Show HN: Ketchup AI – Free AI image generator, no signup required

Hi HN,

  I built Ketchup AI, a free AI image generator that works without any signup or
  registration.

  Key features:
  - No account needed - just open and start creating
  - Completely free with no usage limits
  - Built-in AI prompt optimizer that helps beginners write better prompts
  - Supports multiple languages (English, Japanese, Korean, etc.)
  - Images aren't stored on our servers (privacy-first)
  - Local prompt history (last 20, stored in browser only)
  - Multiple aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4

  Average generation time is around 30 seconds. The prompt optimizer is particularly
   useful - it automatically expands simple descriptions into detailed prompts,
  which significantly improves output quality.

  Tech stack: Next.js 15, React, TailwindCSS, deployed on Cloudflare.

  I wanted to make AI image generation accessible to everyone without the friction
  of signup walls or credit systems. Would love to hear your feedback!
