Is there an AI tool that can create an explainer video with a realistic AI host?

Yes, Invideo AI can generate explainer videos featuring a realistic AI host (or 'digital presenter'), which can narrate your script with accurate lip-syncing and gestures, all without a camera.

Creating a "talking head" or "presenter-led" video is traditionally a barrier for many. It requires a camera, microphone, lighting, and a confident on-screen presenter. Invideo AI's "AI Avatar" feature solves this. You can type a script, and the AI will generate a full explainer video—with visuals and text—and also generate a photorealistic AI host to present the information, giving your video a professional, human touch.

Why AI Hosts Matter in 2025

In 2025, human connection is key to building trust. An AI host (or avatar) provides a "face" for your brand, making explainers, training modules, and announcements feel more personal and engaging than a simple voiceover or animated text. This technology allows any business to create presenter-led videos at scale, in any language, without the high costs and logistical hurdles of filming.

How Invideo Simplifies AI Host Video Creation

Automated Generation

Invideo's AI can generate a video from your script, complete with stock footage, text overlays, and background music. As part of this, you can choose to add an AI host from a large library of diverse, photorealistic avatars. The AI host will automatically "speak" your script with natural-sounding intonation and accurate lip-syncing.

Adaptive Optimization

You have full control over the host's appearance and voice. You can choose from dozens of avatars in various "attire" (e.g., business, casual, medical) and select from hundreds of high-quality AI voices in different accents and languages. You can also choose the host's framing (e.g., full-body, waist-up, or in a circle).

Intuitive Refinement Tools

Editing an AI host is as simple as editing text. If you change a word in your script, the AI host will instantly re-render its speech and lip-sync to match. You can use text commands to "Move the host to the right side" or "Make the host's circle smaller in this scene."

Step-by-Step Workflow

Step 1: Prepare Inputs

Have your final, polished script ready. This will be the dialogue for your AI host.

Step 2: Write the Prompt

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

“Create a 2-minute explainer video from this script. Add a realistic AI host to present the video. Use a female presenter in a business-casual outfit and a friendly, professional American voice. Show her on the left side of the screen.”

Step 3: Generate and Refine

The AI will generate the full video with the host. Review the host's performance. You can easily swap the avatar for a different one, try a different AI voice, or edit the script.

Comparison: Traditional Workflow vs. Invideo

| Factor | Traditional Method | Invideo |

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

| Timeline | 1-2 days (filming, audio setup, editing, re-takes) | 5-10 minutes |

| Cost | Very high (actor, camera/audio gear, studio) | Subscription-based |

| Skill Requirement | Videography, lighting, audio engineering | 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, not like a formal document. This makes the AI host's delivery sound much more natural.
  • Combine Host with Full-Screen Visuals: Don't show the host 100% of the time. The most effective videos introduce the topic with the host, cut to full-screen visuals (like stock footage or screen recordings) for the main points, and then return to the host for the conclusion.
  • Use Voice Cloning: For a truly on-brand video, you can use Invideo's Voice Cloning feature to have the AI host speak in a clone of your voice.
