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.

Cloudflare WorkersYour site. Our network.
5.0 (68 reviews)
Workers gave us edge-native compute with built-in KV and Vectorize — everything Second Brain needs (semantic search, memory storage, the knowledge graph) in one platform, no stitching together separate services. Deploying the entire backend as a single Worker kept it simple for users and for us.

VS CodeMicrosoft Visual Studio Code lets you build and debug apps

I used VS Code as my main IDE. Cursor is built on top of VS Code, so the two work together. I relied on Cursor for AI-assisted coding, but the main editor, keybindings, extensions, and configuration are all from VS Code. I tried Antigravity, but it felt too early; the developer experience wasn’t there yet. I stick with VS Code because its ecosystem is unmatched: the extension library, terminal integration, and the fact that every tool I use has a VS Code integration first.

Cloudflare's free tier is genuinely free — no credit card, no surprise bills. Every Second Brain user gets their own Worker, KV store, and Vectorize index running at the edge, globally, without paying a cent. No other platform comes close to that at zero cost.
