Credibility Analyzer

Credibility Analyzer helps you judge whether selected text, a page URL you share, or a photo is reliable.

From Chrome or any app, send text, a link, or a photo into the app and get:

• A credibility / factualness score from 1–10

• A short justification of that score

• Clear bullet-point findings

• Source links when Gemini web grounding returns citations

• Results in the same language as the content when possible

How to use — select text

1. Highlight text in Chrome, Messages, or another app

2. Tap ⋯ (or Share) and choose Credibility Analyzer

3. Review the score, findings, and sources

How to use — share a page URL

2. Tap Share → Credibility Analyzer

3. We’ll fetch and fact-check the page — no need to select text

How to use — share a photo

1. Open a photo or screenshot

2. Tap Share → Credibility Analyzer

3. Review the score, findings, and sources
