Mnemoverse Memory for ChatGPT
Keep contact details from the people you meet and save the project decisions you want to find again in a later chat. For a shared project, you can choose which notes to put in a room with a colleague.
Install the published plugin
Open Mnemoverse Memory in ChatGPT →
Open the card. If you see Install plugin, select it. If you see Try in chat, select that to open a conversation.
When prompted, sign in to ChatGPT and connect your Mnemoverse account in the browser. Use the same Mnemoverse account across the tools where you want to recall these notes.
With Mnemoverse Memory selected in ChatGPT, try this in an empty chat:
Help me save a project brief. Ask me what the project is, what we decided, and what comes next.
Give it the details you want saved. Later, select Mnemoverse Memory in a new chat and ask for the next step by project name. You can also start with a photo of a business card.
Save and check a memory
Once connected, ask Mnemoverse to save the information you want to keep. The assistant calls memory_write, checks the result, then uses memory_read to verify it. A successful memory_stats call alone does not test writing.
From a business-card photo to a saved contact
After you ask to save a card, the assistant should use the visible contact details and the exact domain you requested. It should ask about unclear text, and should not replace your card's details with an example.
With the card photo attached, you can say:
Use Mnemoverse Memory. Save the contact details exactly as printed on this card in the domain "Web Summit 2026", then read the contact back to verify it.
If the plugin is not connected, the assistant should first give you the install link above and keep the contact as an unsaved draft. You complete login and consent yourself; do not paste a password, API key or OAuth code into the conversation. The printed card alone is not permission to install or save.
Say saved only after a successful write result, and verified only after reading the contact back. A message in chat or ChatGPT's built-in memory is not a Mnemoverse write.
If it does not work
To check the connection, ask Mnemoverse Memory to show your memory count. A successful memory_stats response confirms read access. Installation uses browser sign-in and needs no API key or custom MCP configuration.
| What you see | Next step |
|---|---|
| Neither Install plugin nor Try in chat is visible | On a phone, open the card in a browser using the same ChatGPT account. Check the exact message about availability or workspace restrictions. |
| Installed, but no Mnemoverse tools in this conversation | Start a new conversation and select the installed plugin. |
| Sign-in required or authorization error | Complete or reconnect the Mnemoverse browser sign-in, then retry memory_stats. |
| Stats works, but saving fails | If Mnemoverse declines the write, report its reason. If the request times out, the outcome is unknown. Check before trying again. |
| Write succeeds, but read-back fails | Report that saving succeeded but verification is incomplete. Check the same account and exact domain before trying again. |
For help, send the visible error and whether you used the mobile app or browser to [email protected]. Do not include credentials.
Cross-Tool Proof
Use the same Mnemoverse account in both tools. Memory belongs to the account, not to the tool or the key. A different account opens a separate, empty memory, and nothing shows an error (why). Save a harmless test fact with an exact domain in one tool, then read it from that domain in the other. Different memory counts can suggest an account or scope mismatch; they do not prove which account is connected.
Alternative setups
Only use these if you deliberately need a custom integration. Their creation permissions do not determine whether you can install the published plugin.
Custom MCP server
Custom MCP server setup — manually configure the endpoint and browser authentication.

Custom GPT with Actions
Custom GPT Actions setup — the separate REST/API-key integration for existing or eligible custom GPTs.

Tools available in ChatGPT
The published plugin uses the hosted memory tools. Tool availability lists the deliberate host differences; custom GPT Actions have their own action names.
