HeyGen vs Synthesia vs Vidext: The Final Verdict for Spanish Companies
All three tools generate AI avatar videos. All three have broad voice catalogs, import presentations, and show up in the same search when someone from HR or L&D starts researching. But that's where the similarities that actually matter end.
These platforms have different origins, product focuses, and business models. HeyGen was built for creators and marketing teams. Synthesia was designed with large English-speaking enterprises in mind. And Vidext was built specifically for the operational reality of industrial, service, and regulated-sector companies in the Spanish and Spanish-speaking market.
This comparison looks at all three through criteria that matter when video is for internal training, not social media: which plans include SCORM, how billing works, what certifications they hold, and what support looks like after you sign the contract. The goal is a useful verdict, not a generic feature checklist.
80% of corporate video in Spain is internal training. Not marketing, not external comms: training. That completely changes what a tool needs to do to be useful in that context.
Generating professional-looking videos isn't enough. You need to export them to your LMS in SCORM or xAPI format to track completions, keep them updated when a procedure or regulation changes, meet the traceability requirements of workplace safety training, and be able to audit them if a labor inspection requires it. None of those criteria show up in these platforms' product demos.
The real cost of the wrong decision doesn't surface until after you've signed. A tool that doesn't include SCORM in the plan you bought forces you to upgrade or export videos without completion tracking. A platform that bills in dollars without a Spanish fiscal entity creates accounting friction you didn't plan for. Support that doesn't speak Spanish stretches every incident longer than it should.
Five criteria worth clarifying before comparing features in the Spanish market:
With those criteria as the baseline, the HeyGen vs Synthesia vs Vidext comparison tells a very different story than most articles in this space.
HeyGen has some of the best lip-sync technology on the market. That's not accidental: the company built its value proposition around the ability to automatically dub and localize existing videos, preserving the original presenter's lip sync in any language. For that specific use case, it's hard to beat.
The challenge for training departments is that the platform is built with creators, marketing teams, and use cases where the original video already exists in mind. The creation of structured corporate training from scratch, with branching, modules, and LMS export, is not the center of gravity of the product.
In terms of pricing, HeyGen includes SCORM export starting with the Business plan at $149/month. The Creator ($29) and Pro ($99) plans don't include SCORM. Billing is in USD with no Spanish fiscal representation.
That said, there are clear cases where HeyGen makes sense for a Spanish company: if you already have an English video library that needs to be localized into Spanish, Catalan, or other languages with dubbing quality, HeyGen is the most efficient tool for that specific job. Its language catalog covers 175+ languages including regional Spanish variants.

Synthesia is the sector's historical reference. It was the first platform to popularize AI avatar video generation for corporate training and remains the most mature option for large companies producing training primarily in English.
Its catalog of 240+ avatars is the largest in the industry. It has mature integrations with the leading LMS platforms (Cornerstone, SAP SuccessFactors, Degreed, among others) and a large user community, which translates into extensive documentation, forums, and resources.
For the Spanish market, two things are worth noting. The first is positive: Synthesia has significantly expanded its language support and now covers Catalan, Basque, and Galician, alongside multiple Spanish variants. The second is more structural: the platform is built with the global English-speaking customer as its primary profile, and that shows in support, published case studies, and product roadmap direction.
On SCORM: available from the Creator plan ($89/month), making it more accessible than HeyGen. Enterprise pricing starts at around $15,000/year based on publicly available data. Billing in USD without a Spanish invoice.
Synthesia is the coherent choice for a multinational company headquartered in Spain that manages training primarily in English or for globally distributed audiences. If the context is internal training for employees in Spain, with local compliance needs and Spanish billing requirements, the fit is weaker.

