Welcome.
This is for two kinds of people: business owners who want their operations running without them, and anyone who wants to actually learn n8n. In the Classroom you'll find working n8n workflows — real ones, built to be used, not demos. Use this feed for questions. When you ask, be specific: what you were building, what broke, and the actual error. Say hi below: what do you want to automate first, and where are you stuck?

Uber switched off $100M of ads. Nothing happened.
Uber switched off $100 million a year of ads, and installs didn't change. In 2017, Uber's ads kept showing up on a site Uber had blacklisted. Kevin Frisch, then Uber's head of performance marketing for the US and Canada, cut every ad network that put them there: about 10% of the rider ad budget. New riders didn't drop. In the data, people were opening Uber two seconds after seeing an ad. That's impossible. Fake apps, like battery savers, sat on people's phones and fired an invisible ad click when someone typed Uber into the app store. The person installed Uber on their own, and the ad network claimed the install and billed Uber. So Uber switched off two thirds of its rider ads: about $100 million of roughly $150 million a year. Installs didn't change. The paid installs just showed up as free ones. Uber cut another $20 million, leaving about $30 million, and took the ad companies to court. A test any advertiser can run: switch one channel off and watch whether sales move. Sources: - Kevin Frisch on Marketing Today with Alan Hart, episode 194 (February 2020) - Uber Technologies v. Fetch Media, US District Court, Northern District of California, case 4:17-cv-05393, filed September 18, 2017 - Phunware's 2020 annual report (10-K): it settled Uber's lawsuit and agreed to pay Uber $4.5 million in three installments #uber #marketing #adfraud #advertising #business THE VIDEO https://youtube.com/shorts/WHqWhBbymxU

She paid off $12,078 of debt with one ChatGPT task a day
She paid off $12,078 of credit card debt in 30 days by asking ChatGPT for one task a day. Her exact messages, the tasks that paid the most, and how to run it yourself. Jennifer Allan, a realtor in Delaware, owed $23,000 on credit cards. Every day for 30 days she asked ChatGPT for one task to make or save money, and paid off $12,078.93. (Reported by Good Morning America, Newsweek and People.) The messages, in order: 1. Her first message: "I'm in credit card debt. I literally have no idea how much, and I don't even know where to start." 2. Then give it each card's balance, interest rate and minimum payment: "Build my debt tracker as a table, and tell me which card to pay first." Pay the minimum on the others and every extra dollar on the highest rate. 3. Every day, in the same chat: "Give me one task for today to make or save money to pay down this debt. Something I can finish in an hour." The tasks that paid her the most: - Check every account you've ever had: an old-job brokerage account held $10,200, and Venmo held $100.80. - Unclaimed money: $700 for her business. In the US, MissingMoney.com searches most states at once. Elsewhere, ask ChatGPT for your government's official unclaimed money search. - A month of meals from only what was in her pantry: almost $600 saved. - Coins in old purses and the couch: over $100. Never type card numbers or passwords into the chat. It only needs balances and rates. Check its maths: it's for ideas, not financial advice. The card numbers in the video are made up for the demo. #chatgpt #debt #creditcard #money #budget THE VIDEO https://youtube.com/shorts/WN3rCPkWlpU

Get hired with ChatGPT, from the job ad to a bigger offer
Get hired with ChatGPT, from the job ad to a bigger offer. Every step, run on a real Dropbox job ad. A tech project manager was offered $108,000. She asked ChatGPT for a negotiation script and got $22,000 more in her first year: a $120,000 salary, a $10,000 signing bonus and a pay review at six months. (Reported by MoneyLion, on AOL, May 2026.) The prompts, in order: 1. Paste the whole job ad and your CV, then: "What does the ad ask for that my CV doesn't show? Short list, most important first." 2. "Rewrite my CV bullets in the ad's own words. Only use what's true. If a bullet needs a number, ask me for it instead of making one up." Check every line before you send it. 3. "Now be the hiring manager for this job and interview me. Ask one question at a time and wait for my answer. After each answer, score it out of 10, say what was missing, and show a stronger version using only my real experience." In the ChatGPT app, tap the voice icon to answer out loud. 4. "Which three questions will I struggle with most, because of the gaps in my CV? Give me an honest answer to each." 5. When the offer comes: "They offered me [offer]. The ad says [range]. Write what I say back to ask for more. Base it on what I've delivered, not what I need. Give me one number to ask for, and two things to ask for if they say the salary is fixed." Why the ad's own words: Greenhouse, which runs Dropbox's hiring, lets recruiters filter applications by keywords it suggests from the job post, and a keyword has to match exactly. The CV and the offer in the video are made up for the demo. The job ad is a real Dropbox listing. #chatgpt #jobsearch #resume #interview #salary THE VIDEO https://youtube.com/shorts/1FZ2EoFFEmg

How AI cut a $195,000 hospital bill to $33,000
How AI cut a $195,000 hospital bill to $33,000, and how to run the same check on any bill. A man says a $20-a-month AI subscription helped his family cut a $195,000 bill for four hours of intensive care to $33,000. (His own account, reported by Tom's Hardware and Yahoo Tech in October 2025.) 1. Ask for an itemised bill with every billing code. One line on the first bill just said "Cardiology, $70,000". 2. Paste it into Claude or ChatGPT and ask it to check every code: charges listed twice, parts billed on top of their package, the wrong visit type. In his bill, parts billed on top of their package came to about $100,000. 3. Ask it to write the dispute letter, quoting each code. Check every line it flags yourself before you send it. Try it on any bill you can get itemised: phone plans, car repairs, bank fees. #ai #chatgpt #claude #money #medicalbills THE VIDEO https://youtube.com/shorts/q2SMuwveoNA
