apps were a workaround. agents don't need menus. here's where we think the digital world is going — and the quieter path we're building toward it.
Before AI, the only way a computer could help you was a screen, a menu, and buttons. Every app you use today was designed for a human to drive.
We made peace with that. We install ten of them. We tab between them. We hold the context in our heads. The cost was invisible because there was no alternative.
MCP and tool-use let an agent talk directly to Gmail, your calendar, GitHub, Linear, Notion. The visual app is no longer the cheapest way to reach a service — it's just the one we're used to.
Agents read better than they click. That single fact changes what the interface to your digital life should look like.
Some teams are betting on agents that watch your screen and click for you. It sounds general. It is — and it's expensive, fragile, and concedes your data to whoever runs the model.
We don't yet know how to make those systems scale, and we don't know how to make them safe. Maybe one day. Not today.
Keep one place — a markdown vault on your machine. Let the agent talk to your tools through MCP. Let it maintain the vault like a wiki, not a dump. Surface what needs you.
You read it. You talk to it. It acts. Your data stays on your disk. The compute stays small because the agent reads the right thing, not everything.
A companion that knows you, lives on your machine, talks to every service you use, and can rewrite parts of itself when your life changes. Self-evolving, local, yours.
We're not there. We're shipping toward it — one integration, one daily note, one action at a time. brain² today is the first surface of that buddy. Everything we build is in service of it.
Notion AI. Glean. ChatGPT connectors. The AI lives inside one app, sees that app's slice, and your data sits on their servers.
Useful inside that vendor's box. Invisible to the other nine.
Rewind, Limitless, CUA-style agents. They record what you do and click for you.
General-sounding, but compute-heavy, fragile, and they ship your screen out to the model.
Markdown vault on your machine. MCP to reach every service. A daily note as the first surface. A buddy you can talk to instead of ten apps you click through.
Local-first by design, not by marketing.
