Synthesys is an AI Video Agent used to turn ideas into finished videos, covering UGC ads, talking-head avatar videos, TV commercials, product demos, voiceovers, and many other formats. Users do not need to hire an agency, book creators, or manage a production team; they only need to describe what they want, and the AI handles scriptwriting, presenter selection, voice generation, lip sync, and rendering.
Use cases Synthesys is positioned as an all-in-one platform to replace traditional video production, suitable for creating social media and UGC videos, sales and explainer videos (VSLs), product and brand videos, AI animated videos, avatar talking-head videos, Reel ads, and TV and YouTube commercials.
Key capabilities The platform integrates multiple cutting-edge AI models for multi-model orchestration, including Sora 2, Google VEO 3.1, Wan 2.5, Kling 3, Seedream, and others. The system selects the most suitable model for each task and automatically integrates new models as they are released. Users can choose from 1000+ AI avatars and 400+ studio-grade voices, with support for 140+ languages and frame-level lip sync, and can also create their own digital twin. Video length is supported up to 30 minutes. The platform provides a large number of templates, covering styles such as news broadcasting, game reviews, health reviews, product sales, whiteboard explainers, animation, corporate executive appearances, TikTok/Instagram Reels ads, and TV-grade commercials. All plans provide full commercial usage rights.
How to use Officially described in three steps: First, choose the format and style. You can choose ready-made templates from UGC ads, product videos, AI avatars, or video sales letters, upload your own character, or start from scratch; second, add a script or product information. You can paste a script, enter a product link, or let Synthesys AI automatically generate all content based on a brief, URL, or a single prompt; third, click generate, preview and download, and publish to any platform without editing software. The platform supports multiple input methods: prompt descriptions, pasting a website URL, uploading product images, or uploading documents.
Applicable scenarios Officially lists three main types of users: e-commerce brands can turn product pages into high-converting video experiences and instantly generate large numbers of product variants; growth agencies can scale client delivery without adding staff and create personalized ad campaigns for each customer segment; content creators can clone themselves and easily produce daily content in multiple languages. Team use cases include marketing and advertising (testing 50 creative variants), training (building a training library with AI avatar videos, where updates only require changing the script), e-commerce (turning product photos into listing videos for Amazon and Shopify), and globalization (creating in one language, dubbing into 140+ languages while maintaining lip sync).
