How Can AI Be Used at Work?
AI tools like ChatGPT, Claude, and Gemini are, in a word, a "fast assistant you can ask in plain words." Even without specialized knowledge, if you talk to it in ordinary language—"summarize this," "draft this email"—an answer comes back in seconds. Beyond text, you can also show it an image, PDF, or figure and ask "make a table from this." This article organizes things so a first-time user can concretely grasp "what it can be used for and how / where it is better not to leave things to it."
There Are Broadly "2 Ways to Use" AI
Even with the same AI, what comes back changes depending on how you ask. Knowing this difference first makes everything much clearer.
| Chat | Agent | |
|---|---|---|
| What it does | You ask a question → AI answers in text | You ask "do this for me" → AI actually does the work and finishes it |
| What you get | Advice or a draft in text | A finished file, or the result of the action it performed |
| Mental image | A knowledgeable colleague you can consult | An assistant who carries out the work for you |
Chat examples: "Summarize these minutes in 3 lines," "Draft a polite apology email," "List 5 risks of this plan." You copy the returned text and use it yourself.
