AuthentiScan

AuthentiScan is a Chrome extension that helps users detect AI-generated content, deepfakes, and verify viral posts. It provides tools for screen recording, screenshot capture, and text analysis, Content you choose to analyse is sent to the project's analysis service (a Supabase Edge Function) for AI analysis; when that service cannot be reached, local heuristics give a fallback result.

Features

• Detect AI-generated text with confidence scores and explanatory reasons
• Detect deepfakes in video recordings or screenshots via AI frame analysis
• Analyze screenshots for AI-generated visual content
• Verify factual claims in text using verification and news cross‑check
• Record screen (full screen or custom area) for video deepfake detection
• Capture screenshots (full screen or custom area) for image analysis
• Context menu item to analyze selected text on any webpage
• View statistics: total scanned, AI detected, verified, flagged, videos analyzed, deepfakes detected
• Bookmark analyzed items for later reference
• Submit feedback on analysis results
• Adjust settings: auto‑scan posts, show badges, theme (light/dark)
