Explainer videos have a scaling problem. A single 90-second product explainer used to require a scriptwriter, a designer, a voiceover artist, and an editor. Budget: $3,000 to $15,000. Timeline: two to four weeks.

Most teams could afford one or two per quarter, which meant choosing between explaining your product to new users or training your internal team, but rarely both.

AI has collapsed that timeline and budget without collapsing the quality. The tools available in 2026 let you go from a written brief to a finished explainer video in hours, not weeks. But the process still requires structure.

The teams producing great AI explainers aren't just typing prompts and pressing generate. They're following a production workflow that happens to use AI at every step.

This guide covers that workflow: how to plan, script, visualize, and produce explainer videos using AI tools, with specific attention to where AI adds the most value and where human judgment still matters.

What Is An AI Explainer Video?

An AI explainer video is a short video (typically 60-120 seconds) that explains a product, concept, or process, produced using AI tools for scriptwriting, visual generation, voiceover, and editing. AI handles the production bottlenecks while you maintain creative control over the message.

Traditional production follows a linear handoff model: brief to scriptwriter to designer to animator to editor. Each handoff introduces delays. AI-assisted production compresses these steps. A single person can move from script to storyboard to finished video within one platform, with execution time dropping from days to minutes.

How To Make An Explainer Video With AI: Step By Step

Step 1: Define Your Goal And Audience

Every effective explainer video solves one problem for one audience. If you try to explain everything your product does, you explain nothing well. Before touching any AI tool, write down:

• The one thing the viewer should understand after watching

• The one action you want them to take

• What they already know (so you don't waste time on setup)

• What they don't know (the gap your explainer fills)

Step 2: Write Or Generate Your Script

The script is the single most important element of any explainer video. No amount of visual quality compensates for a weak script. AI can draft it, but you need to shape it.

Use this structure for explainer scripts:

1. Problem (0-15 seconds): Open with a pain point the viewer experiences.

2. Solution (15-25 seconds): Introduce your product or concept in one clear sentence.

3. How It Works (25-65 seconds): Walk through 3-4 steps or capabilities. Each point gets 10-15 seconds.

4. Benefit (65-80 seconds): Summarize what changes for the viewer.

5. CTA (80-90 seconds): One clear next step.

For word count: roughly 150 words per 60 seconds of voiceover. A 90-second explainer needs approximately 200-225 words.

Use an AI script generator for the first draft, then edit aggressively. Read the script aloud before you move to visuals.

Step 3: Create A Visual Storyboard

Once the script is solid, break it into scenes. Each major point becomes a separate visual scene with its own shot description, mood, and key elements.

LTX Studio's AI storyboard generator automates this step. Paste your script into the platform and the AI divides it into scenes, generates visual references for each shot, and creates a sequence you can rearrange and refine.

Step 4: Generate Your Visuals With AI

With a storyboard in place, generate the visual content for each scene. Key considerations:

• Style consistency: Choose a visual style before generating and apply it uniformly across all scenes.

• Character consistency: Platforms like LTX Studio let you save characters as reusable Elements that maintain visual consistency throughout the video.

• Scene duration: Generate clips that match your script timing.

• Motion and pacing: Explainer videos benefit from moderate, purposeful motion. Avoid hyperactive camera movement.

Step 5: Add Voiceover And Audio

AI voice generators produce natural-sounding narration in multiple languages. LTX Studio's audio tools let you add voiceover directly within the platform and sync it with your generated visuals. If your brand has a recognizable voice, recording separately adds authenticity.

Both options benefit from subtle background music. Keep music lower in the mix than the voice.

Step 6: Edit, Review, And Export

The final editing pass aligns timing between visual scenes and voiceover segments, adds on-screen text for key terms and CTAs, and verifies brand consistency. If you're using LTX Studio's Brand Kit, that consistency is built into the generation process. Match export format to your channel: 1080p for YouTube, 1080x1920 vertical for Reels and TikTok.

AI Explainer Video Use Cases

Product explainers: SaaS companies are the heaviest users. Products complex enough to need an explanation are usually evolving fast enough that static docs fall behind. AI-generated explainers can be updated in hours when features change.

Onboarding and training: Internal training is one of the highest-ROI applications. The audience is captive, production frequency is high, and the quality bar is clear and professional rather than award-winning.

Social media explainers: Compressed structure: 3-second hook, 20-second explanation, CTA. AI generation meets the visual quality bar of social feeds while enabling the volume needed for consistent posting.

Explainer Video Best Practices

Keep it under 90 seconds. Engagement drops sharply after that mark. Split complex topics into a series of shorter videos.

Hook viewers in the first 5 seconds. Open with a specific problem or a surprising fact that creates a knowledge gap.

One CTA. A single, specific next step the viewer can take immediately.

Maintain brand consistency. Use a consistent style reference for every scene, and if your platform supports it, use a Brand Kit to lock in colors, styles, and character appearances across the project.

How Much Do AI Explainer Videos Cost?

Traditional production: A 90-second animated explainer from an agency typically runs $5,000 to $15,000 with a 3-6 week timeline.

AI-assisted production: The same video can be produced for platform subscriptions ($20-$100/month) plus several hours of human time. Total cost per video: $200 to $500. Revisions are trivial since you can regenerate scenes in minutes. The real savings are in what becomes possible: a team that could afford two explainer videos per quarter can now produce two per week.

Conclusion

The AI explainer video workflow in 2026 isn't about pressing a button and receiving a finished video. It's about compressing the production timeline so that the creative decisions get more of your time, and the execution gets less.
