OCNO: Private AI Browser Brain

About

OCNO turns your browser into a private AI workspace.

Most browser AI extensions are cloud chatbots in a sidebar. To understand your data (pages, documents, prompts, and browsing context), they have to send that context outside your browser.

OCNO is different.

It is built for people who want powerful AI assistance in the browser without trading privacy for convenience.

OCNO helps your browser remember, understand, and connect your work over time — locally and privately.

WHY OCNO

Install OCNO if your browser has become the place where you read, research, compare, write, and make decisions — but your tabs, history, documents, and ideas still feel disconnected.

OCNO turns scattered tabs, pages, documents, and ideas into private, searchable, connected memory.

WHAT OCNO HELPS YOU DO

• Understand any page
Ask questions, summarize, explain, clarify, or translate directly on the page you are reading.

• Remember what you read
Recover pages, topics, and ideas from your browsing history without digging through endless links.

• Reconnect your research
OCNO links your current page with related pages, documents, and topics you explored before.

• Build your OCNO Brain
Turn scattered tabs and browsing history into a visual knowledge graph of connected ideas.

• Discover better sources
Get relevant articles and updates based on your real interests, not generic engagement algorithms.

• Chat with your own files
Upload PDFs, Markdown files, DOCX files, notes, papers, documentation, and reports — then ask questions across them.

• Write faster
Turn bullet points into emails, drafts, summaries, reports, replies, or translated text.

• Complete web tasks faster
Ask what to do next on a page and get guided actions inside the interface.
