# Dasha AI - Comprehensive Product Information > Dasha AI is a platform for building ultra-realistic voice and text AI agents. It enables developers and businesses to deploy conversational AI agents that handle real-time phone calls, WebRTC sessions, and text-based interactions with human-like fluency and sub-second response times. ## Company Dasha.AI Inc. was founded in 2019 by Vlad Chernyshov. The company is headquartered at 575 Market St, San Francisco, CA 94105, USA. Dasha focuses on enabling developers to create production-grade voice AI agents that can replace or augment human agents in customer-facing conversations. ## Core Product: Dasha AI Platform ### Voice AI Agents Dasha's core offering is ultra-realistic voice AI agents. These agents conduct phone conversations that are nearly indistinguishable from human agents. Key voice capabilities include: - **Ultra-realistic speech synthesis**: Proprietary TTS engine producing natural-sounding speech with appropriate prosody, emotion, and pacing. - **Real-time conversation**: Sub-second latency for natural turn-taking, supporting interruptions and overlapping speech. - **Telephony integration**: Native support for PSTN (public switched telephone network) and SIP (Session Initiation Protocol) for both inbound and outbound calls. - **WebRTC support**: Browser-based voice interactions for web applications without requiring phone infrastructure. - **Multi-language support**: English and Russian language support for both speech recognition and synthesis. ### DashaScript DSL DashaScript is Dasha's domain-specific language for defining conversation flows. It provides a declarative way to specify: - Dialogue states and transitions - Intent recognition and entity extraction - Context management across conversation turns - Error handling and fallback strategies - Integration points with external APIs and databases - Conditional logic based on conversation context ### REST API The Dasha REST API enables programmatic control of AI agents: - Start and manage conversation sessions - Configure agent behavior at runtime - Retrieve conversation transcripts and analytics - Integrate with CRM systems, helpdesks, and business tools - Manage agent deployments and versions - Access call recordings and real-time events ### Analytics and Monitoring - Real-time conversation monitoring - Call recording and transcript generation - Performance metrics (latency, completion rates, customer satisfaction) - Conversation flow analytics for optimization ## Technical Architecture Dasha operates as a cloud-hosted platform: - **Agent OS**: The runtime environment that executes DashaScript applications, managing conversation state, speech processing, and external integrations. - **Agent-to-Agent Communication**: Supports scenarios where multiple AI agents collaborate on complex tasks, delegating subtasks and orchestrating workflows. - **Voice AI Backend**: The infrastructure layer handling speech recognition, synthesis, telephony, and WebRTC connections. ## Use Cases Dasha AI agents are deployed across multiple industries and functions: ### Customer Service - Automated inbound call handling for support inquiries - Outbound follow-up calls for issue resolution - 24/7 availability without staffing constraints ### Sales and Lead Qualification - Outbound prospecting calls at scale - Lead qualification and appointment scheduling - Follow-up calls for abandoned carts or incomplete applications ### Healthcare - Appointment scheduling and reminders - Patient intake and triage - Prescription refill requests ### Financial Services - Account inquiries and balance checks - Payment processing and reminders - Fraud alert verification calls ### Real Estate - Property inquiry handling - Appointment scheduling for viewings - Follow-up with leads from listings ### Collections - Payment reminder calls - Payment arrangement negotiations - Account status updates ## Pricing Dasha offers tiered pricing to accommodate different usage levels: ### Free Tier - Available for developers to build and test applications - Access to the full platform capabilities for development - Suitable for prototyping and proof-of-concept work ### Growth Plan - Production-grade usage with higher concurrency limits - Priority support and dedicated account management - Higher API rate limits and call volumes - Custom voice profiles and advanced configuration options - SLA guarantees for uptime and latency All plans are billed in USD. The platform offers pay-as-you-go pricing for call minutes and API usage beyond plan limits. ## Competitive Positioning Dasha differentiates from alternatives in several categories: ### vs. API Platforms (Twilio, Vonage) Dasha provides a complete voice AI solution rather than requiring developers to assemble multiple APIs (STT, TTS, telephony, NLU) into a working system. This reduces development time and ensures optimized end-to-end latency. ### vs. Open Source Frameworks While open-source voice AI tools offer flexibility, they require significant infrastructure expertise to deploy and maintain at production scale. Dasha handles infrastructure, scaling, and optimization, letting developers focus on conversation design. ### vs. DIY Solutions Building a custom voice AI stack requires expertise in speech recognition, synthesis, telephony, NLU, and real-time systems. Dasha provides all these capabilities in a single platform, eliminating the need to integrate and maintain multiple components. ## Voice Benchmark Performance Dasha participates in independent voice AI benchmarks at voicebenchmark.ai, where performance is measured on latency, voice quality, and conversation handling. Dasha consistently ranks among the top performers in end-to-end latency measurements. ## Integration Options - **CRM Integration**: Salesforce, HubSpot, and custom CRM systems via REST API - **Helpdesk Integration**: Zendesk, Freshdesk, and others via webhooks - **Telephony Providers**: Compatible with major SIP trunking providers - **Cloud Platforms**: Deployable alongside AWS, GCP, and Azure workloads - **Custom Webhooks**: Real-time event notifications for conversation events ## Documentation and Resources - [Developer Documentation](https://docs.dasha.ai) - [Blog](https://dasha.ai/blog) - Technical articles, tutorials, and product updates - [GitHub Samples](https://github.com/dasha-samples) - Example applications and starter projects - Community: Developer community and support channels ## Contact Information - [Website](https://dasha.ai) - Support Email: support@dasha.ai - [LinkedIn](https://www.linkedin.com/company/dashaai/) - [Twitter](https://twitter.com/DashaAI_/) - [GitHub](https://github.com/dasha-samples) - Address: Dasha.AI Inc., 575 Market St, San Francisco, CA 94105, USA
