Engraving: beneath a classical pediment, five figures — one writes on a tablet, one holds a sphere of light, one unfurls a map, one weaves at a loom and a king wields a sceptre

What each one does

Each one solves a different moment.

  1. Theus engraving: a figure with a sword before tablets of code

    Producto 01 · Mac and Windows

    Theus Desktop

    Code with AI in your Mac or Windows repositories. Conversations, files and terminals together to understand the project and review changes.

    • Persistent conversations and projects let you continue working when you reopen the application.
    • Files, activity and terminals alongside the conversation. Less scattered context, more clarity.
    • Inspect differences, work with version control and configure approvals to match your workflow.

    What it does not do yet

    Published installers are for Apple silicon and Intel Macs and Windows x64. Connected models and services may require internet access and receive the context you share.

  2. Engraving: a figure seated on a pedestal wields a sword before tablets of code, a halo of lightning behind

    Producto 02 · 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.

    • The index lives on your disk: symbols, graph and memory in ~/.theus/knowledge
    • It does not tie you down: your own key, your gateway or a local model
    • You top up from the terminal, without opening a browser

    What it does not do yet

    The index it ships with reads JavaScript and TypeScript. Every other language is covered by Ñaupa.

    Why the index lives on your disk →
  3. Engraving: a braided woman consults a crystal sphere showing a lit city

    Producto 03 · 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.

    • It really runs, it does not imagine: hardened container with no network
    • The conversation jumps to your terminal with one command
    • Projects, memory and an editable canvas

    What it does not do yet

    Of the 15 connectors, 10 link with one click from the browser; the other 5 only from the CLI.

  4. Engraving: an Andean chakana with a gear at its centre, woven from a graph of nodes and edges

    Producto 04 · 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.

    • Ask in plain language; it answers with a file and a line
    • It knows what breaks before you touch it
    • Free, MIT, no account: a static binary in one line

    What it does not do yet

    The analysis is static: it does not see what is called by reflection, nor handlers resolved by dynamic strings.

    Why a graph and not a search box →
  5. Engraving: hands weave a circuit-patterned cloth on a wooden loom

    Producto 05 · For repeating tasks

    Kuti

    You do a browser task once while Theus watches, and from then on it repeats it whenever you ask. It lives inside the CLI: the same subscription.

    • What was recorded is read before it runs: a script that fits on one screen
    • It stops on its own before anything irreversible: a captcha or confirmation calls a person
    • It is shared without copying the password: a portable script

    What it does not do yet

    The browser half — recording while watching the page, capturing clicks and replaying — needs the extension, which travels inside the program since 1.2.2 but is not in any store yet.

    A 33-line script you can read before running it →
  6. Engraving: in a columned hall, a figure with scales leads a line of shielded automata

    Producto 06 · 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.

    • One identity for the whole company, per organisation
    • Agents you configure yourself, with a private knowledge base
    • Bought separately from the subscription: three plans of its own

    What it does not do yet

    Atlas is an agent builder, not a catalogue of ready-made processes: your department's flow is something you configure.

    What a console governs that a loose chat does not →

Frequently asked about the products

Before you choose.

  1. How many products does Theus have?

    Six: Theus Desktop, Theus CLI, Theus Chat, Ñaupa, Kuti and Atlas by Theus. The first five are for writing code; Atlas governs your team.

  2. Do I have to pay for each one separately?

    Not all of them. The CLI, the chat and Kuti are in one subscription from USD 31. Ñaupa is free. Atlas is contracted separately.

  3. Which one suits me if I am just starting?

    Theus Chat: you install nothing, you open the browser and the agent is already running code in an isolated sandbox.

  4. Do they work together?

    Yes, and that is why they are not six separate purchases. Kuti is three commands inside the CLI; Ñaupa mounts on top of any agent.

  5. Which one is free?

    Try CLI and Chat with the Free allowance, without a card. Ñaupa is free and independent of every plan.

  6. Where does my code stay?

    The CLI index and the Ñaupa index are built and live on your disk. When a cloud route is used, only the session's context travels.

  7. How is it billed outside Peru?

    In US dollars, by international card, from USD 31 a month — and top-ups are bought from inside the terminal, without opening a browser.
