How does AI detection work?

AI detection analyzes text using statistical methods like perplexity analysis (measuring how predictable the text is), burstiness analysis (measuring sentence-level variation), and neural classification. Human writing tends to be more varied and unpredictable, while AI text is more uniform and statistically optimal.

Is EyeSift really free?

Yes, EyeSift is 100% free with no signup required. There are no word limits, no premium tiers, and no hidden fees. We are supported by contextual advertising.

How accurate are AI detectors?

EyeSift achieves 75-85% accuracy on standard benchmarks. No AI detector is 100% accurate. Accuracy varies based on content type, AI model used, text length, and whether the text has been paraphrased or edited. We are transparent about our accuracy because we believe honesty builds trust.

Can AI detectors detect ChatGPT?

Yes, EyeSift can detect content from ChatGPT (GPT-4, GPT-4o, GPT-4.5), Claude, Gemini, DeepSeek, Grok, Copilot, and other major AI writing tools. Each model has distinct statistical patterns our analysis identifies.

What about false positives?

False positives (flagging human text as AI) occur at a rate of approximately 6-15% depending on the text type. Non-native English writing, heavily edited text, and formulaic content are more likely to trigger false positives. EyeSift provides confidence scores and sentence-level highlighting to help users assess results contextually.

Can AI detection work on short texts?

Detection accuracy decreases significantly for texts shorter than about 150 words. Short samples do not contain enough statistical signal for reliable analysis. We display warnings for short inputs and recommend analyzing at least 250+ words for best results.

Does EyeSift store my content?

No. EyeSift processes content in real-time for analysis only. Your text is never stored, logged, or used for training purposes. Content is processed and immediately discarded after generating results.

Can AI detectors be fooled?

Yes, AI detection is not foolproof. Paraphrasing tools, adversarial prompting, and human editing can reduce detection rates. However, our ensemble approach combining multiple detection methods makes evasion significantly harder than defeating any single method.

What types of content can EyeSift analyze?

EyeSift is a multi-modal platform that can analyze text, images, video, and audio for AI-generated content. Our text analyzer is our most mature tool, while image, video, and audio analysis use metadata, spectral, and pattern analysis techniques.

Is AI detection admissible in court?

AI detection results are generally not sufficient as sole evidence in legal proceedings. They are informational tools best used alongside human judgment, contextual assessment, and other verification methods. Some courts have accepted AI detection as supporting evidence, but legal standards vary by jurisdiction.

How does EyeSift compare to GPTZero?

Both tools detect AI-generated text, but EyeSift is completely free with no word limits and supports multi-modal detection (text, image, video, audio). GPTZero offers 5,000 chars free then $10-24/month. EyeSift provides transparent 75-85% accuracy reporting, while some competitors claim higher accuracy without publishing methodology.

Can AI detection distinguish between different AI models?

To some extent, yes. Different AI models produce text with distinct statistical fingerprints. For example, ChatGPT output tends to differ from Claude output in sentence structure and vocabulary patterns. However, as models converge in quality, distinguishing between specific models becomes harder.

Why do different AI detectors give different results?

Each AI detector uses different algorithms, training data, and confidence thresholds. A text that scores 80% AI on one tool may score 40% on another. This is why we recommend using AI detection as one data point, not the sole basis for decisions.

Does AI detection work for non-English languages?

EyeSift is primarily optimized for English text. Detection accuracy for other languages is lower and varies by language. Languages with large AI training datasets (Spanish, French, German, Chinese) tend to have better detection than less common languages.

What is perplexity in AI detection?

Perplexity measures how predictable text is to a language model. Low perplexity means the text follows highly predictable patterns (common in AI text), while high perplexity means unexpected word choices (common in human writing). EyeSift measures perplexity at token, sentence, and paragraph levels.

What is burstiness in AI detection?

Burstiness measures the variation in sentence complexity within a document. Human writers naturally alternate between short and long sentences with varying complexity. AI tends to produce more uniform sentence structures. Low burstiness is a signal of AI generation.

Can teachers use EyeSift for academic integrity?

Yes, EyeSift is widely used by educators. It provides sentence-level analysis showing exactly which portions of text are flagged, helping teachers have informed conversations with students. We always recommend using detection as one tool alongside professional judgment, not as an automated judge.

Does paraphrasing fool AI detectors?

Paraphrasing can reduce detection rates by 15-25 percentage points. However, heavily paraphrased AI text often retains some statistical signatures that detectors can identify. The more extensive the paraphrasing, the harder detection becomes, but the text also becomes more "human" in the process.

What is the minimum text length for reliable detection?

We recommend at least 250 words for reliable results. Texts of 150-250 words produce less certain results, and texts under 150 words may not contain enough statistical signal. Our tool displays warnings for short inputs and adjusts confidence levels accordingly.

Can AI-generated images be detected?

Yes, AI-generated images from tools like DALL-E, Midjourney, and Stable Diffusion leave detectable artifacts including GAN fingerprints in the frequency domain, missing or synthetic EXIF metadata, inconsistent noise patterns, and semantic anomalies like impossible shadows or anatomical errors.

