Installation, Compatibility & Usage Instructions

Nex AI Knowledge Copilot is built exclusively for the Google Chrome browser and works on Windows, macOS, Linux, as well as Chrome OS. The extension also functions on Chromium‑based browsers such as Microsoft Edge and Brave, though the official store listing is under Chrome.

Step‑by‑Step Installation

1. Open the Chrome Web Store and search for “Nex AI Knowledge Copilot.”
2. Click the Add to Chrome button and confirm the permissions request. The extension will appear as a small blue icon next to the address bar.
3. Once installed, click the icon to open the onboarding wizard. You’ll be guided through a brief tutorial that explains how to enable the YouTube and Article modules.
4. Optionally, sign in with a Google account to sync your Idea Archive across devices. This step is optional and does not affect the core summarization capabilities.

How to Use YouTube Copilot

Navigate to any YouTube video you want to study. After the page loads, click the Nex icon. The extension will automatically generate a summary panel on the right side of the video. You can:

• Read the bullet‑point summary to grasp the main concepts.
• Click on timestamps to jump directly to the relevant part of the video.
• Save any line as an idea card by clicking the “Save” button next to the bullet.

How to Use Article Copilot

When you land on a long article or blog post, click the Nex icon. The tool scans the page and presents a clean, scroll‑free summary at the top of the screen. You can:

• Toggle between a short “high‑level” view and a detailed “deep‑dive” view.
• Highlight any sentence to add it to your Idea Archive.
• Export the full summary as a .txt or .pdf file for offline reading.

Both modules work instantly after the initial analysis, typically within a few seconds, even on lengthy content. The extension also respects site permissions, ensuring it never interferes with sites that block third‑party scripts.

Frequently Asked Questions

Is Nex AI Knowledge Copilot really free?

Yes, the Chrome extension is completely free. There are no hidden subscription fees or premium tiers at this time. All core features, including YouTube Copilot, Article Copilot, and the Idea Archive, are available to every user.

Does the extension collect my personal data?
