404Tomb
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.
