# Overview

> What DeepVerify is and how to install the Chrome extension

## What is DeepVerify?

DeepVerify is Factagora's Chrome extension for fact-checking content in real time as you browse: highlight a claim, scan a whole page, check a YouTube video against its captions, or follow a live conversation, without leaving the tab.

## Installation

<Steps>
  <Step title="Install the extension">
    Get DeepVerify from the [Chrome Web Store](https://chromewebstore.google.com/detail/deepverify-ai-fact-checke/eajnhepckmoblclljcnhlcofiamhfeel).
  </Step>

  <Step title="Sign in">
    Click the DeepVerify icon in your browser toolbar and sign in with your Factagora account. Checking requires an account.
  </Step>

  <Step title="Run your first check">
    Open an article, press <kbd>Alt</kbd> + <kbd>F</kbd> to open the side panel, and press **Check this page**. Claims appear one at a time with their verdicts.
  </Step>
</Steps>

## How it works

DeepVerify splits what it does into three steps, and every mode follows the same three.

<Steps>
  <Step title="Find the claims">
    Text is read from the page, the video's captions, or live speech, and the statements that can actually be checked are pulled out. Opinions and questions are left alone.
  </Step>

  <Step title="Check each one">
    Each claim is verified against sources and gets a verdict, a confidence score, and the documents used to reach it.
  </Step>

  <Step title="Score the whole thing">
    The individual verdicts roll up into a Trust Score for the page or video, mapped to one of five reliability tiers.
  </Step>
</Steps>

## The side panel

Everything lives in the side panel, reached with the toolbar icon or <kbd>Alt</kbd> + <kbd>F</kbd>. The icon rail on the right switches between:

| Panel          | What it does                                             |
| -------------- | -------------------------------------------------------- |
| **Fact Check** | Check the current page, a selection, or a YouTube video  |
| **Live**       | Transcribe and check microphone or tab audio as it plays |
| **History**    | Revisit earlier checks and re-run them                   |
| **Settings**   | Account, appearance, and automatic-checking options      |

## Requirements

* Google Chrome version 114 or later
* A Factagora account (free tier supported)
* Active internet connection
* For YouTube: the video must have captions, since checking works from the transcript

## Pricing

DeepVerify is billed separately from the Factagora API, on its own Free / Pro / Max plans. The free tier covers 3 documents a day. See [Pricing](/guides/deepverify/pricing) for the full comparison.
