Mem0 Chrome Extension Alternative (2026) — AI Memory is the Last One Standing
The Mem0 Chrome extension was officially archived on May 30, 2026. Rethread.ai shut down. AI Memory (aimemory.pro) is now the only surviving cross-platform AI memory Chrome extension.Here's what happened and why it matters.
⚠️ Mem0 Chrome Extension: Archived
The official GitHub repository (mem0ai/mem0-chrome-extension) now shows:
"This project has been archived. mem0-chrome-extension is no longer actively maintained and this repository is now a public archive. Thank you to the 600+ stargazers, 97 forkers, and every contributor."
Impact: The largest open-source cross-platform AI memory Chrome extension (⭐675 stars) is gone. Mem0 has shifted focus to their Cloud Platform + SDK for enterprise developers.
⚠️ Rethread.ai: Domain Expired
Rethread.ai, previously a direct competitor, now shows a GoDaddy domain parking page. The domain is for sale. This browser extension-based AI memory tool has completely ceased operations.

Why Did Mem0 Archive Their Chrome Extension?
Mem0 (formerly Mem0ai) raised $24M in funding and has 58K+ GitHub stars for their core memory platform. Their strategic shift from browser extension to Cloud Platform + SDK makes business sense:
- Enterprise focus: Mem0 is targeting developers building memory-powered applications, not end users managing their own conversations.
- API/SDK revenue: B2B API pricing is more sustainable than consumer browser extension monetization.
- Maintenance burden: Browser extensions require constant updates as AI platforms change their DOM structures — a resource-intensive task with limited ROI.
This creates a unique opportunity: AI Memory is now the only mature cross-platform AI memory browser extension in the market.
Ready to Switch from Mem0?
AI Memory is free to start. Install the Chrome extension, import your conversations, and never lose an AI conversation again.
