foxmate
an open-source personal agent that runs in your own firefox
the problem
cloud agents run in a virtual machine in the vendor's cloud. to act for you, they need copies of your logins there.
what i built
foxmate is a firefox extension. you type a goal in the sidebar, and an ai planner works on the current tab with your logins, on your computer. it shows each step and asks before it sends a form.
