Rime AI vs Inworld AI: Features, Pricing and User Reviews 2026

Rime AI uses usage based pricing, so you only pay for the amount of speech you generate. The Starter plan begins at $0.03 per 1,000 characters, which is close to one minute of audio. New users get about 800 minutes free, worth around 800,000 characters, with no credit card required to start.

Pricing also depends on the voice model you pick. Mist v3 costs $0.03 per 1,000 characters and focuses on speed, while Coda costs $0.05 per 1,000 characters and focuses on natural sounding speech.

For larger organizations, the Enterprise plan moves to custom volume pricing based on scale. It includes unlimited concurrent voice generations, unlimited custom voice clones, dedicated support, and options to deploy on the cloud, on prem, or inside a private network.

Inworld AI offers six plans to fit different needs. The On-Demand plan is free and includes up to 70 minutes of text-to-speech, 100 custom voices, and access to the Realtime API and LLM Router.

Paid plans start with Creator at $25 a month, then Builder at $100, Developer at $300, and Growth at $1,500 a month, each lowering usage rates and raising custom voice and concurrency limits. Yearly billing brings the effective monthly price down on every paid plan.

Standard text-to-speech is billed per million characters, starting at $25 and dropping to $12.50 on Growth, while speech-to-text is billed hourly from $0.15 down to $0.10.

Enterprise plans offer custom pricing, on-premises deployment, and rates as low as $5 per million characters.
