peak usage, since concurrent streams and monthly minutes are both capped
- Contact sales for a bespoke tier when minutes, concurrency or avatar creations need to be negotiated
Pros & Cons
Pros
- Pricing is fully public and quantified, from a free tier up to 4,999 USD per month, with the matching quotas shown
- The API is included from the free plan onwards, where many competitors reserve it for paid tiers
- Developer documentation sits on its own subdomain, with an API reference, SDKs and public sample code on GitHub
- Broad language coverage is claimed, with more than 50 languages for understanding and speech
- The real-time video modality with vision goes beyond a text or voice chatbot
- The vendor claims backing from Sequoia Capital and Tencent Capital and more than 100 patents
- Paid tiers are advertised as cancellable at any time
Cons
- No legal entity is named anywhere: the only trace is a footer copyright reading DUIX
- No postal address and no legal notice are published on the site
- The terms of service and privacy policy pages exist but their content is rendered client-side and cannot be read in the served HTML
- The site is completely silent on GDPR, processing agreements, subprocessors, retention and training on customer data
- A single address, support@duix.com, handles support, sales and partnerships alike
- White labelling is not supported, a point the pricing FAQ raises itself
- Costs are driven by conversation minutes, which makes a budget hard to forecast before real usage

Data, GDPR & hosting
A consolidated view of how Duix handles your data.
GDPR overview
Duix makes no GDPR statement at all. Searching every page collected, in both rendered text and archived HTML, returns no occurrence of GDPR, of a data processing agreement, of subprocessors, of retention or of model training. This is silence rather than a refusal: the vendor never denies the regulation, it simply never addresses it. A terms of service page and a privacy policy page do exist and answer normally, but their body is injected by JavaScript and is absent from the HTML actually served, so their commitments cannot be read before signing up. No Article 27 representative is named, and no data protection contact is offered: the site exposes a single address, support@duix.com. The About page mentions a Singapore team handling compliance assurance, without naming any regime.
Hosting summary
Duix publishes no hosting information: no country, no region and no provider is declared anywhere on the site, and no commitment is made about where conversations are stored or processed. What can be established is purely technical and observed from outside. The domain resolves to 190.92.217.202, an address geolocated in Singapore and announced by AS136907, Huawei Clouds. Static assets are served from an Alibaba Cloud object storage bucket named duix-southeast through a global acceleration endpoint. The About page separately situates an international team in Singapore. None of this amounts to a contractual guarantee: an IP address can move at any time, and a team location says nothing about data residency. Anyone with a data residency requirement should treat hosting as undocumented and obtain a written answer before use.
Things to keep in mind
Risks and trade-offs to weigh before adopting Duix.
- No legal entity, postal address or legal notice is published, so there is no identified counterparty behind the service
- The terms of service and privacy policy cannot be read in the served HTML, meaning you commit without seeing the commitments
- Nothing is stated about retention, subprocessors or whether conversations are used to train models, and video conversations are unusually personal data
- Voice cloning shifts responsibility onto the user, who must confirm they hold the rights to the sample they upload
- The AI doctor use case advertises 24/7 health advice and virtual consultations with no visible medical disclaimer
- Companion characters are promoted for emotional presence with no minimum age published anywhere, and lifelike avatars invite attachment that a text bot does not
- Costs scale with conversation minutes, so an engaging avatar can quietly become the most expensive part of a workflow
Setup & Integrations
Technical difficulty
Getting started is easy: sign in with Google, Apple or an email code, pick a stock avatar and start talking in the browser, with nothing to install. Creating an avatar follows a guided three-step flow. Integration is a developer task but a well-documented one: obtain a conversation ID, then API keys, then a token, then call the API or plug in the H5 SDK, with public React sample code available. The genuine difficulty is not technical but sizing: matching concurrent streams and monthly conversation minutes to expected peak demand.

Should you pick Duix?
Duix is a real product, and that deserves saying plainly because it is not always the case in this category. The pricing grid is public and quantified across eight tiers, the API reference and SDKs sit on a dedicated documentation subdomain, sample code is published openly, and the API is available from the free plan onwards. Technically, the proposition is coherent: live video rather than text, vision on top of speech, more than 50 claimed languages, voice cloning, and billing in conversation minutes that at least maps honestly onto what the service actually costs to run.
The blind spot is just as clear. Duix publishes no legal entity, no postal address and no legal notice. Its terms of service and privacy policy exist as pages but their text is injected by JavaScript and never appears in the HTML served, so a prospective customer cannot read what they are agreeing to before creating an account. Nothing on the site addresses GDPR, processing agreements, subprocessors, retention or whether customer conversations feed model training. For an individual trying the free tier, that gap is an annoyance. For a company placing recorded video conversations with customers, candidates or patients into it, it is a blocker until answered in writing.
The sensible reading is therefore split. As a technical building block, Duix is easy to evaluate at zero cost and easy to integrate. As a supplier, it has yet to publish the basics that any procurement review asks for. Anyone considering the AI doctor or AI interview use cases should weigh this twice, since those touch health advice and hiring decisions with no visible disclaimer. Test it freely, model the cost in minutes before committing, and ask for the legal documents in writing.
