Show HN: Ketchup AI – Free AI image generator, no signup required (ketchup-ai.com)

Ketchup AI is a newly posted free AI image generator that lets anyone create images from text without signup, usage limits, or watermarks. It claims to run on “advanced AI image generation models” trained on large image datasets and offers features aimed at nontechnical users: a built-in prompt optimization engine that expands simple descriptions into professional-grade prompts, multilingual input (Chinese, English, Japanese, Korean, etc.), multiple aspect ratios (1:1, 16:9, 9:16, 4:3, 3:4), real-time progress feedback and an average generation time of ~30 seconds. The app emphasizes privacy — saying generated images aren’t saved on servers — and provides a one-click workflow to generate and download images immediately. For the AI/ML community this matters as another effort to democratize image synthesis by removing friction (no registration, no fees, no watermark) and adding usability features like automated prompt engineering and fast inference. Key technical implications include reliance on a high-performance inference engine and prompt-expansion tooling to raise output quality for beginners. Important caveats: the underlying model, training data, and governance/moderation policies are not specified, so questions remain about copyright, dataset bias, content safety, and the sustainability of offering unconstrained free generation. Ketchup AI is notable for UX-focused access, but practitioners will watch for transparency and responsible-use safeguards.
