Trillion gives your AI a set of questions to walk through, in order, before it recommends a choice. On a paid plan every run is saved to your account, and you can read or share it as a document. On the free plan nothing is kept.
Customize → Connectors → Add → Add custom connector. Name it Trillion and use https://work.gettrillion.ai/mcp. Claude signs you in with a passkey the first time.

Add https://work.gettrillion.ai/mcp as a connector. Apps that support sign-in (OAuth, with dynamic client registration) open a passkey sign-in and need no key.
Create your account at https://work.gettrillion.ai/account with a passkey. Your key appears there once; paste it where the app asks for an API key, or send it as a Bearer token to https://work.gettrillion.ai/mcp.
Use Trillion to decide what to cook tonight. I have 25 minutes and some leftover rice.
Use Trillion to decide whether to fix the checkout bug or ship the new pricing page first, then export the decision.
Show me my earlier Trillion decisions that look like this one, and how they turned out.
Tell Trillion that last week's dinner decision worked: it took 18 minutes.
One general method plus versions for cooking, relationships, software and tennis.
Opens a decision with your options and evidence, answers each question in order, and records the choice with its reason and next step.
Saves notes to a decision at any time.
On the paid plan, shows your earlier decisions like this one and, if others share theirs, how people decided in similar situations.
Saves what happened afterwards, in your words.
Returns the whole run as a readable document or as data.
The free plan gives a set number of decisions each month and keeps none of them. A paid plan keeps every decision and what you are working toward, and lets your AI read your past decisions and show similar ones.
