What they are
Claude
Claude is an AI assistant from Anthropic that handles writing, research, analysis, coding, and brainstorming through a chat interface. Creators use it to draft scripts, repurpose content, summarize research, and work through ideas. It stands out for following complex instructions and maintaining context across long documents, though it has no live internet access by default and cannot publish or post content directly.
HeyGen
HeyGen generates studio-quality videos using AI avatars and text-to-speech voices, so creators and marketers can produce talking-head content without filming themselves. It supports over 175 languages and lets you clone your own voice and likeness. Teams use it for product explainers, onboarding videos, and localized content at scale. The avatar quality is impressive for scripted material, but unscripted or conversational styles still feel noticeably synthetic.
