In their own words
Radioso
Radioso provides open-source AI agents for support tickets, help-center answers and lead qualification. Agents can use policies and help-center content for routine work such as returns and escalations, call tools, trigger webhooks, run multi-step routines and hand difficult conversations to people with context. Answers can cite uploaded documents and knowledge shared across channels. Assistants are reachable through Slack, an embedded website widget, public chat, REST API, SDK and MCP server; in Slack, users can mention @Radioso or send a direct message. Radioso runs in its cloud or on customer-operated infrastructure using the customer’s model keys. The Open source plan costs nothing, includes all product features and supports self-hosting. Radioso says ingested content, conversations and prompts are not used to train its own models. Radioso Cloud uses Google Cloud Platform in an EU region and PostHog EU Cloud for analytics, while configured AI providers may process prompts and retrieved context primarily in the United States. Security measures listed include encryption in transit, access controls, audit logging and least-privilege practices.
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.
