# Sentiment Analysis

> How Octolens classifies each mention as positive, neutral, or negative, and how to use sentiment in feeds, destinations, and the dashboard to spot brand risk early.

Octolens automatically analyzes the **sentiment** of every mention it finds, classifying each post as **positive**, **neutral**, or **negative**. This helps you quickly identify praise, complaints, and everything in between.

## How sentiment is used

Sentiment is available as a filter throughout Octolens:

* **In any feed:** filter mentions by sentiment to focus on what matters most. See [Feeds](/docs/quickstart/feeds).
* **As a feed filter:** build feeds based on sentiment. For example, a feed for only positive or negative mentions about your brand.
* **In destinations:** any sentiment-scoped feed can be sent to Slack, email, or a webhook. See [Destinations](/docs/quickstart/destinations).
* **On the Dashboard:** break the Mentions over time chart down by sentiment to see the positive/neutral/negative split day by day. See [Dashboard](/docs/learn/dashboard).
* **Via MCP:** ask the [MCP server](/docs/mcp/overview) about sentiment trends in natural language.
* **In the API:** filter mentions by sentiment programmatically. See [API Reference](/docs/api/v2/overview).
