コロシアンの価格
Colossyan runs on three tiers. Here is the breakdown.
| プラン | 価格 | 最適な用途 |

返金保証: Colossyan does not advertise a blanket refund window. Cancel before renewal to avoid the next charge.
📌 注記： Custom avatars built from your own likeness are a separate purchase at roughly $1,000 per year. Budget for that if you want a branded presenter.

It adds subtitles, fixes eye contact, and cuts dead air.
The app is mobile-first, so you can edit on your phone.
It also generates AI avatar videos from a script.
Creating videos this way skips the whole video production process.
Video creation works in over 65 languages.
This review video covers the editing process step by step.
🏆 受賞者：キャプションAI
Shoot on your phone, then let the AI handle captions, zooms, and cuts. Cheapest entry point of the two.

| プロ | 月額9.99ドル | Solo creators posting short clips weekly |

⚠️ Pricing conflict flagged: Third-party sources quote Captions AI anywhere from $9.99 to $23/month depending on plan and billing cycle. Our table uses the $9.99, $24.99, and $69.99 figures from our own pricing data.
字幕AIの主な利点

- Eye contact correction: The AI redirects your gaze toward the lens. It saves takes where you were reading a script.
- Automatic zooms and cuts: Face detection and scene changes drive the edits. That keeps short videos moving without manual trimming.

- Works on phone and desktop: The mobile app means you can finish a clip between meetings.

- 無料版では、料金を支払う前に試用できます。
- Eye contact correction and AI zooms save editing time
- Video creation in over 65 languages
❌ デメリット

