Trillion vs ChatGPT for decisions

• Capability

  Decisions

• Product

  ChatGPT

• In short

  Asking ChatGPT gives an answer in a chat. Trillion walks the decision step by step, keeps its reasons, and asks later how it turned out.

• What Trillion does

  Your AI works through a hard choice with you one question at a time: what should change, what you already know, the options, what to delete and simplify, and how you will know it worked. Trillion keeps the decision with its reasons, next action and success measure, lets you record how it turned out, and on the paid plan shows how people in similar situations decided, without naming anyone.

• What they do

  - A useful response, including a decision note, can be saved to a project. - Project instructions apply only inside that project. - Memory can carry context forward between chats.

• What they do that Trillion does not

  - General-purpose: the same chat can also search the web, run deep research or generate images while you decide. - No setup needed; available on a free plan.
