  • For writing code

    Theus CLI

    A coding agent that lives in your terminal, understands your project because it indexes it on your own machine, and brings its help, its diagnostics and its arsenal with it.

    Why the index lives on your disk →

  • For the browser

    Theus Chat

    A chat where the agent runs your code in an isolated sandbox, hands the files back, and lets you carry that same conversation into your terminal with one command.

    How a session jumps from browser to terminal →

  • Free · MIT

    Ñaupa

    An engine that reads your whole repository and builds the map of what calls what, so your agent knows what breaks if you touch something — without re-reading a single file.

    Why a graph and not a search box →

  • For repeating tasks

    Kuti

    You do a browser task once while Theus watches, and from then on it repeats it whenever you ask.

    A 33-line script you can actually read →

  • For your company

    Atlas by Theus

    A console where your company builds its own agents, gives them its documents and hands out permissions by department, under one account and one invoice.

    What a console governs →

Your next project starts here.

For your business, your clients, or the idea you want to bring to life: get help choosing a model and continuing your work.

  • #1 It decides

    TITAN picks for you

    Engraving: Hermes with the winged helmet among rings and constellations

    TITAN weighs every task and routes it to the exact model — 190 models on a single account, with no provider keys.

    For example: “Check why my store’s sign-up form is not working.”

    Model access depends on your plan; no separate provider keys are needed.

  • #2 Your pace

    One account. Your choice of plan.

    Engraving: a hand drops coins that turn into lightning

    Use the models included in your plan through one Theus account. Your usage depends on the model and the task, and you can review it from your account.

    Choose a plan based on how you work.

    Usage depends on the model and the task.

  • #3 It remembers

    Memory on your disk

    Engraving: the muse of memory surrounded by scrolls

    The CLI stores your project index and memory on your machine so you can resume your work. When you use a remote model, the context it needs is sent to that service.

    Today’s project is tomorrow’s starting point.

    When using a remote model, the necessary context is sent to that service.

  • #4 Your language

    Speaks your language

    Engraving: an Andean valley with the city in the distance

    An agent that codes and talks in your language — English, Urdu or Spanish, all the way down to theus --help.

    For example: “Explain this error and help me fix it.”

    Use theus --help to see the available CLI commands.

TITAN · The judgment behind Theus

You set the goal.
TITAN picks the path.

You do not need to know every model to get started. Describe your task: TITAN considers capability, cost, quality, and availability to choose a route.

Illustrative example · No real evaluation is executed

“Review my application’s sign-in flow”

One goal, several decisions before working on the code.

01 / 04

Understand the goal first.

This example concerns code and security: reviewing how someone signs in to an application.

  • Capability
  • Cost
  • Quality
  • Availability

This sequence explains the concept. It is not a live comparison or a guarantee of results.

Multiply your work.

Two tools to move forward: one connects the pieces of your code. The other preserves how you complete a task so you can repeat and share it.

Ñaupa

Ñaupa · Free · MIT

Engraving: an Andean chakana woven from a graph of nodes

Before changing something, understand what depends on it.

Ñaupa reads your project and maps connections between files and functions. The map helps the agent find relevant code and explore what a change might affect.

Free and MIT licensed. Runs on your computer, with or without a Theus subscription.

Kuti

Kuti · Automation

Engraving: hands weaving a circuit pattern on a loom

Your way of working, ready to repeat.

Show how you complete a browser task. Kuti turns it into a script you can save, run again, and share with your team. The process no longer depends on one person remembering it.

Discover Kuti

  1. You record

    You do the task once, the way you always do. Theus watches.

  2. It shows you the plan

    Before repeating anything, it tells you what it understood and what it will do.

  3. It repeats it

    Whenever you want, as many times as you want. And it adapts if the page changed.

Learned once. Ready to share.

Check it yourself

Go from seeing
to trying.

Start with Ñaupa without creating an account. Then explore Theus models and available top-ups. You decide how far to go.

  1. No registration

    No account, no email

    Ñaupa parses the AST of 158 languages and builds the graph of your repo. Binary verified by SHA-256.

    What else Ñaupa does →

    In your terminal

    $ curl -fsSL https://theus.pe/naupa.sh | bash

    This command installs Ñaupa. Its guide explains how to analyze your project.

  2. With your free account

    The catalogue, and how far your plan reaches

    Install the CLI and sign in on the free plan. Inside the session, type /modelos and the whole catalogue comes out.

    Installation guide →

    In your terminal

    $ curl -fsSL https://theus.pe/install.sh | bash

    After installing, open Theus and sign in. Then type:

    /modelos

    Seeing the catalogue does not mean every model is included in your plan.

  3. With an active session

    Top up without leaving the terminal

    Credit packs bought from inside the session. The balance sits behind your quota and never expires.

    See plans and top-ups →

    Inside the session

    /recarga

    The command opens top-up options. A purchase takes place in a later step.

Who signs this

I build Theus from Lima.And I sign it with my name.

I have been programming since 2016 and building companies since I was 18. I lead a team of eight that builds software for verticals where a demo is not enough: banking, pharmaceuticals, mining — where the system has to survive an audit, not just a demonstration.

Theus comes out of that school, and out of a conviction: the world should not have to rent its artificial intelligence — it should be able to build it. That is why the index lives on your disk, and why this page does not ask you for faith: every claim has the command that proves it right next to it.

  • Software in production since 2016
  • 800,000+ users on our own platforms
  • 36 vulnerabilities reported to Peru's electoral authority

Preguntas frecuentes

Antes de empezar.

What is Theus?

Five products under a single account: the CLI (an agent in your terminal), the chat, Ñaupa (a free engine that reads your repository), Kuti (records and replays browser tasks) and Atlas (a console for companies). The index and the memory live on your disk.

How is the chat different from the CLI?

The CLI works on the files on your machine: it indexes the repository on your disk and edits your project. The chat lives in the browser and runs code in an isolated sandbox; what you start there can continue in your terminal with one command. Both are in the same subscription.

How do I pay from Pakistan?

By international card, in US dollars, through Stripe — the same rail as anywhere outside Peru. Prices shown in rupees are a reference for the exchange rate; the amount your bank sees is the dollar figure. Peruvian customers have a separate rail in soles.

Is Theus available in English and Urdu?

Yes. The site, the CLI and the chat all run in English, and Urdu is available across the site with right-to-left layout. The agent itself answers in whichever language you write to it in.

Does it work on Windows?

Yes, there is a native Windows x64 binary that installs from PowerShell in one line. The macOS binaries are signed and notarised.

Which models does the subscription include?

A catalogue of 190 models for code, reasoning, agents and multimodal work, plus image, video and voice. Each plan unlocks the one below it and adds its own tier; the free plan opens 2. TITAN analyses each task and picks the best route.

Do I need my own API keys?

No. Theus configures the routes included in your plan centrally. If you prefer, from the CLI you can configure your own keys or point at a local model on your machine.
