What is Dasha?
Dasha is a conversational voice AI platform that enables developers to build ultra-realistic, human-like voice AI agents for telephony, WebRTC, and text channels. It is designed for developers shipping production voice AI at scale, offering sub-second latency (1070ms, ranked #1 on voicebenchmark.ai) and the ability to handle 10,000+ concurrent calls. The platform automates voice processes such as customer feedback surveys, sales and up-sells, call center operations, claims processing, appointment scheduling, and HR inquiry handling.
Key features include DashaScript (a TypeScript-based domain-specific language for conversational flows), REST API for simple integration, SDK support for JavaScript/Node.js, support for 30+ languages with mid-call language switching, and the flexibility to use any LLM (GPT, Claude, Gemini, etc.) without vendor lock-in. The platform offers voice interruption enhancements, VoIP integration, and one-second billing increments. Over 495 million calls have been powered by Dasha to date.
Dasha is primarily for developers and businesses building production voice AI applications, including call centers, sales teams, customer support operations, healthcare providers, telecom companies, car dealerships, and HR departments. It serves both startups through its free developer tier and enterprises needing high-concurrency production workloads with 99.99% uptime SLA.

How does Dasha ensure natural-sounding conversations?
Dasha leverages advanced large language models (LLMs) to create ultra-realistic voice AI agents with sub-second 1070ms latency, ensuring lifelike and context-aware interactions that are indistinguishable from human conversations with voice interruption support.
Is Dasha scalable for high-volume customer support?
Absolutely. Dasha is designed to handle 10,000+ concurrent calls without compromising quality, making it ideal for high-volume customer support operations. Over 495 million calls have been powered by Dasha to date.
What languages does Dasha support?
Dasha supports over 30 languages and even allows for mid-call language switching, so if a customer switches to Spanish mid-sentence, the AI adapts instantly without restart or awkwardness.
Can I customize the AI agents to fit my business needs?
Yes, Dasha offers extensive customization options through DashaScript, a TypeScript-based domain-specific language designed for conversations, allowing you to tailor AI agents to meet specific business requirements and complex multi-turn workflows.

Can I switch LLM providers after building with Dasha?

How is Dasha billed for calls?
Dasha uses one-second billing increments with no minimum call duration, so a 5-second call is charged as exactly 5 seconds. You're only charged for successful connections, with no charge for call attempts that don't connect.
What is DashaScript and when should I use it?
DashaScript is a TypeScript-based domain-specific language designed for creating human-like conversational experiences. Use SDK + DashaScript when you need full control over conversation flow, complex multi-turn workflows, and predictable AI behavior, versus REST API which is for simpler integrations where you want to ship in days.
