Duix

Duix is a conversational AI platform for interactive avatars with faces and voices. It supports Android, iOS, web, and API access. Users can customize avatar appearance and voice, choose multiple languages, connect knowledge bases, and adjust personas and conversation logic. Listed visual capabilities include lip-sync, facial rendering, body motion, and recognition of faces, gestures, emotions, and environmental context. Its use cases include AI doctor, customer service, interviews, school AI, and girlfriend or boyfriend experiences. Duix claims 200ms TTFB latency for real-time two-way interactions. Every plan, including Free, offers API access, but starting or using a session through the API requires conversation minutes in the account. Free costs nothing and includes five minutes of talk time per day, one concurrent stream, stock avatars, and no custom AI avatar support. Paid plans start at $29 a month; annual packages are not available. Duix's terms say customer content and media files may be used to provide, maintain, and improve its products and services.

Duix combines customizable interactive avatars with API access across its plans. Review the talk-time limits, custom-avatar availability, and content terms before choosing a plan.

Duix may suit developers or organizations seeking interactive avatars for customer service, interviews, education, or other listed use cases. It also supports API integration and customization of avatars, voices, personas, and conversation logic.

Duix is a conversational AI platform for creating interactive avatars with faces and voices. It suits teams building live avatar experiences into a service or application, especially when API access and language options matter. Its main trade-off is clear: broad integration features sit behind monthly talk-time caps, and useful commercial capacity starts at a substantial price.

Overview

Duix brings customizable avatars, voice, and conversation logic together for two-way interactions. Its use cases span customer service, interviews, school and AI doctor experiences, alongside personal companion applications. The platform claims 200ms TTFB latency and describes lip-sync, facial rendering, body motion, and vision capabilities for recognizing faces, gestures, emotions, and environmental context. These features suit applications that need an avatar to respond in a conversation, rather than simply produce a finished video.

Teams can connect knowledge bases, customize appearance and voice, and use SDKs or APIs to integrate avatars into applications. Every plan includes API access, including Free, but API sessions consume the account's conversation minutes. Duix says it may use customer content, media files, and interactive media to provide, maintain, and improve its services, a consideration for teams working with sensitive material.

Key features

• Interactive avatar customization: Appearance, voice, persona, and conversation logic can be tailored, while knowledge-base connections support application-specific conversations. Custom avatar creation is available on Creator Popular and above; Free and Starter do not support it.
• Multilingual presentation: Plans include support for 50+ languages and 1080p output. That combination covers a broad range of language and visual needs, though 1080p is the stated maximum resolution.
• Real-time interaction and vision: Duix describes two-way interaction, lip-sync, facial rendering, body motion, and recognition of visual cues and surroundings. The claimed 200ms TTFB is relevant to conversational use, but should be weighed alongside the monthly minutes and concurrency limits of each plan.
• Application integration: SDKs and API access are included throughout the plans. This makes it possible to build around Duix at any tier, but Free's five daily talk minutes and Starter's 150 monthly minutes sharply constrain sustained API use.

Pricing

Duix is freemium. Paid monthly plans start at $29/mo, and annual packages are not available at the moment. The plan choice is shaped by talk time, concurrent streams, custom avatar creation, and license type.

• Free — free: Includes 5 minutes of talk time per day, one concurrent stream, a personal license, API access, skill integration, 50+ languages, 1080p, and all stock AI avatars. Custom avatars are not supported. It is a useful way to explore stock-avatar conversations or build a small API proof of concept, but the daily cap leaves little room for regular service use.
• Starter — $29 a month: Raises the allowance to 150 minutes per month and keeps one concurrent stream and a personal license. It includes the same API, skill integration, language, resolution, and stock-avatar features as Free, but still excludes custom avatars. This is the lowest-cost paid option for a modest personal project; its monthly quota is too limited for a busy interactive service.
• Creator Popular — $59 a month: Provides 300 minutes per month and three personal AI avatar creations per month, while retaining one concurrent stream and a personal license. It is the first plan for buyers who need custom avatars, though the single-stream cap and personal license make it a poor fit for a commercial deployment.
• Scale — $399 a month: Adds 3,000 minutes, seven avatar creations per month, five concurrent streams, and a commercial license. It is the first listed tier suited to commercial use and offers room for several simultaneous sessions, at a sharp price increase over Creator Popular.
• Growth — $799 a month: Includes 6,500 minutes, ten avatar creations per month, 12 concurrent streams, and a commercial license. It fits a larger deployment that needs more throughput than Scale.
• Business — $1,999 a month: Expands capacity to 20,000 minutes, 20 avatar creations per month, and 20 concurrent streams, with a commercial license. It is aimed at substantial ongoing usage rather than experimentation.
• Enterprise — $4,999 a month: Includes 60,000 minutes, 50 avatar creations per month, 50 concurrent streams, a commercial license, and technical personnel support. The additional support and capacity suit the largest stated usage tier, at the highest listed fixed price.
• Customization — custom pricing: Talk time, concurrency, and personal AI avatar creation are available on demand. This is the option for requirements outside the fixed quotas.

All plans include API access, skill integration, 50+ languages, 1080p, and all stock AI avatars. The main step up for teams is not API availability but capacity and rights: custom avatars start at Creator Popular, while commercial licensing starts at Scale. Review the minute quota against expected sessions before committing, since API sessions draw from that same allowance.

Platforms

Duix is available on Android, iOS, and the web, with API access for integrations. Its platform range supports both direct use and application-based deployment.

Who it's for

Duix is a strong fit for developers and teams building conversational services that benefit from a visible, multilingual avatar, particularly when they need to connect knowledge bases or customize personas. Free is appropriate for limited exploration, and Creator Popular suits personal projects that need custom avatars. Businesses should look at Scale or higher for commercial licensing and multiple concurrent streams. Buyers seeking high monthly usage at a low entry price, or custom avatars on the cheapest tiers, should look elsewhere.

Pros and cons

• Pro: API access is included on every plan, so integration can begin without a paid subscription.
• Pro: Plans include 50+ languages, 1080p, and all stock AI avatars, providing a broad baseline across tiers.
• Pro: Custom avatars and commercial licensing are available on the plan ladder, with higher tiers adding more minutes and simultaneous streams.
• Con: Free is capped at five talk minutes per day, and Starter offers 150 minutes per month; API access does not bypass either limit.
• Con: Custom avatars are absent from Free and Starter, while a commercial license requires at least the $399 a month Scale plan.
• Con: Duix's 1080p ceiling and lack of annual packages may not suit buyers who need higher resolution or annual billing.
• Con: Duix may use customer content and media to provide, maintain, and improve its services, which may not fit every privacy requirement.

Verdict

Choose Duix if you need interactive, customizable avatars integrated into an application and can match your expected traffic to its monthly minute and concurrency limits. Its consistent API access and multilingual feature set make it a capable foundation for conversational experiences. Look elsewhere if the low tiers' usage caps are too tight, if commercial use must start below $399 a month, or if Duix's media-use terms do not fit your privacy needs.
