Most AI tools live in a browser tab, disconnected from the files, apps, and context that make up your actual work. Crux is different. It is an AI personal assistant that runs on your desktop, understands your workflow, and keeps your data local to you.

Why we built Crux

We wanted an assistant that is genuinely personal. One that:

  • Works across your desktop, files, and apps, not just a chat box.
  • Keeps your chats, files, and context local, so your data stays yours.
  • Meets you where you already are, including Telegram, WhatsApp, and Discord.

Three ways to use Crux

Crux adapts to how you work, with three modes:

  1. Desktop App Mode. A full workspace for deep, multi-step tasks.
  2. Overlay Mode. Summon Crux over any app, without breaking your focus.
  3. Live Assist Mode. Real-time help while you work.

Works with everything

Crux connects to the tools you already use, including Gmail, Notion, Google Sheets, Docs, Drive, Calendar, and GitHub, so it can actually do things instead of just talking about them.
