NLX
Build conversational AI for chat, voice, phone, and synchronized Voice+ experiences with a no-code workflow.
NLX is now part of Amazon Connect.
About NLX
NLX is a no-code platform for conversational AI applications across chat, voice, phone, and synchronized Voice+ experiences. Teams can build agents, connect managed or custom APIs, apply guardrails, and use either built-in AI or their own LLM keys. Developers can embed those applications through REST, WebSocket, Streamable HTTP, OpenAI-compatible, and MCP interfaces. The platform supports more than 65 languages and allows teams to change model providers. Growth includes $20 in free credit, followed by billing at $0.20 per conversation. It provides one workspace, five builder seats, ten read-only seats, ten applications, ten concurrent NLX Voice sessions, and 14-day data retention. Enterprise removes the published limits on workspaces, seats, and applications, with custom terms for pricing, retention, concurrency, support, and security.
Best for
Best use cases
Validate a customer-service agent with the Growth free credit before paying per conversation.
Deploy chat, phone, voice, or Voice+ applications and connect them to tools and APIs.
Negotiate enterprise capacity, retention, identity controls, compliance documentation, and service levels.
Compare before choosing
Growth trades a low-commitment start for published workspace, seat, application, concurrency, and retention limits.
Bring-your-own LLM support can reduce model lock-in, while managed integrations can reduce connection work.
Enterprise is the relevant comparison point when governance and support requirements exceed Growth limits.
Features
Customer-service voice agents
Build voice and phone agents that manage customer-service conversations, call connected business tools, and use Voice+ to coordinate spoken responses with on-screen actions. This supports hands-free service flows while keeping the digital interface synchronized with the conversation.
Multichannel conversational apps
Create conversational applications for chat, voice, phone, web, and mobile channels, then connect each experience to managed integrations or custom business APIs. Teams can reuse the same platform while choosing the delivery channel and integration interface that fits each product.
Enterprise agent orchestration
Coordinate conversational applications across larger teams with guardrails, role-based access, SSO, custom voice capacity, negotiated data retention, training, and enterprise support options. This use case fits deployments that have outgrown the published Growth limits and need formal governance terms.
Pros
- Growth starts with $20 in free credit and has no contract requirement, lowering the cost of a first production test.
- No-code building, managed integrations, and multiple API protocols support both business builders and developers.
- Support for chat, voice, phone, Voice+, 65+ languages, and bring-your-own LLM keys reduces channel and model lock-in.
Cons
- Growth costs $0.20 per conversation after the free credit, so high-volume deployments need usage forecasting.
- Growth is limited to one workspace, five builder seats, ten applications, and ten concurrent NLX Voice sessions.
- Growth retains data for 14 days; longer retention, SSO, role-based access, and formal compliance reports require Enterprise terms.
