AI tools die fast — and rumours die slower. This archive lists only tools whose shutdown or rename we can prove with a linked source. No proof, no entry.
Rule of this page: every entry below has a linked source — a reputable news outlet or an official announcement. If we could not prove a shutdown, the tool is not listed here.
Screenless AI wearable. HP bought Humane's software and patents; servers went off on 28 Feb 2025, so calling, messaging and AI queries stopped working.
Read the proof →Microsoft ended support for Cortana in Windows as a standalone app in August 2023 and pointed users to Copilot and Bing Chat instead.
Try the successor →OpenAI closed the plugins beta: no new plugin chats from 19 Mar 2024, existing plugin chats ended 9 Apr 2024. Custom GPTs replaced them.
Try ChatGPT →Bard was not killed as a product, it was renamed: Google announced on 8 Feb 2024 that Bard would now be called Gemini.
Try Gemini →Microsoft announced on 15 Nov 2023 that Bing Chat and Bing Chat Enterprise would simply become Microsoft Copilot.
Try Copilot →Science LLM demo launched 15 Nov 2022 and taken down after about three days, after it produced fabricated citations and nonsense papers.
Read the proof →Twitter chatbot launched in March 2016 and shut down within about a day after users steered it into posting offensive tweets; Microsoft apologised publicly.
Read the proof →The 2021 Codex models (code-davinci, code-cushman) were discontinued on 23 Mar 2023; OpenAI told developers to move to GPT-3.5 Turbo. Note: the 2025 Codex agent is a different, newer product that reuses the name.
Read the proof →A note on renames: Bard and Bing Chat are listed because those names were discontinued, even though the products live on under new names. That distinction matters before you mourn a tool.
A tool, name, or API that the maker stopped supporting or renamed, backed by a linked news or official source on this page.
Because the old name is gone. Bard and Bing Chat are listed as retired names, with their successors linked, so nobody confuses a rename with a shutdown.
Yes — use our contact page and include a link to the shutdown announcement. Entries without proof are not added.
