Frequently asked questions

What is the difference between ChatGPT and specialist script generators?

ChatGPT is a general-purpose language model excelling at dialogue and narrative flexibility but requiring more user direction. Specialist tools like Runway AI and HeyGen integrate script generation with video production, avatar rendering, and multilingual support, making them better for creators wanting end-to-end automation from text to polished video output.

Can these tools replace professional screenwriters?

AI script generators excel at generating first drafts, story structures, and marketing copy rapidly. However, professional screenwriters bring artistic vision, emotional depth, and original storytelling that AI currently cannot fully replicate. Most professionals use these tools to accelerate brainstorming and revision rather than as full replacements.

Which tool is best for multilingual video content?

HeyGen is the strongest choice for multilingual content, supporting 100+ languages with culturally authentic avatars and professional voice synthesis. Synthesia also offers strong multilingual support with 140+ languages. Both enable rapid localisation without hiring talent for each language.
