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.
WHAT OCNO HELPS YOU DO
Ask questions, summarize, explain, clarify, or translate directly on the page without repeatedly copying context into another tool.
Search your browsing memory by meaning and recover pages, sources, topics, and ideas without remembering exact titles or URLs.
Surface related pages and previous research while you browse, keeping today’s work connected to what you already learned.
Turn browsing history, documents, and research into a visual knowledge graph of connected topics, sources, and ideas.
Get a personalized feed of relevant articles and updates, ranked around your interests instead of generic engagement signals.
Ask questions and explore ideas through local AI models while keeping your prompts and working context on your device.
Add PDFs, Markdown files, DOCX files, notes, papers, documentation, and reports to private document vaults, then ask questions across them.
Draft, rewrite, expand, summarize, translate, and refine text while your research and browser context remain close.
Use compatible local models for sensitive, controversial, unconventional, or unfinished questions without a cloud chatbot mediating the conversation.
Ask what to do next on a page and receive practical guidance directly inside the interface.
Manage your local models, browsing memory, document vaults, and AI workflows from one private browser workspace.