Vidext doesn't compete in the same segment as HeyGen or Synthesia by design. The proposition isn't "generate AI videos more easily" but converting a company's accumulated operational knowledge (SOPs, manuals, procedures, presentations) into scalable, auditable video training. That's what we call Knowledge Infrastructure.
From a practical features standpoint for the Spanish market, the differentiators are:
SCORM and xAPI available on all plans, not just higher tiers. For a training department that needs to track completions from day one, this removes a significant friction point and reduces the real cost of adoption.
Billing in EUR with a Spanish invoice and VAT. It seems like a detail, but for mid-sized companies with procurement processes in Spain, the difference between a Spanish invoice and a dollar-denominated one from a US company can add weeks to an approval process.
ISO 27001 certification and National Security Framework (ENS) at medium level. The ENS is the cybersecurity reference framework for Spanish public administration and increasingly a preference criterion in regulated sectors (healthcare, industry, critical infrastructure). It's the only one of the three platforms with this certification.
Customer Success Manager included on all contracts, with dedicated onboarding of four sessions plus monthly follow-ups. At Synthesia and HeyGen, personalized support is generally reserved for enterprise contracts.

There is no universally better tool. The common mistake in this kind of decision is looking for the "best platform" in the abstract rather than the right platform for the specific context. Here are three profiles with a direct recommendation.
Profile A: multinational company, training primarily in English, global audiences
If the bulk of your training production is in English and you have employees distributed across multiple countries with different languages, Synthesia is the most mature option. It has the largest avatar catalog, consolidated integrations with the leading global LMS platforms, and a user community large enough that most problems already have a documented solution somewhere. The Spanish billing limitations are real but manageable for this profile.
Profile B: company with an existing video library that needs multilingual localization
If you already have produced videos (product tutorials, sales training, corporate videos) and the goal is to localize them into multiple languages while maintaining dubbing quality, HeyGen is the most efficient tool for that specific use case. Its lip-sync technology is built for this and delivers on what it promises. SCORM restricted to higher plans is a factor to consider, but for localizing already-produced content it's not a blocker.
Profile C: Spanish company with operational training, compliance, or regulated sector
If you produce internal training in Spanish for employees of a Spanish company (workplace safety, operational processes, onboarding, quality, compliance), need SCORM from day one, invoices in EUR, and someone who understands the local context, the combination of ENS, ISO 27001, SCORM on all plans, and Spanish billing that Vidext offers is not available on the other two platforms in their standard configuration.
Document Inertia (the organizational tendency to keep manuals in PDF even though nobody reads them) is the underlying problem in many Spanish companies. HeyGen and Synthesia are good options for creating new video from a blank slate. Vidext is built specifically to convert accumulated documentary knowledge into scalable video training, without the training department having to start from scratch every time a procedure changes.
The corporate training with AI market is worth $400 billion globally and 74% of companies acknowledge they're not keeping up with their teams' skill development needs³. The tool you choose won't solve that challenge alone, but choosing the wrong one makes it harder than it needs to be.
HeyGen, Synthesia, and Vidext are serious platforms that do well what they promise. The question isn't which one is best, but which one fits your actual operational criteria.
For localizing existing video: HeyGen. For English-language training with global audiences: Synthesia. For operational training in Spanish with compliance, SCORM from the first plan, and local billing: Vidext.
If you have questions about what each option means in terms of LMS integration, SCORM setup, or migrating from another platform, the article on Synthesia alternatives for internal training in Spanish and the HeyGen vs Vidext comparison have more technical context for each case.
HeyGen specializes in lip-sync and localizing existing videos, positioned primarily for content creators and marketing teams. Synthesia is the pioneer in corporate training with AI avatars, with the largest avatar catalog in the sector and greater orientation toward enterprise L&D. Both bill in USD and have SCORM available only from mid-tier plans or higher.
All three platforms support Spanish, Catalan, Basque, and Galician. The real difference is in the rest of the package: Vidext is the only one with EUR billing and a Spanish invoice, National Security Framework (ENS) medium level for regulated sectors, and SCORM available on all plans from the start.
Only Vidext includes SCORM and xAPI export on all its plans. Synthesia offers it from the Creator plan ($89/month) and HeyGen from the Business plan ($149/month). If SCORM is a requirement from day one, this directly determines the real cost of each option.
Workplace safety (PRL in Spain) requires traceability (SCORM/xAPI to record completions), auditability, and in industrial contexts or those with public administration contracts, security certifications recognized in Spain. Vidext is the only one of the three with ENS medium level, making it the most suitable for companies in industrial, healthcare, or public sector adjacent industries.
Yes. The transition typically involves reusing existing content and adapting SCORM packages to the new workflow. There's a technical Synthesia-to-Vidext migration guide with the step-by-step process, including managing completion records in the LMS.
