GACS combines a global blacklist with AI pattern-scoring to flag fake websites, drainer wallets, impersonation accounts, phishing messages and pig-butchering flows — in seconds, with transparent reasoning, and free and ad-free. See how it stacks up against our dedicated website checker for a deeper single-entity report.
What our AI actually checks
- Domain age, registrar bursts, and hosting overlap with known-bad infrastructure.
- Page-template fingerprints from clusters of previously-reported scam sites.
- On-chain co-funding and approval patterns linked to known drainer wallets.
- Social-bio, follower-graph and impersonation signals across X, Telegram and TikTok.
- Message-flow patterns used in pig-butchering and recovery-scam scripts.
- Live community blacklist (every verdict cross-checks the latest victim reports).
FAQ
What is AI scam detection?
AI scam detection uses pattern-recognition models to flag fraudulent websites, social accounts, wallets, messages and phone numbers based on signals humans can't reasonably check at scale — domain age, registrar history, content fingerprints, on-chain heuristics and known-bad infrastructure overlap.
How does AI detect scams?
It combines deterministic blacklist matching (the URL or wallet is already reported) with probabilistic scoring (the page mimics a known-scam template, the wallet co-funded a known drainer, the social bio matches an impersonation pattern). GACS publishes both the verdict and the reasoning, never a black-box score alone.
Is AI scam detection accurate?
Modern detectors catch the vast majority of known-pattern scams within seconds and flag suspicious unknowns for human review. They are not perfect — a green verdict is 'no red flags found right now', not a guarantee. Always pair the scanner verdict with the basics: never send funds to strangers, never share seed phrases, never pay 'unlock' or 'tax' fees.
What's the best free AI scam detector?
GACS is free, advisory-only, and funded entirely by public donations. It covers websites, wallets, social handles, messages, phone numbers and entire payment flows in one place. No signup, no fees, no execution.
Can AI detect AI-generated scams?
Yes — increasingly that's the whole job. Generative AI has made fake exchanges, fake support agents and deepfake romance scams easier to produce, so detection has shifted to behavioural and infrastructure signals (hosting overlap, on-chain co-funding, registration bursts) that the scam content itself can't hide.
