D-ID is not only a real-time avatar platform.
Its AI video generator turns scripts and existing content into presenter-led videos with realistic avatars, natural voices, customizable scenes, and multilingual output.
D-ID’s V4 Expressive Avatars can be used across scripted video and interactive experiences, helping teams maintain a consistent digital presence as use cases expand.

- Create video from scripts and existing content
- Choose stock or custom presenters
- Use V4 Expressive Avatars for more nuanced delivery
- Change scripts, voices, scenes, presenters, and languages without reshooting
- Create content in 120+ languages and accents
- Automate video creation through APIs
- Extend selected videos into Agentic Video experiences
Turn video from playback into conversation
Interactive video can mean different things.
HeyGen provides structured interactive functionality including quizzes, links, branching, SCORM export, and LMS integrations on its Business plan.
D-ID Agentic Video takes a different approach: viewers can ask open-ended questions about what they are watching instead of relying only on interactions defined in advance.
Explore Agentic VideoWith Agentic Video, the viewer can start a voice or chat conversation at any point. The accompanying AI Avatar Agent is grounded in the video’s content and can be extended with additional knowledge, instructions, voice, and tools. Once the conversation ends, the viewer returns to the video.
This makes Agentic Video particularly useful for training, product education, sales enablement, and other situations where the next question depends on the individual viewer.
D-ID AI Avatar Agents vs HeyGen LiveAvatar
Both platforms support real-time avatar conversations.
D-ID AI Avatar Agents
D-ID AI Avatar Agents combine expressive real-time avatars with conversational AI. They can work with LLMs, connected knowledge, configurable instructions, APIs, and applications.
Connect the avatar to your AI stack
D-ID’s real-time platform can support:
- Custom or supported LLMs
- RAG-based company knowledge
- Agent instructions and behavior
- Websites and applications
- APIs and SDKs
- Conversation data
HeyGen LiveAvatar
HeyGen’s LiveAvatar is designed for live interaction and supports API and SDK integration. HeyGen describes it as a separate platform from its main video product, with its own plans and settings. Standard HeyGen video avatars and LiveAvatars are currently not cross-compatible.
This means the avatar can become the human-facing interface of an AI system rather than simply its visual output.
Typical applications include virtual tutors, product experts, roleplay partners, customer-facing representatives, and conversational access to internal knowledge.
For companies expecting their avatar use cases to expand from content creation toward real-time interaction, the architecture behind the avatar becomes an important part of the decision.
Explore AI Avatar AgentsBuilt for real-time conversations
Once an avatar becomes conversational, visual quality is only part of the experience. Speech and mouth movement need to remain synchronized, facial behavior needs to feel appropriate, and responses need to arrive quickly enough for the interaction to feel natural.
D-ID currently reports for V4:
- Context-sensitive facial expressions
- Multiple sentiments with EQ-based control
- Up to 4K output

Real-time lip-sync benchmark, June 2026
D-ID compared real-time avatar streaming from D-ID, HeyGen, Anam, and Tavus using SyncNet, an academic benchmark for measuring synchronization between speech audio and mouth movement.
| Platform | Rank | LSE-D, lower is better | LSE-C, higher is better |
|---|---|---|---|
| D-ID | #1 | 7.16 | 8.67 |
| Anam | #2 | 7.84 | 8.20 |
| HeyGen | #3 | 7.93 | 7.29 |
| Tavus | #4 | 8.42 | 6.33 |
Lower LSE-D and higher LSE-C indicate better audio-visual synchronization. Result: D-ID ranked first on both measured SyncNet metrics. The benchmark used five avatars per provider, varied scripts, real-world network conditions, hundreds of videos, and tens of thousands of frames, measured with the SyncNet reference implementation.

For organizations with strict data, latency, residency, or infrastructure requirements, a standard hosted service is not always enough.
D-ID’s Self-Hosted Expressive Avatars can run inside customer-controlled infrastructure, including AWS, Azure, Google Cloud, private networks, and VPC environments.
D-ID also supports customer-selected speech, LLM, and voice providers in self-hosted configurations.
Explore self-hosted Expressive AvatarsThis gives enterprises more control over:
- Data residency
- Network architecture
- AI providers
- Latency
- Scale
- Security and compliance
Enterprise security and governance
Both D-ID and HeyGen provide substantial enterprise security capabilities.
D-ID maintains SOC 2 alongside certifications including:
HeyGen publicly documents enterprise features including SOC 2 Type II, SSO, SCIM, access controls, MFA, and additional governance functionality. Its exact capabilities vary by plan.
- SOC 2Service organization controls
- ISO/IEC 27001Information security management
- ISO/IEC 27017Cloud security
- ISO/IEC 27018Protection of personally identifiable information in cloud environments
- ISO/IEC 42001AI management systems
- ISO/IEC 27799Health information security
For enterprise buyers, the relevant question is which combination of security controls, certifications, deployment architecture, and data requirements matches the intended use case.
D-ID’s option to run real-time avatar technology inside customer-controlled infrastructure adds another layer of flexibility when those requirements are strict.

AI avatars don’t have to stop when the video ends
AI avatars have already changed how quickly organizations can create and update video. But video does not have to be the end of the experience.
D-ID lets teams create scripted AI video, let audiences interact with that content through Agentic Video, or give users a real-time AI Avatar Agent they can speak with directly.
