Reviewers mostly praise HeyGen for realistic avatars, easy video creation, and useful translation and dubbing tools, with several saying it saves time, lowers production costs, and fits well into content, course, and marketing workflows. Some also note specific limits: voices can sound flat, scripts need tuning, templates feel dated, and processing can be slow. The sharpest criticism is about operations, not output: multiple users report weak support, confusing plan changes, moderation delays, rejected videos, and disputed credit or billing practices.
