HeyGen — KI-Videogenerator und sprechende Avatare

HeyGen is arguably one of the most advanced platforms for creating professional videos driven by artificial intelligence. Founded on the belief that "stories shape our world," the California startup enables over 15 million users to produce more than 37 million videos without ever stepping in front of a camera. At the heart of HeyGen: AI avatars. With over 1,100 ready-to-use avatars, infinitely customizable (expressions, gestures, outfits, backgrounds), the platform offers unprecedented variety. Avatar IV, its latest model, turns a single photo into a smooth video with precise lip-sync, natural expressions, and authentic hand gestures. You can also create your own digital twin (Video Avatar) from a short filmed sequence, or generate unlimited avatars from a single image and text instructions (Photo Avatar, Generative Avatar). Video creation revolves around three main modes. Text-to-video: type a script, choose an avatar and voice, and HeyGen produces a complete 1080p or 4K video with voiceover and coherent visuals. Image-to-video: upload a photo, add text to pronounce, and the AI animates the image with perfectly synced lip movements. Finally, video translation: upload an existing video and translate it into over 175 languages and dialects, preserving the voice, tone, and lip-sync of the original speaker. This last feature reportedly reduces translation costs by about 80%. HeyGen's AI Studio, its text-based editor, drastically simplifies editing. No more complex timeline: you work as on a document, adjusting tone, gestures, and emotions directly in the script. The platform also offers a Chrome extension to turn voice recordings into videos, an API to integrate generation into your workflows, and advanced features like product placement (inserting products into scenes with natural avatar interaction) or styled caption generation. Use cases span a very broad spectrum. In training and development: compliance videos, tutorials, large-scale onboarding. In marketing: explainers, promos, personalized content for campaigns. In sales: video prospecting, product demos, personalized follow-ups. In localization: adapting videos for international markets in minutes. Content creators use it for visual podcasts, Reels, TikTok, or YouTube Shorts. Support teams deploy virtual presenters for FAQs or chatbots. Miro, one of the featured customers, reports a 10x increase in video production speed and a 5x increase in content creation. HeyGen is certified GDPR, SOC 2 Type II, CCPA, AI Act, and DPF, ensuring secure and compliant use in professional environments. A free plan allows testing text-to-video and basic creation; paid plans provide access to advanced avatars, translation, API, and advanced editing options.
