# AI FactScan

AI FactScan is a browser extension that grades citation sources in AI answers from A to F, helping users spot weak, missing, self-referential, or low-quality sources before relying on an AI response.

## What it does
- Extracts citation links from AI answers and pasted text
- Grades citation source quality from A to F
- Flags invalid links, AI self-references, resolver failures, and content-farm or review-recommended sources
- Shows source proportion and concentration so users can see whether an answer relies on narrow or weak source clusters
- Provides optional Supporter cloud source-signal lookup and full HTML report export

## What it does not do
- It does not determine whether an AI claim is true or false
- It does not replace reading the cited source or using professional judgment

## How to use
- Open an AI answer that includes citations or source links
- Click AI FactScan and select the citation block on the page, or paste the AI answer into the extension
- Review the A-F source grades, source proportions, and warning signals
- Open C, D, or F sources directly before relying on or citing the AI answer
- Ask the AI tool for better sources when citations are missing, weak, self-referential, or invalid

## Who it's for
Students, educators, researchers, knowledge workers, journalists, analysts, and AI users who want a faster way to evaluate the quality of sources cited by AI chatbots.

## Supported platforms
ChatGPT, Claude, Gemini, Perplexity, DeepSeek, Microsoft Copilot, Grok, and pasted AI responses from other tools.

## Key differentiator
AI FactScan focuses on citation source quality, not AI-text detection. It helps users answer: "Are these citations worth trusting or reviewing more carefully?"

## Pricing
- Free: 5 citation scans per day, no account required
- Supporter: unlimited citation scans, cloud source signals, citation verification checks, source concentration analysis, and HTML report export
- Supporter licenses may be used with up to four browser installations
