MAYBE
A strong concept riding a wave, but monetization must be invented.
What is Second Brain for AI v2?
Second Brain for AI v2 is an open-source, self-hosted memory layer that lets users store context once and recall it across Claude, ChatGPT, Cursor, and any MCP-compatible client. By running in the user’s own Cloudflare account, it promises data ownership and cross-platform persistence. The project has gained early traction (555 stars, Product Hunt #3) but has no visible revenue model. It's an opinionated piece of infrastructure for the emerging 'AI memory' category, solving a real problem for power users who juggle multiple AI tools.
