#Create a thumbnail

  1. Prompt — written for your video: the writing AI reads the niche, title and script and writes the image prompt for this video's subject and niche; the page names the niche and angle it wrote for. Edit it as you like. When the production has a visual style, the prompt leaves the art style to it.
  2. Text on the thumbnail — a short hook written for this video (2–5 words that make people curious, shocked or amazed — never the title). Click one of the other ideas, press New ideas, or write your own; Use title is still there. The image model designs the lettering.
  3. Pick up to six scene images as references.
  4. Optional: add an example thumbnail (upload an image or paste a YouTube link) and choose what to use it for.
  5. Choose how many versions and generate.

#Pick the final thumbnail

In Thumbnails select the one you want; it is used in YouTube Details and Final Review. Regenerate makes a new take of one version; Delete removes it. When Pipeline makes the thumbnail and none is chosen yet, it selects the finished one itself (it no longer makes a new thumbnail on every pass).

Reference images are sent in the way each provider supports (Gemini, OpenAI and Together AI). A model that cannot take references says so instead of silently ignoring them.
