This project contains a set of Node-RED nodes OpenSourced by VISEO to build Conversational Assistant.

  • It is architectured on top of (Microsoft Bot Framework)[] in order to connect to multiple channels.
  • New channels like WeChat, Google Home, Amazon Echo are also in the roadmap.


This project is also the v5 and full re-engineering of a SmartHome Assistant named SARAH (build in 2012).

VISEO is not a Software Editor but a Consulting Company (1300 people). Since 2016, everybody wants to build it's own bot. We believe that the key is to focus on User Exprience because technologies are not mature. That's why

  • we choose Node-RED platform to let developpers switch between pieces of NLP, Computer Vision, etc ...
  • we open-sourced our work to share the state of the art between our customers

If you are a company looking for experts to build a project of textual and/or vocal conversationnal assistant, feel free to contact us: contact [at] viseo [dot] io

Getting Help

All framework modules are installed with NPM. Custom private modules should be deployed in a node-red-contrib directory. (The project template already contains this directory)

Update nodesDir property of Node-RED configuration to use absolue path to the node-red-contrib folder as a module repository.
