To make an explainer video with AI, define one audience and one question, write a script that moves from problem to solution to how it works to a single next step, generate a clear conversational voiceover, pair every sentence with a visual that shows rather than decorates — screen recordings, diagrams, illustrations or stock footage — add captions, and export in the format of the place it will live: 16:9 for websites and YouTube, 9:16 for social feeds.
Explainer videos are short videos that make one thing easy to understand: what a product does, how a process works, why an idea matters. They used to require a script writer, a voice actor, an illustrator and an animator. In 2026, AI can produce a credible first version from a script in minutes. This guide covers the main types of explainer video, the ideal length for each, a script structure that works, how to choose visuals, voice and captions, the full step-by-step workflow, and how to distribute and measure the result.

What Is an Explainer Video?
An explainer video is a short video, usually between 30 seconds and a few minutes, that explains a product, service, process or concept in simple terms. Most combine a voiceover with visuals — illustrations, screen recordings, diagrams or footage — and many end with a clear next step such as signing up, trying a feature or watching the next lesson.
The defining feature is focus. A good explainer answers one question for one audience. “What is our product?” for first-time website visitors is one explainer; “How do I set up an integration?” for new customers is a different one. Trying to answer both in a single video is the most common reason explainers fail.
Types of Explainer Videos
Product and SaaS explainers: the homepage or landing page video that shows what a product does and why it matters, usually 60 to 120 seconds.
How-it-works videos: a step-by-step look at a process, a feature or a service, from ordering to delivery or from sign-up to first result.
Onboarding and help-center tutorials: short task-focused videos (“How to export a report”) that reduce support tickets.
Educational explainers: lessons that make a concept clear, from compound interest to photosynthesis.
Social explainers: 30 to 90 second vertical videos for TikTok, Reels and Shorts that explain a topic in your niche and build authority.
Internal training: policies, tools and processes explained for employees, which are far easier to update than a live training session.
Why Explainer Videos Work
People actively look for explanations on video. According to Pew Research Center, 51% of YouTube users say the platform is very important for helping them figure out how to do things they haven't done before.
Words plus pictures beat words alone. Research by educational psychologist Richard Mayer on multimedia learning found that people learn better from words and pictures together than from words alone, and that learning improves when extraneous material is cut, when key points are signaled, when information is broken into segments, and when narration is conversational rather than formal. Those principles map almost directly onto explainer video best practice.
Video scales explanation. A great salesperson or teacher can explain something to a few people at a time; a great explainer video can do it for every visitor, every day, in every time zone.
How Long Should an Explainer Video Be?
Length should match the viewer's intent and the place the video lives. At a natural narration pace of about 150 words per minute, these ranges work well:
Social explainers: 30 to 90 seconds, or roughly 75 to 225 words. One concept, a fast hook, one takeaway.
Homepage and landing page explainers: 60 to 90 seconds, or about 150 to 225 words. Enough to cover the problem, the solution and how it works, short enough that most visitors finish.
Product feature explainers: 60 to 120 seconds, about 150 to 300 words, focused on one feature or use case.
How-to tutorials: 2 to 5 minutes, depending on the number of steps. Viewers with a task in mind will watch longer if every second helps them finish it.
Educational lessons: 5 to 10 minutes for a full concept, ideally split into chapters or a series of shorter videos.
When in doubt, cut. Most first drafts of explainer scripts are 30 to 50 percent longer than they need to be. Our video length calculator converts a script's word count into an estimated runtime.
The Explainer Script Structure
Most effective explainers follow the same five-part arc. Adjust the time spent on each part to the video's length.
The problem: open with the viewer's situation in their own words. “Spending your Sunday scheduling a week of posts?” Recognition makes people keep watching.
The solution: introduce the product, method or idea in one sentence. Say what it is and who it's for.
How it works: three steps or three key points, each with a visual. Three is memorable; seven is a manual.
Proof or payoff: show the result — a before-and-after, a number, a finished output, a quick example.
The next step: one call to action. Sign up, try the feature, watch part two. Never three.
Write the way you'd explain it to a smart friend: short sentences, plain words, concrete examples, and jargon only when you define it immediately. A free video script generator can draft a first version to edit, and our guide on how to write a YouTube script goes deeper on pacing.
Choosing the Visual Style
Every visual should earn its place by showing something the narration describes. Decorative visuals that don't match the words split attention, which is exactly what multimedia learning research warns against.
Screen recordings: the clearest option for software. Show the actual interface, zoom in on the click that matters, and cut everything else.
Illustrations: clean flat vector, isometric or line-drawing styles explain abstract concepts and systems well and look consistent across a whole video library. Stick figures are a popular, friendly variation — see how to make stickman videos with AI.
Diagrams and text callouts: arrows, labels and simple charts signal the key point, but keep on-screen text short so it doesn't compete with the narration.
Stock footage: real-world footage works for service businesses and lifestyle topics, where showing people and places builds trust.
Talking head plus visuals: a founder, teacher or expert on camera with diagrams and b-roll layered in adds credibility, especially for courses and personal brands.
Voiceover and Captions
Voice: choose a clear, friendly, conversational voice at a natural pace of about 150 words per minute. Explainers should sound like a helpful colleague, not a commercial. Preview a few voices reading your opening line with our free text-to-speech tool before you commit.
Pronunciation: product names, acronyms and technical terms are where text-to-speech voices stumble. Listen to every instance and spell tricky terms phonetically in the script if needed.
