Credibility Analyzer

Evergreen Labs

About this app

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
1. Open the page in Chrome or another app
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
