Chat Data vs Voiceflow

Chat Data is an AI agent platform for customer-support chatbots and live chat on websites. Businesses can build agents from documents and site content, then deploy them through a chat widget, API, or channels such as WhatsApp, Slack, Messenger, Instagram, Telegram, Discord, and LINE. Agents can be trained from uploads, Google Drive, Notion, YouTube, and video or audio inputs. The platform includes a visual flow builder, bot generation, knowledge-base answers, and live handoff to human agents. It also supports real-time voice mode and customized ElevenLabs voices. Chat Data lists 834 built-in MCP apps with more than 10,000 tools, alongside third-party integrations including Zendesk, Shopify, and WordPress. Its REST API uses bearer-token authentication and is limited to 600 requests per minute. The service offers a free plan and paid plans from $15.83/mo (annual). Free includes 100 message credits per month; conversation history is retained for 0.5 years on Free and longer on paid tiers.

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.
