HeyGen is an AI video platform centred on avatars: digital presenters, including one modelled on yourself, that deliver a script on screen. Its current avatar model, Avatar V, is designed to keep one identity consistent across angles and videos. A Video Agent turns a written idea into a finished video, and AI Studio is a text-based editor in which wording, delivery and gestures are adjusted like a document. Video Translation re-voices footage with voice cloning and lip-sync in more than 175 languages and dialects. Other inputs include images, audio files and PPT or PDF decks. Custom avatars require on-camera identity verification from the person shown. APIs are available for developers, and paid plans run on monthly credits. ## Key features - **AI Avatars**: Generates presenter footage from stock or custom avatars, with consistent appearance across wide, medium and close-up shots. - **Video Agent**: Builds a complete video from a prompt, including presenter footage, motion graphics and B-roll that remain editable afterwards. - **AI Studio**: Edits video through its script, with controls for tone, pacing and gestures, plus comments and multi-user editing for teams. - **Video Translation**: Translates an uploaded file or a YouTube link into other languages while keeping the speaker's voice and syncing the lips. - **Multiple Input Types**: Starts a video from text, an image, an audio recording or an imported PPT or PDF. - **Trust and Safety Controls**: Requires verified consent for custom avatars, moderates generated content and lists SOC 2 Type II, GDPR and CCPA. ## How HeyGen works 1. **Pick an avatar**: Choose a stock avatar or one you have created. 2. **Add the script**: Paste the text the avatar should say, or upload a slide deck instead. 3. **Choose voice and language**: Select the voice and the language for the narration. 4. **Adjust and export**: Tune visuals and branding, generate the video and export the finished file. ## Use cases - **Training and Onboarding**: Produce course modules and internal learning videos with an on-screen presenter instead of booking a shoot. - **Marketing and Product Demos**: Create explainers, promos and product demonstrations from a script without a camera or crew. - **Localising Existing Video**: Upload a finished video or paste a YouTube link and release it in other languages with the original voice. - **Personalised Sales Outreach**: Send presenter-led video messages to prospects as part of a sales sequence. - **Slides to Video**: Import a PPT or PDF deck so that each slide becomes a narrated scene. ## Things to know - **Custom avatars need identity verification**: The person shown must verify their identity on camera before a custom avatar is created, and removal requests are honoured. - **Free plan limits**: The Free plan covers 3 videos a month of up to one minute each. - **Credits stop rolling over after cancellation**: Once a subscription is no longer active, credits from the previous cycle expire. ## FAQs ### What is HeyGen?
