Switching from ChatGPT to Claude usually means starting over: everything you explained, decided and corrected stays behind. It does not have to. Export your ChatGPT history, import it on your phone, connect Claude, and Claude can recall what you told ChatGPT, word for word and with the date you said it. About ten minutes, no account, free.
1. Install GrantAi Remembers on your phone
GrantAi Remembers keeps one memory in the app's private storage on your phone and shares it with the AI agents you connect. Get it from the product page. Open it once; it is ready in a few minutes after it downloads its search models over Wi-Fi.
2. Export your history from ChatGPT
Open chatgpt.com, choose your profile picture, then Settings, then Data controls.
Choose Export data and confirm. ChatGPT may ask for your sign-in code.
Within a few minutes an email arrives with a download link. Download the file; it is a zip that holds conversations.json.
3. Import it on your phone
In GrantAi Remembers, open the Memory tab and find Bring your chat history.
Choose the export file and pick the zip ChatGPT emails you.
The app reads the file on the phone and adds your conversations newest first. You can keep using it while that runs; agents can already recall what has been added.
Each exchange is kept word for word with its original date. The file never leaves your phone.
4. Connect Claude
In GrantAi Remembers, tap Claude. The app opens Claude with the setup message typed; send it.
In Claude, open Customize, then Connectors, and choose Add custom connector. Name it GrantAi and paste the address the app showed you.
Choose Connect and approve the request on your phone.
In a chat, switch GrantAi on from the tools menu once.
When Claude lists GrantAi Remembers in its own connector directory, this step is one tap plus a six-digit code.
5. Ask Claude something you told ChatGPT
Try a detail only ChatGPT knew: a project name, a decision, a preference. Claude checks your memory before answering and tells you what it found. From now on, what you tell Claude is saved the same way, so the next agent you try starts with everything too.
What carries over, and what does not
Your conversations with ChatGPT carry over, in your words, with their dates.
ChatGPT's own summary memory is not in the export, so it does not; the conversations it was built from do.
Claude keeps its own memory as before. GrantAi is the memory your agents share; it adds to each one, it does not replace it.
You can disconnect any agent in the app at any time. Its access ends immediately.
