What you try. What you pay for.

Theus manages access to AI models for working with code. Your subscription buys usage capacity and your plan's models, not the free Ñaupa engine.

  • Free and Ñaupa

    Free lets you try Theus with a limited allowance. Ñaupa is a separate free engine; you do not need Theus Pro to use it.

  • Your subscription

    Provides the enabled models and your plan's included usage in 5-hour and weekly windows. CLI and Chat share the account. It does not include unlimited usage or every Theus service.

  • Top-ups

    Add balance without changing the plan. They are separate purchases, not subscription payments. Check the payment options available for your account and country.

Terms and privacy

Usage depends on the model, context and response. A credit allowance does not equal a fixed number of tasks or working days.

CLI and Chat use your Theus account. Downloading Desktop does not start a subscription. Connected models have their own quotas and terms. Atlas is offered separately. Ñaupa's index is local. When using a remote model, shared context may be sent to that connection's provider.

First, something useful for you

What do you want to work on today?

Choose a goal. We will prepare a first instruction in the chat; review it and send it when you are ready.

Want to work on your repository? Start with the CLI

Give your idea a starting point.

Define what to build, break down the work and ask for the first code. Choose the CLI to work on your local files.

Your starting instruction

I want to create a page for a project. First ask me three questions: what it does, who it is for and what action visitors should take. Use my answers to propose a simple structure, then help me build a first version. Do not invent testimonials or results.

This is a template, not a generated result. You can edit it before sending.

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 — 192 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.

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.

How do credits work?

Usage depends on the model, context and response. A credit allowance does not equal a fixed number of tasks or working days. A top-up adds usage balance. It does not change your plan, unlock higher-tier models or pay for your subscription. It is used after the included allowance. How long it lasts depends on your tasks and models.

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?

Theus brings together Desktop, the AI coding assistant for Mac; the terminal CLI; browser chat; Ñaupa, the free code intelligence engine; Kuti for replaying browser tasks; and Atlas, the enterprise agent console. Ñaupa needs no account or subscription. Model usage depends on your plan and connection; Atlas has its own commercial terms.

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 192 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.
