Thumbish uses your video hook and audience context to develop a clear visual story, topic-specific typography, expressions and optional headline. Review the concept and its reason to watch before generating. The aim is an attention-grabbing thumbnail that delivers the video’s promise; actual click-through rate depends on your audience and needs measurement.
Thumbish brings the video brief, script, channel persona and reference images into a conversational thumbnail workflow. You review a proposed concept before generating artwork, then request revisions in the same conversation. Choose Flash or Aura and set image quality before approving generation.
Thumbish works as a virtual thumbnail design assistant: describe your video, audience and constraints, then review a concept covering the subject, composition and headline before generating. You can refine the direction in conversation. It is an AI tool, so you remain responsible for checking the creative decisions and final artwork.
Yes. Choose one source in Reference thumbnails: My channel continues the styling, typography, effects and composition patterns of your own examples; Competitors uses each example as inspiration for an original design. Upload images or add thumbnails from YouTube video links, then press Save references. Free supports two references; Lite and Mega support five.
Yes. Request a focused edit to a thumbnail generated in Thumbish in the same conversation. A revision edits the existing artwork rather than starting concept planning again. It uses Flash Medium and costs 10 credits, even if the original was generated with Aura.
Flash is the faster image model, available on every plan. Aura is the quality-focused model on paid plans. Free includes Low and Medium quality; paid plans include Low, Medium and High. Flash costs 10, 20 and 30 credits per image at Low, Medium and High; Aura costs 20, 30 and 40.
Yes. Add a face image to your Channel Persona in the studio sidebar. Thumbish uses it as a reference for that channel. AI-generated likeness can vary, so review the face and details before publishing.
Yes. Attach a PDF, DOCX, TXT or MD script in the studio composer. Thumbish uses the script as context for your concept and artwork. Check the studio guide for upload limits and provide a text-based file if a scanned document has no extractable text.

No. Thumbish helps you develop and generate thumbnail artwork; it does not guarantee views or a click-through rate. Video performance also depends on the title, audience, topic and video itself. Use YouTube Analytics and supported YouTube testing tools to evaluate actual results.
