Decagon
Agent platform
Decagon's authoring layer for the rules an AI support agent follows, so non-engineering teams can build, iterate on and scale agents.
An AI partner built into Decagon that helps teams build and improve support agents — distilling best practices from hundreds of Decagon deployments into guidance for the builder, and auto-tuning the agent via "Duet Autopilot," which improves it with every conversation it handles.
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.
