Who this is for and what it does

Auturis is a system for someone who already thinks seriously about their own choices and who has a problem against which they would like to test that thinking. Auturis will help you think through problems that fall under two broad questions: “What should I do?” and “What is right?” For any circumstance, the system is designed to help you answer these two questions.

In order to be able to perform this task more effectively than a “chatbot,” Auturis requires that you first build your personal or organizational knowledge graph, which is a task with which it will assist you.

The structured nature of the knowledge graph provides Auturis with its distinctive advantage. Standard chatbots will, if you grant permission, make use of your personal information. But this information exists, figuratively speaking, in a pile, which the AI must sift through in an attempt to determine the relevance of some piece of that pile to the current conversation. The graph in the Auturis system, by contrast, exists as a structured network of meaning. This map, which the AI accesses, but which remains on your computer, helps the AI identify the relevance of your personal goals to the situation at hand.

The knowledge graph also provides the Auturis system with the capacity to determine the degree to which a proposed new action will fit within your, or within your organization's, existing system of ends (or values). This metric is then used, together with the information in your graph, to evaluate your proposed courses of action. In the case of small groups or organizations, the same graph structure is used to measure the degree to which a policy hinders individuals or stakeholders in the achievement of their stated aims. The data provided by this analysis can be used to assess the fairness (or rightfulness) of any proposed or existing policy. These matters are explained in greater detail on the page for each question: What should I do? and What is right?

You may find what Auturis has to say to be truly informative, or it may just tell you something that you already knew, in which case, you will have further support for your decision.

Auturis' Graph

Auturis works by leveraging a knowledge graph that you build yourself.

The graph takes the shape of a tree. The roots and boughs of this tree correspond to essential human ends and domains of practice, which appear in the list below. You supply the branches and the leaves. The branches represent your intermediate level goals, such as financial independence, and the leaves represent the concrete actions that are required to pursue them, such as opening a bank account.

The eight roots — terminal human ends — and the bough, or domain of practice, through which each is pursued:

These are fixed — the system doesn't rename, add to, or remove them. Whatever you build, and whatever you later test, is checked against this same structure, not against a mood or a house style.

Start by talking to Auturis

The first tab you land on, once your key is set up, is a conversation. Auturis greets you and asks what's on your mind. You can ask how the system works or talk through whatever you are currently facing. If you have already built your graph, then Auturis will utilize that information in its discussions with you.

It can also act directly from the conversation. It can run a test on a maxim or a proposed rule, or add to your graph. It keeps its own conversation history and can use search when that's actually useful to what you're asking.

Auturis in the classroom

Auturis also works as a classroom tool, not just an organizational one. Two ready-to-run lesson plans apply the same hindrance-check and personal-coherence machinery to a real ELA / U.S. History unit — one testing a proposed courtroom rule against a play's own stakeholders, the other adding each character's own moral dilemma on top of it — backed by a reliability check run before either was written. Neither has been taught to a real class yet, and both pages say so plainly.

Get access

Auturis is in beta. Read the beta-tester agreement, agree to it, and your download is on the next page.

Available for Windows, Mac (Apple Silicon), and Mac (Intel).

Getting started

Your OS will warn you the first time you try to open this app — that's expected, not a sign anything's wrong. Auturis is a beta from an independent developer. It isn't distributed through the App Store or Microsoft Store, and it isn't signed with Apple's or Microsoft's paid developer certificates. Those cost money every year, and I'd rather spend it once there's evidence people want the app. Until then, your computer can't tell who made it, so it errs on the side of caution. Find the section below for what you downloaded; the steps take under a minute.

Windows

1. Right-click the downloaded zip and choose Extract All — don't just double-click to open it, since Windows lets you browse inside a zip without actually extracting it, and the app won't run correctly from there. If you double-click Auturis.exe without extracting first, Windows will warn "this application may depend on other compressed files in this folder" — that's the sign to go back and extract properly. Once it's extracted to a real folder, run Auturis.exe from inside it, keeping it together with the _internal folder next to it.
2. Windows will likely show a blue "Windows protected your PC" SmartScreen warning. Click More info, then Run anyway.

Mac (Apple Silicon)

1. Unzip and drag Auturis.app out of the unzipped folder.
2. Your Mac will refuse to open it and will very likely only give you the option to put it in the Trash. In order to open it, follow these steps:
   1. Open Terminal (a built-in Mac app, not something you need to install): press Command (⌘) and Space together, a search box will pop up, type Terminal, then press Return. A window with plain text will open — that's normal, it's just how Terminal looks.
   2. Select and copy the line below (click into it, then Command+C):
      xattr -cr ~/Downloads/Auturis.app
      click into the Terminal window, paste it in (Command+V), and press Return. (If you moved the app somewhere other than the Downloads folder, replace ~/Downloads/ with the folder you moved it to.)
      What this does: when you download a file, your Mac attaches a "quarantine" tag to it. This command removes that tag from Auturis.app only — nothing else on your Mac, and it doesn't change any security settings.
   3. Close Terminal, then double-click the app again — it should open normally.

