Cons
- Credit-Based PricingUsage is credit-based (1 credit ~ 1000 characters), which can become costly for very high-volume or long-form content.
- No Free Tier or SubscriptionOnly one-time credit packs are offered; no free plan or monthly subscription option is available for ongoing needs.
- Two Models with Different CostsOnly two models (Flash and Pro) are available, and Pro costs double the credits (2 per 1000 chars), confusing for budgeting.
- Steep Learning Curve for TagsOptimal use requires learning 200+ audio tags, which may be overwhelming for casual users seeking simplicity.
- Minimum Charge for Short TextText under 1000 characters still consumes a full credit (or two for Pro), making short requests relatively expensive.
