In a recent LinkedIn post, Ruben Hassid addresses a common challenge for users of advanced AI chatbots: transferring conversation histories and memories between different platforms. Hassid, a proponent of practical AI solutions, highlights the perceived similarity between popular models like Claude and ChatGPT, while acknowledging the technical hurdles involved in switching between them.
Hassid frames the issue by posing relatable scenarios: “I’m sure there is someone around you who asked you this, this week: ‘I love the new GPT-6 Astra, but how do I switch from Claude to ChatGPT?’” He further elaborates on the need for such a guide, noting that users might wish to dedicate specific AI tools for different purposes, such as using ChatGPT for personal queries and Claude exclusively for professional work.
To demystify this process, Hassid has created a free guide and shared key steps on LinkedIn. He emphasizes that while the platforms are comparable in capability, the transition isn’t always intuitive. As Hassid points out:
“But how can you very simply switch from one to another, well turns out it takes a few steps.”
Migrating from Claude to ChatGPT
Hassid outlines a method for users looking to move their conversation history from Claude to ChatGPT. The process involves exporting data from Claude, specifically requesting 90 days of conversation history. Once the data is received via email and unzipped, users can upload these files into a new Claude chat. Hassid provides a specific prompt designed to consolidate the entire chat history and memories into a single Markdown file, which he labels “Claude-to-ChatGPT .md”.
According to Hassid, this consolidated file can then be uploaded to the ChatGPT interface, where users can instruct the AI to save it to its memory, effectively transferring the historical context.
Transferring from ChatGPT to Claude
The reverse process, moving from ChatGPT to Claude, involves a different set of instructions. Hassid directs users to a specific settings page within Claude.ai. There, they can find and copy an export prompt provided by Claude. This prompt is then to be pasted into ChatGPT. Hassid explains that ChatGPT will then generate the user’s memories in a code block format.
The next step, as detailed by Hassid, is to paste this output back into Claude, adding it to the AI’s memory. For users who also utilize ‘Skills’ or ‘Codex’ features, Hassid provides instructions for exporting these from their respective folders as zip files and then uploading them into Claude’s ‘Customize’ section under ‘Skills’.
Hassid’s detailed breakdown aims to empower users to leverage their AI tools more effectively by enabling seamless data migration. He states:
“I won’t go into details on Linkedin, I don’t have enough characters to give you all of the steps, but it goes like this:”
Hassid’s initiative underscores the growing importance of interoperability in the rapidly evolving AI landscape. By providing practical, step-by-step instructions, he offers a valuable resource for individuals and professionals seeking to optimize their use of AI assistants.
As Ruben Hassid notes, the ability to switch between these powerful tools can enhance productivity and personal workflow management:
“It turns your whole history + memories into ONE Markdown file: Claude-to-ChatGPT .md”
