What is D-ID?

D-ID providesdigital personVideo and Interactivedigital persona technology company. Ordinary creators canD-ID StudioSelect a character, enter a script or audio recording, and create explanatory videos featuring facial animations and lip-syncing; businesses and developers can also use Visual Agents and APIs to enable digital avatars to respond to users’ text or voice questions based on knowledge bases. The former delivers pre-generated videos, while the latter requires a continuously running interactive service.

D-IDFounded in 2017 by co-founders Gil Perry, Sella Blondheim, and Eliran Kuta, Creative Reality Studio was launched on September 19, 2022. Initially, the company focused on generating host videos from a single image; in December of the same year, it further integrated text, images, and character animation into its generation process. In 2025, D-ID acquired the narration video platform simpleshow, continuing to expand its enterprise content production business.

Since then, the product has gradually evolved from “reading from a script” to “interacting around content.” V4 Expressive Visual Agents, released in March 2026, introduced emotional expression and real-time interaction; Agentic Videos, released in April, embedded a Q&A interface directly into the video-watching experience. It relies on specific players and interactive services; simply downloading a standard MP4 file will not provide you with a conversational agent.

Key Features

Creating Different Types of Digital Humans Using Different Materials

Digital Human Product LineClassified by source material requirements and intended use. V2 creates characters from front-facing images; V3 Instant uses short videos, retaining more of the original background and motion information; V3 Pro requires more complete footage and can process the background using a green screen; V4 Expressive uses footage featuring different emotional expressions. There are also different activation requirements for preset characters and custom characters.

Before selecting a character, you should first determine the delivery format. V3 Instant is used for video output; when real-time interaction is required, you should choose a type that supports streaming. Custom characters for businesses also involve recording, obtaining consent from the individual, and developing appropriate solutions; therefore, you should not select them based solely on the appearance of the avatar.

Studio Multi-Scene Videos

Studio combines characters, scripts, audio, and media assets into scenes. Each scene can have its own narration and visuals, and copying a scene preserves its layout. Uploaded images, GIFs, or clips can be repositioned, resized, cropped, rotated, and arranged in layers, and the volume of video clips can be adjusted individually. This allows you to break down a training topic into sequential sections—such as “background information,” “demonstration,” and “summary”—without having the presenter occupy the entire screen at all times.

Once generation is complete, you can download or share the content from the library. Pro and higher plans allow you to export standalone SRT subtitles; SRT is a subtitle file that must be embedded on the publishing platform or composited in post-production—it should not be treated as subtitles that have been burned into the video. Drafts cannot be downloaded directly as finished products.

Visual Agents Q&A

Visual AgentsUsers can configure characters, languages, voices, roles, behavioral instructions, and knowledge content, and then share them externally via links or website embeds. Knowledge can be sourced from PDF, TXT, or PPTX files, or entered directly as text. In Grounded mode, the system answers questions based on the provided materials; in Hybrid mode, it draws on general knowledge as well; and in Ungrounded mode, it does not rely primarily on its own knowledge base.

For example, agents handling product-related inquiries should have well-organized feature descriptions and FAQs on hand, and clearly define which questions they will not answer. Knowledge source models cannot replace accuracy checks: outdated parameters, ambiguities, and internal information in uploaded materials can all affect the responses provided to users.

What Kinds of Jobs Are Suitable?

• Training and Process Guidelines:Break down the instructor's script into multiple scenes, with a digital avatar providing explanations and screenshots, diagrams, or screen recordings used to illustrate details. This approach is suitable for courses that require regular content updates.
• Product Demos and Marketing Presentations:Maintain a consistent image across the video series by featuring the same characters. Specific parameters, prices, and commitments should be sourced from verified business materials; avoid letting the generated script fill in the details on its own.
• Site Map and FAQs:Use Visual Agent to handle visitor inquiries, answer questions based on publicly available information, and provide a human support channel for questions that fall outside the scope. Consider both knowledge management and the traffic generated by these interactions.
• Interactive Learning:Combine introductory explanations with Q&A sessions to encourage learners to continue asking questions after watching the video. The delivery methods for course content, interactive features, and standard video downloads should be designed separately.

How to Create a Digital Human Narration

Taking “Introduction to the Employee Onboarding Process” as an example, you can start by preparing the finalized process outline, department contact information, and a few screenshots of the business interfaces, and then followStudio Production ProcessOperation.

1. Create projects and roles.Select "Create video," use characters from the character library, or upload licensed content based on the selected type. When using photos, ensure they are taken from the front, well-lit, and show the face clearly; the recommended face size for official images is at least 200×200 pixels.
2. Enter a script or a recording.Enter your script in the "Script" section, select a voice, and preview it; you can also use a pre-recorded audio file. The audio upload limit is 10 MB and a maximum length of 5 minutes; supported formats include MP3, WAV, M4A, and others. This is the limit per upload and does not mean that all finished videos must be 5 minutes long.
3. Break down the scenarios by content.Explain one process step per slide, and include the corresponding interface or explanatory diagram. Duplicate the layout to maintain consistency, and use the media layer to arrange the positions of characters and diagrams.
4. Confirm that sound is being played.First, check the names of people, department abbreviations, and pauses, then click "Generate Video." After generation, review the lip-sync, audio-video synchronization, and text information, and download the final video from the project library.
5. Handling publication methods.If you need subtitle files, export them as SRT files using the appropriate method, and verify on the target platform that the subtitles load correctly. The scope of the licensing for characters and audio should cover the actual intended use of the publication.

If your goal is to create a Q&A service, you should go to the “Agents” section to create an agent: set the language and responsibilities, upload publicly available knowledge, select a response mode, and then test "questions within the knowledge base, questions outside the knowledge base, and questions prone to misunderstanding" in the preview. After confirming the scope of responses, publish the link or embed it on your website. Interactions generated after sharing will consume the creator’s account quota, so usage from public access points should also be factored into your budget.

StudioThe credit deduction is based on the video's duration, rounded up to the nearest 15-second increment; unused minutes do not carry over. Trial and Lite versions include a watermark;License AgreementThe Trial, Lite, and API Build plans are limited to personal use. When creating commercial content, you must select a plan that explicitly includes a commercial license and ensure you have the appropriate rights to the input images, audio, and scripts.

How Do D-ID and HeyGen Compare?

When creating pre-recorded instructional videos, D-ID andHeyGen AI StudioBoth support avatars, scenes, scripts, and user-provided assets. When selecting D-ID, the key considerations are the asset requirements for different types of digital humans and whether they will be used for interaction later on; HeyGen, on the other hand, allows you to set appearance and disappearance markers for elements within the script text, making it suitable for editing methods that involve comparing script timing with on-screen synchronization.

When real-time Q&A is required, the deployment processes should be compared separately. D-ID provides knowledge and behavior configuration for Visual Agent; HeyGen’s real-time product isLiveAvatar...It has its own plan and quota, so the real-time avatar cannot be used directly with the standard video avatar by default. Already purchasedVideo ProductionThe plan does not imply that real-time digital human services are included.

Therefore, first determine whether you need to deliver a video file or a Q&A portal capable of continuously serving visitors, and then compare the recording requirements, content control, embedding methods, and costs. Based on a single screenshot of a presentation, it is impossible to judge how it will perform within your own script, language, and deployment environment.
