Ask pages, recall research, connect ideas, discover what matters, and write with context - privately and locally. OCNO turns your browser into a private, local AI workspace.
Most browser AI extensions are cloud chatbots placed in a sidebar. To understand your pages, documents, prompts, and browsing context, they send that information outside your browser.
OCNO is different.
It is built for people who want powerful AI assistance without trading privacy, control, or intellectual freedom for convenience. OCNO helps your browser understand what you open, remember what you read, reconnect ideas, discover useful sources, and support your writing over time, locally and privately.
WHY OCNO Install OCNO if your browser is where you read, research, compare, think, write, and make decisions, but your tabs, history, documents, and ideas still feel disconnected. OCNO turns scattered pages, files, research, and unfinished thoughts into a private, searchable, connected workspace.
