TechCrunch published a running list of dead AI products on September 15 with the shutdown reasons stated plainly. Notion Mail closes September 22 because users preferred separate AI agents for email over an integrated one; ChatGPT Atlas was folded back into the main ChatGPT product on August 9; Relay died in August after OpenAI and Google built its automation directly into their own tools; Sora shut in March over operating costs and retention. The pattern is worth more than the individual entries — the failure mode for an AI feature attached to an existing SaaS product is being absorbed upward by a model provider, not being out-competed sideways.
