What is an AI agent?
An AI agent is an AI system that takes actions to finish a task, not just answers questions. You give it a goal; it plans the steps, uses tools such as apps, files, a browser or email, checks the results and keeps going until the work is done, asking you before anything risky.
AI agent vs chatbot
A chatbot answers in text: you ask, it replies, and you do the work. An agent does the work: it can open a file, edit it, export it and send you the result. Most agents use the same AI models as chatbots (Claude, GPT, Gemini, Grok or open models); the difference is that the agent gives the model tools and a loop to use them.
- Chatbot: “Here’s how to resize the banner in Illustrator.”
- Agent: opens Illustrator, resizes the banner to three sizes, exports them and sends you the files.
How an AI agent works
- Goal: you describe the task in plain language.
- Plan: the model breaks it into steps.
- Act: it calls tools: reads files, runs app scripts, clicks on screen, browses, sends messages.
- Check: it looks at each result (often with a screenshot) and corrects course.
- Ask: before a sensitive step, a well-built agent stops and waits for your OK.
- Report: it brings back the result and what it did.
What AI agents can do on a computer
- Edit designs and photos in apps like Photoshop and Illustrator, and export every size.
- Build a presentation in Keynote from your notes.
- Sort, rename and find files across your Mac.
- Research in a browser, compare prices and fill in forms.
- Draft and send email, and reply to messages on WhatsApp.
- Run scheduled jobs, such as a weekly report.
Are AI agents safe?
An agent acts with the access you give it, so the safety rules matter more than the model. Look for an agent that asks before deleting, sending, paying or installing; that treats no answer as no; that can restore deleted files; that limits itself to the folders and apps you allow; and that lets you stop it at any moment. Also check where your data goes: an agent that runs on your own computer keeps your files there.
Local vs cloud agents
Some agents run in the cloud, in a remote browser or virtual machine. Others run on your own computer, where your apps and files already are. A local agent can work in desktop apps like Photoshop or Keynote, and with a local model it can work without sending anything out. A cloud agent needs your files uploaded and can only use web apps.
An example: Wakel
Wakel (وكيل, Arabic for “agent”) is an AI agent for Mac. You connect the Claude, ChatGPT, Gemini or Grok account you already have, or a free local model, and Wakel uses it to work in your apps and files, in Arabic or English. It asks before every sensitive step, costs $25 once and is free for 30 days. Questions about Wakel.
