Most people picking an AI video generator start from the wrong 質問.
They ask which tool makes the prettiest video.
The better question is what you plan to do with the video.
Colossyan was built for workplace learning content.
Synthesys started as a voice company and grew into video.
That difference shapes almost everything below.
概要
This Colossyan vs Synthesys comparison covers pricing, features, and ease of use.
We also break down who each AI video generator fits best.
弊社のライター陣は、両方のプラットフォームを実際に操作して検証しました。
それらのメモは、以下の「チームが気づいたこと」のセクションに記載されています。
Everything else comes from published specs, documentation, and G2 reviews.
⚠️ Name check: Synthesys (with a “y”) is not Synthesia. They are separate companies with separate products. Synthesia is a bigger enterprise avatar platform and shows up later in the competitor section.
コロサイとは何ですか？
Colossyan is an AI video tool that turns text into professional videos.
It was built specifically for workplace learning content.
Think employee onboarding, customer education, and internal communication.
You write a script, pick an avatar, and press generate.
No prior video editing experience is needed.
The avatars recite your script in many accents and languages.
Here is a walkthrough of how the platform works.
🏆 Winner: Colossyan
Turn documents and scripts into training videos with AI avatars. Add quizzes, branching, and analytics without leaving the editor.
コロシアンの価格
Colossyan runs on three plans. Here is the breakdown.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| スターター | 月額19ドル | ソロクリエイターがAIビデオをテスト |
| 仕事 | 月額70ドル | L&D teams needing unlimited video minutes |
| 企業 | カスタム | Large rollouts with API access and SSO |
Pricing verified August 2026.
無料トライアル: Yes. You can generate sample video clips before paying.
返金保証: No published refund window. Cancel before renewal instead.
📌 注記： The Business plan is the one L&D teams usually land on. It removes the minute ceiling, which matters when you rebuild the same course in eight languages.
⚠️ Pricing conflict: Our research notes mention a free Colossyan plan with 3 minutes per month. Our CSV pricing data lists only Starter, Business, and Enterprise. We publish the CSV figures above. Check the vendor page before you budget.
Colossyanの主な利点
Here is what makes Colossyan worth a look:
- Document to video: Drop in a PowerPoint, PDF, or Word file. Colossyan returns a video draft you can edit.
- Multiple speakers: Place two or more avatars in one scene. That lets you stage simulated interviews and coaching dialogue.
- インタラクティブな要素: Multiple-choice quizzes, branching scenarios, and clickable hotspots are built in.
- SCORM export: Push finished courses straight into your learning tech stack.
- One-click translation: Around 70 to 80 languages are covered by the translation tool.
- メディアライブラリ: Stock images, stock videos, animations, and music sit inside the editor.
- Full commercial licensing: Videos can run in paid campaigns without extra clearance.

Synthesysとは何ですか?
Synthesys is a voice-first AI video maker.
The company built its name on high fidelity AI voices.
Video came later, layered on top of that audio work.
You paste a script and pick a voice and an AI human.
The result is a talking presenter with a matching voiceover.
It also makes still photos talk, which most video generators skip.
This walkthrough shows the editor in action.
準優勝：シンセシス
Strong AI voices with video and image tools attached. A fit if audio quality matters more to you than course structure.
シンセシスの価格
Synthesys also runs three tiers. Here is the layout.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 個人的 | 月額20ドル | フリーランサー who mostly need voiceovers |
| クリエイター | 月額41ドル | YouTubers and marketers making video content |
| 仕事 | 月額69ドル | Small teams needing volume and API access |
Pricing verified August 2026.
無料トライアル: A limited free tier lets you sample voices before you commit.
返金保証: No standing guarantee is published. Downgrade or cancel inside the dashboard.
📌 注記： The jump from Personal to Creator is the real decision point. Personal suits audio-only work. Creator is where the video features open up.
⚠️ 警告： G2 reviews flag cancellation as a common friction point. Cancel from the account settings and keep the confirmation email.
Synthesysの主な利点
Here is where Synthesys earns its keep:
- Voice depth: The text to speech feature produces realistic and engaging voiceovers across dozens of accents.
- 音声クローン: Upload samples and the system builds a custom voice you own.
- AIが話す写真： A single headshot becomes a speaking presenter.
- シンセシス・ラボ： AI image generation sits beside the video tools, so you build video assets in one place.
- 音声翻訳: Re-voice a finished script into another language without a new recording.
- 顔の形： Build a custom avatar from your own footage instead of using stock avatars.

