We will explore 10 key features to help you pick the right tool for your video creation needs.
| 特徴 | エライ | キャプションAI |
|---|---|---|
| 開始価格 | 1ユーザーあたり月額23ドル | 月額9.99ドル |
| 無料プラン | ✅ | ✅ |
| Text to Video Generation | ✅ | ❌ |

1. Video Creation Approach
エライ: Elai is a text to video ai video generator. You paste a script and it builds ai generated videos with an avatar reading your words. Its intuitive interface means you skip filming entirely.

キャプションAI: Captions AI flips the model. Instead of generating clips, it edits the video footage you already shot. The AI Creators tools help you film, script, and polish video content in one place.

⚠️ 警告: If you have no footage to start with, Captions AI has nothing to edit. Elai builds videos from text alone.
2. AIアバター
エライ: Elai ships 25 stock avatars plus a custom avatar option. The ai avatars cover many looks for marketing videos and explainer videos. Realism is solid, though human like avatars from Synthesia’s avatars still look a step ahead.

キャプションAI: The ai avatar generator creates realistic ai avatars from short footage. You get custom avatars rather than a library of stock avatars. The result is a realistic ai avatar that matches your own face.

3. Avatar Dialogue and AI Twins
エライ: Avatar Dialogues let two avatars talk in one scene. That suits training videos and workplace learning content where a back-and-forth keeps things engaging. You can even add an animated mascot for lighter explainer videos.

キャプションAI: AI Twins clone you into a digital double. You record once, then generate new personalized videos without filming again. This is handy for a busy youtube channel that needs frequent uploads.

4. キャプションと字幕
エライ: Elai adds subtitles to its ai generated videos, but captions are a basic add-on, not the headline feature. Interactivity tools let viewers click inside training videos, which is rare among video generators.

キャプションAI: Captions are the whole point here. Dynamic captions transcribe and highlight spoken words with eye-catching effects. The auto-captions feel built for social media videos where viewers watch on mute.

5. AI Editing and Shorts
エライ: Elai has no real video editing suite. It generates a finished clip from text, then you tweak slides. A Real-Time Chat avatar can answer questions live, which is a different kind of video creation experience.

キャプションAI: AI Shorts auto-cut long-form videos into shorter clips. The editing features include trimming, B-roll, and screen recording cleanup. For editing videos at speed, the video editor does the heavy lifting.

⚠️ 警告: Elai is not a video editor. If your goal is editing videos, Captions AI is the only real fit between these two AIツール.
6. Voice and Audio
エライ: Elai includes voice cloning, text to speech, and a wide set of ai 声. You can read scripts in multiple languages or upload your own voice. This drives the multilingual videos that suit a global target audience.

キャプションAI: Captions AI also offers voice cloning, but its strongest audio trick is the background noise remover. Clean sound matters more than text to speech when you film with your own voice.

7. テンプレートとカスタマイズ
エライ: A template library and video templates speed up repeat work. The brand kit stores colors, logos, and custom fonts so personalized videos stay on brand. You can even add lottie animations for motion accents.

キャプションAI: Video Customization covers caption styles, custom fonts upload, and custom music. It also supports background removal to swap or clean up backdrops. The choices are tuned for short clips rather than long training videos. It keeps high quality videos looking native to each feed.

8. Stock Media and Assets
エライ: The Stock Media Library bundles stock footage, images, and video assets. You drop these into ai video generation without leaving the editor. It helps you create studio quality videos with no outside downloads.

キャプションAI: AI Edit pulls relevant B-roll and video clips into your timeline automatically. You spend less time hunting for stock footage. The system reads your script and suggests video assets that fit.

9. AI Eye Contact and Polish
エライ: Elai avatars already face the camera, so eye contact is not an issue. The trade-off is that avatars can feel less natural than real footage. For studio quality videos with a human touch, real film still wins.
キャプションAI: AI Eye Contact uses motion tracking to fix your gaze. Even when you read off-screen notes, you appear to look right at viewers. This small touch makes engaging videos feel more direct.

| トップティア | Enterprise: Custom pricing | 料金:月額69.99ドル |
エライ: Elai pricing starts at $23 per month, billed annually. That buys text to video, 25 avatars, and 60+ languages. For training videos, the value is fair, but per-seat billing adds up.
キャプションAI: Captions AI starts at $9.99 per month. It is the cheaper entry point and covers most social media videos. For solo creators, that low price is the deciding factor.
