thumbishTurn a video script into a thumbnail concept
Upload a PDF, DOCX, TXT or Markdown script to Thumbish. Use the story, audience and key reveal to develop a thumbnail concept before generating artwork.
Thumbish accepts a video brief and script attachments so the thumbnail conversation can use more context than a short image prompt. Upload a supported script, identify the intended audience and develop a visual concept that reflects the actual video.
Give the agent the context that matters
A script contains details that a topic alone can miss: the opening question, the evidence, a change in perspective and the final takeaway. Highlight the part that should drive the thumbnail rather than assuming every scene deserves equal attention.
Include the viewer you want to reach, the main promise and any constraints. Mention a required face or product reference, words that must not appear and facts that should not be exaggerated. Your brief helps separate the central story from background detail.
Supported script files and upload limits
The studio accepts PDF, DOCX, TXT and MD script files up to 100 KB. Free, Lite and Mega allow one script attachment per message. Image references are separate attachments with plan-specific limits.
Use a text-based script. If text cannot be extracted from a scanned or image-only document, export a text version or paste a concise brief. Do not assume that every visual element in a document will become part of the creative context.
Review the interpretation before the image
In Design mode, inspect the proposed concept and approve the direction before artwork generation. Check the title, visual subject, composition and optional headline. A concept that sounds interesting but misrepresents the video needs correction before it becomes an image.
On paid plans, use Plan mode when the title and hook are still unsettled. Keep the thumbnail and opening promise aligned so a viewer is not led into a different story from the one the video tells.
Give precise feedback
Describe what is wrong and what must remain. If the subject is correct but too small, request a composition change. If the concept focuses on a minor scene, point back to the central promise in the script. This helps keep revisions tied to a concrete decision.
Generation and revisions consume credits. Review the concept carefully, then inspect the final artwork for text and visual inaccuracies. The script gives context, but it does not guarantee that every generated detail is correct.
Frequently asked questions
Does uploading a script automatically create an image?
No. The script adds context to the conversation. You still review the proposed direction and approve generation.
Can I upload a Google Docs link?
There is no native Google Docs connection. Export the script to a supported file format and attach that file.
