# AI Auto Tags & Summary

> Every conversion auto-generates semantic tags and a concise summary powered by AI.

## Overview

When you convert a page, Web2MD automatically generates:

* **1-2 sentence summary** — A concise overview of the content
* **3-5 semantic tags** — Lowercase English tags for categorization

This happens in the background (\~1-2 seconds) powered by the Doubao AI model.

## How it works

<Steps>
  <Step title="Convert a page">
    Convert any webpage using Web2MD.
  </Step>

  <Step title="AI analyzes content">
    The first \~4000 characters are sent to the AI model for analysis.
  </Step>

  <Step title="Tags appear">
    Summary and tags are displayed below the conversion result as colored pills.
  </Step>
</Steps>

## Tag-based filtering

In the **History** tab, you can filter your conversions by clicking any tag. This lets you quickly find all articles about a specific topic.

## PRO feature
