Give ChatGPT and Claude the same memory
Use the browser extension so ChatGPT, Claude, Gemini and Perplexity share one memory.
ChatGPT and Claude do not share what you tell them. The Hivemind browser extension adds your relevant memories to a prompt before it is sent, and saves what is worth keeping from what you write.
Install the extension
Download it from the Hivemind site, unzip it, open
chrome://extensions, turn on Developer mode and choose Load unpacked.
A Chrome Web Store listing is on its way. Open the extension and press
Sign in.
Use it
ChatGPT, Claude, Gemini, Grok, Perplexity and T3 work straight away. Tell one of them something:
Our newsletter goes out on Tuesdays, and Sarah signs off first.
Later, in another:
Can we send the newsletter tomorrow?
A brief note says how many memories were added to the prompt, and What? shows which ones.
Control what is saved
Every save shows a two-second note you can cancel, and everything kept is listed in the dashboard where you can edit or forget it. The extension only works on sites you have switched on.
