The proposal happened six months ago. Beautiful. Perfect. Everything I dreamed about since I was little.
Then came the hard part: planning an entire wedding.
My fiancé worked sixty-hour weeks at his law firm. I managed a small bakery. Neither of us had time to plan a wedding. My mom suggested hiring a wedding planner, but they wanted five thousand dollars just to start.
“There has to be a cheaper way,” I told my best friend over coffee.
She pulled out her phone and showed me something called ChatGPT agent mode. “It’s this new AI thing,” she explained. “People are using it to plan entire vacations, book restaurants, and even organize parties. Why not a wedding?”
I laughed. “You want a robot to plan my wedding?”
“It’s not a robot. It’s like having a really smart assistant who works for free. It can search venues, compare prices, make spreadsheets, everything.”
That night, I looked into it. Turns out, lots of people were already using AI agents for complex tasks. The technology could browse websites, fill out forms, and even book appointments.
What did I have to lose?
How ChatGPT Agent Mode Works
Setting up the agent was easier than I expected. I paid for the premium subscription and activated agent mode through the dropdown menu. The interface looked normal at first, just the regular chat window.
But this was different. This AI could actually do things.
I started with a simple task: “Find wedding venues in our area that fit 150 people and cost under ten thousand dollars.”
The agent went to work immediately. I watched it browse through venue websites, check availability calendars, and compile everything into a neat spreadsheet. Fifteen minutes later, I had a complete list with prices, dates, and contact information.
“This is amazing,” I whispered to myself.
Over the next few weeks, I gave the agent more tasks. Book appointments with florists. Compare catering companies. Find the best deals on wedding decorations. Research honeymoon destinations.
The AI handled everything. It could log into websites, navigate booking systems, and even draft emails to vendors. One time, I asked it to schedule venue tours, and it coordinated with five different locations in a single afternoon.
My fiancé was impressed. “Honey, you’re crushing this wedding planning thing.”
I smiled but didn’t tell him the truth. I wasn’t doing any of it. The AI was.
When Things Started Getting Strange
Three weeks before the wedding, I asked the agent to do something routine: “Check our wedding registry and make sure everything’s organized properly.”
The agent logged into our registry account. Normal procedure. It had done this before.
But this time, something happened.
“I found an issue with your registry,” the agent messaged back. “There appears to be a duplicate account under a similar name. Would you like me to investigate?”
Duplicate account? That didn’t make sense.
“Yes, please check it out,” I typed.
The agent went silent for a few minutes. When it responded, my stomach dropped.
“I found a second wedding registry. Same groom name. Different bride name. Wedding date: two weeks after yours.”
I stared at the screen. My hands started shaking.
“Show me,” I demanded.
The agent pulled up screenshots. There it was. My fiancé’s full name. A woman named Jennifer. A wedding date set for December 15th. Our wedding was December 1st.
The registry had expensive items. Honeymoon funds. Everything looked real.
This had to be a mistake. Maybe someone with the same name? Maybe a glitch in the system?
“Search for this Jennifer and cross-reference with my fiancé’s social media,” I instructed the AI.
The agent mode technology went to work. It browsed Facebook, Instagram, LinkedIn. Within minutes, it found her.
Jennifer. A lawyer at the same firm where my fiancé worked.
Photos of them together at office parties. Comments on her posts from two years ago. Recent pictures from just three months back.
My heart felt like it stopped.
What the AI Revealed
I sat there staring at my computer screen for what felt like hours. The chatgpt agent mod had uncovered something I never would’ve found on my own.
The technology had been so efficient, so thorough, that it connected dots I didn’t even know existed.
I asked the agent to dig deeper. “Find any shared reservations, bookings, or accounts between these two people.”
Twenty minutes later, the agent presented its findings:
A joint hotel reservation in Hawaii. Dates: December 16-23. Two weeks after our wedding. Same place we were supposed to honeymoon, just different dates.
Shared meal delivery service account going back eight months.
Venmo transactions between them with heart emojis.
The AI had essentially done detective work I couldn’t have managed myself. It browsed multiple websites, connected information across platforms, and presented everything in an organized report.
This was what people meant when they talked about AI agents doing complex research tasks. The technology didn’t just answer questions. It investigated. It made connections. It solved problems.
Unfortunately, the problem it solved was that my fiancé was living a double life.
