How to Create Facebook Ads with AI in 3 Steps
From concept to campaign in under 2 minutes.

Upload a product image or describe your offer. AI analyzes key benefits and features to build a creative brief automatically.
- 2

Generate & Launch
AI creates your video ad with voiceovers, avatars, and captions. Edit, refine, and export directly to Ads Manager.
Every Meta Placement, One Upload
One product image becomes platform-ready ads for every surface Meta offers. No reformatting, no cropping, no guessing specs.
Feed & In-Stream
16:9 horizontal and 1:1 square formats optimized for Facebook and Instagram feeds. The AI adjusts framing, text overlay placement, and presenter positioning so your ad looks native in-feed — not like a repurposed TV spot. Compression-optimized to stay sharp after Meta's encoding.
Stories & Reels
9:16 vertical format built for full-screen immersion. Auto-captions baked in, hook-first pacing, and the casual creator energy that Stories and Reels reward. Works identically for Instagram Reels placements — and exports ready for TikTok Ads if you're running cross-platform.
Carousel & Collection
Generate multiple creative angles from one product — different hooks, features, or use cases per card. Each card is a standalone video ad that works in sequence or alone. Ideal for product catalogs, feature breakdowns, and A/B testing creative angles without producing each one separately.

How realistic do AI Facebook video ads look?
Realistic enough to blend into the feed alongside organic creator content. The AI produces natural delivery with genuine expressions, casual pacing, and the kind of off-the-cuff energy that Meta's algorithm rewards. This isn't overproduced brand content that screams "ad" — it's the format users actually engage with before realizing it's AI-generated. The system is trained on high-performing Facebook ad creatives, so it understands what stops the scroll on this specific platform: eye contact in the first frame, a hook within 3 seconds, and a delivery style that feels like a friend recommending something, not a spokesperson selling it.
Can I create Facebook and Instagram ads together?
Yes — one upload produces every Meta placement. Feed ads for Facebook and Instagram in 1:1 and 16:9 formats, Stories in 9:16 vertical, Reels-ready content with auto-captions, and formats sized for the Audience Network. You don't manage separate projects per placement. Upload your product once, and the system generates platform-specific versions that respect each placement's specs, safe zones, and best practices. This also means A/B testing is faster — create 10 variations and deploy across every Meta surface simultaneously instead of producing each format individually.
What video formats are supported?
All core Meta placements. 9:16 vertical for Stories and Reels, 16:9 horizontal for feed and in-stream, and 1:1 square for versatile feed placement. Each format is compression-optimized specifically for Meta's encoding pipeline, so your ads stay sharp after upload — no pixelation, no quality loss on the text overlays that plague videos optimized for other platforms. Exports are MP4 with file sizes tuned to fall within Meta's recommended specs for fast delivery. If you're also running ads on TikTok or YouTube, you can export those formats from the same project without re-generating.
Does this work as a Facebook video ad generator?
That's its primary function. Every ad includes a video component — a virtual presenter delivering your product message in creator-style format, with natural lip-sync and expressions. The system is purpose-built for video-first advertising because that's what Meta's algorithm prioritizes: video ads get 2-3x the reach of static images in most verticals. You get feed videos, Story videos, and Reels-ready content from a single generation. The AI handles script writing, presenter selection, pacing, captions, and export — you just provide the product details and choose your style.
What ad styles work best on Facebook?
Five formats consistently outperform on Meta. Creator testimonial (the "I tried this" format) works best for cold prospecting — it feels like organic content and earns engagement before viewers realize it's an ad. Product demo converts bottom-funnel traffic by showing the product in action. Problem-solution builds awareness by naming the pain point first. Unboxing creates anticipation and social proof. Discovery style ("I just found this product and had to share") drives impulse clicks. Each template is structured around these approaches, not generic corporate formats that get tuned out. You can generate all five from one product upload and let your ad spend determine the winner.
What languages are supported?
Over 140 languages with native-sounding delivery — not machine-translated voiceovers layered on top. The AI matches pronunciation, pacing, and emotional tone to each language, so a German version sounds like a German creator recorded it, not a translated English script. This covers all major Meta advertising markets: US and UK English, Spanish (Latin American and European), French, German, Portuguese, Japanese, Chinese, Arabic, Hindi, and dozens more. For international brands, you create one winning ad concept and deploy it across every target market. No separate productions, no multilingual talent sourcing, no per-language creative briefs.
How fast can I create a Facebook ad?
Most ads render in under 5 minutes. The workflow is: upload your product image or paste a URL, select your ad style and presenter, review the AI-generated script, and hit generate. During high-traffic periods the app shows your queue position so you're not guessing. For comparison, a traditional Facebook video ad takes 1-2 weeks from brief to delivery, and even basic editing tools need hours of manual work. If you're testing multiple creative angles (which you should be — Meta rewards fresh creatives every 7-14 days), you can produce a week's worth of variations in a single sitting.
Can I use these ads commercially?
Full commercial rights on every Synthesys plan — this isn't a freemium trap where commercial use requires an upgrade. Run ads through Facebook Ads Manager, Instagram Ads, post organically, embed on your website, include in email campaigns, or use in client deliverables if you're an agency. The license is perpetual with no usage caps, no royalties, and no attribution requirements. Some competing tools restrict commercial use or charge per-video licensing fees. Synthesys doesn't — everything you generate is yours to use across any channel, for any purpose, for as long as you want.
