When your AI is connected to Trillion, it gets a set of tools. You never call them by name: you ask in plain words, like "Use Trillion to help me decide what to focus on this week", and your AI picks the tools that do it. These pages list every tool, grouped by the job a person does, with what it does, what it takes, and an example of what your AI sends. Start Trillion with a new person and keep what they are working toward. Walk a decision through its questions, record the choice, and learn from how it turned out. Keep conversations word for word so every AI you use can read them, and see what your AIs did. Find a tool that does the job, run it, build your own and offer it to others. Get a job done in several checked steps, and keep your own step-by-step methods. Make Trillion run a tool or workflow by itself when something happens or at a set time. Save, find, read and show your files, and find moments in your recordings. Let the AIs you use find each other and hand work on, on your account or inside a shared space. Work with other people in a group, project or event: invite them, share into it, and decide who may do what. Choose who sees each thing you keep, where the things you send to Trillion go, and read what others shared with you. Find people on the Trillion network who offer what you need, and ask to meet them. Join a community, post, go to events, take courses and meet other members. See the sessions you can book with a person, pay, pick a time, and move or cancel it. Write in your own formats, and keep private answers to the questions your audience asks. ## How the tools work * **One address, every AI.** Every AI app reaches the same tools at `https://app.gettrillion.ai/mcp`, and every AI signed in to your account reads and writes the same Trillion. What you start in one AI, another can pick up. * **Signed in as you.** Your AI signs in with your passkey once. It only ever reaches your own Trillion and the spaces you are in. * **Reads only, or changes things.** Each tool is marked so your AI app knows which ones only read and which change something. Apps that ask before a tool runs use this to decide what to ask about. * **Safe to send twice.** Tools that start something take a `request_key` or `source_id`: sending the same one again returns what was already started instead of doing it twice. * **Some tools come with a paid plan.** The free plan includes 5 decisions a month and keeps none of them. A paid plan keeps every decision, note and result, and adds the Workshop, files, shared spaces, the network, handing work between your AIs, and fast picks with `score_candidates`. Communities and connecting any AI app come with every account. ## Every tool | Tool | What it does | Page | Effect | | - | - | - | - | | [`start_setup`](/reference/setup-and-goals) | Start Trillion