What are deepfakes and can EyeSift detect them?

Deepfakes are AI-generated or AI-manipulated videos and audio that depict people saying or doing things they never did. EyeSift can analyze videos for temporal inconsistencies, facial landmark anomalies, audio-visual sync issues, and compression artifacts that indicate manipulation.

Is it ethical to use AI detection?

AI detection is ethical when used responsibly. Key principles include: using detection as one input in decision-making (never as an automated judge), being transparent about its limitations, avoiding punitive decisions based solely on detector output, and considering the impact on vulnerable groups like ESL students.

How often is EyeSift updated?

Our detection models are re-evaluated monthly against the latest AI-generated content. We update algorithms when accuracy degrades, and we retrain on samples from new model versions. Our accuracy figures are updated to reflect current performance, not historical results.

Does EyeSift have an API?

EyeSift currently operates as a web-based tool. We are exploring API access for enterprise users. Contact sales@eyesift.com for enterprise partnership inquiries.

Can AI detection work on code?

AI detection for code is less reliable than for natural language text. Code has inherently more structured and formulaic patterns, making it harder to distinguish between human and AI-written code. Our tool is optimized for natural language content.

What happens to my data after analysis?

Nothing. Your submitted content is processed in real-time and immediately discarded. We do not store analyzed text, analysis results, or any derived data. Our privacy policy details our data handling practices.

FAQ

Can AI voice clones be detected in 2026?▼

YES, with significant caveats. Detection accuracy 2026: PINDROP (industry leader) 88.4% on raw cloned audio. Resemblyzer (open-source) 82%. AI or Not Voice 79%. WHY DETECTION IS HARDER THAN TEXT: (1) Audio compression (phone calls 8kHz vs studio 48kHz) destroys spectral fingerprints. (2) Background noise + overlapping speech degrade signals. (3) Voice cloning improvements faster than detection. (4) Same person can sound different across sessions (illness, mood). DETECTION TECHNIQUES: SPECTRAL ANALYSIS — looks for AI-generated artifacts in frequency domain. Newer models reduce these. PHONEME TIMING — AI voices have unnaturally consistent phoneme durations. SPEAKER VERIFICATION — match against known voice prints. NEURAL ANTI-SPOOFING — ML classifier trained on cloned vs real. PRACTICAL ACCURACY: 60-80% on real-world phone audio (lower quality, compressed). 85-92% on studio-quality audio. PHONE SCAM accuracy: 50-65% — significantly lower due to compression. ELEVATED FALSE POSITIVE on legitimate compressed/old recordings. RECOMMENDATION 2026: Pindrop for enterprise (banks, insurance). Resemblyzer + custom for tech teams. Sensity multi-modal for video+audio. AI or Not Voice for casual one-off checks.

ABUSE PREVENTION: ElevenLabs requires (a) email verification, (b) "I have rights to this voice" attestation, (c) watermarking on premium tiers, (d) banning detected misuse accounts. STILL ABUSED: Bad actors create accounts with stolen credit cards, run cloning, abandon account. ElevenLabs cooperates with law enforcement on subpoenas. EVASION TECHNIQUES known: (1) Generate via ElevenLabs → record output via different device → upload to target platform = no watermark. (2) Run cloned audio through pitch shifting, reverb, EQ → degrades watermark. WATERMARK STATUS 2026: ElevenLabs uses cryptographic watermarking on generated audio. Detection rate ~85% if audio not heavily edited. Heavy editing drops to 30-40%. Industry-wide push for stronger audio provenance (similar to C2PA for images).

How do banks defend against voice deepfake scams?▼

Bank voice fraud defenses 2026: (1) MULTI-FACTOR — voice ALONE no longer sufficient for high-value transfers. SMS + email + app push all required. (2) CALLBACK PROTOCOL — bank calls customer at registered number. Catches voice clones from spoofed callerID. (3) BIOMETRIC VOICEPRINT — registered voice print compared to caller. Pindrop + Nuance market leaders. (4) AI ANTI-SPOOFING — Pindrop deepfake detection embedded in call routing. 88% accuracy. (5) BEHAVIORAL ANALYTICS — login patterns, transaction velocity, geographic. Anomalies flag for human review. (6) REQUIRED SECURITY QUESTIONS — beyond identifiers (DOB, SSN are publicly available). Personal questions only customer + close family know. (7) WIRE TRANSFER CONFIRMATION — high-value transfers require 24-72 hour holds + secondary verification. Eliminates "urgent transfer now" pressure. (8) STAFF TRAINING — bank reps trained to recognize voice clone red flags: unusual urgency, pressure, requesting unfamiliar transfer destinations. (9) CUSTOMER EDUCATION — banks send fraud alerts about voice scam patterns. (10) ZERO-TRUST POLICY — no transaction verification without 2+ factor. JP MORGAN, USAA, BANK OF AMERICA ALL adopted enhanced voice fraud protection 2024-2025 after $5B+ industry losses. Per Aite-Novarica 2025 report: 72% of major banks now use voiceprint biometrics. CUSTOMER SHOULD: enroll voiceprint at bank. Set up callback verification. Ask bank about deepfake-specific protections. NEVER authorize transactions on cold calls regardless of caller ID.