Confronting the Truth
I printed everything. Every screenshot. Every receipt. Every piece of evidence the AI had gathered.
When my fiancé came home that night, I had it all spread across our kitchen table.
“What’s this?” he asked, his face going pale.
“Why don’t you tell me about Jennifer?” I said quietly.
He tried to lie at first. Said it was a misunderstanding. Said the AI must have made mistakes.
“AI doesn’t make mistakes like this,” I told him. “It found your shared hotel booking. Your Venmo history. Your duplicate wedding registry.”
He sat down. Put his head in his hands.
The truth came out slowly. He’d been seeing Jennifer for a year. They worked together. Started as friends, became more. He’d proposed to her four months after proposing to me.
“I didn’t know how to choose,” he said pathetically. “I loved you both. I thought I could figure it out.”
His plan? Marry me first. See if it felt right. If not, call it off and marry Jennifer two weeks later. If it did feel right, ghost Jennifer and pretend she never existed.
The chatgpt agent mode had exposed the entire scheme by simply doing what I asked: organizing our wedding details.
Life After the Discovery
I called off the wedding the next day. Contacted all the vendors. Canceled everything.
The hardest part was telling people why. My mom cried. My dad wanted to drive to my ex-fiancé’s office and confront him.
“Don’t,” I said. “He’s not worth it.”
My best friend, the one who suggested using AI for wedding planning, felt terrible. “I’m so sorry. I never thought—”
“Don’t apologize,” I interrupted her. “You actually saved me. If I’d hired a regular wedding planner, none of this would’ve come out. I would’ve married him. Maybe found out years later. Maybe never found out at all.”
She was right. A human planner would’ve just planned the wedding. They wouldn’t have stumbled across registry duplicates. They wouldn’t have cross-referenced social media accounts.
Only an AI agent—something designed to be thorough, to connect information across multiple platforms, to investigate without bias—could have uncovered something like this.
The technology people were using to book vacations and plan parties had accidentally become my private investigator.
Understanding What Happened
Over the following weeks, I learned more about how chatgpt agent mode actually works. The technology uses something called a virtual computer. It can browse websites using both visual and text-based browsers. It can log into accounts, navigate forms, and pull information from multiple sources.
When I asked it to check our wedding registry, it did exactly what any thorough assistant would do: it looked for problems. When it found the duplicate account, its programming told it to investigate further.
The agent didn’t know it was uncovering infidelity. It just knew there was an inconsistency in the data. So it dug deeper, following the trail wherever it led.
That’s the thing about AI agents. They don’t have emotions. They don’t get tired. They don’t ignore red flags because they’re in love. They just follow the data.
People were using this technology for business tasks, for productivity, for convenience. I’d accidentally used it for truth.
Moving Forward
Three months have passed since everything fell apart. I’m doing better now. Some days are harder than others, but I’m healing.
I still use AI tools, actually. They help me run my bakery more efficiently. I use them for scheduling, inventory management, and customer service tasks.
But I’ll never forget what happened with the wedding planning. How a piece of technology designed to make life easier ended up revealing a devastating truth.
Sometimes I wonder what would’ve happened if I’d never used chatgpt agent mode. Would I have married him? Would I have found out eventually, or would he have gotten away with it?
The AI didn’t just save me time and money on wedding planning. It saved me from making the biggest mistake of my life.
What This Experience of Using ChatGPT Agent Mode Taught Me
Technology is powerful. More powerful than most people realize. These AI agents can do incredible things—plan events, analyze data, automate tasks. Businesses are using them to save hundreds of hours every month.
But they can also reveal truths we weren’t looking for.
I’m not saying everyone should use AI to investigate their partners. That’s not what this story is about. But I am saying that as technology gets smarter, as these tools become more capable of connecting information across the internet, we need to understand what they can do.
The ChatGPT agent mode feature isn’t just about booking restaurants or creating spreadsheets anymore. It’s about giving AI the ability to think through complex problems, to browse multiple websites simultaneously, to piece together information in ways humans might miss.
That’s powerful. And sometimes, like in my case, that power reveals uncomfortable truths.
I’m grateful for what happened, as painful as it was. Better to find out before the wedding than after. Better to face the truth than to live a lie.
And yes, it’s ironic that a machine—something without feelings, without a heart—showed more loyalty to me than the man I was going to marry.
Sometimes the things we create to make our lives easier end up teaching us the hardest lessons.
