If you cannot find your desired website across listed tabs in the KeepStreams application, it is recommended to enter the website URL directly into the built-in browser on the Home page of KeepStreams.

Here are the detailed steps to follow, using Bilibili as an example:

1. Download and install KeepStreams on your Windows or macOS computer.

2. Open KeepStreams and enter bilibili.com into the built-in browser to access the Bilibili website.

3. Log into your Bilibili account and browse the Bilibili library for the video you want to download.

4. Play the video, and you will see an analyzing button in the upper left corner of the built-in browser.

5. Wait a few seconds for the analysis to complete, and then you will see the download page where you can choose output settings as you like.

6. Click on the Download Now button to start downloading your desired Bilibili video immediately.

7. You can monitor the download process in the Downloading tab or check the downloaded video in the Downloaded tab.
