Your guide to Thumbish Studio

1. Sign in and open a channel

A channel keeps your creative conversations, persona and thumbnail references together. It does not connect to your YouTube account. Free supports one channel, Lite two, Mega five and Enterprise unlimited channels.

2. Give the agent useful context

Describe your audience, the promise of the video and the subject the thumbnail should show. The agent develops the creative direction from your brief, script, persona and references. Ask for help with the title or hook in the same conversation.

Attach a PDF, DOCX, TXT or MD script through the plus menu, up to 100 KB. Free, Lite and Mega support one script per message. Image attachments must be no larger than 2 MB each. Free allows one image per message; Lite and Mega allow three. A channel can save a persona and style references: two references on Free, five on Lite or Mega.

3. Choose Flash or Aura

Open the model and quality control in the input box. Flash is the faster image model and is available on every plan. Aura is the quality-focused image model, available on Lite, Mega and Enterprise.

Free starts with Flash; paid plans start with Aura. If you choose a different model, your choice stays saved for that account on the same browser or app installation until you change it. Both models cost the same at each image quality.

4. Set your image quality

Use the quality slider to choose Low, Medium, High or Max. Medium is selected by default. Free includes Low and Medium; paid plans include all four qualities. Aura is locked on Free, regardless of quality.

The selected quality and cost appear before approval. Changing your selection affects the next generation; an image already in progress keeps the model and quality it started with.

5. Review, generate and revise

Check the proposed subject, composition, headline and reference style before approving. The agent uses your references to guide typography, color, lighting and effects while adapting the design to your new topic. Ask for changes if the direction misses your story.

After generation, inspect text, faces and product details. Request revisions in the conversation. If a result is delayed, check its status before starting another generation.

6. Download and publish

Download the generated image. Thumbish requests 1280 × 720 artwork. Check the file in the thumbnail preview tool, then follow the YouTube upload workflow.

Plan credits

Free includes 50 starting credits. Lite includes 1,050 monthly credits; Mega includes 4,100. Enterprise includes custom credit quotas. These are the amounts added when a purchase or renewal is credited.

Lite supports approximately 50 thumbnails and Mega approximately 200 at Medium quality, counting image generation only. Chat, concept work, revisions and higher image qualities reduce the available thumbnail count.

Other credit costs

Concept creation costs 10 credits, concept revision 5 and a chat reply 2. These share your balance with image generation and revisions. See pricing or use the credit calculator to estimate your workflow.

Practical troubleshooting

• For an oversized attachment, reduce the file size before attaching it again.
• For a scanned script, export a text-based file or paste a concise brief.
• If an option is locked, review the available models and qualities for your plan.
• If the image misses the story or channel style, revise the concept and clarify which reference details matter.
• For a connection error, check your internet and the generation status before retrying.
