SeiSei AI

SeiSei AI (Videm) is a free AI image generator you can start using without signing up. Put your idea into a prompt and generate AI illustrations or realistic-style photos to quickly visualize a concept—perfect for trying different looks before you commit.

You can generate images from text prompts and also upload reference images to guide the output. The workflow is built for iteration: generate a first version, then adjust details like lighting, composition, color, and background density to move the result closer to your goal. Use it for character concepts, product-style visuals, blog/SNS thumbnails, campaign graphics, and other creative drafts.

If you need motion, the platform also supports creating short AI videos and can include audio as part of the video experience. Choose the appropriate model and output settings when you want more control, and keep generating until the direction feels right.

Free usage includes a limited anonymous allowance (1 day up to 2 images). For continued use, SeiSei AI offers credit-based plans with selectable models and monthly credit amounts, such as Basic (¥3,000/month), Pro (¥6,000/month), and Max (¥30,000/month).
