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.
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
