Rasa
Agent platform
Platform for product and engineering teams to build, test, deploy and govern their own customer-facing AI agents across voice and text channels, with a free developer edition.
Rasa Voice provides infrastructure for real-time voice agents with turn-taking, interruptions, and rephrasing.
Retell AI
Agent platform
AI copilot on every page of the Retell dashboard: told in plain language what to change, it proposes edits to a voice or chat agent for approval, generates simulation tests from real calls, filters call and chat history to explain failures, and builds analytics charts.
Platform for building, deploying and monitoring AI voice agents that handle phone calls: call transfer to humans, appointment booking, IVR navigation, outbound call campaigns and post-call analysis.
Text counterpart of Retell's voice agents: businesses build AI chat agents with the same prompts, functions and knowledge bases, or convert a voice agent in one click, and deploy them in a website widget, over two-way SMS or through a chat API, billed per AI message.
No counterpart
Rasa sells these in a stack layer with no product recorded for Retell AI yet — nothing on the other side to compare them against.
Application
Self-hosted no-code workspace where non-developers visually build Rasa assistant flows, manage response content and test changes, exporting the assistant as code for the development team.
Platform
Rasa's dialogue engine (Conversational AI with Language Models): an LLM interprets what the user wants while versioned, deterministic flows decide what the agent does, with built-in repair when users change topic or backtrack.
Orchestrator at the core of the Rasa Platform that runs agents written as natural-language skills: it picks the active skill, hands off between skills, calls tools, keeps memory, and enforces guarantees such as required values or exact wording, on chat and voice alike.
