Risk Categories
Content Detection Domains

Nine risk categories.
Every linguistic surface.

Exhaustive coverage across core linguistic risk categories using hyper-specific detection vectors. Configure thresholds independently per category and per scenario.

Sexual
Detect explicit material and suggestive narratives (soft porn) with multi-level severity scoring for granular moderation policies.
TIER · CRITICAL
Hate Speech
Recognize slurs, defamation, and targeted attacks based on protected characteristics or personal identity across diverse contexts.
TIER · HIGH
Prohibited Goods
Flag the promotion of illicit weapons, narcotics, gambling, and counterfeit services or fraudulent behaviors.
TIER · CRITICAL
Child Safety
Prevent grooming, exploitation, and exposure to age-inappropriate content to ensure a secure environment for minors.
TIER · CRITICAL
Spam
Detect and mitigate repetitive content, gibberish, and low-effort posts to foster authentic interactions.
TIER · MODERATE
PII Protection
Automatically detect and redact unauthorized sharing of personal data — IDs, bank details, phone numbers, private addresses.
COMPLIANCE
Illicit Advertising
Block unauthorized promotions and contact-harvesting attempts — social IDs, phone numbers, QR codes embedded in text.
TIER · HIGH
AI Safety
Hardened defense against LLM manipulation — prompt injection, jailbreaking, and deceptive role-play attacks.
LLM HARDENING
Symbolic & Emoji
Decipher the hidden intent behind complex emojis, character-based symbols, and evasive text variations.
SEMANTIC DECODE
Core Engine

Built for the language
of evasion.

Modern text risks aren't in keywords. They're in homophones, leetspeak, zero-width unicode, emoji combinations, and adversarial prompts. Our engine is designed for exactly that fight.

ANTI-EVASION FSA

Catching the uncatchable. By design.

Leveraging FSA (Finite State Automaton) algorithms, we identify complex text variants — homophones, character substitutions, pinyin, zero-width unicode — designed to bypass traditional rules. Our defense is positioned at the very front of the risk cycle, neutralizing evasion attempts before they escalate.

  • Unicode normalization catches zero-width and look-alike attacks
  • Phonetic matching handles homophones and pinyin substitution
  • FSA matching scales to millions of evasion patterns at low latency

99%+ ACCURACY · NLP STACK

FastText + HMM + CRF + Word2Vec. Fused.

Our engine integrates and innovates upon a diverse stack of cutting-edge NLP technologies: FastText, HMM, CRF, and Word2Vec. By fusing multiple models, we deliver a market-leading detection accuracy of 99%+, ensuring your platform remains clean without sacrificing user experience.

  • FastText for fast multilingual classification at scale
  • CRF for entity extraction (contact info, addresses, IDs)
  • Word2Vec embeddings for semantic similarity to known risks
  • HMM for sequential pattern recognition across long messages

AI SAFETY · LLM HARDENING

Hardened defense for the LLM era.

Generative AI platforms face a new class of risks. Our text engine includes a dedicated AI Safety layer — purpose-built to detect prompt injection, jailbreaking, role-play exploits, and deceptive instruction-following attacks that bypass standard moderation. Critical for chatbots, AI companions, and AIGC platforms.

  • Detection runs on both user input and LLM output
  • Pattern library updated continuously from real-world attacks
  • Context-aware — distinguishes legitimate role-play from exploits

Leveraging FSA (Finite State Automaton) algorithms, we identify complex text variants—such as homophones, character substitutions, and pinyin—designed to bypass traditional rules. Our defense is positioned at the very front of the risk cycle, neutralizing evasion attempts before they escalate.

Beyond Text: Symbolic & Emoji Decoding

Modern risks aren't just in words. Our engine decodes the semantic intent behind emojis and special symbols, unmasking hidden harassment, illicit advertisements, and malicious lead diversion (e.g., hidden contact info) that others miss.
