What they are
Gamma
Gamma is an AI presentation and content platform that turns a prompt, outline, or pasted document into a presentation, webpage, or document using a fluid card-based format rather than fixed slides. It targets marketers, educators, consultants, and small business owners who need polished visual content without a designer. Outputs publish directly as web pages or export to PowerPoint, PDF, and Google Slides. The free tier is genuinely usable for testing, but its 400 non-refilling credits mean most regular users will need a paid plan.
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.
