AI tools die constantly — taking paid subscriptions, your data, and sometimes a $700 device with them. Unlike "AI graveyard" lists, this tracker focuses on what matters if you're affected: refund eligibility, data-export deadlines, and what to do next. Every entry is verified against the linked source before publishing.
OpenAI deprecated the Assistants API (announced August 26, 2025); endpoints stop working entirely on August 26, 2026.
What to do: Developers: migrate to the Responses API + Conversations API before the cutoff — OpenAI provides a migration guide (Assistants → Prompts, Threads → Conversations, Runs → Responses) but no automated tool.
After shutting the Sora app and web experience on April 26, 2026, OpenAI is discontinuing the Sora API on September 24, 2026.
What to do: API users: migrate video workloads before September 24, 2026. The in-app content export window closed with the April 26 app shutdown.
OpenAI announced on March 24, 2026 it was discontinuing Sora; the app and web experience shut down April 26, 2026. No official reason was given.
What affected users could do: Users were directed to export content via the in-app sunset flow before the shutdown; purchased credits remain usable for Codex. Refunds follow the standard ChatGPT subscription refund process.
Google discontinued the standalone Whisk image tool on April 30, 2026, merging its capabilities into Flow. Media left in Whisk libraries after that date was permanently deleted.
What affected users could do: Users had to download images or use the opt-in migration to Flow before April 30, 2026 (assets did not transfer automatically). Existing AI credits carried over; regions without Flow lost access entirely.
Meta acquired Limitless (Pendant wearable + Rewind Mac app) on December 5, 2025. Pendant sales ended; Rewind screen/audio capture was disabled from December 19, 2025. Service was discontinued in Brazil, China, the EU, Israel, South Korea, Turkey and the UK.
What affected users could do: Users in the seven discontinued regions had until December 19, 2025 to export transcripts and data before permanent deletion. Existing Pendant customers were moved to a free plan with support promised for at least a year. No refund terms were documented.
Co-founder Joe Braidwood shut down the AI therapy app Yara, concluding that AI chatbots become dangerous — "Not just inadequate. Dangerous." — when someone in crisis reaches out.
What affected users could do: The product was free and its planned subscription never launched, so no refunds applied. A rare case of a founder closing a working product over safety.
The Microsoft-backed app-development startup (≈$445M raised, once valued at $1.5B) entered insolvency on May 20, 2025 after a lender seized $37M, and filed Chapter 7 bankruptcy in Delaware in early June 2025. Press investigations reported its AI capabilities were overstated, with much of the work done manually.
What affected users could do: No customer refund or data-export process was ever documented — a reminder to check the company behind a tool before committing business-critical work to it.
Humane announced on February 18, 2025 that AI Pins would stop connecting to its servers ten days later — ending calls, messaging and AI features — as HP acquired its staff, IP and software platform for $116M (not the device business).
What affected users could do: Refunds only for purchases still inside the 90-day return window, with requests due February 27, 2025 — earlier buyers of the $699 device got nothing. Owners had until February 28 to export photos and data before permanent deletion.
Embodied, maker of the $799 cloud-dependent Moxie companion robot for children, announced in early December 2024 it was shutting down after a funding round collapsed, warning robots would stop working once its servers went offline.
What affected users could do: The company said it could not issue refunds (it would only "prioritize" refunds for purchases within 30 days if its assets were sold). A community effort — the open-source OpenMoxie local server — later let owners keep basic functionality.
Policy and pricing changes (short of a shutdown) are tracked separately on our policy-change alerts.
