Copyseeker: AI-Powered Reverse Image Search for Fact-Checking and Fraud Prevention

Copyseeker is an advanced AI reverse image search platform. You upload or paste an image to trace its origin, find duplicates, and verify authenticity. Key features include pixel-level matching for exact duplicates, authority-weighted ranking of sources, and high-recall detection of reuse across the web. Copyseeker also offers a Chrome right-click extension and a developer API for programmatic checks. Use it at https://copyseeker.net.

How Reverse Image Search Works (Glossary Overview)

• Content-based image retrieval (CBIR): Searches by image content rather than text, leveraging perceptual hashes and deep visual embeddings to match exact and near-duplicate images.

• Perceptual hashing: Generates compact fingerprints resilient to minor edits like crops, resizes, and recompression. Good for duplicate detection.

• Deep embeddings: Neural networks map images into a vector space; nearest-neighbor search retrieves visually similar items even when heavily edited.

• Authority-weighted ranking: Results prioritize credible sources and de-emphasize low-quality domains, improving verification utility.

Platform Features at a Glance

• Pixel-level duplicate detection: Flags exact or near-exact copies, even after minimal edits.

• Authority-ranked results: Surfaces likely originals and reputable hosts first.

• Evidence-ready result pages: Consolidate appearances, timestamps, and links for audit trails.

• Chrome extension: Right-click any image on the web to search via Copyseeker. 

• API access: Integrate reverse image checks into your CMS, trust-and-safety pipeline, or brand-protection tools. (copyseeker.net)

Mobile: Image Search by Copyseeker for iOS

Image Search by Copyseeker brings a reverse image search app to iPhone and iPad for on-the-spot verification. 

High-leverage use case: catching scams and fake profiles

Fraudsters often recycle profile photos across dating apps and social platforms. Reverse searching a suspicious avatar quickly reveals reuse patterns. Copyseeker’s iOS app is designed for this scenario and for general OSINT checks. 

Workflow on iOS

1. Save or long-press a suspicious profile image.

2. Share it to Image Search by Copyseeker or open the app and select from Photos.

3. Review matches to see where else the face or photo appears.

4. Check for mismatched identities, stock-photo sources, or old leaks.

Red flags the app helps expose

• Same headshot on multiple names or platforms.

• Photo traced to a stock site, news article, or unrelated biography.

• Heavy edits that still map to an older, widely used image.

• Reverse timeline: earliest appearance contradicts the claimed story.

Practical Tips and Limits

• A match is evidence, not a verdict; corroborate with additional signals.

• Lack of matches does not prove authenticity; some images are new or offline.

• For investigations, keep original files and note capture dates to preserve context.

When to Use Web vs. Mobile

• Web platform (Copyseeker.net): Deep, evidence-rich checks, bulk or API workflows, and thorough source vetting.

• iOS app: Fast, on-the-go verification when you need answers in seconds. (Apple)

Bottom line: Use the web platform for comprehensive provenance analysis and the iOS app for immediate spot checks. Together they make image verification routine, helping you stay safe online and avoid digital fraud.
