That reader may be a model. We design for relevant results, usable context and sources your application can follow.
COMPANY / OUR REASON TO BUILDThe World Engine
The World Engine
for AGI.
Intelligence needs a connection to the world.
We’re here to build it.
01 / THE MISSIONThe world moves.
Our first step: Web Search API
The world moves.
AI should move with it.
A model’s knowledge is a starting point. The world is what happens next.
New research. A changed product. A question nobody thought to ask before. Useful intelligence needs a way to find information beyond what it already knows.
We’re building that connection. The World Engine for AGI is our ambition: make the world’s information accessible to the systems that need to understand it.

MODEL THINKING × INFORMATION RETRIEVAL
We understand what AI and LLMs need after a search: relevant context, traceable sources and a response that fits into the next step of reasoning.
Team backgrounds, not company affiliations or endorsements.
03 / HOW WE BUILDBig ambition.
Big ambition.
Focused work.
Access is part of the product.
Every supported Web Search feature belongs in the Free Plan. Developers should spend their energy building, not choosing paid add-ons.
Search is where we start.
Our ambition is broad. Our focus today is precise: a Web Search API that belongs in an agent’s everyday toolkit.
