Second Brain for AI v2: self-hosted persistent memory for Claude, ChatGPT, and Cursor

Second Brain for AI v2

Second Brain for AI v2 adds a self-hosted memory layer to Claude, ChatGPT, and Cursor so conversations don't start from scratch every time. It runs in your own Cloudflare account, free tier available, MIT licensed. V2 automatically links related memories, follows those links during recall, and separates settled decisions from drafts. It hit 374 upvotes and #4 of the day on Product Hunt. The post doesn't disclose latency, storage caps, or concurrency limits—those are the numbers I'd check before relying on it.

Why it matters: MIT license, free tier, and MCP client support give it real footing among memory-layer tools. But a Product Hunt launch isn't hard news, and the v2 improvements are only described in the summary with no benchmarks or user numbers, so it lands at the 72 featured threshold.
