In your AI assistant
datrix in your AI assistant
The same two jobs — create a matrix, work with a matrix — done from your own assistant (Claude, ChatGPT, or Antigravity). The built-in assistant is the quickest way to start; this is the more flexible and powerful way to work, with all of your assistant's reasoning brought to your decisions.
Do the one-time Connect below, then either path works.
One time
Connect your assistant
Links an outside assistant to your datrix account so it can actually build and save matrices.
Until you connect, your assistant can talk about a decision but can't create or save anything in datrix — you'd just be having an ordinary chat. Connecting is the step that turns the conversation into a real, saved matrix.
The plugin bundles both halves — the decision-capture Skill and the connection to your datrix account. In Claude Code, one install wires up everything; in the Claude app (claude.ai and Cowork), install the plugin, then click Install once more on its bundled connector. Either way you sign in to datrix once, and you're connected from then on.
In a Claude Code CLI session, run:
/plugin marketplace add lockstride/dmatrix-extensions/plugin install dmatrix@dmatrix-extensions/reload-pluginsThat's it — start a new conversation and Claude offers to capture decisions. Prefer a menu? Run /plugin and browse the Discover tab.
In the Claude app (paid plans), install the same plugin from the menus — no terminal:
- Open Customize → Plugins from the left sidebar.
- Click Add → Add marketplace → Add from a repository.
- Paste this repository URL, then add it — Claude syncs the marketplace for you:
https://github.com/lockstride/dmatrix-extensions - Once it's added, open the Personal tab to see the available plugins.
- Find the datrix Decision Capture card, click Install, and accept the trust prompt.
- Last, connect the plugin to datrix: open the installed plugin, switch to its Connectors tab, click Install next to dmatrix, and sign in when prompted.
That final Connectors-tab step is the one people miss — without it, Claude reports the datrix tools aren't reachable. Installed once, the plugin works in both chat and Cowork. On Team and Enterprise plans, an Owner enables Skills and Cowork for the org first.
On the Free plan, or prefer manual setup?
Full setup details
OpenAI 
Antigravity How to know it worked
- 1The plugin is installed. In Claude Code, run /plugin — datrix should appear in the list as installed and enabled. In the Claude app, it's listed under Customize → Plugins — and its Connectors tab should show the dmatrix connector installed too. That second install is the step people miss.
- 2Your account is connected. You sign in to datrix once. In the Claude app, that happens right after you install the plugin's connector. In Claude Code, it happens on first use — run /decide (or /mcp → dmatrix → Authenticate) and complete the browser approval.
- 3Confirm and manage it. After you've signed in, your assistant shows up in datrix under Settings → Connected Clients — the same place you go to disconnect it later. Give it a moment; the list refreshes on its own.
Not seeing it? If datrix isn't listed, re-run the install for your surface above. If the plugin is installed but Claude says the datrix tools aren't reachable, install its connector (Claude app: the plugin's Connectors tab → Install). If it's connected but nothing's saving, finish sign-in — run /decide and complete the browser approval.
Once connected, both paths below work — and mix freely with anything you do inside datrix.
Create
Create a matrix — from a conversation
The same job as Create a matrix, started from your chat instead of the datrix screen.
- Starttype /decide — or just ask in plain words. Your assistant also offers on its own when it notices you weighing options.
- Describe / shapeanswer as it draws out your options, criteria, and scores.
- Savethe finished matrix saves straight to your datrix account.
This isn't only for decisions you're making right now. Scroll back to something you talked through earlier — yesterday, last week, anywhere in the thread — and run /decide to turn that past conversation into a matrix in one step. No copy-paste, no starting over. It's one of the fastest ways to get a real, structured decision out of a chat you've already had.
Work with
Work with a matrix — from your assistant
The same job as Work with your matrix, run from your assistant with the full matrix in context.
- Openpoint your assistant at a matrix you already have; its full context — options, criteria, priorities, scores, rationale — becomes live in the conversation.
- Ask for a changetalk through trade-offs, ask questions, draft a recommendation, or have it update the matrix. Every change lands back in datrix.
keep both windows open side by side and watch your assistant build and manipulate your matrix in real time inside the datrix interface.
