# How to Build a Mood Watchlist with ChatGPT

ChatGPT works well when the mood watchlist needs to be summarized into a friendly recommendation you can share or act on immediately. Run `blend_taste`, then ask ChatGPT for a top-one recommendation with a brief reason.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT.
2. Name two or three reference films and describe the mood you want to match.
3. Run `similar-movies.blend_taste` and inspect the ranked shortlist.
4. Ask ChatGPT to pick the single best match for tonight and explain why it fits the mood.
5. Add the pick to your queue or search for it on your preferred streaming service.

## Example Prompt

```
I want something cerebral and slow-burn. Use similar-movies to blend Prisoners and Zodiac, exclude Se7en, and recommend the single best watch for tonight with a one-sentence reason.
```

## Tips

- A single top recommendation with a clear reason is often more useful than a ranked list.
- Use ChatGPT to translate mood vocabulary into a concrete pick.
- Exclude titles you have already seen to keep the shortlist fresh.
