Available Engines

Each engine is optimized for different use cases. Higher plans unlock more engines.

ServantservantHobby+

Direct Ozone undetectable full-document pass with only first-title protection.

GlimmerglimmerHobby+

Ozone humanize-clean full-document pass followed by Nuru readability polishing.

WhisperwhisperPro+

Minimal-change anti-detection with surgical precision.

AgentagentDeveloper+

Two-stage hybrid pipeline: Oxygen prepares the paper, then the Servant Ozone-undetectable engine runs on that draft (identical Servant API path).

VinevinePro+

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.

KingkingPro+

Premium maximum-capability GPTZero-targeted engine.

LunalunaPro+

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.

HumarinhumarinPro+

Multi-detector targeting engine with sophisticated humanization patterns.

PangrampangramPro+

Stylometric disruption engine targeting character-level analysis patterns.

VanguardvanguardPro+

Maximum-strength anti-detection with aggressive restructuring.

PhantomphantomPro+

Human-quirk mimicry engine targeting pattern-based AI detectors.

BetabetaPro+

Experimental multi-strategy layered anti-detection engine.

ScribescribePro+

Academic-focused anti-detection preserving scholarly integrity.

Vine 2.0vine_v2Pro+

Core orchestrator with adaptive sentence routing, selective LLM bypass, and mode-specific prompts.

Phantom 2.0phantom_v2Pro+

Refinement controller using adaptive router to guide King prompt injection, Nuru depth, and AntiPangram intensity.

Vanguard 2.0vanguard_v2Pro+

Hierarchical intelligence layer using adaptive router for document + sentence level routing with rewrite profiles.

Apex 1apex_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 Miniapex_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 Fastapex_fastPro+

Parallel 8-stage engine: same adaptive LLM rewriting as Apex Mini, but processes ALL sentences at once instead of batches.

Apex Premierapex_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.
