Annual plans start at $20/month, which is noticeably cheaper than most multi-model competitors in the $50-100 range.

What Is Synthesys?

Synthesys is a London-based AI video platform founded in 2020 that positions itself as an “AI video agent.” The core idea: instead of forcing every video through one AI model’s limitations, Synthesys selects the optimal model for each scene. Photorealistic avatars from one engine, cinematic motion from another, voice synthesis from a third. The platform composites the results into a single output.

You get UGC ads, product videos, avatar presentations, animated explainers, TV-style commercials, and vertical reel formats for TikTok and Instagram. One subscription covers formats that would normally mean juggling two or three separate apps.

Synthesys reports over 50,000 users and 1,000,000+ videos generated. Enterprise clients include Coca-Cola, Yahoo, and TCS. Third-party ratings sit at Trustpilot 4.4, G2 4.7, and Capterra 4.6.

How Does Synthesys Work?

The workflow follows three steps regardless of which video format you pick.

Synthesys AI Video Generator landing page showing format categories for ads, reels, training videos, and product demos — The AI Video Generator page groups short-form, long-form, talking heads, product demos, and ad formats in one interface.

Pick Your Format and Style

Choose from UGC, product, avatar, animated, commercial, or reel ad templates

Select the video type that matches your goal. Each category has pre-built templates optimized for that format. You can also start from scratch, upload your own character reference, or paste a product URL for the AI to build around.

Add Your Script or Product

Paste a script, drop in a URL, or let the AI generate everything

Three input paths: write your own script, paste a website URL (the AI scrapes it for content), or describe what you want in a single prompt. Synthesys auto-generates the script, selects presenters, and picks the visual style.

Generate and Publish

The AI agent renders your video in minutes

Hit generate and Synthesys routes each component to the right model. Voice synthesis, avatar rendering, b-roll generation, lip-sync alignment, and final compositing happen autonomously. Preview, iterate if needed, and download.

Key Features

Multi-Model Orchestration

Synthesys routes tasks to Sora 2, Google VEO 3.1, Wan 2.5, Kling 3, and SeeDance. New models integrate as they launch - you always have the latest without switching tools.

AI Avatars and UGC Personas

200+ stock video avatars plus unlimited custom UGC personas. Create digital twins from a short recording. Avatars handle corporate, lifestyle, education, and sales use cases.

Voice Engine (1,000+ Voices)

1,000+ AI voices across 175+ languages with frame-accurate lip-sync. Voice cloning and speech-to-speech transformation available on all paid plans.

AI Dubbing (140+ Languages)

Dub any video into 140+ languages with automatic lip-sync. The AI matches mouth movements to each language's phonemes for natural-looking results.

UGC Ad Templates

UGC-style ads built for TikTok, Reels, and Meta feeds. Templates cover news, gaming, wellness, and media verticals.

Recast (AI Face Swap)

New face-swap feature that lets you replace faces in existing videos. Useful for localizing ad campaigns with region-specific presenters.

Hybrid AI VSL

The Video Sales Letter engine is one of Synthesys’ stronger outputs. It combines a presenter avatar with b-roll, screen recordings, and text overlays into explainer-style content up to 2 minutes. Four templates: single avatar sales, mixed media, whiteboard pitch, and product explainer. For coaches, course creators, and SaaS companies that need sales videos without filming, the results land in a usable range.

Product and Brand Videos

E-commerce sellers can upload a product image and get a formatted product ad. Templates cover skincare, streetwear, lifestyle, and tech verticals. The AI handles transitions, music, and pacing. Output quality depends heavily on the input image - clean product shots on white backgrounds produce the best results.

How Credits Work

Credits are the currency for everything on Synthesys. Different video types and AI models consume different amounts.

Credit costs based on 15-second clips. Longer videos consume proportionally more credits. Sora 2 and SeeDance are expensive per-clip.

Video Type (15s)	Credits Per Video	Indie (1,000)	Studio (2,500)	Agency (5,400)
Product Ads	75	13 videos	33 videos	72 videos
VEO 3.1 clips	75	13 videos	33 videos	72 videos
Wan 2.6 clips	38	26 videos	65 videos	142 videos
Commercial Ads	75	13 videos	33 videos	72 videos
Reel Ads	150	6 videos	16 videos	36 videos
Sora 2 clips	975	1 video	2 videos	5 videos
SeeDance 2.0	1,950	0 videos	1 video	2 videos

Sora 2 and SeeDance Credit Costs

Frontier models eat credits fast. A single 15-second Sora 2 clip costs 975 credits - nearly the entire Indie plan’s monthly allocation. If cutting-edge generative video is your main use case, budget for the Studio or Agency plan. Standard models like Wan 2.6 (38 credits) and VEO 3.1 (75 credits) deliver strong results at a fraction of the cost.

Who Should Look Elsewhere

Audience

Why Synthesys May Not Fit

Teams needing top-tier avatar realism

Synthesia's Express-2 avatars are a generation ahead in micro-expressions and naturalness. Synthesys avatars are functional but not the most convincing.

Enterprise with compliance requirements

Synthesia offers SOC 2, ISO 42001, and ISO 27701 certifications. Synthesys has no published compliance certifications for Enterprise.

Developers building integrations

No public REST API, no Zapier/Make integrations. If your workflow depends on automation, look at ElevenLabs or Synthesia.

Content repurposers

No blog-to-video or URL-to-video pipeline. InVideo handles content repurposing and creative generation better.

