Comparaison des fonctionnalités
Ready to dive into a detailed Synthesia vs Synthesys comparison?
We’ll explore eight key features to help you decide which platform fits your video creation goals.
| Fonctionnalité | Synthesia | Synthesys |
|---|---|---|
| Prix initial | 18 $/mois | 20 $/mois |
| Plan gratuit | ✅ | ✅ |
| Avatars IA | ✅ (230+) | ✅ (smaller pool) |
| Bibliothèque vocale | ✅ | ✅ (400+ voices) |
| Custom Models | ✅ (Entreprise) | ✅ (limité) |
| Langues prises en charge | 140+ | Plusieurs langues |
| Importation PowerPoint | ✅ | ❌ |
| Photos parlantes IA | ❌ | ✅ |
| Dynamic Gesture Control | Limité | ✅ |
| SOC 2 Type II | ✅ | ❌ |
| Idéal pour | Training, global teams | Voice-heavy content |
1. Avatars IA
Synthesia : Synthesia offers 230+ AI avatars across ages, ethnicities, and outfits. The avatars produce natural facial expressions and gestures while reading your script. According to G2 reviews, the avatar quality is one of the most praised parts of the platform for training videos.
Synthesys : Synthesys calls its avatars “AI Humans” and ships a smaller library than Synthesia. The trade-off is dynamic gesture control, which lets you tweak how the AI human moves on screen. That can produce more dynamic results for product demos.
2. Génération vocale
Synthesia : Synthesia includes solid text-to-speech tied to each avatar’s voice. The voices sound natural in English and most major languages. The platform is built around video first, so voice generation supports the avatar rather than acting as a standalone product.
Synthesys : Synthesys ships 400+ AI voices with voice cloning baked in. You can pick specific voice tones — calm, excited, neutral — without recording extra takes. For voice-first creators, this library is the main reason to pick Synthesys.
3. Language Support and Translation
Synthesia : Synthesia supports 140+ languages with one-click video translation. This makes Synthesia a fit for global teams running training in many regions. The platform handles script, voice, and subtitles together — useful when running a translation project across regions.
Synthesys : Synthesys supports multiple languages but covers fewer regions than Synthesia. The audio translations feature is its strongest multilingual tool. For voice-only output across languages, it works well — for full localized video at scale, Synthesia goes further.
4. Video Editor and User Interface
Synthesia : The video editor uses a clean, slide-based layout. Each scene works like a slide, which makes the platform feel familiar to users who already build PowerPoint presentations. The user interface is built for non-editors who want to create content fast.
Synthesys : The Synthesys editor groups voice, video, and image tools in separate workspaces. The user interface takes a bit longer to learn for first-time users. Once you get past the initial setup, the controls feel flexible — especially around voice fine-tuning.
5. Customization Features
Synthesia : Customization features in Synthesia cover scenes, brand kits, on-screen text, and basic shapes. Enterprise users can also create custom models — including custom AI clones of real employees. That makes branded training videos far easier to produce at scale.
Synthesys : Synthesys focuses customization on voice tone, gesture control, and avatar style. The Face Form feature lets you adjust how an AI human’s face appears on screen. Customization runs deep on voice and motion, but lighter on full scene templates.
6. PowerPoint and Asset Import
Synthesia : Synthesia lets you upload PowerPoint presentations and turn each slide into a narrated AI video. This is a big time-saver when repurposing existing training decks. The import works well for course creators moving from static slides to AI video.
Synthesys : Synthesys does not offer direct PowerPoint import in the same way. You can upload assets like images and scripts, but slide-by-slide conversion is not the focus. For deck-driven training content, this is a real gap compared to Synthesia.
⚠️ Avertissement: If your team already runs training off PowerPoint presentations, Synthesia saves you a manual rebuild step. Test the import on a real deck before committing.
7. Sécurité et conformité
Synthesia : Synthesia meets SOC 2 Type II compliance. That fits the higher security standards preferred by mid-to-large sized businesses. Verification successful waiting screens, secure share links, and SSO support give IT teams more control over who sees what.
Synthesys : Synthesys does not advertise the same SOC 2 Type II posture publicly. Standard account security and HTTPS are in place, and a Cloudflare Ray ID may appear if the site properly blocks suspicious traffic. For teams in regulated industries, the gap matters.
8. Tarification et coût
Comparons les plans tarifaires côte à côte.
| Plan | Synthesia | Synthesys |
|---|---|---|
| Gratuit | Plan gratuit disponible | Essai gratuit disponible |
| Entrée / Débutant | Starter — $18/month | Personal — $20/month |
| Niveau intermédiaire | Creator — $64/month | Creator — $41/month |
| Niveau supérieur | Enterprise — Custom Pricing | Business — $69/month |
Synthesia : Synthesia’s $18 Starter is the cheapest entry point in this comparison. The jump to the $64 Creator plan is steep, but you unlock more video minutes and better team features. Enterprise pricing is custom — fit for companies needing custom models and SSO.
Synthesys : Synthesys starts $2 higher than Synthesia at $20/month. The mid-tier Creator plan at $41/month is cheaper than Synthesia’s mid-tier. The Business plan caps at $69/month and is fully transparent — no need to talk to sales.

What Our Review Didn’t Cover
This Synthesia vs comparison focused on solo creators, marketers, and mid-sized teams. We did not stress-test enterprise SSO setups or evaluate translation API glossary controls in depth. We also didn’t run the AutoML translation pipeline at scale or test how the Seaplace Group and similar localization vendors plug in. Custom Enterprise pricing for both tools also wasn’t part of this review. If you’re shipping training videos for tens of thousands of paying customers — or planning the rollout as your next job in L&D — your priorities and contract terms may differ from what we’ve covered here.

Foire aux questions
Qu'y a-t-il de mieux que Synthesia ?
For most use cases, Synthesia is hard to beat thanks to its avatar quality and language reach. HeyGen is a strong alternative for faster custom avatars, while Colossyan is a fit for branching scenario videos. The best option depends on whether you value language coverage, avatar realism, or training-specific features.
Synthesia est-il totalement gratuit ?
No. Synthesia offers a free plan with limited monthly video minutes, but full access requires a paid plan starting at $18/month. The free plan is enough to test avatars and basic editing on short clips. Heavy users will outgrow it quickly.
What is the difference between synthesis and synthesize?
“Synthesis” is the noun and “synthesize” is the verb. Synthesis combines multiple sources into new insights, while synthesizing is the act of doing it — interpreting données and producing dynamic results rather than just restating one source. In tools like Synthesia and Synthesys, that idea applies to combining script, voice, and avatar into one video.
What are the two types of synthesis?
In academic writing, the two types are explanatory synthesis and argumentative synthesis. Explanatory synthesis explains a topic using multiple sources, while argumentative synthesis builds a position by weighing connections, trends, or contradictions. Program synthesis is a separate concept where artificial intelligence generates computer code from examples or natural language.
Which is the best AI video creation platform?
Based on this comparison, Synthesia wins overall for AI video. It offers more avatars, more languages, and stronger security. Synthesys is the better pick if voice generation, AI talking photos, or gesture control are your top priorities.
