Best for real-time voice for agents and companions
Inworld AI sells text to speech, speech to text and an LLM API, with monthly credit plans from $25. The On-Demand plan includes up to 70 minutes of speech, and 100 custom voices come with it. The 70 minutes are not described as monthly, and the page shows monthly prices only.
Who Inworld AI is for
- Fits if you are building a real-time voice agent or companion
- Works for game or app teams that need many custom voices
Who Inworld AI is not for
- Not for you if you want to paste a script and download, because this is an API product
- Watch out: the 70 free minutes aren't described as monthly, so don't count on them renewing
- Watch out: zero data retention starts at Developer ($300), and HIPAA and BAA are Growth add-ons
- Pricey if you go over the credit: overage bills at the plan's own rates, and extra credits expire after a year

Keep Inworld AI, 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.
What you could not
- A voice model, which you can rent by the minute but not make.
- A voice model trained on your recordings.
- Speech turned into text you can trust.
- An API that other software can build on.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Inworld AI’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Inworld AI?
Inworld AI sells a developer platform for real-time voice: text to speech, speech to text, speech to speech and hosted LLM inference. Plans are monthly subscriptions that return their price as usage credits, with lower per-character rates on higher tiers. It targets companions, tutors, games and voice agents.
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.
