xAI lists memory across chats as a Grok feature, but the xAI pages we checked don’t explain how it works or how to manage it. Dray saves your grok.com chats to your own Dray account, where every assistant and agent you connect can search them.
xAI’s Grok page lists “Memory across chats: Remembers your preferences and past conversations”, and custom instructions. xAI: Grok

What Dray adds
Dray for Chrome saves your chats on grok.com, with their titles and dates and the files and images in them. One switch turns files off. Dray privacy policy
Chats in the Grok phone app are saved too, while Chrome is running and signed in to the site. The extension reads them from the site in the background, with no tab open: about once a minute while the computer is in use, and every 15 minutes when it is idle or locked. It starts from when it is turned on; older chats come in through “Read my history”. If the site is signed out in Chrome, or Chrome is closed, those chats wait until that is fixed. Dray help
Added as a connector, Grok can search what you saved from ChatGPT, Claude and your coding agents. Dray: connect
Grok Build gets the connection too: if you connected Dray on grok.com, Grok Build lists it in /mcps as Dray (managed). See Grok Build memory. Dray: connect
You choose how far back Dray reads, from the last three days to all of your history. When you delete a chat in Grok while Dray is running, Dray deletes it from your memory too. Dray helpDray privacy policy
On a saved chat, the Dray menu offers “Ask ChatGPT about this chat” (or Claude), listing only assistants you have connected. It opens that assistant with the request typed, and you press Send yourself. Dray help
You can also import a Grok export from your dashboard. Your browser reads the file and sends Dray the text of your chats and the names of attached files, never the files themselves. Dray privacy policy
Saving chats needs Chrome (116 or later), Edge, Brave or Opera on a computer. Safari, Firefox, phones and tablets can’t install the extension. Dray help
Reading may miss or misread chats, and memory extraction can be wrong.
Some business plans switch MCP off or allow only approved servers. Dray: connect
Dray learns from 1,000, 5,000 or 20,000 of your messages a month, depending on your plan. Going over deletes nothing; new messages wait until the month resets or you move up. Dray: usage
