We built gbrain for ourselves first

We wanted open source AI tools that work harder than we do.

How it started

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.

None of them were built for a team, either. We wanted one thing all three of us could prompt together, which is why gbrain is multiplayer.

Getting it running meant the three of us in a room pasting API keys in one at a time. Nobody else was going to sit through that, so we built gbrain.io: the same thing, on a machine of its own, in about two minutes.
