Explainer videos are one of the highest-converting pieces of content a business can produce. A 90-second explainer video on a product page increases conversion rates by 80 percent on average. And in 2026, creating one no longer requires an animation studio, a voiceover artist, or a five-figure production budget.
AI explainer video tools have made the process accessible to solo creators, small businesses, and startups who need professional-quality animated explainer video content at a fraction of traditional costs. Here’s how to create one from scratch.
What Is an AI Explainer Video?
An AI explainer video is a short, structured video (typically 60 to 180 seconds) that explains a product, service, concept, or process using AI-generated visuals, AI voiceover, motion graphics, or animated AI avatars, produced without traditional animation studios, voiceover recording sessions, or expensive production crews.
The category covers several distinct formats. Whiteboard-style animated explainers with AI-generated illustrations. Slide-based explainers with AI voiceover and stock footage. Avatar presenter explainers using HeyGen or Synthesia avatars delivering a structured pitch. Text-to-video explainers generated automatically from a script by tools like InVideo AI or Pictory.
The best format depends on your content type, your brand aesthetic, and your target audience. Software products often use screen recording-based explainers with AI voiceover. B2B services often use avatar presenters. Consumer products often use animated explainers or product showcase video formats.
The common thread across all formats is the goal: explain clearly, build trust quickly, and move the viewer toward a specific next action.
Why Explainer Videos Work and When to Use Them
AI explainer videos in 2026 work because they combine information density with low cognitive load, explaining complex value propositions in 60 to 90 seconds in a format that is faster to consume than reading, more engaging than static text, and more scalable than one-to-one sales calls.
- Comprehension. Viewers retain 95 percent of information from video versus 10 percent from text, according to research on multimedia learning. Explainer videos communicate faster and stick better.
- Trust. A well-produced explainer video signals that a business is serious, professional, and trustworthy. The production quality of your explainer video communicates your brand quality before a viewer reads a single word.
- Conversion. Product pages with explainer videos consistently outperform pages without them. The video answers the key objection question “does this actually work” faster than text can.
- Shareability. Short, clear explainer videos are shared more than any other business content type. They explain your value proposition in a format that’s natural to share.
- SEO. Pages with video rank higher on average and have lower bounce rates. Explainer videos on landing pages improve both metrics.
When to use AI explainer videos:
- Product or service homepage introduction
- Onboarding video for new customers or users
- Sales deck supplement for complex products
- Social media product introduction content
- Email marketing with embedded explainer links
- Trade show or event background content

How to Create an AI Explainer Video Step by Step
This walkthrough creates a product explainer video using Synthesia, the most professional presenter-style option.
Step 1: Define your explainer video purpose precisely.
Before writing a word, answer these questions: Who is this video for? What is the one problem it addresses? What action do you want the viewer to take after watching? Explainer videos that try to cover everything convert poorly. The most effective explainers address one problem, show one solution, and ask for one action.
Step 2: Write your script using the Problem-Solution-Proof-Action structure.
Structure every explainer script the same way:
- Problem (10 to 15 seconds): State the specific pain point your audience experiences
- Solution (20 to 30 seconds): Introduce your product or service as the solution
- How It Works (30 to 45 seconds): Briefly explain the key features or process
- Proof (10 to 15 seconds): One compelling result, statistic, or testimonial reference
- Call to Action (10 to 15 seconds): One specific next step
Keep the total script to 150 to 200 words for a 60 to 90 second video. Read it aloud and time yourself before finalizing.
Step 3: Choose your Synthesia avatar and template.
Open Synthesia, start a new project, and choose a template designed for product explainers. Browse avatars and select one that matches your brand personality and your audience’s expectations. Professional B2B content needs a different avatar energy than a consumer app.
Step 4: Build your scenes.
Break your script into 5 to 8 scenes corresponding to the structure above. In each scene:
- Paste the corresponding script segment
- Add a relevant background or visual
- Add any text overlays highlighting key benefits or statistics
- Add your logo to maintain brand consistency
Step 5: Generate and review.
Generate the complete video. Review it end-to-end from a viewer’s perspective, not an editor’s perspective. Ask: does this clearly explain the value? Does the pacing feel natural? Is the call to action compelling and clear?
Step 6: Export and deploy.
Export as 1080p MP4. Embed on your product page, share on LinkedIn, upload to YouTube, and use in email marketing. Create a 30-second cut for paid social advertising and Instagram Reels.
Pro Tip: Test two different calls to action in your explainer video. One direct (“Start your free trial at link”) and one softer (“Learn more at link”). Track which drives more conversions on your landing page. This small difference can have a significant impact on conversion rate.

