thron-memory

One private memory for all your AI apps.

Tell ChatGPT something on your phone. Claude, Gemini or Cursor knows it on your laptop an hour later. You never repeat yourself again.

Works with ChatGPT, Claude, Gemini CLI, Cursor, VS Code, Windsurf, Codex, Claude Code and any other app that supports MCP.

What is MCP? It's the standard plug that lets AI apps use outside tools. If an app's settings mention Connectors, Integrations, Tools or MCP servers, your memory works there.

• Private. Your memory lives in your own account or on your own computer. There is no company in the middle, not even us.

• Free. No subscription. Runs on Cloudflare's free plan, or on your computer.

• Yours. Your memory is a set of plain notes you can read, download and keep.

• Careful. It refuses to save passwords or keys, and it never deletes: when something changes, the old version is kept.

Set it up (about 5 minutes, no coding)

Pick the one that fits you:

Option 1: Everywhere (phone and computer)

This gives your memory its own small, private home in a free Cloudflare account. Cloudflare is a large internet company; this uses their free plan and needs no credit card.

1. Click this button:

   

2. Sign in to Cloudflare, or create a free account. If it asks you to connect GitHub, create a free GitHub account too (it keeps your copy of the code).

3. When you see MEMORY_PASSWORD, make up a password and write it down.

4. Click Create and deploy. Wait about a minute.

5. Click the web address it shows you (it ends in workers.dev). That page is your memory's home. Bookmark it.

6. Type your password. Click Copy link.

7. The page shows you exactly where to paste the link for Claude, ChatGPT and other apps. Do it once per app.

Done. Try it: tell one app "Remember that my favorite color is green," then ask a different app or your phone "What's my favorite color?"

Come back to your memory's home anytime to connect another app or download a copy of everything it remembers.

Option 2: Claude Desktop only

Nothing to sign up for. Your memory stays on this computer.

1. Download thron-memory.mcpb.

2. Double-click it. Claude Desktop opens. Click Install.

Done. Your memory is saved as notes in a folder called thron-memory in your home folder.

Option 3: Coding agents

Paste this into Claude Code, Codex, Gemini CLI, Cursor or any agent that can run commands:

Install thron-memory for me: run `npx -y thron-memory setup` and tell me what it printed.

It connects every coding app it finds: Claude Code, Codex, Gemini CLI, Cursor, VS Code, Windsurf and Claude Desktop. It needs Node.js 18 or newer.

Want the same memory on your phone too? Paste this next. It moves your memory into your own free Cloudflare account and keeps everything you already saved:

Set up thron-memory for my phone: run `npx -y thron-memory cloud`. If a Cloudflare sign-in page opens, I'll sign in.

A small window then shows your private link and where to paste it.

Make it even smoother (optional)

The skill is a short set of instructions that helps Claude and ChatGPT decide when to check and update your memory.

• Claude: download thron-memory-skill.zip, then go to Customize > Skills > Upload.

• ChatGPT (plans with Skills): Skills > Create > Upload from your computer, same file.

Apps without skills still work. Your memory tells every app how to use it as soon as it connects.

What your memory looks like

Your memory is a set of short pages, one per person, project or topic:

## Current
- Prefers afternoon meetings (2026-11-13, chat)

## History
- [2026-11-13] was: Prefers morning meetings (2026-10-02, email)

Two pages are special:

• core: your rules for every AI app. Ask any app to change it, for example "Add a rule to my memory: never save anything about my health."

• inbox: notes the app wasn't sure where to put. Apps tidy it up later.

Privacy

Good to know:

• Your private link is the key. Treat it like a password. Paste it only into app settings, never into a chat.

• AI apps see what they read. When ChatGPT or Claude reads a page, that text goes to them like anything else you type. Keep truly secret things out of memory.

• Extra privacy for Option 1: after setup, delete the MEMORY_PASSWORD secret in Cloudflare (your memory's home page shows where). Your password still opens your memory's home, and Cloudflare no longer holds anything that can unlock your memory.

• Option 3 with cloud is the strictest cloud setup: your private link is made on your computer and Cloudflare only ever sees a fingerprint of it.

• Your memory's pages are decrypted only briefly, inside your own Cloudflare account, while an app is using them.

• No tracking, no analytics, nothing sent to us. The code is small so anyone can check it (src/).

Questions

Does it cost anything? No. Cloudflare's free plan covers it easily, and it sleeps when nobody is using it.

Which apps work? Any app that can add an MCP server or "custom connector": ChatGPT (developer mode, on plans that have it), Claude (web, desktop and phone), Gemini CLI, Cursor, VS Code, Windsurf, Codex, Claude Code, and more every month.

I forgot my password. Open your memory's home and click I forgot my password. You can start over with a new one, but that erases the memory, because it was locked with the old password. Download a copy now and then.

Can I see or edit my memory myself? Yes. Option 1: click Download a copy of my memory on your memory's home. Options 2 and 3: open the thron-memory folder in your home folder with any text editor or Obsidian.

How do I remove it? Remove the connector from each app. Option 1: delete the thron-memory Worker in your Cloudflare dashboard. Option 2: uninstall the extension in Claude Desktop's settings. Option 3: run claude mcp remove thron-memory -s user (and the same for other apps), then delete the .thron-memory folder.

For developers

Commands (Option 3):

npx -y thron-memory setup    # memory folder + connect coding apps on this computer
npx -y thron-memory cloud    # move memory to your Cloudflare account, for phone and web apps
npx -y thron-memory url      # show your private link (to you, never to an agent)
npx -y thron-memory backup   # copy cloud memory into ~/thron-memory
npx -y thron-memory status   # where memory lives

Tools the server gives every app:

Connect any MCP client by hand. Remote (Streamable HTTP): use your private link, or https://<your-worker>.workers.dev/mcp with the header Authorization: Bearer <token>. Local (stdio), after running setup once:

{ "mcpServers": { "thron-memory": { "command": "node", "args": ["/Users/you/.thron-memory/app/bin/cli.js"] } } }

How it's built. Under 1,500 lines of plain JavaScript, zero dependencies.

• src/memory.js: the memory and its six tools.

• src/mcp.js: the MCP protocol.

• src/local.js: the file store.

• src/worker.js: the encrypted Cloudflare store. It uses AES-256-GCM with HKDF-derived keys, and page names are hidden with HMAC.

• src/page.js: your memory's home page.

• bin/cli.js: the commands.

• desktop/manifest.json: the Claude Desktop extension.

Run npm test. Run node scripts/build.mjs to build the release downloads. Run python assets/make_visuals.py to rebuild the images; they use the ThronOS mark and its Saira and Fira Mono fonts, which are under the SIL Open Font License (assets/fonts).

Part of ThronOS

thron-memory is one small part of ThronOS, the larger internal system I built to run my own agents across my computers and phone. ThronOS also handles to-dos, scheduling, jobs that run across machines, devices and voice; it stays private. This repo opens up just its memory, so anyone can give their AI apps one memory they own.

The ideas carry over directly:

• Every fact lives on one page.

• Changes keep their history.

• Conflicts are flagged for you instead of guessed.

• Agents write as they work, without being asked.