機能比較
Both products get called AI video generators, but the key features barely overlap. Below we walk through nine areas plus cost, so you can see where each one earns its money.
Both ship high quality videos. The difference is what you feed them and what you get back.
| 特徴 | コロサイ | キャプションAI |
|---|---|---|
| 開始価格 | 月額19ドル | 月額9.99ドル |
| 無料版 | ❌（試用版のみ） | ✅（透かし入り） |
| テキストからビデオへ | ✅ | ✅ |
| AIアバター | ✅ 150以上 | ✅ |
| カスタムアバター | ✅（有料アドオン） | ✅（付属） |
| 自動字幕 | ✅ | ✅ |
| アイコンタクト修正 | ❌ | ✅ |
| SCORM / LMS エクスポート | ✅ | ❌ |
| 言語 | 40+ | 65+ |
| 最適な用途 | Training and onboarding | Social media and marketing |
1. テキストからビデオへの変換
コロシアン： Text to video is the whole product. You drop in video scripts, a PDF, or a slide deck, and it builds scenes with a presenter. The video creation process runs entirely in the browser.
キャプションAI: Text to video generation exists here too, under AI Creators. It leans toward short marketing videos rather than long modules. You get amazing videos fast, but less control over scene structure.
Either way, these are AI generated videos, and viewers who watch closely can usually tell.
2. AIアバターとリアリズム
コロシアン： Older documentation listed around 30 AI avatars. Current material puts the library above 150. A custom avatar built from your likeness costs about $1,000 per year.
キャプションAI: The AI avatar generator lets you make a custom avatar without a separate contract. Realistic AI avatars here are tuned for vertical, face-to-camera clips.
⚠️ 警告： Colossyan’s avatar quality does not match Synthesia. If photoreal presenters are the deciding factor, test both free trials first.
3. ビデオ編集機能
コロシアン： Editing means arranging scenes, swapping dynamic backgrounds, and dropping in stock images. The video editor is scene-based, not timeline-based.
キャプションAI: AI Edit does the trimming for you. Face detection drives zooms and scene changes, so raw video footage tightens up in just a few clicks.
4. Background Music and Audio Cleanup
コロシアン： You upload your own background music track per project. There is no built-in library, so bring your own licensed audio.
キャプションAI: The background noise remover matters more here, because you are working with real recordings. Room hum and street noise drop out automatically.
5. AI音声とテキスト読み上げ
コロシアン： More than 600 voice options cover 40+ languages. The text to speech feature lets you correct pronunciation for brand names and acronyms, which matters for training videos.
キャプションAI: AI Twins clones your own voice and face instead of offering a stock catalogue. Text to speech follows your delivery rather than a generic AI model.
6. キャプションと字幕
コロシアン： Subtitles are generated from your script, so accuracy is near perfect. Transitions between scenes stay clean, but caption styling options are basic.
キャプションAI: Auto-captions are the reason people buy this. Styles are animated, brandable, and built for muted feeds. This is where it beats every general-purpose video editor.
7. Short-Form and Interactive Formats
コロシアン： Branching scenarios let a viewer choose what happens next. Nothing in Captions AI does this. It is the strongest argument for workplace learning teams.
キャプションAI: AI Shorts slices a long recording into vertical clips. If your output is social media videos, this saves the most time of any feature here.
8. Recording and On-Camera Fixes
コロシアン： The screen recorder captures software walkthroughs, then pairs them with an avatar narrator. Handy for product training and internal how-to content.
キャプションAI: AI Eye Contact fixes the one thing that ruins talking-head footage. Your gaze snaps to the lens even when you were reading notes.
9. Customization Features and Analytics
コロシアン： Video analytics show who watched and where they dropped off. Paired with SCORM, that is real 報告 for L&D managers.
キャプションAI: Customization features focus on look, not measurement. You control fonts, colours, framing, and video templates, but there is no viewer analytics dashboard.
10. 価格設定とコスト
Here are both price lists side by side.
| ティア | コロサイ | キャプションAI |
|---|---|---|
| エントリ | Starter — $19/month | プロ版 — 月額9.99ドル |
| 中 | ビジネス向けプラン — 月額70ドル | 最大 — 月額24.99ドル |
| トップ | エンタープライズ - カスタム | スケール — 月額69.99ドル |
コロシアン： $19/month buys avatar rendering that would otherwise need a studio. The jump to $70/month is steep for a solo user, and the Enterprise tier is quote-only.
キャプションAI: $9.99/month is half of Colossyan’s entry price, and the top tier is still published rather than custom. Agencies know their ceiling before they commit.
💡 Cost note: Over a year, the entry plans differ by about $108. The bigger cost gap shows up at the top: Colossyan’s Enterprise tier has no published ceiling.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 最低月額料金 | キャプションAI | $9.99 vs $19 entry price |
| Training videos with tracking | コロサイ | SCORM export and analytics |
| 短いソーシャルクリップ | キャプションAI | AI Shorts and animated captions |
| Presenter videos with no camera | コロサイ | 150+ avatars, script-driven |
| Editing on a phone | キャプションAI | Mobile-first app |
| 最も幅広い言語に対応 | キャプションAI | 65+ languages vs 40+ |
💰 あなたの予算
Captions AI opens at $9.99/month and has a free version. Colossyan asks $19/month before you generate videos at all.
🔌 あなたの技術スタック
If you run an LMS, Colossyan plugs straight into it through SCORM. Captions AI has no equivalent hook into learning systems.
📝 あなたのコンテンツスタイル
Structured educational videos and onboarding modules point to Colossyan. Fast, punchy marketing videos point to Captions AI.
🎓 あなたの経験レベル
Neither tool needs video editing experience. Colossyan’s intuitive user interface suits office staff, while Captions AI suits anyone already posting to social feeds.
🆓 無料トライアルとデモ
Both offer free trials, so run the same script through each. Judge the output, not the marketing page.
🛟 サポートオプション
Colossyan’s Enterprise tier includes account support you can escalate to. Captions AI handles support in-app, which is fine for solo users.

私たちのレビューで取り上げられなかったこと
We looked at individual creators and small teams. We did not test Colossyan’s Enterprise tier, SSO, or bulk licensing, and we did not measure render times at volume across long projects. Image generation quality and API access sit outside this comparison too. If you manage 50 or more seats, your priorities will differ from what we covered here.

🏆 受賞：キャプションAI
Captions AI takes 4 of 7 categories.
最適な用途: Social media videos, promotional videos, creators editing on mobile
Captions AI wins on price, reach, and speed. It costs half as much to start, covers 65+ languages, and turns raw footage into professional looking videos with very little work.
If your goal is high quality video content for feeds and ads, it gets you there with fewer steps. Both AI tools can create professional videos, but only one of them was designed for the phone in your pocket.
Colossyan is not the loser in every room. For workplace learning it is the stronger AI video platform, because SCORM export, branching scenarios, and video analytics have no counterpart in Captions AI.
If your job is to publish engaging videos every week, pick Captions AI. If your job is to train staff and prove they watched, pick Colossyan.
