 "summary": "Voice and model APIs for developers building consumer apps: realtime text-to-speech, speech-to-text, voice cloning and realtime conversation, pay as you go or on monthly plans.",
 "best_for": "developers and product teams building consumer apps with realtime voice, who want text-to-speech, speech-to-text and voice cloning through one API and can start pay as you go before committing to a plan",
 "skip_if": "you want a finished voiceover tool with an editor rather than an API; or you need guaranteed zero data retention on a mid-tier plan, which the docs tie to Enterprise",
 "honest_knock": "The bill is usage on top of the plan, counted on every input character including spaces, punctuation and tags. Credits roll over only while you stay subscribed, cancelling or downgrading forfeits the rest, and payments are non-refundable. The pricing page and the docs disagree on whether zero data retention is a Growth add-on or Enterprise only, and it does not cover requests sent to third-party model providers.",

  "notes": "(read 2026-10-15 on inworld.ai/pricing, the billing and concurrency pages of docs.inworld.ai and the terms at inworld.ai/terms; the page shows $ without naming a currency) Inworld sells voice and model APIs: text-to-speech, speech-to-text and realtime conversation. On-Demand is $0 and pay as you go: the billing docs say it includes up to 70 minutes of text-to-speech and 400 minutes of speech-to-text free, after which Realtime TTS-2 costs $25 per million input characters, TTS-2 Flash $15 and STT 1 $0.15 an hour of audio. The monthly plans lower those rates and raise the limits. Creator is $25 a month, with 500 custom voices and 4 professional clones, TTS-2 at $20 and Flash at $10 per million characters. Builder is $100 a month, with 3,000 voices and 10 clones, TTS-2 at $17.50 and Flash at $9. Developer is $300 a month, with 10,000 voices, 25 clones and priority email, TTS-2 at $15 and Flash at $8. Growth is $1,500 a month, with 30,000 voices and 40 clones, TTS-2 at $12.50 and Flash at $7, and lists zero data retention, HIPAA and a BAA as add-ons. Speech-to-text is $0.10 an hour on every paid plan. Enterprise has custom prices, limits and terms. Paid plans come with credits used across API and Playground products; subscription credits roll over for up to 3 months while an eligible paid plan stays active, and extra credits, bought by hand or by auto-reload, expire a year after purchase. The pricing page also has a yearly view with lower monthly figures, which we did not confirm. Text-to-speech is counted on input characters, including spaces, punctuation and tags that are not spoken.",

Inworld is narrower and built for developers, priced as pay as you go from $0 or plans from $25 a month with per-character rates that fall as you move up. For creating voice content, look at ElevenLabs; for putting realtime voice into your own app at volume, compare Inworld's per-character rates."
