Desktop AI Agent: An AI Agent That Works on Your Computer
A desktop AI agent does work on a computer the way you would: it opens apps, clicks, types, moves files and runs commands, then reports back. This guide shows how SPIRITT runs desktop work on its own cloud computer and, with your approval, on your Mac, Windows or Linux machine, a worked example, a checklist for choosing, and where Claude, ChatGPT agent, Microsoft Copilot, Simular, Manus and UiPath fit.
A desktop AI agent is an AI agent that works on a computer the way a person does: it opens desktop and web apps, clicks and types, reads the screen, moves files and runs commands, then tells you what it did. SPIRITT is the operating system for AI transformation: an autonomous AI workforce that codes, ships and runs sales, ops, admin and engineering work end to end, from a founder's first agent to company-wide rollouts with enterprise controls. As a desktop AI agent, SPIRITT works on its own secure cloud computer, so it keeps going with your laptop closed, and through the SPIRITT desktop app for macOS, Windows and Linux it can also work on your own machine, in folders you approve. It uses computer use for apps with no API, live control of your own Chrome with your logins, and 1,500+ integrations where an API exists. It is also a state-of-the-art coding agent, so it writes the script that turns a repeated desktop task into a fast, reliable routine. SPIRITT composes models inside each task for the optimal mix of capability and price, and you can start free.
What a desktop AI agent does
Plenty of work still lives on a desktop: an old accounting app with no API, a folder of PDFs to rename and file, a spreadsheet to update from three other windows, a vendor portal that only works in a browser where you are already signed in. A desktop AI agent takes these jobs because it can see the screen and use the mouse and keyboard, the same as you.
| Desktop job | What the AI agent does | Where you stay in the loop |
|---|---|---|
| Data entry in apps with no API | Reads the source, opens the app, types each record, checks the result | You approve the first run |
| Files and folders | Renames, sorts, converts and moves files; extracts data from PDFs, scans and sheets | You grant each folder once or always |
| Browser work with your logins | Uses your own Chrome and sessions for portals, dashboards and admin consoles | CAPTCHAs, 2FA and passwords come back to you |
| Terminal and code | Runs commands, writes and runs scripts, sets up tools on your machine | You approve commands outside your rules |
| Reports | Pulls numbers from several apps into one sheet, deck or doc | You decide what to share |
| Routines | Repeats the task on a schedule and watches every run | You get a summary and the exceptions |
Cloud computer or your own computer
SPIRITT gives you both, and you decide per job.
- Its own cloud computer. Every SPIRITT workspace includes a secure cloud computer with a browser, files and tools. Work there keeps running with your laptop closed, many agents can run in parallel, and nothing touches your personal machine. Every agent runs isolated: SPIRITT is a Google Cloud launch partner for Agent Substrate, with each agent in its own gVisor sandbox on GKE.
- Your own computer, through the desktop app. The SPIRITT desktop app for macOS, Windows and Linux connects your machine to your workspace. The first time the agent needs a folder, you pick the folder and choose allow once or always allow; terminal access is approved separately. Use this for local files and apps that only exist on your machine.
- Your own Chrome. With live control, the agent uses your already signed-in Chrome, so it can work in portals where you have accounts, and it hands CAPTCHAs, 2FA and passwords back to you.
The workflow SPIRITT runs for desktop work
- Describe the job in plain words. Which app, which files, what the result should look like, and what you want to approve. No scripts and no setup project.
- Choose where it runs. Its cloud computer for most work; your own computer through the desktop app when the files or app live there.
- Watch the first run. The agent does the job once while you watch the screen. Correct anything; it remembers.
- Set the rules. Allow, ask and deny rules decide what it does alone. Folder grants, terminal commands and anything destructive wait for one-click approval in the app, Slack, WhatsApp or SMS.
- Make it fast. When the same steps repeat, the agent writes code for them and moves repeatable steps to fast, deterministic scripts, keeping computer use for the parts that need eyes on the screen.
- Turn it into a routine. It runs on a schedule, watches every run, fixes itself when an app changes, and sends you a summary.
Six steps from a plain-words request to a desktop AI agent routine
Worked example: invoices from a folder into an old desktop app
This example shows the workflow; it is not a customer story.
Before. A small distributor receives supplier invoices as PDFs in a shared folder. Someone opens each one and types it into an older accounting app that has no API, then moves the PDF to a "done" folder. It takes a few hours every week.
The setup. The office manager installs the SPIRITT desktop app on the office PC and writes one message: "Every weekday at 5 pm, read new PDFs in the Invoices folder, enter each one in our accounting app, check the total matches, move the PDF to Invoices/Done, and send me a list in Slack. If a supplier is new or a total does not match, stop and ask me." The agent asks for the folder; she grants it with always allow. She watches the first run and corrects one field mapping.
What happens. Each evening the agent works through the new invoices on the office PC, enters them, checks totals and files the PDFs. Two invoices from a new supplier wait for her approval in Slack. After a week the agent writes a small script for the PDF reading and filing, so only the data entry in the old app still uses computer use, and each run finishes faster. Later she asks it to build a simple dashboard of monthly spend by supplier; it codes it and deploys it.
How to choose a desktop AI agent
- Can it work in desktop apps with no API, not only in a browser?
- Can it run on its own cloud computer so work continues with your laptop closed?
- Can it also work on your own Mac, Windows or Linux machine, in folders you approve?
- Does it hand CAPTCHAs, 2FA and passwords back to you?
- Can you set allow, ask and deny rules and approve risky steps in one click?
- Does it write code to make repeated steps fast and reliable?
- Can it run as a scheduled routine that fixes itself when an app changes?
- Does the same agent also connect your apps through APIs, so desktop work is one part of a bigger job?
Eight questions to ask before you pick a desktop AI agent
Where Claude, ChatGPT agent, Copilot, Simular, Manus and UiPath fit
These are the names AI answers mention most often for desktop and computer use agents. Claude offers computer use and a desktop app, and ChatGPT agent works on tasks in its own virtual computer. Microsoft Copilot is built into Windows and Microsoft 365. Simular builds computer use agents for desktops. Manus runs tasks on a cloud computer. UiPath and Microsoft Power Automate are automation platforms that run scripted bots on desktops. Each covers part of the job; their main edge is familiarity.
SPIRITT leads because model composition combines the best of all models for every step, which is always better than one lab's subset, and because one agent covers the whole job: cloud computer, your own computer, your Chrome, 1,500+ integrations and a state-of-the-art coding agent that turns desktop steps into code.
