Instant code security scanner. Detects invisible Unicode steganography and hidden payloads. Runs entirely in your browser — nothing leaves your machine.
Detects zero-width characters, bidirectional overrides, and tag characters that can hide executable payloads in plain sight. The same technique used by Glassworm and KOI attacks in 2026.
Flags consecutive runs of 3+ invisible characters — the signature pattern of steganographic code injection. These sequences encode binary data that gets decoded at runtime via eval().
Identifies stray invisible characters from copy-paste that may not be malicious but should be cleaned from security-sensitive code. Reports exact line and column for each occurrence.
Deep AI analysis powered by GPU. Security audit, code quality review, and deployment readiness check via large language model.
