What they are
DeepSeek
DeepSeek is a large language model chatbot developed by a Chinese AI lab, available free via web, app, and API. Creators, developers, and researchers use it for writing, coding, summarization, and reasoning tasks. Its R1 reasoning model performs competitively with much more expensive alternatives, making it a credible option for budget-conscious creators. Data is processed on servers based in China, which is a real consideration for sensitive content.
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.
