What Rasa does
Rasa is a pro-code conversational AI platform for dialogue flows, language understanding, enterprise search, actions, testing, and self-managed deployment.
Rasa emphasizes controlled conversational workflows. Rasa Pro supplies developer infrastructure for CALM, connectors, actions, tests, PII handling, models, telemetry, and Kubernetes; Studio adds collaborative visual editing and conversation review.
Developer Edition is free for one bot per company with up to 1,000 external or 100 internal monthly conversations. Enterprise is quoted. Studio, hosting, support, voice, model APIs, vector search, and implementation can affect total cost.
Flows reduce but do not remove hallucination, routing, injection, or integration risks. Trackers may contain personal data and actions can change systems. Minimize retention, protect secrets, sandbox tools, require confirmation for consequential actions, test interruptions, and preserve human handoff.
How Rasa works
Teams define flows, slots, responses, policies, retrieval, and custom actions. Rasa CALM uses language models to understand user language and context while dialogue management follows configured business logic and calls approved actions. Trackers preserve events for tests and analysis. Designers and engineers review simulations, transcripts, side effects, and fallback behavior.
