BladeRunner for Web

BladeRunner — Browser add-on for spotting AI-written text

BladeRunner is a browser extension built to detect and mark passages likely created by artificial intelligence. It integrates directly into your web browser and analyzes page content on the fly, flagging suspicious snippets so you can quickly tell machine-written passages from human-written ones.

How it works in your browser

When enabled, the extension inspects text as pages load or while you scroll. Suspect passages are visually emphasized and a probability indicator is shown alongside them, giving an estimated likelihood that the content was generated by an AI model. Detection happens in real time so alerts appear during normal browsing without interrupting your flow.

Core capabilities

• Highlights segments of the page that appear to be AI-produced.
• Provides a numerical confidence level for each flagged passage.
• Scans pages instantly as you browse, delivering immediate feedback.
• Spots synthetic content types such as fake product reviews, bot-generated comments, and misleading news stories.

Practical areas of use

• Education: helps instructors and students identify machine-written submissions.
• E-commerce: detects fraudulent or manufactured reviews that can mislead shoppers.
• Government and public sector: assists in filtering propaganda or coordinated misinformation.
• Social networks and forums: uncovers bot activity and automated comment campaigns.
• Cybersecurity teams: aids in spotting text-based social-engineering attempts.

Benefits and purpose

BladeRunner’s goal is to help users navigate an internet increasingly filled with synthetic text. By combining on-page highlighting with confidence metrics, it supports faster assessment of content credibility and reduces the effort required to spot spam, deceptive articles, or automated campaigns.
