# Similar Thumbnails

Find YouTube thumbnails that are visually similar to any reference video. Research design patterns, study what styles perform well in your niche, and get creative inspiration — all through natural language prompts in your AI assistant.

## Prerequisites

- **Connected AI assistant** — Claude, ChatGPT, or any other supported platform
- **Active NexLev account** — [Connect to your AI assistant](/docs/mcp/quickstart) to get started. [Upgrade to Pro](?required_nexlev_lite_pro_access=true) for higher quota limits.

## Basic Usage

Provide a video ID and ask for similar thumbnails:

```
Find similar thumbnails to xILOssyMh1k
```

The video ID is the part after `?v=` in a YouTube URL (e.g. `youtube.com/watch?v=xILOssyMh1k`).

## What it Returns

Per result:

- Thumbnail image preview
- Video title, channel name, view count, upload date, duration
- Similarity score (0.0 – 1.0, higher = more similar)
- Direct link to the YouTube video

**Similarity score guide:**

| Score        | Meaning                    |
| ------------ | -------------------------- |
| 0.25 – 0.30+ | Near-identical composition |
| 0.20 – 0.25  | Strong visual correlation  |
| 0.15 – 0.20  | Moderate similarity        |
| 0.10 – 0.15  | Some shared elements       |

## Troubleshooting

- **No results** — Verify the video ID (11 characters, exact copy). Very new videos (<24 hrs) may not be indexed yet. Try a more popular reference video.
- **Low similarity scores** — A unique thumbnail design can actually be a competitive advantage. Low scores suggest original positioning.
- **Results don't match expectations** — The algorithm matches visual composition, not topic. Add a category filter in your prompt to narrow results.
- **Quota limit reached** — If you've hit your daily limit, [Upgrade to Pro](?required_nexlev_lite_pro_access=true) for higher quota limits.
