You don't need to hire an animator, learn Adobe Premiere, or spend weeks on production. An AI explainer video generator can turn a script, PDF, or even a single topic into a finished, narrated whiteboard animation in under an hour — and you can do it without touching a timeline or learning a single keyboard shortcut.
This guide walks you through the entire process, from choosing your input to publishing a polished video.
What input format works best for your explainer video?
The first decision is how you'll feed your idea into the tool. Most AI video generators accept multiple formats, and the one you choose shapes how much work you do upfront.
Topic or one-liner: If you have a rough idea but no script yet, you can feed the tool a single sentence — e.g., "How photosynthesis works" or "Why startups fail." The AI will generate a script and animate it. This is fastest but gives you the least control over messaging.
Full script: If you've already written or have a script ready, paste it directly. This is the most common path for corporate training, product demos, and marketing. You keep full control over the exact words, tone, and flow. The AI handles the visuals and narration.
PDF or document: Upload a whitepaper, blog post, or training manual. The AI extracts the key points and builds a video from them. Useful if you want to repurpose existing content without rewriting.
Reference image: Some generators let you upload a diagram, flowchart, or screenshot to guide the visual style. This ensures the video matches your brand or technical requirements.
Verdict: Start with a script if you have one. It gives you the most control and usually produces the best results because you've already thought through the message. If you're starting from scratch, a one-liner is fine for quick internal videos; for anything client-facing or high-stakes, spend 15 minutes writing a rough script first.
How do you actually create the video step-by-step?
Once you've chosen your input, the process is straightforward. Here's what happens:
Step 1: Sign up and choose your plan
Most AI video generators offer a free tier or trial credits. Ankon AI gives you 2 free credits on signup — enough to test the tool with a short video. If you're planning to make multiple videos, a paid plan makes sense. The Starter plan ($29/mo) includes 15 credits, which covers roughly 7–8 standard videos depending on length and features.
No credit card is required to start with the free credits.
Step 2: Prepare your input
If you're using a script, have it ready to paste. Keep it between 200–500 words for a typical 2–4 minute video. Shorter scripts work better — they're easier for the AI to visualize and keep the viewer's attention.
If you're uploading a document, make sure it's a clean PDF or text file. The AI will extract the main ideas, so don't worry about perfect formatting.
Step 3: Create a new video and select your input method
In the tool, click "Create" or "New Video." You'll see options: - Paste a topic - Paste a script - Upload a document - Upload a reference image
Choose the one that matches your input, then paste or upload.
Step 4: Choose your narration language and voice
Most AI video tools support 8+ languages with AI text-to-speech. Select your language. If you want a more personal touch, some tools (like Ankon AI on Pro plans and up) offer voice cloning — record a 10-second sample of your own voice once, and the AI will narrate in your voice across all languages.
For a quick internal video, the default AI voice is fine. For client-facing content, voice cloning or a professional voiceover adds credibility.
Step 5: Enable optional enhancements
Many generators offer features that improve the final video: - Enhance mode: Doubles the number of scenes for smoother transitions and richer visuals. This makes the video feel more polished but costs more credits. - Fact-check: An independent pass that flags any made-up facts in your script. Useful for educational or compliance videos. - Captions: Burned-in captions or SRT export for accessibility and social media. - Custom branding: Add your logo to the video.
For a first video, skip the extras. Once you see the output, you'll know whether they're worth the cost.
Step 6: Generate and wait
Hit "Generate" or "Create Video." The tool will: 1. Parse your input and build a script (if you gave it a topic) 2. Generate visuals — whiteboard scenes, diagrams, animations 3. Render the video with narration 4. Export as an MP4
This usually takes 2–10 minutes depending on the tool and video length. Some generators offer fast render at no extra cost.
Step 7: Download and review
Once the video is ready, download the MP4. Watch it all the way through. Check for: - Accuracy: Did the AI get the facts right? - Pacing: Is it too fast or too slow? - Visuals: Do the animations match the narration? - Audio: Is the voiceover clear and natural?
If something's off, most tools let you regenerate or edit specific scenes without starting over.
What should you do if the first version isn't perfect?
AI video generators aren't flawless. Common issues and fixes:
The script is inaccurate or misses key points. If you used a topic or document input, the AI may have misinterpreted your intent. Solution: Regenerate with a full script instead. You control every word.
The visuals don't match the narration. The AI might draw a chart when you meant a diagram, or animate the wrong concept. Solution: Most tools let you edit individual scenes — swap the visual, adjust the timing, or re-narrate that section.
The voiceover sounds robotic or unnatural. Default AI voices are improving but still lack warmth. Solution: Use voice cloning if available, or record a professional voiceover and upload the audio file.
