LLM Memory

Every AI conversation starts from zero. Your projects, decisions, and preferences disappear as soon as you close the chat. Second Brain fixes that. It is a self-hosted memory layer that works with Claude, ChatGPT, Cursor, and any MCP client. You can store context once and recall it by meaning instead of keywords. It includes duplicate detection, semantic search, and a web UI. Built on Cloudflare, it offers a free tier and your data remains yours. MIT licensed.

What breaks your AI workflow between sessions?

I built Second Brain because I kept hitting the same wall.

I'd have a really productive session with Claude, talk through an architecture decision, get to a clear conclusion, close the tab. Next day I'd open a new chat and have to explain everything from scratch. Same thing with Cursor. Same thing with ChatGPT. Every tool starts fresh, every time.

Hey Product Hunt, I'm Rahil. I built Second Brain.

I got tired of explaining myself to every AI tool during each session. A new Claude window is a blank slate. A new Cursor project doesn’t know my stack. It adds up quickly.

Second Brain is a self-hosted memory layer that connects to Claude, ChatGPT, Cursor, and any MCP client. You store context once and recall it by meaning across any session. Everything lives in your own Cloudflare account, not on a third-party server. There's a free tier, and you don't need a subscription. You also get a web UI to browse and manage everything visually.

What makes it different:

It works with all your AI tools—not tied to one app.

It uses semantic recall, which finds memories by meaning instead of exact keywords.

It’s self-hosted, so your data stays in your own Cloudflare account.

There’s a free tier, so it costs nothing to run.

The web interface lets you browse, search, and manage memories visually.

II’m really curious: what context do you find yourself re-entering most? That has influenced my roadmap more than anything else.

Ask me anything. Big shout out to @fmerian for his support!
