Control data flow, model access, and workspace policy.
Manifesto
Overlay exists because the best models, tools, files, and workflows should meet in one open interface that people and institutions can actually control.
Principles
Control data flow, model access, and workspace policy.
Inspect, self-host, extend, and adapt the interface.
Route work by quality, speed, cost, and governance.
Files, notes, memory, and tools stay attached to work.
The interface closest to your work should respect where that work lives.
Teams should be able to inspect, self-host, extend, and change the system they depend on.
Model choice, data flow, and workflow policy should be configurable, not dictated by one vendor.
The product should feel like a tool you use every day, not a maze of disconnected AI accounts.
