TechCrunch catalogs notable AI products and startups that have shut down or missed expectations, from OpenAI's failed super-app redesign to hardware flops like the Humane AI Pin. The pattern shows that even major tech companies struggle to sustain standalone AI products when larger platforms absorb similar features into their core offerings.

• About 42% of corporate AI initiatives get abandoned due to insufficient funding, technical challenges, competition, or weak user demand
• Major platforms like OpenAI, Google, and Microsoft are consolidating AI features into existing products, making it harder for standalone AI startups to survive (Relay, Notion Mail, Huxe all shut down as competitors integrated similar tools)
• AI hardware bets like Humane AI Pin ($230M raised, sold for $116M to HP) and Rabbit R1 launched with hype but failed due to unreliable performance and limited usefulness
