What they are
Google Gemini
Google Gemini is a conversational AI built on Google's large language models, capable of text generation, summarization, coding help, and image understanding. Creators use it for drafting scripts, brainstorming ideas, and researching topics without leaving a chat interface. The free tier is genuinely useful, and the Advanced plan unlocks Google's most capable model. Deep integration with Google Workspace is a real advantage for creators already in that ecosystem.
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.
