Discover learning videos by topic, select numbered recommendations, and turn Bilibili and YouTube videos into transcripts, abstracts, and study notes using the Hermes host model.

## Good to know before installing

Intercepts gateway messages with a Bilibili/YouTube URL, a "by2kb <topic>" prefix, or (for 1 h after a recommendation list, same user/chat) a bare number reply, and runs the separately installed by2kb CLI (BY2KB_COMMAND or PATH), which searches Bilibili/YouTube, downloads media and runs ASR; enrichment prompts go to your active Hermes model.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install by2kb
```

2. Said no? Turn it on later:

```bash
hermes plugins enable by2kb
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