The video is too long or too short. If you're over time, trim the script and regenerate. If it's too short, add more detail to your script.
The branding or colors don't match. Some tools let you customize the color palette and add logos. Check the settings before regenerating.
The pacing feels off. Adjust the narration speed or break long sentences into shorter ones. Shorter sentences = more visual breaks = better pacing.
How much does it cost to make an explainer video with AI?
Pricing varies by tool and video length. Most use a credit system where 1 credit = 1 minute of finished video (with a 2-credit minimum per video).
Free tier: Ankon AI gives 2 free credits on signup, enough for one short test video.
Subscription plans: Monthly plans range from $29–$249/mo depending on how many videos you plan to make. A $29/mo Starter plan includes 15 credits, which covers roughly 7–8 videos at standard quality. If you enable Enhance mode (smoother, more detailed animations), each video costs twice as many credits.
Pay-as-you-go: If you only need one or two videos, top-up credits are usually cheaper per-video than a subscription. Most tools charge $2 per credit, with a $10 minimum.
Verdict: For a one-off video, buy 5–10 credits. For regular content (weekly or monthly), a subscription saves money. Annual billing often includes a ~20% discount.
What's the fastest way to go from idea to finished video?
If you're in a hurry, here's the speed-run:
- Write a tight script (10 minutes). 200–300 words, one main idea, clear structure.
- Paste it into the tool (1 minute). Select your language and default voice.
- Skip enhancements (0 minutes). Enhance mode and fact-check add time and cost; save them for important videos.
- Generate (5–10 minutes). Most tools render in under 10 minutes.
- Download and spot-check (5 minutes). Watch it once. If it's good, you're done.
Total time: 20–30 minutes from blank page to finished video.
Compare that to hiring a freelancer (1–2 weeks), learning animation software (weeks), or outsourcing to a studio (weeks + thousands of dollars). AI video generation is orders of magnitude faster.
When should you use an AI explainer video instead of other formats?
AI video works best for: - Internal training: Onboarding, process documentation, compliance training. - Product demos: Show how a feature works without recording your screen. - Educational content: Explain concepts, theories, or workflows. - Marketing: Quick explainers for landing pages, social media, or email. - Repurposing content: Turn a blog post, whitepaper, or FAQ into a video.
AI video works less well for: - Live-action or testimonials: If you need real people on camera, you'll need to film. - Highly technical or niche topics: AI may struggle with specialized jargon or very specific visuals. - Brand-heavy content: If your brand requires a specific visual style or custom illustrations, you might need a designer.
How do you make sure your explainer video is actually good?
A fast video isn't useful if nobody watches it. Here's how to make it engaging:
Keep it short. 2–4 minutes is ideal. Anything over 5 minutes loses attention.
Start with the problem, not the solution. "Most teams waste 5 hours a week on manual data entry" is more compelling than "Our software automates data entry."
Use simple language. Avoid jargon. If you must use technical terms, define them in the video.
Pace the visuals. Don't let a single scene sit for more than 10–15 seconds. Enhance mode helps here by adding more scenes.
Add captions. 80% of videos are watched without sound. Burned-in captions ensure your message lands even if the viewer has audio off.
Include a clear call-to-action. End with what you want the viewer to do: "Sign up for a free trial," "Read the full guide," "Schedule a demo."
Test with a real audience. Share it with a colleague or friend who isn't familiar with the topic. If they understand it, you're good.
What's the best AI tool for making explainer videos?
Several tools can generate explainer videos, but they differ in ease of use, output quality, and cost.
Ankon AI is purpose-built for whiteboard and explainer videos. You can input a topic, script, PDF, or image, and it generates a narrated animation with AI voiceover in 8+ languages. The credit model is transparent: 1 credit per finished minute (2-credit minimum), and you can see exactly what each feature costs before you generate. Enhance mode doubles the visual detail, and voice cloning lets you narrate in your own voice. The free 2 credits let you test without a card.
Other tools exist, but they often have steeper learning curves, less transparent pricing, or require more manual work (like selecting scenes or adjusting timing by hand).
For a first explainer video, Ankon AI is the fastest path from script to finished video.
Key takeaways
Making an explainer video with AI is now within reach of anyone with a script and 20 minutes. You don't need design skills, video editing experience, or a big budget. The process is:
- Write or gather your input (script, topic, or document).
- Choose your tool and sign up (free credits available).
- Paste or upload your input, select your language and voice.
- Generate the video (5–10 minutes).
- Download, review, and share.
If the first version isn't perfect, regenerate or edit specific scenes. Most tools let you iterate without starting from scratch.
The cost is low — free to test, $29–$249/mo for regular use — and the time savings are massive. What used to take weeks and thousands of dollars now takes hours and tens of dollars.
