# 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 |

## What DeepVerify reads

DeepVerify does not read every page you visit. It reads a page's text only where you have turned on automatic checking. With automatic checking off, it only looks at the sentences you select yourself.

On sensitive sites such as internal documents or account pages, pause the extension from the toolbar icon.

Microphone and tab audio are captured only while a Live session is running, and only after you grant the browser permission the first time.

## 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.
