What is HeyGen?

HeyGen is an AI video generator that creates videos from text, images, and audio. It supports explainer videos, marketing and sales promos, product demos, training and onboarding content, personalized outreach videos, and social media clips. Users pick an avatar, enter a script or upload a deck, and choose a voice and language before adjusting visuals and branding, generating the video, and exporting it. The platform combines realistic AI avatars, natural AI voices, and multilingual translation for these video creation workflows.

Key features

  • Creates lifelike AI avatars trained on facial expressions, gestures, and speech patterns to maintain character consistency across video scenes.

  • Offers an AI Studio editor that controls presenter gestures, delivery tone, pacing, and visual layout directly from a text script.

  • Translates and dubs video content into over 175 languages and dialects with voice cloning and synchronized lip movements.

  • Converts PowerPoint and PDF presentations into multi-scene videos featuring AI avatars and synthetic voiceovers.

  • Automatically creates script-based captions with customizable fonts, sizes, and colors.

  • Stores uploaded logos, colors, fonts, images, and videos in a shared Brand Kit.
