## Ways to pay less

- **2 months free on yearly billing** (Annual discount): Inworld's pricing page has a Yearly toggle labeled as giving 2 months free compared with monthly billing. Source: https://inworld.ai/pricing

## Key features

- **Realtime TTS-2 and TTS-2 Flash:** Two text-to-speech models priced per million characters, with steering on TTS-2, speaking rate and temperature controls, and 200+ languages.
- **Voice cloning and design:** Instant cloning and voice design are on every plan; professional voice clones are capped by tier, from 2 to 40 and 100+ on Enterprise.
- **Speech to text and speech to speech:** Real-time STT from $0.15 an hour on On-Demand and low-latency speech-to-speech conversations on the same credits.
- **LLM inference:** Hosted open and third-party models are billed per token from the same credit balance, from $0.07 per 1M input tokens.
- **Credits that roll over:** Unused subscription credits carry over for up to 3 months while a paid plan of equal or higher value stays active.

## Good for

- Developers building real-time voice agents or companions
- Game and app teams that need many custom voices
- Small projects that want a predictable monthly credit

## Worth knowing

- Overage is billed at the plan's own rates, and extra credits expire one year after purchase.
- The 70 free minutes on On-Demand are not described as monthly, so treat them as a trial amount.
- Zero data retention starts at Developer, and HIPAA and BAA are Growth add-ons.
- The page showed monthly prices; a Yearly toggle advertises 2 months free, so the annual amounts were not read.

## Keep it, or make your own?

**Keep it.** To replace Inworld AI you would be making a voice model, which you can rent by the minute but not make. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 26 of the 43 other AI voice generators grade higher. It costs $300 a year.

- You could not: A voice model, which you can rent by the minute but not make.
- You could not: A voice model trained on your recordings.
- You could not: Speech turned into text you can trust.
- You could not: An API that other software can build on.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
