How EyeSift AI Detection Works
EyeSift groups AI detection, writing analysis, and utility tools into one free browser-based suite. Detection tools use multiple signals such as statistical patterns, linguistic structure, metadata, and file-level indicators where available. Results should be interpreted as screening signals, not absolute proof. For use-case specific guidance, start with the AI detector guide hub, which organizes checks by industry, AI model, and content type.
Methodology & Detection Approach
- Text signals: perplexity, burstiness, repetition, sentence variation, and other stylometric patterns.
- Visual and file signals: image metadata, C2PA / Content Credentials markers, compression artifacts, file headers, and visible generation artifacts where available.
- Audio and video signals: local waveform, bitrate, duration, resolution, aspect-ratio, C2PA marker, and metadata cues where the browser can read them.
- Writing quality signals: grammar, readability, tone, keyword density, plagiarism risk, and document conversion utilities.
- Human review guidance: outputs are designed to support judgment, not replace it in academic, hiring, legal, or editorial decisions.
Authoritative Research & Standards
- NIST Multimodal Information Group — federal AI detection research
- C2PA Content Credentials Standard — industry standard for content provenance
- FTC AI Claims Guidance — consumer protection requirements
- DHS Science & Technology — Synthetic Media — federal synthetic content research
- U.S. AI.gov Initiative — federal AI policy hub
- arXiv — Computational Linguistics Research — peer-reviewed detection papers
Detection Disclaimer: No AI detector is 100% accurate. Results should be used as supporting evidence, not sole determination. Edge cases (mixed human-AI content, paraphrased AI text, novel models) can produce false positives or negatives. Use multiple tools and human judgment for high-stakes decisions like academic integrity or hiring.

Which EyeSift Tool Should You Use?
Start with the tool that matches the format you need to check. AI detection is strongest when the tool can inspect the right signals for the content type rather than forcing everything through a text-only workflow.
| Need | Best EyeSift Tool | What It Checks |
|---|---|---|
| Check an essay, article, email, or resume | AI Text Detector | Text statistics, repetition, sentence variation, and AI-writing patterns |
| Respond to an AI detector false positive | AI Detector Appeal Letter | Evidence checklist, readiness score, and editable human-review request |
| Check an image or AI art | AI Image Detector | EXIF, C2PA markers, compression clues, dimensions, and visual artifacts |
| Check a voice clip or synthetic audio | AI Audio Detector | Waveform energy, silence ratio, bitrate, and synthetic voice indicators |
| Check a video or deepfake-style clip | AI Video Detector | Duration, dimensions, bitrate, C2PA markers, aspect ratio, and generation-risk cues |
| Improve writing quality | Free Grammar Checker | No-signup grammar, spelling, punctuation, repeated-word, and confused-word checks |
| Check typos quickly | Free Spell Checker | Browser-based typo, spacing, repeated-word, and confused-word checks |
| Prepare SEO or editorial copy | Keyword Density | Keyword frequency, overuse risk, and topical focus checks |
Mixed Human + AI Content
The hardest case is mixed content: human writing that has been rewritten, expanded, or polished by AI. Treat detector output as a risk signal and inspect the highest-risk sections manually. For academic integrity, hiring, legal, or disciplinary decisions, do not rely on a single detector result as the only evidence.
Watermarks and Content Credentials
Some AI systems and media tools support watermarking or provenance standards such as C2PA Content Credentials and Google DeepMind's SynthID. Coverage is still uneven, so EyeSift treats metadata and provenance as useful evidence when present, not as a guarantee when absent.
Accuracy note: AI detection changes as generation models, editing workflows, and watermark standards evolve. Use EyeSift results to prioritize review and combine them with human judgment for high-stakes cases.
