## What is sentiment analysis?

Sentiment analysis reads text and works out how the writer feels: positive, neutral or negative. Social teams use it on comments, mentions and reviews to see whether a launch landed, which complaints are growing, and what customers love.

## What to paste

**Social comments**

Copy the comments under a post or an ad and see how they split.

**Reviews**

App store, product or location reviews, one per line.

**Survey answers**

Open-text answers from NPS or CSAT surveys.

**Support messages**

Find the topics behind negative feedback.

## How the labels work

An AI model reads every line on its own and labels it positive, neutral or negative. A second pass names 4 to 8 themes from your text and puts each line in one of them. Net sentiment is the share of positive lines minus the share of negative lines, from -100 to +100.
