Example use cases from our research interviews
"Trained my AI on 15 years of dev emails. Now I chat with it on Telegram while I'm cooking dinner. Sold 3 hours of consulting this week while I was literally asleep."
"My AI has my entire email history. It's like texting my past self who actually remembers everything. Made $840 last month."
"I thought this was creepy. Then my AI answered a question using an email from 2015 I completely forgot about. Now I get it."
"WhatsApp chat with my own brain. Runs on my old Mac Mini in the closet. People pay me $30/hr to chat with it. Future is weird."
"Built it on Sunday. By Tuesday it had learned my entire writing style from 50k emails. By Friday someone paid $50 to get advice from it."
"This is the closest thing to a second brain I've ever used. And it pays me."
"20 years of case notes, client emails, and legal research. My AI drafts better briefs than my junior associates. They now use it too."
"Fed it every client email I've ever sent. Now when someone asks about my process, my AI explains it better than I do. $320 last week from design consultations."
"My AI learned from 12 years of my teaching materials. Students chat with it on Discord at 2am before exams. I wake up to Venmo notifications."
"My AI knows every architecture decision I've made in 18 years. New hires ask it why we built things a certain way. It remembers what I forgot."
"10 years of market commentary in my email. My AI now gives better takes than half the newsletters I subscribe to. Charging $25/hr for access."
"8 years of session notes. My AI handles intake questions on WhatsApp while I'm with other clients. Converts 40% of them to paid sessions."
"15 years of lesson plans and student Q&A. Parents pay $10/month for their kids to chat with my AI for homework help."
"Every negotiation email, every market update I've sent in 11 years. My AI helps first-time buyers on Telegram. Made $1,200 last month in referral fees."
"My AI has every PRD, sprint retro, and stakeholder email I've written. Junior PMs on my team ask it questions before asking me. Everyone wins."
"6 years of meal plans and training programs. Clients text my AI at midnight asking what to eat. I sleep great."
"20 years of recipes, supplier contacts, cost spreadsheets. My AI handles vendor questions and menu planning. It's like having a sous chef that knows everything."
"My AI knows every investor pitch, every pivot, every post-mortem. First-time founders pay $40/hr to pick my brain. Except it's not even me answering."
"22 years of repair notes and parts orders. DIY guys chat with my AI on WhatsApp before touching their engines. $15/hr, 30 hours last month."
"Every project spec, city code reference, and client revision for 14 years. My AI saves me 2 hours a day just answering code compliance questions."
