Automatic AI reply when mentioned in a Liveblocks comment

Automatic AI reply when mentioned in a Liveblocks comment

This example uses Liveblocks Comments, collaborative commenting components for React. When an AI assistant is mentioned in a thread (e.g. "@AI Assistant"), it will automatically leave a response.

Using webhooks, this workflow is triggered when a comment is created in a thread. If the agent's ID ("__AI_AGENT") was mentioned, an AI agent is given the entire thread context, and asked to create a response. This response is then added, and users will see it appear in their apps in real time.

Set up This workflow requires a Comments app installed and webhooks set up in the Liveblocks dashboard. You can try it with a demo application:

Download the Next.js comments example, and run it with a secret key. Find database.ts inside the example and uncomment the AI assistant user. Insert the secret key from the project into n8n nodes: "Get a comment", "Get a thread", "Create a comment". Go to the Liveblocks dashboard, open your project and go to "Webhooks". Create a new webhook in your project using a placeholder URL, and selecting "commentCreated" events. Copy your webhook secret from this page and paste it into the "Liveblocks Trigger" node. Expose the webhook URL from the trigger, for example with localtunnel or ngrok. Copy the production URL from the "Liveblocks Trigger" and replace localhost:5678 with the new URL. Your workflow is now set up! Tag @AI Assistant in the application to trigger it.

Localtunnel The easiest way to expose your webhook URL: npx localtunnel --port 5678 --subdomain your-name-here This creates a URL like: https://honest-months-fix.loca.lt The URL you need for the dashboard looks like this: https://honest-months-fix.loca.lt/webhook/9cc66974-aaaf-4720-b557-1267105ca78b/webhook `
