404Tomb vs Kidgeni

404Tomb is a digital graveyard that memorializes defunct internet products, discontinued software, and dead AI tools. It catalogs over 1,000 deceased products with tombstone pages recording what each one was, when it lived, and when it shut down.

Browse by category spanning AI chatbots, generative art tools, productivity apps, and hundreds of other tags. The dedicated AI Graveyard section focuses specifically on failed AI products. You can search the cemetery, visit a random tombstone, or submit your own memorial for a product that has passed on.

The site supports English and Chinese, and was featured on Product Hunt. It is part memorial archive, part cautionary museum of the internet's constant churn of startups and side projects.

Kidgeni is a fun AI playground where kids turn ideas into art, animated doodles, bedtime stories, and printable books. The homepage splits the product into Create, Doodle, and Stories modes, plus coloring pages and merch printing on shirts, hoodies, and long sleeves. New accounts get 15 free credits to start generating before choosing a paid plan.

Most kid-facing AI tools focus on chat or homework help. Kidgeni leans into hands-on creation: sketch a doodle and watch it transform, write a short prompt and get a story you can publish, or send a design to print on wearable merch. The Education plan even bundles classroom access for up to 30 students, which sets it apart from single-family art apps.

Parents, teachers, and young creators who want a guided space to experiment with art and storytelling without opening a general-purpose chatbot will find Kidgeni built for that job. It is less about coding lessons and more about letting kids make things they can hold, wear, or read aloud.
