Why I built Second Brain

Every AI conversation starts from zero. You re-explain your projects, your preferences, your history -- every single time. That bothered me enough to fix it.

Second Brain is an open source, self-hosted memory layer that sits across Claude, ChatGPT, Cursor, Windsurf, and any MCP-compatible tool. One memory store. Every interface. Your context travels with you.

It runs entirely on Cloudflare Workers + D1 + Vectorize -- no servers, no subscriptions, no vendor lock-in. You own your data.

What your sponsorship supports

• Keeping the core library free and open source forever
• Building the hosted version for people who want one-click setup
• Shipping the knowledge graph layer (v2) that links memories relationally
• Writing docs, tutorials, and guides so anyone can deploy in under 10 minutes

Even a small sponsorship signals that this work is worth continuing. It means a lot.