Writing a Script That Actually Converts
The script is where most explainer videos succeed or fail. AI tools can execute a bad script perfectly and produce a perfectly bad explainer video. These principles consistently produce better-converting explainer scripts.
Lead with the problem, not your product. Viewers don’t care about your product. They care about their problem. Spend the first 15 seconds on the specific pain they feel. Make them feel understood before you offer a solution.
Use numbers. “Save 5 hours per week” is more persuasive than “save time.” “3 simple steps” is clearer than “simple process.” Specific numbers build credibility and are more memorable than vague claims.
One feature, one benefit, one sentence. Explainer scripts often fail by listing features. Viewers don’t buy features. They buy the outcomes those features produce. For every feature you mention, connect it immediately to a specific outcome the viewer cares about.
End with urgency or specificity. “Visit our website” is a weak CTA. “Start your free 14-day trial at msyeditor.com” is specific, has urgency (14 days), and gives the viewer a clear next action and destination.
Common Mistakes to Avoid
- Making the explainer too long. The most common explainer video mistake. 60 to 90 seconds is the conversion sweet spot. Longer videos communicate more but convert less. Edit ruthlessly. Every sentence that doesn’t move the viewer toward the CTA should be cut.
- Starting with your company name. “Hi, we’re [Company Name]” is the least compelling way to start an explainer. Start with the problem or a question that hits the viewer’s pain point. Lead with them, not with you.
- Using jargon your audience doesn’t use. Technical language that impresses insiders confuses outsiders. Write your script at the language level of someone who has the problem you solve but doesn’t yet know your industry’s vocabulary.
- Skipping the proof element. A problem-solution structure without any evidence that the solution works is just a claim. Include at least one statistic, customer result, or credible reference that validates the solution. Even one piece of proof dramatically increases credibility.
- Not including a clickable CTA. An explainer video without a clear, specific, actionable call to action is just an explanation. Every explainer video should end with a specific next step that the viewer can take immediately. Make it easy: one action, one destination.
FAQs
Q: How long should an AI explainer video be?
A: 60 to 90 seconds is the optimal length for most conversion-focused explainer videos. Social media platforms perform best with 60 to 90 second explainers. Website landing pages can support up to 2 to 3 minutes for more complex products. Longer than 3 minutes typically sees significant drop-off in completion rates.
Q: What is the best AI tool to create an animated explainer video?
A: Vyond and Animaker produce the classic 2D animated character style. Synthesia and HeyGen produce presenter avatar-style explainers. InVideo AI and Pictory generate text-to-video explainers fastest. The best tool depends on which style best fits your brand and audience.
Q: How much does it cost to create an AI explainer video?

Q: Do I need to write the script myself or can AI write it?
A: AI writing tools (Claude, ChatGPT, InVideo’s built-in AI) can generate strong first-draft explainer scripts from your product description and target audience. Always edit AI scripts to add your specific product details, real statistics, brand voice, and a call to action tailored to your actual conversion goal.
Q: Can I use AI explainer videos for YouTube ads?
A: Yes. AI explainer videos work well as YouTube pre-roll ads, particularly the first 5 seconds (which must capture attention before the skip button appears) and the call to action at the end. Keep ad-format explainers under 30 seconds for best performance in skippable ad formats.
