YouTube Thumbnail Design: Gemini Nano Banana & Canva

About this course

Design a thumbnail that makes a clear, accurate promise

Explore an AI-assisted YouTube thumbnail workflow using recorded Google Gemini/Nano Banana, ChatGPT, and Canva examples. Learn to connect a video’s actual content with an intended viewer, a clear subject, readable text, and a coherent visual direction.

This course focuses on creative examples and a repeatable review process. A strong-looking thumbnail does not guarantee viral reach, a particular click-through rate, views, revenue, or channel growth. The aim is to create a useful concept, inspect the result, and learn from appropriate feedback.

Important note about recorded tools

The course includes a recorded Sora example. Sora is discontinued: OpenAI ended its web and app experiences on April 26, 2026 and its API on September 24, 2026. Treat that lesson as a historical demonstration of creative direction. The new quizzes, role-plays, PDF resources, and final project can be completed with a written brief or sketch without Sora access. Other product features, accounts, and interfaces may differ from the recordings; check current official information before paying for or relying on a tool.
