Persistent memory for Claude, ChatGPT & Cursor. Free.

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.
Does it work seamlessly with ChatGPT and Claude together?

@nithin_raju1 Yes! Claude and ChatGPT both connect via MCP and pull from the same Second Brain memory layer. Store something in Claude, recall it in ChatGPT. Same context, same session history, across both.
That's actually one of the core reasons I built it... your memory shouldn't be locked to one tool.

Quick update since launch. Here are a few things worth noting:
We shipped the Second Brain CLI today. If you use the terminal, you can now capture and recall memories without leaving it.
For those asking about integrations, Second Brain works with Claude, ChatGPT, Cursor, Windsurf, and any MCP-compatible client. There’s also an Obsidian plugin in the community directory, a Chrome extension, iOS Shortcuts in the repo, and a web UI if you prefer managing everything visually.
CLI, Obsidian, Chrome extension, iOS Shortcuts, MCP… same memory, every interface.

Really appreciate the mention, Rahil. Glad that feedback was useful.
What I like about the roadmap direction is that “memory” stops being a bucket of notes and starts becoming a set of commitments with status. That matters a lot once people use it for product, writing, or strategy work, because the cost of a stale-but-confident memory is higher than just forgetting.
Excited to see where you take the status/source layer.

@dobaduc appreciate you Duc! Are you building anything that deals with AI context or memory?
