# NexiAgent and NexiChat: two brands, one company

NexiAgent and NexiChat are two brands of the same company, ISEGTEC, LDA, based in Porto, Portugal. NexiChat is the AI assistant in European Portuguese, with the Nexi models; NexiAgent uses that technology to put assistants on other businesses' phone lines and website chats.

## NexiChat

An AI assistant in European Portuguese, with its own models: Nexi Air, Nexi Prime and Nexi Nova. It lives at [nexichat.ai](https://nexichat.ai); the documentation is at docs.nexichat.ai and the developer console at developer.nexichat.ai.

## NexiAgent
