Available Engines
Each engine is optimized for different use cases. Higher plans unlock more engines.
servantHobby+Direct Ozone undetectable full-document pass with only first-title protection.
glimmerHobby+Ozone humanize-clean full-document pass followed by Nuru readability polishing.
whisperPro+Minimal-change anti-detection with surgical precision.
agentDeveloper+Two-stage hybrid pipeline: Oxygen prepares the paper, then the Servant Ozone-undetectable engine runs on that draft (identical Servant API path).
vinePro+10-phase sequential LLM rewrite using GPT-4o mini. Each phase chains output to next input. 46% min change per phase, 75% cumulative target. Paragraph structure preserved.
kingPro+Premium maximum-capability GPTZero-targeted engine.
lunaPro+Ultra-fast local humanizer using V2 synonym engine, word kill, and connector variation. No API keys or network needed. Processes 5000 words in 3-5 seconds.
humarinPro+Multi-detector targeting engine with sophisticated humanization patterns.
pangramPro+Stylometric disruption engine targeting character-level analysis patterns.
vanguardPro+Maximum-strength anti-detection with aggressive restructuring.
phantomPro+Human-quirk mimicry engine targeting pattern-based AI detectors.
betaPro+Experimental multi-strategy layered anti-detection engine.
scribePro+Academic-focused anti-detection preserving scholarly integrity.
vine_v2Pro+Core orchestrator with adaptive sentence routing, selective LLM bypass, and mode-specific prompts.
phantom_v2Pro+Refinement controller using adaptive router to guide King prompt injection, Nuru depth, and AntiPangram intensity.
vanguard_v2Pro+Hierarchical intelligence layer using adaptive router for document + sentence level routing with rewrite profiles.
apex_onePro+An evolution of Apex Mini tuned specifically for maximum reading quality, natural explanatory flow, and strict original tense preservation. Powered by DeepSeek V3 with GPT-4o-mini fallback.
apex_miniPro+8-stage adaptive engine: LLM paper analysis → dynamic protection → risk routing → 150-prompt dictionary rewriting → quality gate. No fallback to original — always rewrites with different persona prompts.
apex_fastPro+Parallel 8-stage engine: same adaptive LLM rewriting as Apex Mini, but processes ALL sentences at once instead of batches.
apex_premierBusiness+8-stage adaptive engine with 150-prompt dictionary and per-sentence risk routing — powered by DeepSeek V3 with GPT-4o-mini fallback. Delivers richer contextual rewrites with superior instruction-following.
