Pangram

What it does

Pangram's extension checks whether text or images on any page were created by AI, using Pangram Labs' detection model. It is aimed at educators, editors and readers who want to judge what they see on social feeds, blogs and Google Docs.

Key features

• Right-click any text or image to check it for AI content
• Labels posts on X, LinkedIn, Substack, Reddit and Medium as Human, AI-Assisted or AI
• Sidebar shows the share of human versus AI content in your feed
• Automatically scans images as you browse
• In Google Docs, shows edits, pasted blocks and a replay of the writing history

Use cases

• Reviewing a student essay written in Google Docs
• Checking how much of your social feed is AI-generated
• Verifying an image before using it in an article

Getting started

Install and pin the extension, create a Pangram account, then highlight text or right-click an image and choose to check it for AI.

Good to know

A Pangram account is required. Detection results are estimates, so use them alongside other evidence rather than as a final verdict.
