1. AIアバターライブラリ
ヘイジェン: Offers 700+ stock avatars covering different ethnicities, ages, and styles. The library includes photo avatars, animated mascot options, and talking photos. You can also use custom avatars via the Avatar Pro add-on.
エライ： Provides around 25+ avatars on entry plans and up to 120-160 with higher tiers. The focus is on custom studio avatars rather than a huge stock library. Different avatars are tuned for corporate and educational use.
2. AI Video Maker and Video Generation
ヘイジェン: The video creation process starts with a script or template. Pick an avatar, paste your text, and HeyGen generates a video with auto captions and lip syncing. You can simply upload your script and get a first video in minutes.
エライ： Elai’s video generator turns documents into video. Upload a PPT or PDF and it builds slides automatically. This makes creating videos faster for trainers who already have existing content.
3. AI Cloning and Voice Cloning
ヘイジェン: Voice cloning is an add-on costing about $99/year. You can clone your own voice and use it across talking avatars in multiple languages. The Avatar Pro add-on creates a full custom avatar from your footage.
エライ： Voice cloning is included on paid plans without an extra fee. You get a custom avatar pipeline along with cloned audio. This makes Elai cheaper for teams that need both features.
4. Avatar IV vs Avatar Dialogues
ヘイジェン: Avatar IV produces nuanced head tilts, hand gestures, and superior lip syncing. Micro gestures make talking avatars feel less stiff. This is HeyGen’s biggest edge for high-impact marketing content.
エライ： Avatar Dialogues let multiple AI avatars speak in turn. The realism is good for explainer style content, but micro gestures and facial expression range are simpler than HeyGen’s Avatar IV.
5. テキスト読み上げとAI音声
ヘイジェン: Text to speech runs in 40+ languages with natural sounding ai voices. The platform also supports auto captions and AI dubbing. Useful when you need to localize YouTube videos quickly.
エライ： Text to speech runs in 65+ languages, more than HeyGen. The text to video conversion handles multilingual scripts well. Good for global L&D rollouts.
6. Templates and Video Templates
ヘイジェン: A large template library covers ad formats, explainers, and product demos. Custom templates are available on higher plans. The aim is creating videos for marketing teams.
エライ： Templates focus on training videos, onboarding, and corporate communication. Custom templates are unlocked at the enterprise plan. Less variety than HeyGen for marketing styles.
7. Video Editing and Video Editor
ヘイジェン: The video editor lets you arrange scenes, add captions, and overlay stock footage. Video editing capabilities are simple and aimed at speed rather than depth. Good for short-form video content.
エライ： Elai includes a screen recorder and brand kit alongside the editor. You can mix slide-style content with talking avatars. The editor handles longer training video flows comfortably.
8. Talking Photos and Animated Mascot
ヘイジェン: Talking photos turn a static image into an animated speaker. Faceswap lets you put your face on existing AI avatars. The animated mascot tool helps brands create on-brand video content.
エライ： Elai does not currently match HeyGen’s talking photos or animated mascot features. The focus stays on avatar-driven video generation. If mascot or photo-based talking avatars matter, HeyGen is the stronger pick.
9. Collaboration Features and Team Use
ヘイジェン: The Team plan adds collaboration features for marketing teams. Multiple users can share avatars, brand assets, and templates. The video business plan unlocks higher seat counts.
エライ： Elai’s Team plan and enterprise plan focus on L&D team workflows. Brand kit, custom templates, and a dedicated account manager are unlocked at higher tiers. The video advanced plan suits larger training departments.