What are detect AI voice in real-time during a call?▼

Real-time AI voice detection 2026: ENTERPRISE TOOLS — Pindrop (call-routing-level analysis), Reality Defender, Sensity, Hive AI Voice. ACCURACY 70-88% real-time vs 80-92% post-hoc. CONSUMER TOOLS — limited. McAfee Project Mockingbird (browser extension, mobile app) — flags suspect calls. Truecaller AI Verify (Premium $4/mo) — detects AI voices in real-time on Android. AT&T ActiveArmor — scam detection beta with AI flag. SMARTPHONE APPS 2026: many phone manufacturers building in real-time deepfake detection. Samsung Galaxy AI (S25/S26) includes "Deepfake Caller Alert." Apple iOS 19 (rumored) includes real-time AI voice flagging. Google Pixel Tensor G5 chip includes on-device deepfake detection. CONSUMER-GRADE accuracy: 60-75% (phone audio compression challenges). USE CASE: alert when suspect, NEVER absolute trust. RECOMMENDATIONS: (1) Banks should deploy Pindrop or equivalent before customer transactions. (2) Enterprise should integrate detection into IVR + call analytics. (3) Consumers — install McAfee Mockingbird (free) + Truecaller. Don't trust caller ID alone. (4) For high-stakes calls (finance, sensitive personal info), CALLBACK to verified number — defeats voice cloning. WHAT NOT TO DO: rely solely on real-time detection. False negatives cost money. Always have fallback verification for high-value scenarios.

How do I protect my own voice from cloning?▼

Protect your voice from cloning 2026: WHAT MAKES YOU VULNERABLE: (1) Public audio — podcasts, YouTube videos, social media voice posts. 30 seconds of clean audio = clone quality. (2) Voicemail greetings — public available. (3) Conference calls posted online. (4) Court depositions, public speeches, interviews. CELEBRITIES + EXECUTIVES at high risk — extensive public audio. PROTECTIVE MEASURES: (1) AVOID giving voice samples to "voice phishing" calls (scammers request "Yes" / "I confirm" recordings to splice). (2) DON'T post voice clips on public TikTok / YouTube without C2PA Content Credentials watermarking. (3) USE voice biometric security at bank (registers your voiceprint with the institution). (4) ESTABLISH SAFE WORDS with family. If "you" call asking for emergency money, family asks for code word AI scammer doesn't know. (5) ENROLL in DEEPFAKE PROTECTION SERVICES — McAfee Online Protection, Norton 360 with Deepfake Defense, ID Care. (6) MONITOR voice usage — Google your name + "voice clone" + "AI voice" to catch unauthorized clones. (7) LEGAL — DMCA / right of publicity claims if voice cloned without consent. State laws vary (TN passed ELVIS Act 2024). LEGAL LANDSCAPE 2026: TENNESSEE ELVIS Act (March 2024) — protects voice as IP. CALIFORNIA SB 942 (2024) — discloses AI usage. NY SAG-AFTRA contract (2024) — actor consent required for voice replication. FEDERAL: bipartisan NO FAKES Act introduced 2024, may pass 2026. PRACTICAL: assume voice will be cloned eventually. Build verification systems that don't depend solely on voice.

Is voice deepfake illegal in 2026?▼

Voice deepfake legality 2026: ILLEGAL when used for: (1) Fraud (identity theft, financial scams). Federal wire fraud + state fraud laws apply. (2) Defamation (false statements harming reputation). (3) Impersonation in commercial context (right of publicity). (4) Election interference (FCC ruled AI voice in robocalls illegal Feb 2024). (5) Non-consensual intimate content (NCII) — federal NDII laws + state revenge porn laws. (6) Stalking + harassment. SPECIFIC LAWS 2026: TENNESSEE ELVIS ACT (March 2024) — protects voice + likeness as intellectual property. Strongest state law. CIVIL + criminal penalties. CALIFORNIA SB 942 (2024) — requires disclosure of AI-generated content in commercial use. Civil penalties. NEW YORK + WASHINGTON STATE — similar civil right of publicity laws. EU AI ACT (2025) — requires AI labeling. Penalties up to 7% global revenue. FEDERAL — NO FAKES Act introduced bipartisan 2024-2025. Status as of April 2026: passed Senate, House version pending. Likely passes 2026. Would create federal civil right of publicity for voice + likeness. ENFORCEMENT REALITY 2026: Most cases STILL prosecuted under existing fraud + identity theft laws. Voice cloning is the TOOL, fraud is the CRIME. Sophisticated international scammers face limited extradition. CIVIL SUITS more practical than criminal for victims. SETTLEMENTS becoming common: ElevenLabs settled multiple privacy + IP claims 2024-2025. PRECEDENT-SETTING: Drake/Weeknd "Heart on My Sleeve" AI song (2023) — Universal got DMCA takedown but unclear final IP rules. RECOMMENDATION: VICTIMS OF VOICE FRAUD — file FBI IC3 report, state AG complaint, civil suit. Consult IP attorney. Document timeline + losses meticulously.
