Paid plans start at $25/mo. There's also a free plan.
Inworld AI has a $0 On-Demand tier for evaluation and prototyping, plus paid plans starting at $25 per month for Creator. That plan includes $25 in monthly credits, but the pricing details here do not give per-unit rates for usage. Higher tiers add credits, custom voices and concurrency; Developer costs $300 monthly, while Growth is $1,500. Budget against your expected speech and inference use before committing, and confirm add-on costs separately.

02What the plan grid doesn't tell you
Unpriced compliance add-ons
HIPAA/BAA and zero data retention are Growth add-ons; the published pricing details do not list their prices.
Additional credits
Additional credits and auto-reload use current-tier rates, but those rates are not listed on the vendor's site.
Usage overages
Overages are charged at your plan's rate. Exact per-unit rates are not published here, so forecast spend from expected usage.
Custom Enterprise pricing
Enterprise has custom terms and limits but no fixed listed price. Request a quote before comparing it with a paid tier.
03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Evaluation and prototyping | On-Demand | No monthly price is listed; includes up to 70 TTS minutes, 100 custom voices and five concurrent requests. |
| Growing projects and small teams | Builder | $100/month includes $100 in credits, 3,000 custom voices, 50 concurrent requests and workspace sharing. |
| Production applications | Developer | $300/month includes $300 in credits, 150 concurrent requests and priority email support. |
04Is Inworld AI worth the money?
Inworld AI is worth evaluating if speech is central to your application: the plans spell out voice and concurrency limits, and On-Demand lets teams start without a monthly price. But the listed monthly credits do not tell you what your actual usage will cost, and add-on prices are missing. We would price a realistic workload and confirm overage rates before production. Without comparable category rates in the pricing material, we can't call it cheap.
