Nexus is a desktop application that brings your notes, a real web browser, and an AI assistant into one local-first workspace. This repository is the public documentation for Nexus — it does not contain the application's source code, which is proprietary. See the Nexus Proprietary License for terms of use.

Nexus replaces three separate apps — a notes app, a browser, and an AI chat client — with one window where they actually talk to each other. Open a page in the built-in browser, ask the Assistant a question, and it already has context on both what you're reading and what you've written. Everything is stored locally in a SQLite database on your own machine; nothing is synced to a server Nexus operates, because there isn't one.
At a glance:
| Notes | Markdown-based, with folders, tags, [[wiki links]], automatic backlinks, version history, and a knowledge graph |
| Browser | A real multi-tab browser built into the app — bookmarks, downloads, and per-tab isolated sessions |
| Assistant | An AI chat that can search your notes semantically and read your open browser tabs, using your own API key |
| Storage | 100% local SQLite — export to Markdown or PDF, or back up/restore the whole database anytime |
Nexus is built on Tauri and ships as a native desktop application for Windows, macOS, and Linux.
