What it is

Sentiment analysis is when AI reads text and works out whether the person writing it is happy, angry, confused, or somewhere in between. Companies use it to scan thousands of customer reviews, social media mentions, or support tickets and get an instant read on how people feel. It's not perfect. It struggles with sarcasm, cultural context, and the British habit of saying "fine" when things are very much not fine. But for spotting broad trends across massive volumes of text, it's surprisingly useful.

Why it matters for your job

If your role involves understanding customer feedback, monitoring brand reputation, or tracking employee satisfaction, sentiment analysis tools can process in minutes what would take a team weeks to read manually. This doesn't mean those roles disappear. It means they shift from "read everything and summarise" to "interpret the AI's analysis and decide what to do about it." The human part of the job becomes the strategy, not the reading.

What to do about it

Try running a batch of customer feedback through an AI tool and ask it to categorise the sentiment. Compare its readings to your own judgement. You'll quickly see where it's spot-on and where it's hopeless. That knowledge makes you the person who can use these tools without blindly trusting them.
