In their own words
SOVA
SOVA is a free, open-source ecosystem for building conversational AI, including virtual assistants, chatbots, speech tools, and neural-network software. SOVA IDE provides tools to develop, test, and release assistants, with a knowledge base, dialog processor, and team development features. Its dialog language supports rules, variables, external database queries, and modular dialogue structures. ChatKit is a React component set for chat widgets, with file sending, media, message editing, search, and channel selection. SOVA ASR converts recorded or live speech to text, while SOVA TTS generates audio from text. The maker says these speech tools run locally and are licensed under Apache 2.0 for academic and commercial development. SOVA lists 28,853 hours of labeled Russian and English audio under CC-BY 4.0. Products can run offline, in Azure or AWS, or locally using Docker. SOVA Mobile for iOS and Android supports text and voice messaging, multiple assistants, and conversation history. The maker also directs enterprise inquiries to Sales.
Voiceflow
Voiceflow is a platform for building, testing, deploying, and monitoring chat and voice agents across channels and languages. Its builder combines agentic playbooks, deterministic workflows, shared instructions, and guardrails. Teams can review transcripts and call recordings, run evaluations and tests, and track analytics. Agents can reach users through a native chat widget, mobile apps, phone calls, SMS, or custom interfaces built with the Conversations API. Native integrations include Zendesk, Salesforce, HubSpot, Shopify, Airtable, Google Sheets, Gmail, and Twilio. Agents can also connect to external REST APIs, custom Functions, and MCP servers. Teams can choose from major LLM providers or bring their own model. Voiceflow says customer data is not used to train AI or machine-learning models and integrated model providers are configured for zero data retention. Its security information describes encryption at rest with customer-managed keys and encryption in transit using TLS and mTLS. The company was founded in 2019. Agencies and partners have a free-trial plan with usage-based billing; business pricing is available on request. Support includes implementation that can be self-serve or fully managed.
