AI was built for one. Work was never meant to be.
The most powerful tool of our generation shipped as a single-player game.
One person, one chat box, one tab. Everyone has their own. And so the best thinking happening inside companies right now are prompts. Back-and-forth happens in private and vanishes the moment the tab closes. We've seen this before. Documents were single-player until they weren't. Design was single-player until it wasn't. Every time work moved into a shared, real-time space, teams got faster and the tools got better. AI is the last great category still waiting for that shift.
So we're building it.
Additional is a workspace where your team, your tools and any model think together. Not AI bolted onto an old app. Not a smarter chat box. A space built from scratch for the way teams actually work together, in context, building on what came before. We believe collaboration shouldn't stop where AI begins. We believe you shouldn't be locked to one model, or forced to copy-paste your own company into a prompt. We believe the value isn't in the model. It's in the shared space around it, getting smarter every day your team uses it. The tools you use should know your team. They should remember your decisions. They should get better the more of you are in the room.
That's the workspace we're building. Come build with us.
A and D, Founders of Additional