機能比較
Both platforms let you create videos from text with AI avatars. The gap shows up in what happens after the render finishes. Here are nine areas that decide the winner, plus cost.
| 特徴 | コロサイ | シンセシス |
|---|---|---|
| 開始価格 | 月額19ドル | 月額20ドル |
| スクリプトからビデオへ | ✅ | ✅ |
| 文書をビデオに変換 | ✅ | ❌ |
| Multiple avatars per scene | ✅ | ❌ |
| Quizzes and branching | ✅ | ❌ |
| SCORM / LMS export | ✅ | ❌ |
| 音声クローン | ❌ | ✅ |
| AIが話す写真 | ❌ | ✅ |
| AI画像生成 | ❌ | ✅ |
| Screen recorder | ✅ | ❌ |
| 動画分析 | ✅ | ❌ |
| 最適な用途 | 職場研修 | Voice-led content |
1. スクリプトからビデオへ
コロシアン： You paste a script into an online rich text editor and the scenes build themselves. The document-to-video route is the bigger win. Existing PowerPoints, PDFs, and Word files become drafts in just a few clicks.
シンセシス： Text-to-video generation works cleanly for short pieces. There is no document import, so you rewrite source material by hand. That adds time to the video creation process on longer projects.
2. AI Avatars and AI Humans
コロシアン： The realistic AI avatars cover a range of accents and languages. The standout is staging: two or more speakers can share a scene. That makes role-play and simulated interviews possible.
シンセシス： AI Humans are presenter-style and front-facing. The AI avatar options look sharp on their own, but each scene holds one speaker. You get a spokesperson, not a conversation.
3. AI Voices and Voiceovers
コロシアン： The AI voices are solid and tuned for narration. You get engaging voiceovers quickly, though fine control over emotion and pacing is limited compared with a voice specialist.
シンセシス： This is the strongest column on the page. Voice cloning, tone tuning, and audio-only export mean you can skip hiring voice talent. If human voice talent is your current cost line, this is where the savings sit.
💡 プロのヒント: Render the same 60-second script in both tools and play it for a small test audience. Voice preference is subjective, and a five-person poll settles it faster than a spec sheet.
4. Backgrounds and Media Assets
コロシアン： Dynamic backgrounds pull from a media library of stock footage, animations, and music. Video templates cover onboarding, compliance, and product walkthroughs out of the box.
シンセシス： Generate AI Media creates original backdrops instead of pulling from a library. That helps when your brand look does not match generic stock. It also means more prompting before you get a usable frame.
5. Music and Audio Handling
コロシアン： Upload your own music track and set it under the narration. Ducking is automatic, so the avatar stays audible without manual level work.
シンセシス： Audio translations are the headline. Take a finished English voiceover and re-voice it in another language. For teams making the same video content for several markets, that saves a full recording cycle.
6. Scene Editing and Transitions
コロシアン： The video editor handles transitions between scenes without asking you to touch a timeline. Anyone with no video editing skills can reorder scenes and re-render.
シンセシス： Synthesys Lab is the experimental corner where new AI tools land first. It is fun to poke at, but the core editor is thinner than what other video generators ship.
7. Interactivity and Branching
コロシアン： Multiple-choice quizzes, clickable hotspots, and branching scenarios are native. Learners practice decisions in an automated and controlled way, which is the point of scenario training.
シンセシス： There is no interactivity layer. AI Talking Photos are the closest creative equivalent, animating a still headshot into a presenter. Useful for ads, not for assessment.
8. Screen Recording and Custom Faces
コロシアン： The built-in screen recorder captures software walkthroughs and drops them beside the avatar. That is how most product training gets made, so keeping it in one app matters.
シンセシス： Face Form turns your own footage into a custom presenter. You will not generate entire performances of a stranger, but you can put a real team member on screen repeatedly.
9. Analytics, Languages, and Export
コロシアン： Video analytics show views, completion, and quiz results. One-click translation covers roughly 70 to 80 languages. You can export videos or push SCORM packages into a learning management platform.
シンセシス： Multilingual support is broad on the audio side and reporting is basic. You get engagement counts, not learner-level completion data. Export is file-based, with API access on the Business plan.
10. 価格設定とコスト
Entry pricing is nearly identical. The gap opens at the middle tier.
| ティア | コロサイ | シンセシス |
|---|---|---|
| エントリ | Starter — $19/month | 個人向け — 月額20ドル |
| 中 | ビジネス向けプラン — 月額70ドル | クリエイター — 月額41ドル |
| トップ | エンタープライズ - カスタム | ビジネスプラン — 月額69ドル |
コロシアン： $19/month gets you in the door. The $70/month Business plan is the one that matters, because it lifts the minute cap. If you publish weekly training, the unlimited minutes pay for themselves.
シンセシス： $20/month for Personal, $41/month for Creator, $69/month for Business. Cheaper in the middle, and Enterprise pricing is not gated behind a sales call. Light users spend less here.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Employee onboarding | コロサイ | 職場学習向けに設計されています |
| Quizzes and branching | コロサイ | Native interactive elements |
| Best-in-class voiceovers | シンセシス | Voice cloning and tone control |
| Talking photos for ads | シンセシス | Animates a single headshot |
| Unlimited render minutes | コロサイ | Business plan lifts the cap |
| Lowest mid-tier cost | シンセシス | $41/month versus $70/month |
💰 あなたの予算
Entry plans sit a dollar apart, so budget alone will not decide this. Compare the middle tier instead, since that is where most teams end up.
🔌 あなたの技術スタック
If you already run an LMS, Colossyan slots in through SCORM export. Synthesys expects you to download files and upload them wherever they need to live.
📝 コンテンツの種類
Compliance modules, manager development programs, and coaching on performance conversations all favour Colossyan. Product ads and narrated explainers favour Synthesys.
🎓 あなたの経験レベル
Both ship an easy to use interface that a first-timer can handle. Colossyan’s intuitive interface holds up better once a project grows past ten scenes.
🆓 無料トライアルとデモ
Try both with one real script before you pay. Enterprise buyers should book a live demo, since custom pricing and 安全 review happen in that call.
🛟 サポートオプション
Both offer help through several channels and both hold to standard data protection rules. Colossyan’s docs go deeper on the training side.

私たちのレビューで取り上げられなかったこと
This comparison focused on small teams and L&D departments creating videos in-house. We did not test enterprise SSO, custom API workflows, or automation tools wired into an HR system. We also did not benchmark render speed at volume, and slow renders are a recurring Colossyan complaint. Our notes reflect the August 2026 versions of both platforms.

最適な用途: employee onboarding, interactive training, document-to-video conversion
These two products are aimed at different jobs. Colossyan is a learning platform that happens to render video. Synthesys is a voice platform that grew a video face.
If your work is marketing narration, product ads, or anything where audio carries the message, Synthesys is the sharper pick. The voice quality is worth the trade.
For everyone else, Colossyan is the safer default. It handles the full loop: script, quiz, export, and measure. That loop is what turns AI generated videos into training people actually finish.
