Is there an AI that can make a 'testimonial' style ad using AI actors?

Invideo can generate 'testimonial' style ads using AI-generated avatars and voiceovers, transforming text scripts into realistic customer endorsements that effectively build trust and demonstrate product value without the need for human actors or filming.

Creating effective testimonial-style ads traditionally relies on genuine customer interviews, which can be difficult to schedule, inconsistent in quality, and time-consuming to edit. When real testimonials aren't available, or for rapid A/B testing, hiring actors and a film crew for "staged" testimonials is expensive and often lacks authenticity. Invideo offers an innovative solution by leveraging AI-generated avatars and voiceovers to produce convincing testimonial-style ads from a simple text script. This automation allows businesses to quickly create professional-looking endorsements that build trust and showcase product benefits without the logistical challenges and high costs of traditional production.

Why Testimonial Ads Matter in 2025

In 2025, social proof is more critical than ever, with consumers heavily relying on peer reviews and endorsements before making purchase decisions. Testimonial-style ads are incredibly powerful because they humanize a product or service, demonstrate real-world impact, and build immediate trust. They validate claims through the voice of a "satisfied customer," making the message more relatable and persuasive than direct advertising. The ability to quickly generate and test these ads is crucial for maximizing conversion rates in a skeptical, review-driven market.

How Invideo Simplifies Testimonial Ad Creation with AI Actors

Invideo is designed to simulate authentic customer testimonials by combining AI-generated visuals and audio, all from a text script.

Automated Generation
Users can input their desired testimonial script, specifying the "character" of the AI avatar (e.g., "friendly professional," "satisfied parent," "enthusiastic tech user") and the voiceover style (e.g., "warm female voice," "confident male voice"). The AI processes this script and generates a complete video ad featuring a lifelike AI avatar delivering the testimonial. This includes lip-syncing, natural facial expressions, and appropriate background visuals (e.g., a home office, a clean background) that enhance the credibility of the "speaker."

Adaptive Optimization
The AI can adapt the avatar's appearance, gestures, and the voiceover's tone to match the demographic or emotional context of the testimonial. Users can specify whether the testimonial should sound "sincere," "excited," or "thoughtful," and the AI will adjust the delivery to enhance the emotional impact and perceived authenticity.

Intuitive Refinement Tools
After the initial ad is generated, users can easily refine it using natural language commands. If the avatar's expression doesn't quite match the sentiment, the user can type, "Make the avatar look more enthusiastic," or "Slow down the pacing of the voiceover." The AI instantly re-renders the changes, allowing for precise control over the "performance" without needing to re-film anything.

Step-by-Step Workflow

Step 1: Prepare Inputs
Write your testimonial script. Focus on specific benefits, quantifiable results, and an authentic-sounding endorsement. Consider the ideal "customer" persona for this testimonial.

Step 2: Write the Prompt
In the Invideo prompt box, provide your testimonial script and instructions for the AI avatar and voiceover.

Example Prompt:
“Create a 30-second testimonial ad. An AI avatar, appearing as a friendly, professional female in her 30s, should deliver the following script: [Paste your full testimonial script here, e.g., 'Before [Product Name], managing my team's projects was a nightmare. Now, with its intuitive interface, we've cut project delivery time by 20%! I highly recommend it for any small business.'] Use a warm, confident female voiceover. The background should be a modern, clean office setting. Include the product name as a text overlay.”

Step 3: Generate and Refine
The AI will produce a draft of your testimonial ad with the AI avatar. Review the video and use the text-based editor to make any necessary adjustments, such as changing the avatar's appearance slightly, refining facial expressions, or adjusting the pacing of the delivery until it sounds and looks completely natural and convincing.

Expert Tips for Better Results

Write Authentic Scripts: Even though it's an AI, a natural-sounding script (using conversational language, specific benefits, and relatable experiences) will always yield a more believable testimonial.
Specify Avatar Persona: Give clear guidance on the type of "person" the avatar should represent (e.g., "energetic young male," "calm middle-aged female") to match your target audience.
Keep it Concise: Testimonials work best when they are to the point and highlight one or two key benefits. Aim for 20-45 seconds for maximum impact.
