HeyGen

Overview

HeyGen is an AI video generator platform that transforms text, images, and audio into professional videos featuring lifelike AI avatars. The platform eliminates traditional video production requirements like cameras, crews, and studios, enabling users to create content by typing a script and selecting an avatar. HeyGen serves over 100,000 businesses globally and was recognized as G2's #1 Fastest Growing Product of 2025.

The platform's core strength lies in its Avatar IV technology, which generates highly realistic digital avatars with natural voice sync, expressive facial dynamics, and authentic hand gestures. These AI avatars are lifelike enough for professional business content, training videos, and marketing materials, though they have limitations for artistic performances requiring subtle emotional nuance. Users can choose from 700+ stock avatars, create custom avatars from photos or videos, or generate avatars from text prompts. HeyGen's video translator supports 175+ languages with automatic lip-sync, maintaining the original speaker's voice, tone, and pacing across translations—making it a powerful AI translator for video content.

HeyGen targets content creators, marketing teams, L&D professionals, sales representatives, and businesses requiring video localization at scale. The platform can significantly reduce video production costs and shorten production cycles compared to traditional methods, though actual savings vary depending on specific workflows and use cases.

Key Features

• Avatar IV Technology — Fourth-generation AI avatars that transform single images into full videos with natural voice synchronization, expressive face dynamics, and authentic hand gestures, creating highly realistic digital humans suitable for professional business applications.

• Video Translation with Lip-Sync — Translates videos into 175+ languages and dialects while automatically adjusting lip movements to match the translated speech, preserving the original voice characteristics and emotional delivery.

Pricing & Plans

HeyGen offers four pricing tiers designed for individual creators to enterprise teams:

Important Limitations: While Creator and higher plans advertise "unlimited videos," advanced features operate on a credit-based system. Creator plans include 200 generative credits per month and 120 video translation minutes per month. Pro plans include 2,000 generative credits per month (10x more than Creator). High-end features like Avatar IV, advanced AI models, and certain generation capabilities consume these credits, meaning usage is effectively metered despite "unlimited" video creation. Processing speed and feature access also vary by plan tier.

Free Trial: The free plan requires no credit card and provides 3 videos per month (3 minutes each) to test core features before upgrading.

Note: Plan features and limitations are subject to change. Refer to HeyGen's official pricing page for the most current details, as documentation updates may lag behind product changes.