Captions: always include them. Captions make videos accessible to deaf and hard-of-hearing viewers and useful to anyone watching in a noisy place or on mute, as the W3C's accessibility guidance explains. On social platforms, animated word-by-word captions also hold attention. An auto caption generator handles the timing, and an SRT subtitle generator creates files for YouTube and website players.
Music: optional and quiet. For tutorials, many viewers prefer no music at all.
How to Make an Explainer Video with AI: Step by Step
Step 1 — Define the audience, the question and the action. Write them as one sentence: “For new users who just signed up, explain how to publish their first post, so they publish one today.”
Step 2 — Write the script using the five-part structure, and cut it until every sentence is necessary.
Step 3 — Storyboard. Next to each sentence, note the visual: a screen recording, an illustration, a diagram or footage.
Step 4 — Generate the voiceover and check every name and term for pronunciation.
Step 5 — Create or collect the visuals. Record the screen flows, generate illustrations in one consistent style, and pull any stock footage.
Step 6 — Assemble and time. Each visual should appear exactly when the narration mentions it. Add zooms on key details and light motion on illustrations.
Step 7 — Add captions, your logo and brand colors, and a clear end card with the call to action.
Step 8 — Export the versions you need: 16:9 for your website, YouTube and help center; 9:16 cut-downs for TikTok, Reels and Shorts. Our aspect ratio guide covers each format.
The Fast Way: Explainer Videos with Vidpal
Vidpal Studio generates explainer videos from a topic, a full script or a URL. Pointing it at a product page, documentation article or blog post is a quick way to turn existing written material into a narrated video. Choose Long Video (16:9, 1 to 10 minutes) for websites and YouTube, or Short Video (9:16, 30 to 90 seconds) for social.
For visuals, choose AI Generated Images in a clean style such as Flat Vector, Isometric, Line Drawing or Stickman, or choose Stock Footage for real-world clips matched to each section. Review and edit the script before visuals are generated, rewrite any section with AI, and Studio adds a voiceover from the voice library and animated captions. Your brand kit applies your logo, colors, font and caption style automatically, so every explainer in a library looks related.
If your explainer starts with real footage — a screen recording or someone talking to camera — upload it to AI Editing instead. It adds captions, removes silences and filler words, inserts b-roll, adds zooms and reframes landscape footage to 9:16, which makes it easy to turn one recorded demo into both a website video and a social version. And if you have long webinars or recorded lessons, AI Clips pulls short explainer moments out of them; see how to turn a webinar into short clips.
Short videos use 1 credit and long videos 5 credits, and Studio exports require a paid plan. Plans and credits are on the pricing page, and the use cases page shows how teams use explainers across marketing, education and support.
Where to Publish and How to Measure
Website: place the product explainer near the top of the homepage or landing page, with the call to action right next to the video.
YouTube: publish full explainers and tutorials with keyword-rich titles and descriptions so they surface in search. Our free YouTube description and tags tool helps with metadata.
Social: cut 30 to 90 second vertical versions for TikTok, Reels and Shorts, each focused on one point.
Help center and onboarding emails: embed task tutorials next to the written instructions they illustrate.
Measure what the video is for. For marketing explainers, track completion rate and clicks on the call to action. For tutorials, track whether support tickets on that topic go down. For social explainers, track average watch time and saves. If viewers drop off early, the opening is too slow; if they drop off in the middle, a step is confusing or too long.
Common Explainer Video Mistakes
Explaining everything: one video, one question. Make a series instead.
Starting with the company instead of the problem: viewers care about their situation first.
Decorative visuals: pretty footage that doesn't show what the narration describes splits attention.
Too much on-screen text: long text blocks compete with the voice. Use short labels and captions.
Jargon: if your audience wouldn't use the word, don't use it — or define it immediately.
Robotic or rushed narration: slow down and choose a natural, conversational voice.
No clear next step: end with exactly one call to action.
Never updating: products change. Keep scripts in a document so you can regenerate the video when the interface or offer changes.

Takeaway three: use the problem, solution, how it works, proof and next step structure.
Takeaway four: every visual should show what the narration says, and captions should always be on.
Takeaway five: Vidpal Studio turns a script, topic or URL into an illustrated, voiced and captioned explainer, while AI Editing polishes screen recordings and talking-head explainers.
Frequently Asked Questions
How long should an explainer video be? Most marketing explainers work best at 60 to 90 seconds, social explainers at 30 to 90 seconds, and tutorials at 2 to 5 minutes. At about 150 words per minute, a 90-second explainer needs roughly 225 words of script.
Can AI make an explainer video from a script? Yes. AI video tools can generate the voiceover, create illustrations or match stock footage to each section, add captions and export the finished video. In Vidpal Studio you can paste a full script, describe a topic, or start from a URL such as a product page or article.
What is the best structure for an explainer video script? Problem, solution, how it works, proof, and next step. Open with the viewer's situation, introduce the solution in one sentence, explain it in three points with matching visuals, show a result, and end with a single call to action.
Do explainer videos need to be animated? No. Screen recordings, illustrated stills with motion, diagrams, stock footage and talking-head videos all work. Choose the style that shows the idea most clearly; for software, a well-edited screen recording usually beats animation.
How much does an explainer video cost to make? Agency-produced animated explainers can cost thousands of dollars per minute, while AI tools make it possible to produce a credible version for the cost of a subscription. Our guide to AI video tool pricing compares what different tools charge.
