Create a secure personal AI assistant with OpenAI and Signal Messenger

 Overview

This workflow streamlines the process of setting up a chat-bot using the Signal Messager API.

What this is for

Chat-bot applications have become very popular on Whatsapp and Telegram. However, security conscious people may be hesitant to connect their AI agents to these applications. Compared to Whatsapp and Telegram, the Signal messaging app is more secure and end-to-end encrypted by default. In part because of this, it is more difficult to create a chat-bot application in this app. However, this is still possible to do if you host your own Signal API endpoint.

This workflow requires the installation of a community-node package. Some additional setup for the locally hosted Signal API endpoint is also necessary. As such, it will only work with self-hosted instances of n8n.

You may use any AI model you wish for this chat-bot, and connect different tools and APIs depending on your use-case.

How to setup Step 1: Setup Rest API Before implementing this workflow, you must setup a local Signal Client Rest API.

- This can be done using a docker container based on this project: [bbernhard/signal-cli-rest-api](https://github.com/bbernhard/signal-cli-rest-api).
