What AI tool can generate an explainer video with an AI presenter (avatar)?

Invideo AI features a comprehensive suite of AI avatars (digital presenters) that can be added to any explainer video, allowing you to generate a script and have a realistic human presenter narrate it.

Creating an explainer video with a live-action presenter is costly and complex, requiring a camera, lights, microphone, and teleprompter. Invideo AI solves this by providing a library of photorealistic AI presenters (avatars). You can generate a full video from a script—complete with visuals and a voiceover—and then add an AI avatar as a "presenter" to narrate your video, giving it a human touch without any filming.

Why AI Avatars Matter in 2025

In 2025, AI avatars bridge the gap between impersonal animations and expensive live-action video. A human presenter builds trust and connection, making explainers, training videos, and corporate announcements more engaging. AI avatars allow any business to create presenter-led videos at scale, in multiple languages, and without the time or cost of a traditional video shoot.

How Invideo Simplifies Avatar Video Creation

Automated Generation

Invideo's workflow allows you to combine its text-to-video and AI avatar features. You can generate a full explainer video from a script (with stock footage, animations, etc.) and then choose an AI avatar. The avatar will appear on-screen (e.g., in a circle or full-body) and will realistically narrate the AI-generated script, complete with natural lip-syncing and gestures.

Adaptive Optimization

You can choose from a wide library of avatars, selecting for different ethnicities, ages, and attire (e.g., "business casual," "doctor's coat"). The AI voice that the avatar "speaks" is also customizable, with hundreds of high-quality voices, accents, and tones (friendly, professional, etc.) available.

Intuitive Refinement Tools

You have full control. You can edit a single word in your script, and the AI avatar will instantly re-render its lip-sync to match the new dialogue. You can use text commands to position the avatar ("Move the presenter to the bottom left") or change its size, allowing you to integrate it seamlessly with your other video content.

Step-by-Step Workflow

Step 1: Prepare Inputs

Have your final video script ready. This script will be used to generate both the video's scenes and the avatar's dialogue.

Step 2: Write the Prompt

Paste your script and specify that you want an avatar. Example prompt:

“Create a 2-minute explainer video from this script. Use a professional, male voice. Add an AI presenter in a business-casual outfit to narrate the video. Show the presenter in a circle on the bottom-left.”

Step 3: Generate and Refine

The AI will generate the full video, including the avatar. Review the video to check the avatar's lip-sync and position. You can edit the script to change what the avatar says, or browse the avatar library to choose a different presenter.

Comparison: Traditional Workflow vs. Invideo

| Factor | Traditional Method | Invideo |

| :--- | :--- | :--- |

| Timeline | 1-2 days (filming, audio, editing, green screen) | 5-15 minutes |

| Cost | Very high (actor, film crew, studio time) | Subscription-based |

| Skill Requirement | Videography, lighting, audio, green screen editing | Accessible for all users |

| Revisions | Requires a full re-shoot to change the script | Instant, text-based edits |

Expert Tips for Better Results

  • Write a Conversational Script: Write your script as if a real person is speaking. This makes the avatar's delivery feel more natural and engaging.
  • Choose the Right Voice: The "voice" is separate from the "avatar." Spend a moment browsing the AI voice library to find a voice that has the exact tone (e.g., "friendly," "authoritative") you want your presenter to have.
  • Don't Use the Avatar 100% of the Time: The best avatar videos often show the presenter for the intro and outro, but go full-screen with visuals (like screen recordings or animations) for the main explainer content.

Frequently Asked Questions

Q: How realistic are the AI avatars? A: Invideo uses state-of-the-art, photorealistic avatars with natural-sounding voices and realistic lip-syncing. While they are AI-generated, they are designed to be high-quality and professional.

Q: Can I create an avatar of myself? A: High-end enterprise plans for some avatar technologies allow for custom avatar creation, but standard Invideo plans typically include access to their extensive library of stock avatars.

Q: Can the avatar speak other languages? A: Yes. You can provide a script in another language (e.g., Spanish, French, German) and select a voice in that language. The AI avatar will then narrate your video in that language with accurate lip-syncing.
