How to Switch from ChatGPT to Claude Without Losing Your Memory
This past week, OpenAI introduced ads into ChatGPT for free and Go tier users, retired the beloved GPT-4o model that millions of users had formed deep connections with, and prompted one of their own researchers to quit and publish a New York Times op-ed titled "OpenAI Is Making the Mistakes Facebook Made. I Quit."
If you're reading this, you're probably one of the people thinking about leaving. This guide is for you.
I'm Asad, the founder of MemoryPlugin, a cross-platform AI memory tool. I went through this exact transition myself. Earlier in 2025, ChatGPT was my primary platform. Then GPT-5 came out, and I didn't vibe with it. It was better at coding, sure — but at the cost of everything else. It was worse at intuitive understanding, less capable with nuance, more lectury, more moralizing. I found it much harder to shape to my liking.
This is the exact concern a lot of people have right now. After massive backlash, OpenAI brought GPT-4o back — but only temporarily. As of February 13, that time is up. GPT-4o is gone for good, and conversations will default to GPT-5.2 going forward.
So I switched to Claude. Here's everything I've learned about making that transition — what you gain, what you lose, and how to bring your data with you.
Why Claude Is Worth the Switch
Claude is built by Anthropic, one of the frontier AI labs. Both Claude Pro and ChatGPT Plus cost $20/month, so the price isn't a factor — the question is what you get for it.
Subjectively — but widely agreed upon by a lot of people — Claude has been the best-in-class model for almost a year and a half. I don't put much stock in benchmarks anymore; they're so heavily gamed at this point that they're worse than useless. What I care about is how a model feels to use every day.
In my experience, coding is where Claude really shines. The Claude Sonnet and Opus models are a genuine step above GPT-5 Codex and Gemini Pro. They require way less handholding and can infer much more from less specific prompts. They seem to get you intuitively in a way that ChatGPT and Gemini don't.
Talking to Claude is more like talking to a coworker you've worked with for years — you share a lot of context, you can speak in shorthand, and you don't have to spell everything out. With ChatGPT and Gemini, unless you're very precise about what you want, the model might produce something that works, but it's unlikely to match what you actually had in mind.
This isn't just about coding either. In regular conversation, Claude seems to understand what you mean in a way other models don't. You can be pretty high-level and vague, and Claude will accurately figure out your intent. Other models need you to be much more specific or they'll misunderstand you.
Claude is also excellent at agentic workflows. When you give it a task, it's great at figuring out the intermediate steps and executing them in a self-correcting way. If it needs to change direction mid-course, it will.
One thing worth knowing about the company behind Claude: Anthropic does some of the most respected research in AI interpretability — the field of understanding how AI models actually work internally. They publish this research openly, and it's part of what makes Claude's outputs feel so considered. When a model is built by people who deeply understand how these systems think, it shows.
What You'd Be Giving Up
Let's be honest about the trade-offs.
Advanced Voice Mode. ChatGPT has a genuinely impressive real-time voice mode that supports video calls. The GPT models generate audio output natively — it's emotive, fast, and feels like an actual conversation. On Claude, voice works through speech-to-text and text-to-speech. Your speech gets converted to text, the model outputs text, and that gets converted back to speech. It's slower, and the emotional nuance from your tone is lost in translation. It's not terrible — it's what standard voice mode was on ChatGPT — but it's not on the same level.
Image and video generation. Claude can't generate images natively. There's no DALL-E equivalent, no Sora for video. You can work around this with third-party tools and MCP integrations, but it's not built in.
Usage limits. Claude's usage limits are tighter than ChatGPT's. On Claude Pro ($20/month), you get roughly 45 messages per 5-hour window. ChatGPT Plus gives you more headroom. This is partly because Claude's models are larger and more computationally expensive to run, and partly because OpenAI subsidizes usage more aggressively — even on the $20 plan, you're likely consuming several hundred dollars' worth of compute per month. Claude subsidizes too, but less so. If you're a heavy user who hits limits frequently, Claude's Max plan ($100 or $200/month) removes most of these constraints.
