Voiceflow

PolyAI

PolyAI builds an Agentic Dialog Platform for enterprises, letting customer service, sales, and support teams deploy voice and chat agents that handle phone calls, appointments, and chat conversations without sounding robotic. The platform runs on Raven, PolyAI's proprietary dialog model trained on more than 1 billion enterprise conversations, and offers two build paths: Poly Agent Builder for non-technical teams and an Agent Development Kit (ADK) for developers who want deeper customization. Compliance and governance are built in by default, with SOC 2, HIPAA, GDPR, and PCI DSS support so agents can be deployed in regulated industries like healthcare, finance, and insurance. Named enterprise customers on the site include Howard Brown Health, Fogo de Chao, Audibel, PG&E, and Quicken, with case studies citing measurable outcomes such as incremental revenue and reduced seasonal hiring needs.

Landbot

Landbot is an AI agent and chatbot builder that lets marketing and sales teams create conversational experiences for lead generation, customer support, and sales automation using a drag-and-drop visual builder. It blends large language models like OpenAI and Gemini with rule-based flows, supports interactive elements like buttons, carousels, and forms, and deploys the same bot on a website widget and WhatsApp Business API. Built-in lead qualification routes and scores incoming leads before handing them to a sales rep or booking a meeting through a Calendly integration. Direct connections to HubSpot, Salesforce, and Airtable sync captured data into existing CRM pipelines, while Zapier and n8n extend the bot into thousands of other apps.

Chatbase

Chatbase is a platform for building and deploying AI agents that handle customer interactions without requiring code. It offers distinct agent types for customer support, sales, and product guidance, each configurable through plain-language procedures rather than scripting, and deployable across chat widgets, email, phone, WhatsApp, and Slack. The platform includes a built-in helpdesk for human handoff and escalation, prebuilt actions for common tasks like order lookups and refunds, and an analytics dashboard tracking resolution rates and sentiment. Enterprise-focused features include GDPR, SOC 2 Type II, and HIPAA compliance, support for multiple underlying AI models including Claude, GPT, and Gemini, and a guarantee that customer data isn't used for model training.

Enterprise Bot

Enterprise Bot is a conversational automation platform purpose-built for contact centers and large enterprises. It combines human-like AI conversations with automated workflows to help organizations resolve customer inquiries faster, reduce operational costs, and improve customer experience without adding headcount. The platform covers the entire customer journey, from high-volume support triage to end-to-end process execution, and can be embedded directly into existing call center ecosystems. At the core of Enterprise Bot is a unified AI engine that powers omnichannel engagement across voice, email, and chat. It offers AI Agent Assist with real-time call guidance, live transcription, automated call summaries, and smart wrap-ups, enabling human agents to focus on complex conversations. For more autonomous operations, its Agentic AI capabilities can complete entire workflows from start to finish, using tool calling and Model Context Protocols to take real actions and scale intelligently. Enterprises such as Callpoint, SWICA, and Kantonsspital Winterthur have deployed Enterprise Bot to improve customer service, create digital employees, and reduce agent workload. Customer-reported results include a 60% reduction in training effort for new agents, a 30% reduction in average handling time within one week, and an 8% reduction in customer data collection effort. The platform also provides native integrations with CRM, CCaaS, and backend systems, multilingual support, and enterprise-grade security with built-in audit trails.

Flowise

Flowise is an open-source visual builder for LLM applications and AI agents. Its drag-and-drop canvas composes chatflows and agentflows from components such as models, prompts, vector stores, tools, and memory, which can then be exposed through an API, an embeddable chat widget, or the built-in chat UI. Flowise orchestrates existing models rather than training them.
