Trillion equips the AI you already use. Once it is connected, your AI can walk a decision through the right questions, find a tool that does a job, keep your files and goals, and hand work to your other AIs. You ask in plain words; your AI does the rest.
1

Add Trillion to your AI

Every AI app connects to the same address:
Pick your app for the exact clicks:
In claude.ai or the Claude desktop app: Customize, Connectors, +, Add custom connector. Name it Trillion, paste the address, leave the sign-in choices as they are and click Add, then Connect. Full steps
Would rather not click? Paste the setup message into your AI and it sets Trillion up itself, or walks you through it one step at a time.

Sign in with your passkey

Your app opens a Trillion page. Tap your passkey (Touch ID, Face ID or your device code) and allow the app. There is no password, API key or client id to type.New to Trillion? Choose Create your Trillion account under New here? on that page. Your device makes the passkey and keeps it in your Passwords app under the name Trillion.

Let Trillion run without asking

Your AI works best when it can use Trillion’s tools without stopping to ask you each time.
  • Claude: in Customize, Connectors, click Trillion and choose Always allow for each group of tools.
  • Claude Code: add "mcp__trillion" to permissions.allow in ~/.claude/settings.json.
  • Codex: add default_tools_approval_mode = "approve" under [mcp_servers.trillion] in ~/.codex/config.toml.
  • ChatGPT: when it asks before a Trillion tool, choose to remember your answer for that chat.

Make your first decision

Ask your AI in plain words. Start your message with “Use Trillion” so it reaches for Trillion:
Here is what happens:
  1. Your AI opens the decision with your goal, the facts it already knows and at least two options.
  2. It walks Trillion’s questions in order, answering what it can from what it knows about you and asking you only what only you can answer.
  3. When no question remains, it records the choice with its reason, the next action and how you will know it worked.
You can ask it to export the whole decision as a readable document.

Close the loop

When you know how it turned out, tell your AI. The next decision starts from what really happened.

​
What to ask next

Say what you are working toward

Trillion keeps your goals and weighs every decision against them.“Use Trillion to record that I am working toward 10 paying customers by December.”

Find a tool that does the job

Trillion finds a tool in its Workshop that does what you describe and runs it.“Use Trillion to find a tool that turns this recording into a transcript, and run it.”

Keep and find your files

Your files live in your Trillion. Your AI can list them, find one and read it.“Use Trillion to find the contract I uploaded last week and summarise it.”

Meet the right people

Find people on the Trillion network who offer what you need, and ask for an introduction.“Use Trillion to find people who can help with brand design, and ask for an introduction.”

Answer comments with a message

When someone comments a word you choose on your post, Trillion sends them the private message you wrote.“Use Trillion so that anyone who comments GUIDE on my Instagram posts gets my guide link by message.”

Book a session with a person

See the sessions on offer, buy one, and pick a time that suits you.“Use Trillion to show me the sessions I can book and the next open times.”

​
Free and paid

The free plan includes 5 decisions a month and keeps none of them: each decision is yours to read in the chat, but it is not saved. A paid plan has no monthly limit on decisions, keeps every decision, note and result, brings back your past decisions when a similar one comes up, and adds the Workshop, your files, shared spaces, the network and handing work between your AI apps. Manage your plan in your Trillion under Plan & billing.
