No endless tables — just the differences that matter, and a clear call. Pick two tools and see who takes it.
Sora 2
AI Video & Avatars
Sora 2 is OpenAI's second-generation text-to-video model, producing 1080p clips of up to 20 seconds with high physical realism, consistent lighting, and coherent object permanence. Access is bundled into ChatGPT Plus and Pro subscriptions. It is designed for creators and filmmakers who want high-quality video from natural language, within OpenAI's content policy constraints.
Synthesia is an enterprise-grade AI avatar video platform specialising in corporate training, L&D, and internal communications. It provides 230+ photorealistic avatars and a video authoring tool that integrates with existing learning management systems (LMS). Unlike consumer-focused tools, it emphasises governance, brand compliance, and revision workflows suited to large organisations.

Pros
Physical realism — fluid dynamics, object permanence, and lighting consistency are best-in-class

Cons

Plus subscribers get 50 priority generations/month; heavy use exhausts this quickly
Content policy is more restrictive than competitors — certain creative scenarios are refused
No API access — cannot be integrated into automated pipelines
Output cannot be downloaded as separate project files — only MP4 export
