After registering, you receive 180 K-coins, equivalent to approximately three minutes of video generation. The workflow is not complicated: choose a digital human, enter the script, select a voice, and generate.
The resulting talking-avatar videos are not exceptionally realistic, but they are good enough for a first draft of a marketing video.
What takes more time to understand is how K-coins are deducted.
Different tiers of digital humans consume different amounts. Selected digital humans cost approximately one K-coin per second, while premium digital humans cost around two K-coins per second. Text-to-speech consumes 18 K-coins per 60 seconds, and each AI-model generation costs around 20–30 K-coins.
This explains why different sources provide widely varying estimates of how much video the Pro plan can generate. The actual number of minutes depends on the digital human and features you choose, so it cannot be determined from the plan’s total K-coin allowance alone.
Free users can enter a maximum of 200 characters per generation, equivalent to roughly one minute of video. Longer content requires a membership upgrade.
There is also a noticeable difference between monthly and annual pricing. Premium costs approximately $21 when billed monthly, but around $11 per month when billed annually. If you know you will use the service long term, annual billing offers better value.
Digital-human cloning is priced separately. The ¥3,499 package includes one avatar and voice clone, plus one month of Pro. If you do not need a digital version of yourself, the platform’s existing avatars should be sufficient.
Pros
- Lower annual price: Premium costs approximately $11 per month with annual billing, making it cheaper than HeyGen at $24 per month and Synthesia at $22 per month.
- Enough free usage for testing: The 180 K-coins let you experience the complete digital-human video workflow.
- Comprehensive feature set: Digital humans, voiceovers, AI models, video translation, and URL-to-video generation are available on one platform.
- Strong multilingual support: Supports more than 140 languages and a large selection of voices, making it suitable for international marketing.
- Many e-commerce tools: Features such as AI models and product-link-to-video generation are closely aligned with cross-border commerce.
Cons
- Complicated K-coin rules: Consumption varies by feature and digital-human tier, making costs difficult to estimate in advance.
- K-coins expire: Unused allowances are not retained indefinitely.
- Many free-plan restrictions: Each input is limited to 200 characters, videos include a watermark, and content is retained for only 60 days.
- Monthly billing is relatively expensive: Premium costs $21 per month, significantly more than its effective monthly price under annual billing.
Best for / Not ideal for
Best for
- Cross-border e-commerce businesses and global brands: Suitable for producing multilingual marketing videos at scale for platforms such as TikTok and Meta.
- Content creators who do not want to appear on camera: Digital humans can handle on-screen presentations.
- Marketing teams: Useful for continuously producing different video variants for testing.
- Small teams with limited budgets: Premium’s annual price is relatively accessible.
Not ideal for
- Users who prioritize highly realistic digital humans: The results are geared more toward practicality and still fall short of leading digital-human platforms.
- People who only create basic digital-human videos: If you do not need multilingual features, AI models, or e-commerce tools, some of the platform may offer little practical value.
- People who dislike credit-based pricing: Combining K-coins with different avatar tiers makes actual consumption less intuitive than per-minute billing.
