In this video, I show you how I stopped wasting hours manually testing and debugging my n8n AI agents. I use a simple Instagram DM chatbot demo (webhook → AI agent → send reply) and then I let AI assistants do the boring part: they actually open Instagram, send messages, wait for replies, and keep the conversation going so I can see where my agent breaks. The goal is simple—test faster, catch bad behaviors quicker, and iterate without you sitting there typing prompts all day. I cover two tools: the Claude browser extension and Perplexity’s Comet browser assistant. With Claude, I add the Instagram tab into the Claude “group tab,” pick a model (I mention Opus 4.5 is the best but it burns credits fast), and then I prompt Claude to roleplay a persona and chat with my agent. Then I do the same with Comet, but I add stricter instructions like “one message at a time” and “stop after booking an appointment,” and Comet actually follows that flow better and gives a clean summary at the end. The big takeaway: create personas, run automated conversations, collect the transcripts, and use that feedback to improve your agent way faster—and scale your testing without scaling your time.
