- Use ChatGPT or Gemini to write a 15-30 second script, then generate video clips with Canva (up to 8 seconds), CapCut (script-to-video), or Seedance 2.5 (up to 30 seconds with sound).
- Add AI voiceover with CapCut or Canva’s text-to-speech, then captions for accessibility and sound-off viewing.
- Export in the right aspect ratio: 9:16 for Instagram Stories and TikTok, 1:1 for feed posts, 16:9 for YouTube.
- Never use fake testimonials, impersonate real people, or someone’s face or voice without consent. Many platforms require AI content to be labelled.
An AI commercial generator helps you create short video ads by writing a script with a chat assistant, generating or filming shots with AI video tools, adding voiceover and captions, then exporting the finished ad. You can make a 15-30 second commercial in an afternoon without video editing experience or a production budget.
What Is an AI Commercial Generator?
An AI commercial generator is a combination of tools that turn a product description or marketing idea into a finished video ad. It typically includes a text model (like ChatGPT or Gemini) to write the script, a video generation tool (like Canva, CapCut, or Seedance) to create the visuals, and editing features for voiceover, captions, and music.
Most small businesses use these tools in sequence rather than a single all-in-one platform. The advantage is flexibility: you can write a script in ChatGPT, generate clips in Canva, and add voiceover in CapCut, picking the best free or low-cost option at each step.
These tools answer searches for “ai commercial” (searched roughly 2,400 times per month) because they let you make ads without hiring a videographer or learning professional editing software.
Step 1: Write Your Script with a Chat Assistant
Start by opening ChatGPT, Gemini, or another chat assistant and describing your product or service. A good prompt includes what you sell, who it’s for, and the one benefit you want to highlight.
Example prompt: “Write a 20-second script for a Facebook ad selling handmade dog collars. Target: dog owners who want durable, stylish collars. Highlight: machine-washable and comes in 12 colors.”
The assistant will give you a short script with a hook (the first line that grabs attention), a benefit statement, and a call to action (“Shop now” or “Visit our site”). Read it out loud and edit anything that doesn’t sound like how you’d actually talk. Authenticity matters more than polish.
Keep the script to 15-30 seconds when read at normal speed. That’s roughly 40-80 words. Shorter ads cost less to run and hold attention better on social platforms.
Free plans on ChatGPT and Gemini are enough for script writing. You don’t need a paid subscription for this step.
Step 2: Generate or Film Your Video Clips
Now turn the script into video. You have three main approaches: generate clips from text prompts, convert the script directly to video, or film short clips yourself and enhance them with AI.
Canva: Create a Video Clip
Canva offers a “Create a Video Clip” feature on its free and paid plans. You type a description of the scene you want (“a golden retriever running through a park” or “hands fastening a colorful dog collar”) and Canva generates up to 8 seconds of video with sound.
The clips work best for B-roll (background footage) and abstract concepts. For faces, products, or specific branding, you’ll get better results filming your own footage or using stock video from Canva’s library and adding AI enhancements.
Canva’s free plan includes limited video generation credits per month. Check Canva’s pricing page for current limits on your account.
CapCut: AI Video Maker
CapCut’s AI video maker (available in the mobile and desktop app) converts a script into a video by matching your text to stock footage, adding transitions, and syncing it to music. You paste your script, pick a style (modern, playful, elegant), and the tool assembles a draft.
This approach is fastest for ads where stock footage fits your message: lifestyle shots, nature, cityscapes, or generic product use. It’s less effective if you need to show your specific product or storefront.
CapCut is free with watermark removal available on paid plans. Visit the app or CapCut’s site for current export options.
Seedance 2.5: Longer AI Video
Seedance 2.5, developed by ByteDance, generates video clips up to 30 seconds long with sound from a text description. According to the Convly models database, it costs from $0.097 per second when accessed through API providers.
Seedance works well for full-length ads where you want a single generated scene (a product showcase, an animated explainer, or a stylized brand moment) rather than stitching multiple clips together. The 30-second limit matches the typical length of a social media ad.
Seedance is currently available through third-party platforms that integrate ByteDance’s video models. Availability and pricing vary by provider, so check the platform’s own page before committing. Read more about Seedance 2.5 and how it compares to other tools.
Mixing Approaches
Many small businesses combine methods: film 5 seconds of product footage on a phone, generate 8 seconds of B-roll in Canva, and use CapCut to stitch them together with transitions. This hybrid approach gives you control over the hero shot (your product) while AI fills in the supporting visuals.

Step 3: Add Voiceover and Captions
Once you have your video clips arranged, add a voiceover reading your script. Both Canva and CapCut include text-to-speech tools that convert your script into spoken audio. You pick a voice (male, female, accent, tone), paste your script, and the tool generates the audio track.
Text-to-speech voiceovers sound natural enough for most social media ads, though they still have a recognizable AI quality. If your brand voice is very personal or if the ad is for a high-trust product (medical, legal, financial), consider recording your own voice with your phone instead.
For a detailed walkthrough, see how to make an AI voice-over.
Next, add captions. Most social media videos play on mute by default, so captions ensure your message lands even if the viewer never turns on sound. CapCut and Canva both auto-generate captions from your voiceover or let you type them manually.
