About the startup

GBrain gives you a memory and a set of connected accounts that every AI can reach. Write a note in Claude Code and ChatGPT knows it. Connect Gmail once and Cursor can search it with no key in a config file. The memory is a folder of markdown files you can read, correct and take with you. Run it on your own inference or ours, in a workspace your whole team shares. $100 off the first month for a team workspace at https://gbrain.io/gratis/product-hunt
