EyeSift

EyeSift helps students, editors, marketers, and teams evaluate whether text appears human-written or AI-generated. It provides fast browser-based AI text analysis with clear detection signals and no account required for basic checks.

Key Features

• AI text detection — perplexity scoring, burstiness analysis, n-gram pattern matching, and vocabulary entropy to flag likely AI-generated writing
• Humanized AI detector — catches AI text that has been rewritten or paraphrased to evade standard detectors
• Image analysis — EXIF metadata inspection, GAN fingerprint detection, and visual artifact scanning
• Video analysis — frame-by-frame deepfake detection using temporal coherence and motion pattern analysis
• Audio analysis — spectral analysis and synthesis marker detection for AI-generated voices
• Plagiarism checker, grammar checker, paraphraser, summarizer, readability scorer, tone analyzer, and keyword density tool
• False positive calculator and AI appeal letter generator — useful when legitimate writing gets incorrectly flagged
• Downloadable AI detection reports for formal review workflows
• Browser-first — no file uploads, no account, no API keys required

Pricing Structure

Free — all 25 tools are available at no cost with no account required and no usage limits stated. The site is ad-supported. An embeddable widget is also available for teams wanting to add detection to their own platform. View all tools at eyesift.com.

Why People Use It

As AI-generated content becomes harder to spot by eye, teachers, editors, recruiters, journalists, and legal teams all need a fast first-pass screening tool before committing time to a deeper review. EyeSift covers all four media types in one place — most competing tools only handle text. The browser-side processing is a meaningful privacy advantage for anyone handling student work, unpublished manuscripts, or confidential documents that shouldn't leave the device. It also stands out for its transparency: the methodology is published, scores come with signal breakdowns rather than a single opaque number, and the site actively warns users to treat results as a starting point rather than proof — which is the responsible position given how often AI detectors produce false positives on human writing.
