💰 Pricing & Billing Model

• Price: $6.00 per 1,000 checks ($0.006 per analyzed text check).
• Billing Type: Pay-per-usage / Pay-per-result — you only pay for successful detection scans.
• No Hidden Compute Overhead: Fast execution with ultra-low memory footprints.

🚀 Key Features

• Dual AI Detection Engines: Combines deep neural analysis from Detector.io and Winston AI for maximum classification precision and redundancy.
• Sentence-by-Sentence Breakdown: Returns exact sentence highlights (startIndex, endIndex, score, label) showing exactly which sentences are flagged as AI or human.
• Overall AI Score & Verdict: Delivers an aggregated overallScore (0–100%) and clear categorical verdict (ai, human, mixed).
• Multi-Model LLM Classification: Accurately classifies text generated across all major foundation models including OpenAI (GPT-4o/mini, GPT-5, o1), Anthropic (Claude 3.5 Sonnet), DeepSeek-R1, Google Gemini, and Meta Llama 3.
• Short-Text Auto-Adaptation: Automatically adapts single sentences and short paragraphs so your scans never fail due to word count constraints or minimum character limits.
• Flattened Dataset & Key-Value Output: Automatically saves the full JSON payload to Key-Value Store (OUTPUT) and outputs structured data rows to the default dataset.
