The AI Tool Graveyard
Every tool on CurataHub is reviewed while it's live — but some don't stay that way. They get acquired, pivot to a different product, or quietly drop the plan that made them worth recommending. If you're evaluating a tool today, knowing what happened to similar ones is part of doing your homework.
Every entry below is confirmed directly from the tool's own site — a shutdown notice, a domain redirect, an acquisition announcement, or a pricing page with the relevant tier removed — not a third-party rumor.
Respell
Self-serve AI agent/workflow builder
Respell was acquired by Salesforce; its team joined Salesforce to build Agentforce. The standalone Respell product was shut down, with existing customers directed to migrate to Lindy.

MultiOn
AI agent-building platform / browser automation agent
multion.ai/pricing now 301-redirects to theagi.company. The company pivoted entirely to 'AGI, Inc.,' building AGI-0, an on-device consumer action agent for phones and computers, rather than continuing as an agent-building SaaS platform. The developer platform is now request-only ('Get access').
When: Confirmed pivoted as of August 2026 via live redirect

Superagent
Open-source AI agent framework
The original open-source AI agent framework rebranded into an AI/agent security company, now positioned as 'Security for AI-native developers' offering code scanning, runtime guardrails and red-teaming — no longer an agent-building platform.

CrewAI
Self-serve AI agent orchestration platform
CrewAI's hosted platform previously offered a self-serve 'Professional' tier (approximately $25/month) from around October 2025 through spring 2026. That tier was removed in spring 2026; the hosted platform currently offers only a Free tier (50 executions, 1 seat) and a custom-quote Enterprise tier, with no public self-serve paid option.
When: Self-serve Professional tier available roughly October 2025 - spring 2026; removed spring 2026

Frequently asked questions
How do you decide a tool belongs on this page?
Only tools with a verifiable status change go here — a shutdown notice on the tool's own site, a domain redirect to a different product, an acquisition announcement, or a pricing page that has visibly dropped the tier that made it relevant. We don't list a tool here on a rumor or a third-party aggregator's say-so.
Does a tool being listed here mean it was bad?
No. Most of these shut down or pivoted for reasons that have nothing to do with product quality — an acquisition, a business-model change, or a team moving on to a different problem. This page exists to save you time if you're evaluating a tool today and want to know what happened to similar ones, not to judge anyone.
How often is this page updated?
There's no fixed schedule. Entries get added when we come across a verifiable status change while researching a CurataHub category, and each entry shows the date it was last confirmed.
