Questions, answered
How is Rime priced?
Rime is priced by usage, and you only pay for what you use. Starter begins at $0.03 per 1,000 characters (about a minute of audio): $0.03 for Mist and $0.05 for Coda. Enterprise plans move to volume pricing tailored to your scale.
Can I get volume discounts for Rime?
Yes. The Enterprise plan is built around volume pricing for organizations running at scale, with SLAs and dedicated support included. Talk to us and we'll shape a plan around your usage.
Does Rime have a free plan?
Every new account starts with 3,000 free minutes on the Starter plan, enough to build, test, and hear Rime in your own product before you spend a dollar.
Does Rime have multiple voices to choose from?
Choose from 600+ voices, then shape accent, pace, and tone until it fits your brand and your industry, with real fluency across 50+ languages.
Does Rime have an open API?
Yes. Drop Rime in through a simple API, or self-host when compliance demands it. Most teams are up and running the same afternoon.
