Our tool empowers you to design eye-catching thumbnails with customizable typography, stickers, badges, shape overlays, and preset aspect ratios. For standard design workflows—including template selection, layering text, positioning stickers, and uploading your own local background photos—all canvas rendering runs directly inside your browser without uploading your image assets to ImageFlow application servers. For users who wish to explore automated ideas, our optional AI Generator tab allows you to enter a topic prompt, which communicates with Google Gemini to suggest title layouts and fetches generated background visuals. This hybrid approach gives you complete control: fast, private in-browser design for your personal assets, with optional cloud AI intelligence when you want creative inspiration.
