I'm building Charter, which lets you decide what your agent sees, sends and gets back, in every API it touches.
Since 2024 I've run agents inside the real Gmail, Calendar, Docs and Sheets of ~280 people. That was SurfBuddy, built solo, and the most fun I've ever had. Charter is the hardened plumbing underneath it, now open source under Apache 2.0.
