AI Desktop Agents: Let AI Get the Work Done on Your Computer
A look at AI agents that can work with your files, email, and web pages—Claude Cowork, Perplexity Computer, the Gemini desktop app, ChatGPT Work, Manus, and Microsoft Copilot—compared by where they run, what they can access, and what they require, with advice on setting permission boundaries.
In September 2026, Gemini shipped a Windows desktop app, Perplexity brought Portable Computer—which plans and runs multi-step tasks on your own machine—to Windows, and ChatGPT Work began reading connected Gmail, Slack, and cloud drives. AI assistants are moving from answering questions to acting with your permissions. This collection picks desktop agents by where they run and what they can touch, and puts the most overlooked issue up front: the more an agent can reach, the more a mistake costs.

| Claude Cowork | Isolated cloud environment | Desktop app and cloud sessions | Batch document, spreadsheet, and recurring report work | Activity not yet in audit logs or compliance APIs |
| Perplexity Computer | Cloud, or on-device (Portable Computer) | Mac / Windows app | Research and multi-step tasks with sensitive data | Local Windows version needs 24GB VRAM |
| Google Gemini | Cloud | Windows / Mac desktop app | Everyday tasks in Google's office suite | Personal agent Gemini Spark needs a subscription |
| ChatGPT Work | Cloud | Web and mobile | Drafting from email, Slack, and drive content | Access scope depends on account and admin settings |

FAQ
- Q: How is a desktop agent different from a regular AI chatbot?
- A: A chatbot answers and you do the work; a desktop agent, once given access to folders, email, or a browser, breaks the task into steps, carries them out, and hands back the result. The trade-off is reach: a mistake stops being a wrong sentence and becomes a wrongly edited file or a sent email.
- Q: What should I watch for when granting an agent access?
- A: Grant only the folders and accounts the task needs; keep a human confirmation on deleting, sending, and paying; and don't leave passwords or verification codes in mailboxes or documents the agent can read. According to The Information's September 2026 report, Meta's unreleased personal agent Hatch used a user-granted Gmail connection to change a website account's password during employee testing—the problem wasn't a jailbreak, it was what the agent could reach.
- Q: I don't want data in the cloud. Is there a desktop agent that runs locally?
- A: Yes, but the hardware bar is high. Perplexity Portable Computer launched on Windows on September 14, 2026, with the model, planner, and scheduler all running on the machine; it needs an NVIDIA RTX GPU with at least 24GB of VRAM, is included in Pro and higher plans, and asks before escalating to a cloud model. Hybrid Compute on Mac hands steps involving sensitive data to a local model and needs at least 24GB of unified memory. If your hardware falls short, see the Local LLM Deployment collection.
- Q: Can these tools be used in mainland China?
- A: Claude, ChatGPT, Gemini, and Perplexity require your own network arrangements to access from mainland China, and Manus officially does not serve mainland China. For company data, also check your organization's data-export and compliance rules first.
