TL;DR: Synthesia is an excellent AI video platform for training, corporate communications, and general marketing—supporting 140+ languages with realistic AI avatars. But for advertising specifically, Benly offers what Synthesia lacks: a 50M+ ad database for competitive intelligence, AI creative generation optimized for ad performance, and cross-platform analytics. Choose Synthesia for internal video. Choose Benly for advertising workflows.

Why Teams Look for Synthesia Alternatives

Synthesia revolutionized video production. Before AI avatars, creating professional presenter videos required studios, actors, and extensive post-production. Synthesia democratized video creation: type a script, select an avatar, and get a polished video in minutes. For training videos, internal communications, and product demos, it's genuinely transformative.

But advertising teams using Synthesia encounter specific friction points:

  • No competitive intelligence: Synthesia creates videos but provides no insight into what competitors are running or what's working in your market.
  • General-purpose, not ad-optimized: Synthesia's AI is trained for corporate video, not advertising. The output feels professional but not performance-optimized.
  • No performance connection: Videos export as files with no connection to ad platforms. You can't see which creative variations drive results.
  • Avatar format limitations: Presenter-style videos work for some ads but not for UGC, product demos, or dynamic creative that dominates paid social.
  • Enterprise pricing for full features: Advanced features require enterprise plans that can exceed $1,000/month for advertising use cases.

These aren't flaws—they reflect Synthesia's design as a general video platform. But advertising teams often need more: competitive research, ad-specific generation, and performance analytics.

Benly as a Synthesia Alternative for Advertising

Benly takes a fundamentally different approach: purpose-built for advertising workflows. Instead of general video creation, Benly connects competitive intelligence, ad creative generation, and performance analytics in one platform designed specifically for paid media teams.

The practical difference: start with the 50M+ ad database to understand what's working in your market, generate on-brand ad creative variations informed by competitive patterns, then track how your ads perform compared to benchmarks—all in one workflow.

Feature Comparison

Competitive intelligence

Synthesia is a creation tool with no competitive research capabilities. You bring your own scripts and ideas—Synthesia doesn't help you understand what competitors are running or what creative patterns drive results in your market.

Benly maintains a 50M+ ad database updated daily across major platforms. Search using natural language: "SaaS demo ads targeting enterprise buyers" or "D2C skincare UGC testimonials." See what competitors run, how long ads stay active, and which patterns appear in top performers.

Bottom line: Synthesia assumes you know what to create. Benly helps you discover what works before you create.

Creative generation approach

Synthesia excels at avatar-based video. Write a script, select a presenter avatar, customize the background, and generate a professional video. The output is polished, professional, and consistent—ideal for training, product tours, and corporate communications.

Benly generates ad creative optimized for performance. Rather than avatar presenters, Benly produces the creative formats that dominate paid social: static ads, carousel variations, video concepts, and UGC-style content. Generate 100+ on-brand variations from a single brief, directly informed by competitive intelligence.

Bottom line: Choose Synthesia for presenter-style video content. Choose Benly for high-volume ad creative production.

Language and localization

Synthesia supports 140+ languages with natural-sounding AI voices. This makes it excellent for global training and communications—the same video can be localized without re-recording. It's a genuine competitive advantage for international organizations.

Benly supports major advertising markets but prioritizes ad platform integration over language breadth. For advertising, the platform coverage (Meta, TikTok, Google, YouTube) typically matters more than 140+ language support.

Bottom line: For global corporate communications, Synthesia's language support is unmatched. For advertising, Benly's platform integration is more relevant.

Analytics and performance

Synthesia provides video analytics (views, completion rates) for videos hosted on their platform. But there's no connection to ad platforms—you export videos and upload to Meta, TikTok, or YouTube separately. Performance tracking requires other tools.

Benly connects directly to ad accounts. See which generated creatives drive results, compare performance across campaigns, and get AI-powered insights on optimization. Natural language queries like "which ad concepts have the best ROAS this month?" return instant analysis.

Bottom line: Synthesia ends at video creation. Benly connects creation to performance measurement.

Enterprise features

Synthesia offers enterprise-grade features: custom avatars, API access, SSO, and dedicated support. For large organizations standardizing on AI video, the enterprise tier provides necessary governance and scalability.

Benly provides team collaboration, white-label options, and dedicated customer success at Scale tier. For agencies managing multiple clients, the multi-account structure and client-facing features address common needs.

Bottom line: Both offer enterprise capabilities. Synthesia focuses on video governance; Benly focuses on advertising workflow management.

Total cost for advertising teams

Synthesia at $89/month appears cheaper than Benly at $99/month. But advertising teams using Synthesia typically also need:

ToolWith SynthesiaWith Benly
AI video/creative generation$89/month (Synthesia)Included
Ad spy/competitive intelligence$49-149/month (Minea, AdSpy)Included
Ad analytics dashboard$72-199/month (Supermetrics, Triple Whale)Included
Static/carousel ad tool$29-99/month (Canva Pro, AdCreative.ai)Included
Total$239-536/month$99/month

For teams focused on advertising, Benly typically consolidates tools and reduces total spend. For teams needing general AI video plus advertising tools, using both may make sense.

Who Should Stay with Synthesia

Synthesia remains the right choice for specific use cases:

  • Training and L&D teams creating employee onboarding, compliance training, and educational content
  • Corporate communications producing internal announcements, leadership messages, and company updates
  • Global organizations needing content in 140+ languages with consistent quality
  • Product teams creating demos, tutorials, and customer education videos
  • Sales enablement producing personalized outreach videos and proposal presentations

Ideal Synthesia customer: An L&D manager creating multilingual training videos, or a product marketer producing consistent product demos without video production resources.

Who Should Switch to Benly

Benly makes more sense when advertising is the primary use case:

  • Performance marketing teams who need competitive intelligence alongside creative production
  • Agencies managing ad campaigns who need to produce high volumes with performance tracking
  • DTC brands running paid social who want creative decisions informed by what's working in their market
  • Growth teams who need to iterate quickly on ad creative with data-driven insights
  • Teams consolidating ad tech stacks who want one platform for spy, creative, and analytics

Ideal Benly customer: A paid media team producing 100+ ad variations monthly who wants to understand competitive patterns, generate on-brand creative quickly, and track what actually drives results.
