🤖 Why I stopped using ChatGPT

Not because I stopped using AI. Quite the opposite. I found something that actually works the way I need it to.

It's called Claude Cowork. I'm going to tell you why I switched, what I've built with it, and how you can do the same — no coding required.

Give me a few minutes.

Here's the problem with ChatGPT.

You give it a detailed prompt. 500 words of context. Specific requirements. Formatting, structure, things you want and things you don't — clear, specific instructions it just decides to ignore.

It ignores half of it.

You remind it. It apologizes. Then ignores the other half. And I'm far from the only one saying this — the OpenAI forums are packed with reports like this one.

With Claude Cowork, I upload my voice profile. Over 2,000 words describing how I write, what I hate, phrases I never use, structures I prefer. I upload my copywriting rules. My reference documents.

It reads all of it. It follows all of it.

When I write with Claude Cowork, the output sounds like me. Not "AI trying to sound like me." Me. And head-to-head comparisons between Claude and ChatGPT are clear: for writing, Claude wins.

Why does this matter? Because the quality of your output depends on how much context you can feed it. If the AI ignores your context, you're stuck with generic results. Forever.

You know the feeling.

You're 45 minutes into a complex task. ChatGPT starts repeating itself. Contradicts what it said earlier. Gets stuck in a loop where it apologizes and spits out the same broken output — as if it's starting from scratch, forgetting everything you already worked on together.

You open a new chat. Feed it all the context again. Or just give up. Long conversations become a nightmare of degraded performance and lost context.

I've had 2-hour sessions in Claude Cowork. Revisions, pivots, constant back and forth. And it doesn't lose the thread.

But here's what really gets me: when it sees I'm not happy with what it's giving me, it throws me a form asking what I want to change. The AI is prompting me.

I'm telling you this because it completely changes what's possible. If your AI breaks after 20 minutes, you can only do small tasks. That's a ceiling. And with Claude Cowork, that ceiling disappears.

Yeah. This is a feature, not a bug.

ChatGPT remembers your past conversations. Sounds useful.

But it creates an overfitting problem.

It tries too hard to match what you said last week. Makes assumptions based on old context that no longer applies. It adapts so much to what it thinks you want that it ends up being worse. ChatGPT's memory mixes contexts in ways nobody asked for — users reporting that memories from one conversation bleed into a completely different one.

Claude Cowork starts fresh every time.

No baggage. No assumptions from three weeks ago.

If I want it to know something, I give it that context myself. In this conversation. For this task. With my markdown files to back it up.

I decide what matters. Not some algorithm guessing based on a conversation I don't even remember.

Would it be great to have an AI that knows exactly when to pull from past conversations? Sure. But it doesn't work that way. And instead of fighting it, better to use AI the way it works best: when you control the full context before you start.

Tired of introducing yourself every time? Create a markdown file with everything about you and upload it at the start of every conversation. Problem solved.

This is the big one.

ChatGPT gives you text. You copy it. Paste it into another tool. Format it yourself.

Every. Damn. Time.

Claude Cowork creates the actual files. Cowork isn't just another chatbot — it's an agent that works directly on your desktop.

I ask for a presentation. I get slides. Real slides.

I ask for a spreadsheet. I get an Excel file with working formulas.

I ask for a document. I get a formatted Word file, ready to go.

The files show up in my folder. I open them. They're done.

It's not "text you then turn into something useful." It's the final file. Ready to use, ready to send.

There's a difference that seems subtle but changes everything.

You ask ChatGPT to do something and it explains how to do it. Gives you the steps. Says "you could try this, then do that." Dude, I didn't ask for a tutorial. I asked you to do it.

Claude Cowork does it.

Convert a file? It converts it. Transform data from one format to another? It transforms it. Doesn't ask for permission or hand you a walkthrough. It sees it can do it and it does it.

I love that. That proactiveness is the difference between an AI that assists you and an AI that works with you. That mental shift from "assistant" to "coworker" is real.

I needed a presentation with my newsletter's data. I had a reference deck I liked — the format, the structure, the length.

I gave that presentation to Claude Cowork. Gave it my brand colors. Gave it my data.

It gave me back the presentation, replicated. With my branding. With my numbers. Done.

I didn't open PowerPoint. I didn't tweak fonts or colors by hand.

But the best part isn't that it was fast. The best part is that it works autonomously. Once it has the information it needs, it gets to work. It doesn't stop you every two seconds with "do you want this? how about that?" It just does it.

And you? You're doing something else.

I don't care if it takes one minute or ten. Because I don't have to babysit it. That's working with an AI, not for an AI.

I was converting my book (Master ChatGPT in 3 days, #1 in Computer Literacy Amazon USA) to audio format. I generated each chapter separately with ElevenLabs — and I'm not the only one: indie authors are already producing full audiobooks with ElevenLabs for under $200.

The result: a bunch of loose audio files. One per chapter.

I gave the same prompt with the same files to ChatGPT. Know what it did? Explained how I could do it myself. "You could use this program, or maybe this other option, or you could also download this thing..." Option A, option B, option C. A lot of words.

Know what Claude Cowork did? It said "here's how this works, hold on, I'll do it."

And it did.

It took around 20-30 minutes. I'll be honest, I thought it wasn't going to pull it off. But when I downloaded the final file and saw it worked — that it had merged all the audio files, converted them to the right format for the platform, and even asked me for a cover image for the audiobook — I was blown away. And you can now distribute those audiobooks directly on Spotify.

I didn't look up software. I didn't follow tutorials. I didn't open an audio editor.

I gave it the files and it handled everything.

This one changed how I work more than anything else.

When people think about replicating their voice with AI, what they usually do is dump a bunch of their writing and say "extract my voice." That's the typical approach. And it's lazy. There's a specific method to make AI learn to write like you that works much better.

I have a much better way.

A prompt that makes Claude Cowork ask you questions. It gets to know you. How you write, what you hate, what structures you use, what your tone is. Question after question, it builds your voice profile.

The result: a document with over 2,000 words describing exactly how I express myself. And now, every time I ask it to write something, I upload that file. The output sounds like me. Not like AI. Like me. Claude can clone your writing style with an accuracy that's almost scary.

And you know why this doesn't work the same in ChatGPT? Because the conversation is long. Really long. And ChatGPT loses context halfway through. Claude Cowork holds it perfectly, no matter how long the session runs.

In an upcoming post I'm going to show you exactly how I did it, step by step. I think it's one of the most useful things you can do with AI right now.

It's not. Nothing is.

But it changed how I work more than any tool since the original ChatGPT launch.

And here's a thought I think is important.

It's no longer about who has the most powerful model. We're not waiting for the next GPT-6, more parameters, more benchmarks. The race isn't just about the model anymore. It's about what you build on top of it. And models are becoming commodities — the real advantage is in the product.

And that's exactly what Anthropic did with Cowork. They took a powerful model like Opus 4.6 and gave it superpowers: creating files, being proactive, connecting with your tools, working autonomously. That's not model power. That's product engineering. The model is no longer the competitive edge — workflow integration is.

The model alone is fine. What makes it extraordinary is everything they let it do.

And I don't care if tomorrow ChatGPT releases its own Cowork, or Gemini integrates better with Google Drive. What you learn here applies to whatever AI comes next. This is a way of working, not a specific tool. ChatGPT's market share dropped from 86% to 64% in a single year — something is shifting.