How Synthesys Compares

Feature comparison as of May 2026. Synthesys leads on price and model variety. Synthesia and InVideo lead on avatar quality and generative breadth respectively.

Feature	Synthesys	Synthesia	InVideo	Fliki
Starting Price	$20/mo (annual)	$18/mo (annual)	$25/mo	$21/mo (annual)
Free Plan	Limited free tier	10 min/mo free	Yes (limited)	Limited free tier
AI Avatars	200+ stock	250+ (Express-2)	Express + clones	Photo avatars (Premium)
Custom Avatars	5-Unlimited (by plan)	Personal avatar (Creator+)	2-40 clones (by plan)	Premium plan only
Voices	1,000+	Not specified	ElevenLabs integration	2,000+
Languages	175+	140+	50+	80+
AI Models	Sora 2, VEO 3.1, Kling 3, Wan 2.5	Veo 3 (b-roll only)	Sora 2, VEO 3.1, Kling 3	Standard models
UGC Templates	Yes (extensive)	No	Limited	No
Video Dubbing	140+ languages	160+ languages	50+ languages	80+ languages
Max Resolution	4K (Agency)	1080p	4K (Max+)	1080p
Commercial Rights	All plans	All plans	All plans	Standard+
Rating	4.2/5	4.7/5	4.7/5	4.3/5

On price alone, Synthesys undercuts most rivals: $20/month annual for multi-model access, versus Synthesia Starter at $18/mo with tight minute caps, Fliki around $21/month, and InVideo at $25/month with a smoother editor. Synthesia still wins if you need SOC 2 paperwork and training workflows.

Avatar quality is the trade-off. Synthesia’s Express-2 presenters look more natural in close-up, with better micro-expressions. Synthesys avatars are fine for ads and social clips, but I would not pick them for a boardroom training video. If you need volume and format variety on a tight budget, Synthesys is the better fit.

Synthesys Pros and Cons

Pros

✓ Multi-model orchestration routes tasks to Sora 2, VEO 3.1, Kling 3, or Wan 2.5 automatically
✓ Lowest entry price ($20/mo annual) for a multi-model AI video platform
✓ 200+ stock avatars and unlimited custom UGC personas on all plans
✓ Full commercial rights at every tier - no extra licensing fees
✓ UGC ad templates are tuned for TikTok, Reels, and Meta feeds
✓ 140+ language dubbing with frame-accurate lip-sync
✓ 1,000+ voice options with cloning and speech-to-speech

Cons

✗ Credit system makes cost-per-video unpredictable, especially with frontier models
✗ Avatar realism trails Synthesia - functional but not the most convincing
✗ No public REST API or automation integrations (Zapier, Make)
✗ Sora 2 and SeeDance clips consume nearly the entire Indie plan's credits in one generation
✗ No published compliance certifications (SOC 2, ISO) for enterprise buyers
✗ Interface can feel template-heavy compared to InVideo's conversational approach

Final Verdict

☆★☆★☆★☆★☆ 0.0

Synthesys fits when you need lots of marketing video formats without enterprise pricing. UGC templates, avatars, product clips, and access to Sora 2 and VEO 3.1 from $20/month annual add up to real value. Avatar realism lags Synthesia, and there is no public API or SOC 2 certification for regulated teams. Buy it for ad volume and format variety; skip it if polished digital humans or compliance docs are non-negotiable.

FAQ

Is Synthesys free?

Synthesys has a limited free tier with a small number of credits to test the platform. It is not a full-featured free plan. For regular video production, the Indie plan starts at $20/month with annual billing ($29/month billed monthly) and includes 1,000 video credits, 5 digital twins, and 10 voice clones.

Is Synthesys worth it in 2026?

For budget-conscious creators who need multi-format video production, yes. Synthesys packs more video formats and AI models into a $20/month plan than most competitors offer at $50+. The main trade-off is avatar quality: Synthesia produces more realistic digital humans. If you prioritize volume, variety, and price over avatar polish, Synthesys is a strong pick.

What AI models does Synthesys use?

Synthesys orchestrates multiple frontier AI models: Sora 2, Google VEO 3.1, Wan 2.5, Kling 3, SeeDream, and SeeDance. The platform automatically selects the best model for each task. New models are integrated as they launch. Credit costs vary by model - standard models like Wan 2.6 cost 38 credits per 15-second clip while Sora 2 costs 975 credits.

How does Synthesys compare to Synthesia?

Different strengths. Synthesia ($18-29/mo) has better avatar realism (Express-2 technology), enterprise compliance (SOC 2, ISO certifications), and interactive Video Agents. Synthesys ($20-29/mo) offers more AI models (Sora 2, VEO 3.1), more video formats (UGC, product ads, commercials, reels), and full commercial rights at every price tier. Choose Synthesia for corporate training and compliance-heavy workflows. Choose Synthesys for marketing video production at scale.

Can I use Synthesys videos commercially?

Yes. Full commercial rights are included on every Synthesys plan, including the Indie tier. You can use generated videos in paid ads, social media, client deliverables, product pages, broadcast TV, and any other business application. No royalties, attribution, or per-video licensing fees. This is an important distinction from some competitors that restrict commercial use to premium plans.

How many avatars does Synthesys have?

Synthesys offers 200+ stock video avatars covering corporate, lifestyle, education, and sales use cases. Beyond stock avatars, you can create custom digital twins (5 on Indie, 15 on Studio, unlimited on Agency) and unlimited custom UGC personas on all plans.