Mac (Intel)

1. Unzip and drag Auturis.app out of the unzipped folder.
2. You'll likely hit the same Trash-only message as the Apple Silicon build, for the same reason — no paid Apple certificate yet. Fix it the same way:
   1. Open Terminal (a built-in Mac app, not something you need to install): press Command (⌘) and Space together, a search box will pop up, type Terminal, then press Return. A window with plain text will open — that's normal, it's just how Terminal looks.
   2. Select and copy the line below (click into it, then Command+C):
      xattr -cr ~/Downloads/Auturis.app
      click into the Terminal window, paste it in (Command+V), and press Return. (If you moved the app somewhere other than the Downloads folder, replace ~/Downloads/ with the folder you moved it to.)
      What this does: when you download a file, your Mac attaches a "quarantine" tag to it. This command removes that tag from Auturis.app only — nothing else on your Mac, and it doesn't change any security settings.
   3. Close Terminal, then double-click the app again — it should open normally.

Once it's open: you'll be asked for your own API key on first launch (BYOK — bring your own key; see further down the page for how to get one, it takes a couple of minutes). Then give it a real question or decision you're actually facing — that's where it gets interesting. If you have a Claude subscription, you can skip the key and use parts of Auturis through Claude instead — see the next section.

Using Auturis with your Claude subscription

If you have a Claude subscription, you can run parts of Auturis through Claude, with no API key: in the Claude desktop app's Code tab, or in Claude Code in a terminal. Auturis's own model calls then run on your Claude plan.

With the plug-in

• What should I do? Test a maxim: whether your principle holds if everyone acted on it.
• What is right? The full rule check: record the groups a rule reaches, state the rule, see what it does to each.

Needs an API key

• Your own graph: building it, seeing it, testing against your own commitments
• The guided dialogue for finding your maxim
• Decide, for yourself or as a group, and Mediate

To set it up, install the Auturis app and keep it open, then give Claude Code this command:
/plugin marketplace add https://auturis.com/plugin/marketplace.json
then /plugin install auturis@auturis. In the desktop app's Code tab, add the same address under + → Plugins. The plug-in comes with the app: use the plug-in, an API key, or both.

Talk to a full model

From October 9, Google's free Gemini offers only Flash-Lite, its smallest model. Flash and Pro now need a subscription.

The matters Auturis exists for are of no small importance to you, so we test models for the capacity for deep reasoning before we recommend them (our test results). In Auturis you know which model answers you, and it is one we have tested. You can talk with it about anything, not only the questions Auturis was built for.

With your own key you pay only for what you use. On GLM-5.3, the model Auturis itself runs on, a message costs a cent or two, so for most people this costs less than a monthly subscription. Your messages go only to hosts that keep no copy of them and do not train on them.

Obtaining your own key

Auturis talks directly to an AI provider using a personal "API key" — like a password just for this. It takes a couple of minutes to get one, no coding involved, and you only pay for what you actually use (usually pennies per conversation). Paste it in where Auturis asks. Never done this before? Step-by-step instructions are here.

Please note that our tests suggest that only undistilled frontier models are able to perform reliably within the Auturis system. Of the models that we have tested, the following are recommended: GLM-5.3, an open-weight model reached through OpenRouter (what Auturis now runs on), Gemini 2.5 Pro, and Claude Opus (test results). Claude Sonnet, while slightly less reliable, may prove sufficient for your purposes. Smaller, cheaper, and free-tier models generally fail our tests. Since there is no general way to know whether a given model is distilled, we recommend that you run whichever model you choose against our "model compatibility check," which is contained within the Auturis program.

Recommended

Gave Auturis the most reliable reasoning in our own testing.

Still workable

Works fine, though it scored lower than the ones above in our own testing.

* OpenRouter keys work in the Mac (Apple Silicon) and Windows downloads now. The Intel Mac download will accept them in its next update; until then, use one of the other keys there.

Your key stays on your own computer. Auturis sends it only to the provider you got it from, never anywhere else.

A Clarification

With some familiarity with this system, it may be objected that once your maxim or your policy rule is identified, you already know whether the proposed action is good or the rule is rightful; that this system, therefore, is not telling you anything that you cannot already determine for yourself without it. But this objection misses the mark. The point of the system is not to be an oracle. It is rather to bring things into the light, which might otherwise never see it, and to bring confidence to those who may need it.
