One Brain. Everywhere you work. One memory for Claude, ChatGPT, Cursor and every AI tool you use. Runs in your own Cloudflare account. Open source.

You use AI every day. A year of it should add up to something, and right now it doesn't. Every new chat starts from zero.

Second Brain is a memory layer that runs in your own Cloudflare account. Claude, ChatGPT, Cursor, Windsurf and any other MCP client read and write the same store, so what you work out in one tool is there in the next one.

Getting things in

  • Connect what you already use: Obsidian, Notion (email and calendar ship with 2.1)
  • Save in the moment: Chrome extension, iOS Shortcuts, CLI, REST /capture
  • Or just let the assistant store things as you talk, which is how most of it happens

Getting things back

Recall is semantic, not keyword. Memories link to each other, so a multi-hop search surfaces the reasoning behind a decision, not just the decision.

Entries carry a status (canonical, draft, deprecated) so an agent knows which version of a fact to trust.

Contradictions get flagged for a human to settle instead of quietly overwritten.

Where it lives

Your Cloudflare account: Workers, D1 and Vectorize.

Typical personal use sits inside Cloudflare's free tier. Open source on GitHub. No account with us, and nothing routes through our infrastructure.

Setup

Signed desktop app for Mac and Windows, one-click Cloudflare deploy, or clone the repo and run wrangler.

Questions & Answers

As answered by people managing phpBB and TheSecondBrain.dev.

What makes your product unique?

TheSecondBrain.dev's answer:

Most AI memory tools store your context on their servers. This one deploys into your own Cloudflare account, so the memory is yours in a literal sense: your database, your vectors, your billing. We can't read it because we never have it.

The other difference is recall:

  • Semantic, not keyword. Ask by meaning, not by remembering what you called it.
  • Multi-hop. Memories link to each other, so a query surfaces the reasoning behind a decision, not just the decision.
  • Status-aware. Entries are marked canonical, draft or deprecated, so an agent knows which version of a fact to trust.
  • Honest about conflicts. When two memories disagree it flags it for you instead of quietly picking a winner.

Why should a person choose your product over its competitors?

TheSecondBrain.dev's answer:

It works everywhere you work. Claude, ChatGPT, Cursor, Windsurf, Codex, any MCP client. Most memory tools only remember what happened inside their own app, so you end up with three AI tools holding three different versions of you.

You own the deployment. One-click deploy to Cloudflare, or a signed desktop installer if you'd rather not touch a terminal. Typical personal use sits inside Cloudflare's free tier, so there's no subscription to cancel and no vendor to migrate off later.

It's open source. MIT licensed. Read the code, fork it, extend it. Nothing about how your memory is stored or retrieved is a black box.

How would you describe the primary audience of your product?

TheSecondBrain.dev's answer:

People who already live in these tools. They have an Obsidian vault or a Notion workspace, they're in Claude or ChatGPT every day, and some of them are in Cursor too. They're not casual users and they're not necessarily developers. They've built a system, and they've noticed the system doesn't talk to itself.

The shared frustration isn't "AI forgets." It's that a year of real thinking, hours of working through actual problems, hasn't left anything behind. Every conversation is good and then it's gone, and a month later they're figuring out the same thing from scratch.

They also tend to care where their work sits. Not privacy absolutists, just people who'd rather their own thinking accumulate in an account they control than in someone else's product they might have to leave.

What's the story behind your product?

TheSecondBrain.dev's answer:

I was using Claude, ChatGPT and Cursor every day and re-explaining the same projects to each of them. A year of that adds up to nothing. The decisions I'd worked out in one tool simply didn't exist in the next one.

I built it for myself first, on Cloudflare because I already had an account and the free tier meant I could run it without thinking about cost. Then I open sourced it, and what people asked for shaped what it became. The desktop app exists because a user on Product Hunt asked for a path that didn't involve a terminal, and she was right to ask.

I still use it every day. Most of the roadmap comes from hitting the limits of my own memory layer.

Which are the primary technologies used for building your product?

TheSecondBrain.dev's answer:

  • Cloudflare Workers โ€” runtime
  • Cloudflare D1 โ€” SQLite, entries and relationship graph
  • Cloudflare Vectorize โ€” embeddings and semantic recall
  • Workers AI โ€” embedding generation and synthesis
  • TypeScript
  • Model Context Protocol (MCP) โ€” client integrations
  • Tauri โ€” Mac and Windows desktop app
  • Wrangler + GitHub Actions โ€” deploy and release

Who are some of the biggest customers of your product?

TheSecondBrain.dev's answer:

  • People who run Obsidian, Notion and several AI tools side by side
  • Consultants, operators and independent professionals who think out loud with AI all day
  • Writers, researchers and strategists whose best thinking currently lives in chat logs they can't search
