What they are
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.
OBS Studio
OBS Studio is a free, open-source tool for video recording and live streaming to platforms like Twitch, YouTube, and Facebook Live. It is used by gamers, podcasters, educators, and professional broadcasters who need granular control over their audio and video setup. The feature set rivals paid alternatives, but the interface has a steep learning curve that can frustrate beginners.