Personality. Claude does not have the same personality as ChatGPT. It's less energetic, more warm, and less talkative. If you loved GPT-4o's enthusiastic, affirming style, Claude will feel different. That said, Claude is very malleable in its personality — you can shape it to your liking through custom instructions and style settings. GPT-5.2, by contrast, is much more resistant to personality customization.
What Happens to Your Data When You Switch?
Here's the part most people are worried about. By default, none of your ChatGPT data survives the move. But it can be managed.
Here's what you'd lose without taking action:
- Your entire chat history
- Your saved memories
- Your custom instructions
- Your projects and folders
- Your Custom GPTs
Let me walk through how to handle each one.
Projects and Custom Instructions
This is the easy part. For any projects you had on ChatGPT, you can recreate them as Projects on Claude. Download any files that were uploaded as project knowledge on ChatGPT, upload them to a Claude Project, set your custom instructions, and it'll work essentially the same way.
Chat History and Memories — The Hard Part
This is where it gets real. Claude doesn't let you import data from ChatGPT. And this is where I can speak from personal experience.
When I moved to Claude, I had thousands of conversations on ChatGPT. I'd discussed everything — my ambitions, my strengths, my challenges. I'd planned features, debugged problems, made decisions, worked through product strategy. All of that context was sitting in ChatGPT, and Claude had no idea any of it existed.
Here's the thing about AI memory that I think about a lot: the difference between a friend and a stranger is shared memory. A friend knows about you, understands you, has context for who you are. That's what makes their advice so much more helpful — not because they're smarter, but because they understand you. A stranger doesn't know who you are, so even brilliant advice lands differently.
Having Claude's intelligence without years of context is like having a brilliant new coworker who doesn't know anything about the project yet.
So I used MemoryPlugin to bridge the gap. I imported my ChatGPT chats into MemoryPlugin, installed the Remote MCP Server into Claude, and sat down to work on refining my marketing and product strategy for MemoryPlugin itself. I was able to ask Claude to pull in details about how I originally came up with the idea, how the product evolved over time, what major features were added and why, how I'd marketed it, and what had worked and what had failed.
I dogfooded MemoryPlugin to grow MemoryPlugin. And it worked — because all of that historical context, which would have been trapped in ChatGPT forever, was now available to Claude.
How MemoryPlugin Works
Importing your chat history: You can import your ChatGPT chats into MemoryPlugin and make them available to Claude via our Remote MCP Server. This works on Claude's web app, desktop app, mobile app, and even on Claude Code and Claude CoWork.
Syncing your memories: With a single button click, you can sync your ChatGPT memories into MemoryPlugin and make them usable from Claude. It takes minutes.
Going forward: With our browser extension (Chrome and Safari), you can connect both your ChatGPT and Claude accounts to automatically sync new chats into MemoryPlugin. This gives you complete cross-platform search and context going forward.
Natural language search: Unlike the keyword search that ChatGPT and Claude offer natively, MemoryPlugin lets you search your conversations using natural language. You can search for something like "the conversation where I discussed marketing strategy for my new side project" and actually find it. You can filter by platform, chat size, time range, and more.
There's no complicated setup. No command-line tools. No servers to configure. It's designed to be straightforward for AI power users.
The Bigger Picture
Here's what I think most people miss about this moment. The best AI model changes regularly. Right now, Claude leads in coding, GPT-5.2 leads in abstract reasoning, and Gemini 3 Pro leads in speed and multimodal tasks. Six months from now, the landscape will look different again. There is no permanent all-rounder.
If all of your data is siloed into one platform, you can't make the most of AI. You're locked in — not because the platform is the best, but because your history is trapped there. That's exactly the position millions of ChatGPT users are in right now: wanting to leave, but feeling like they can't afford to start over.
With MemoryPlugin, we break open that silo. We give you control and ownership over your relationship with AI, no matter what platform you're on. That's the philosophy that drives everything we build.
You shouldn't have to choose between the best model and your own memory.
