Why it stands out
Cartesia should be framed as a voice platform with both model and agent economics. The pricing details are part of the product story.

Tool profile
Voice AI platform for ultra-low-latency speech, voice cloning, agent creation, and real-time voice experiences with both monthly plans and usage-based call economics.
Voice AI
Cartesia belongs in the database because it is not just another speech API. The official product and pricing surfaces position it around low-latency text-to-speech, voice cloning, voice agents, text-to-agent workflows, evaluations, and operational features for real-time voice products. That makes it a serious builder tool for companies shipping voice experiences, not just a model endpoint to benchmark once and forget.
It also deserves inclusion because the pricing is detailed and commercially legible. The official pricing page currently shows Free at $0/month, Pro at $5/month, Startup at $39/month, Scale at $239/month, and Enterprise as contact sales, while also publishing credits, prepaid agent balances, concurrency, and usage rates such as per-minute call charges and text-to-agent creation costs. That level of specificity is exactly what a premium tools database should capture.
