SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Creating a high-CTR YouTube thumbnail requires design decisions about composition, contrast, and text placement that many creators struggle with. This Skill plans the thumbnail composition, generates a 16:9 image through the muapi CLI, and provides concrete text overlay guidance.

Core Features & Use Cases

  • Composition Planning: Reasons about emotion-first framing, contrast, and rule-of-thirds layout before generating the image.
  • Image Generation: Calls muapi image generate with the gpt-image-2-text-to-image model at 16:9 aspect ratio, styled to the channel's brand.
  • Text Overlay Guidance: Returns suggested 3-5 word overlay text, placement on the canvas, and font style recommendations for post-production tools like Canva or Photoshop.
  • Use Case: A creator making a video titled "I tried 7 AI tools in 24 hours" provides the title and channel style, and receives a generated thumbnail image plus overlay text and placement suggestions.

Quick Start

Ask the agent to design a YouTube thumbnail for your video title, optionally describing your channel style and the subject to feature.

Frequently Asked Questions about muapi-youtube-thumbnail

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a YouTube thumbnail with AI?▼

Provide your video title, an optional channel style, and an optional subject description. The skill plans the composition, then calls muapi image generate with the gpt-image-2-text-to-image model at 16:9 aspect ratio to produce the thumbnail.

What inputs does the YouTube thumbnail generator need?▼

The only required input is the video title or topic. You can optionally supply a channel style such as dark moody gaming or bright educational, and a subject description such as a surprised young man in a hoodie.

Can I use my own face photo in the generated thumbnail?▼

Yes. If you already have a channel image or face photo in the session, the skill uses muapi image edit to incorporate it into the generated thumbnail instead of creating a subject from scratch.

Why doesn't the thumbnail include the title text directly?▼

Text rendering in image generation models is unreliable, so the skill keeps text out of the prompt. It instead returns suggested overlay text, placement, and font recommendations for you to add in Canva or Photoshop.

What do I need to configure before generating thumbnails?▼

You need the muapi CLI installed and a MUAPI_API_KEY configured via muapi auth configure. For models without a CLI alias, the skill falls back to calling the MuAPI REST endpoint directly with curl.
