The "Silo" Problem

AI models are brilliant, but they are isolated islands. Your chat history with Claude doesn't exist to ChatGPT. When you hit a limit or need a second opinion, you lose everything.

❌ Without Contusk

  • Manually copying 10 files
  • Losing variable names
  • "Sorry, I don't know what you discussed before"

✅ With Contusk

  • One-click context injection
  • Continuous workflow
  • "I see you were working on X..."

Frequently Asked Questions

Is my data sent to the cloud?

No. Contusk runs a local ChromaDB server on your machine. Your chat context stays on `localhost` until you explicitly paste it into an AI window.

Which browsers are supported?

Any Chromium-based browser: Google Chrome, Arc, Brave, Edge, and Opera.

Does it work with customized GPTs?

Yes. Contusk reads the DOM of the chat window, so it works with standard chats, Custom GPTs, and Projects.
