A growing list of dead AI products shows that building something cool and building something that survives are two very different jobs.
TechCrunch has been keeping a running tally of AI startups and products that shut down, got sold off, or quietly pivoted away from their original promise, and the list keeps getting longer. First published on September 15, 2026 and updated again on October 24, 2026, the AI graveyard now includes Relay, Humane's AI Pin, Character.ai, Notion Mail and several other names that once looked like the future of the industry.

How Relay became the newest name in the AI graveyard
Relay was a five-year-old workflow automation company that let people run email and task automation through AI agents, basically trying to be an AI-powered Zapier. It shut down completely in August 2026. The reason was not that the product failed to work. It was that OpenAI, Google and other giant platforms started building the exact same kind of automation directly into tools people already use every day.
TechCrunch described the problem simply: Relay lost its reason to exist as a stand-alone product. That is the core tension running through the entire AI graveyard list. A small company proves an idea works, and then a much bigger company with far more users and far more cash just builds the same feature into something customers already have open on their screen.

Character.ai shows that popularity does not guarantee survival
Character.ai looked like one of the biggest consumer AI success stories around. Founded in 2021 by former Google researchers Noam Shazeer and Daniel De Freitas, the app let users chat with customizable bots built around fictional characters, celebrities and fan creations. It raised $150 million in 2023 at a $1 billion valuation, a number that made it one of the hottest AI startups anywhere.
Then in 2024, Google reportedly paid $2.7 billion to license Character.ai's technology and bring Shazeer and De Freitas back in-house, while the startup kept running without its founders. Reporting now places a bankruptcy filing roughly five years after the company launched. The company's technology turned out to be worth billions to Google, even as the independent business it came from could not hold together on its own.
Notion Mail and Huxe fell to changing habits, not just competitors
Notion Mail launched in April 2025 as an AI tool meant to organize inboxes and handle routine email work automatically. It did not die because a bigger company copied it. Notion found that users were increasingly turning to separate AI agents to manage their email instead of relying on the built-in tool. The shutdown was scheduled for September 22, 2026, making it a rare case where shifting user behavior, not direct competition, sealed a product's fate.
Huxe, built by former developers of Google's NotebookLM, turned written content into podcast-style audio. It shut down in May 2026 after larger platforms rolled out similar audio features to audiences that already numbered in the millions. Figgs AI followed a different but related path. The character creation platform drew more than a million users between 2023 and 2024, yet its own developers said keeping the service free had simply become too expensive to sustain.
Humane's AI Pin turned hardware ambition into a cautionary tale
Humane raised $230 million to build the AI Pin, a wearable meant to replace parts of how people use smartphones. The device struggled with basic performance from early reviews onward, and the trouble did not stop there. Humane later warned customers to stop using its charging case entirely because of a possible battery-fire risk, a serious safety issue layered on top of an already shaky product.
Humane shut down the AI Pin business in February 2025. HP stepped in and acquired most of the company's assets for $116 million. The episode made clear that AI hardware carries every normal risk of electronics and manufacturing, on top of whatever risk comes from the AI model itself. Microsoft's Recall feature, announced at Build 2024 to capture screenshots as a kind of photographic memory for your PC, ran into its own wall of privacy and security criticism that forced major delays and kept the feature under scrutiny long after launch.
The pattern behind every entry in the AI graveyard
Look across the whole list and a few repeating problems show up again and again. Big platforms like OpenAI, Google and Microsoft can absorb a smaller company's best feature and ship it to millions of existing users overnight. Running AI models, especially for video, audio or constant background agents, costs real money, and free products built on that cost structure tend to collapse once investor subsidies run dry. Hardware adds its own layer of risk, since a wearable or device has to work as reliably as any other gadget on the market. And sometimes a founder's technology becomes valuable to a giant company even while the original startup falls apart financially, as Character.ai's story shows.
TechCrunch has said the graveyard list will keep growing as more AI products close, get sold or quietly change direction. The lesson emerging from every entry so far is that flashy demos and fast user growth do not guarantee a company survives. What matters longer term is distribution nobody can easily copy, costs that make sense without a subsidy, and habits users actually stick with once the novelty fades.
