The three of us met building Garry's List. Every time we moved between AI tools we pasted the same API keys into the next one and explained the work all over again.
No existing tools were built for a team, either. We wanted one thing all three of us could prompt together, which is why gbrain.io is multiplayer.
Initially, building this meant the three of us in a room spinning up an agent harness, initializing memory; installing skills, manually setting up integrations to external tools, and pasting API keys in one at a time.
After copy-pasting that setup for a bunch of our friends, we built gbrain.io for the world: the same thing, in the cloud, that sets itself up in one click.