Use a large, readable font (sans-serif, high contrast) and position captions in the center or lower third of the frame so they don’t cover faces or key product details.
Step 4: Export in the Right Aspect Ratio
Different ad platforms expect different video shapes. Export your video in the aspect ratio that matches where you’ll post it:
| Platform | Aspect Ratio | Use Case |
|---|---|---|
| Instagram Stories, TikTok, Facebook Stories | 9:16 (vertical) | Full-screen mobile ads |
| Instagram Feed, Facebook Feed | 1:1 (square) | Feed posts and carousel ads |
| YouTube, Facebook in-stream | 16:9 (horizontal) | Pre-roll and mid-roll ads |
| Instagram Reels | 9:16 (vertical) | Short-form content |
Vertical video (9:16) gets the most reach on mobile-first platforms. If you’re making one ad for multiple platforms, start with vertical and crop or letterbox for square or horizontal placements.
In Canva or CapCut, select your aspect ratio before you start editing so text, graphics, and key visuals stay within the safe area (the part of the frame guaranteed to show on every device).
Export at 1080p resolution or higher. Most platforms compress video during upload, so starting with high quality ensures the final ad looks crisp.
Safety and Honesty Guidelines
AI makes it easy to create realistic video, but that power comes with responsibility. Follow these rules to stay ethical and avoid legal trouble:
Never use fake testimonials or reviews. Don’t create AI-generated people claiming to have used your product if they’re not real customers. This violates consumer protection laws in most countries and destroys trust if discovered.
Don’t impersonate real people. Using someone’s face or voice without their written consent is illegal in many places and always unethical. This includes celebrities, influencers, and even your own employees if they haven’t agreed to appear in the ad.
Label AI-generated content when required. Many platforms (including Meta, TikTok, and YouTube) require you to disclose when content is AI-generated or significantly altered. Check the ad platform’s policies before you post. Rules vary, but transparency is always safer than silence.
Be honest about what your product does. AI tools can make any product look amazing, but your ad still has to be truthful. Don’t exaggerate benefits, hide limitations, or imply results you can’t deliver.

How Much Does It Cost?
You can make an AI commercial for free using ChatGPT or Gemini for the script, Canva Free or CapCut for video generation and editing, and the built-in voiceover and caption tools. Free plans limit how many videos you can generate per month, and exports may include watermarks.
Paid plans remove watermarks and increase monthly generation credits. Canva Pro, CapCut Pro, and similar subscriptions typically cost between $10 and $30 per month. Check each vendor’s pricing page for current plans and limits, as these change frequently.
If you use API-based video models like Seedance 2.5, you pay per second of video generated. Seedance 2.5 costs from $0.097 per second, meaning a 30-second ad would cost roughly $2.91 in generation fees, not counting script assistance or editing.
Running the ad (paying for impressions or clicks on Facebook, Instagram, TikTok, or Google) is a separate cost and usually the bigger expense. Ad spend varies wildly by industry and targeting but expect to budget at least $5-10 per day to test performance.
Frequently Asked Questions
Can I make a commercial with just my phone?
Yes. CapCut’s mobile app includes script-to-video, text-to-speech, and captioning tools, so you can write, generate, edit, and export a complete ad without a computer. Canva also has a mobile app with video creation features, though the interface is easier on a larger screen. For the script, use ChatGPT or Gemini in a mobile browser or their respective apps.
Do AI commercials work as well as professionally filmed ads?
It depends on your audience and platform. AI-generated ads perform well for direct-response campaigns on social media (clicks, sign-ups, purchases) where viewers scroll quickly and care more about the offer than production value. For brand-building campaigns or high-ticket products where trust is critical, professionally filmed ads with real people still outperform AI-generated ones. Test both if your budget allows.
Which AI video tool should I start with?
Start with CapCut if you want an all-in-one free tool that handles script-to-video, editing, voiceover, and captions. Start with Canva if you already use it for graphics and want to add short AI video clips to your existing design workflow. Both are free to try, so experiment with each and see which interface feels easier for you.
Can I use AI-generated video for ads on Facebook and Instagram?
Yes, but you must follow Meta’s policies on AI-generated content. As of 2026, Meta requires advertisers to disclose when ads contain photorealistic images or video that was AI-generated or digitally altered to show people, places, or events that didn’t really happen. You make this disclosure during ad creation by checking a box in Ads Manager. Failure to disclose can result in ad rejection or account restrictions. Check Meta’s Business Help Center for the latest policy.
How do I make my AI commercial not look like everyone else’s?
Use your own product footage for the hero shot (the main focus of the ad) and let AI generate only the supporting B-roll. Add your brand colors, logo, and fonts in the editing step. Write your script in your own voice rather than using generic AI suggestions word-for-word. The more specific your prompt and the more you customize the output, the less your ad will look like a template.
What if the AI-generated clip doesn’t match my script?
Regenerate with a more specific prompt. Instead of “dog playing outside,” try “golden retriever running on green grass in a park, sunny day, closeup.” Most tools let you generate multiple versions, so create three or four and pick the best one. If none work, film that specific shot yourself with a phone and use AI for the other parts of the ad.
