Explains AIGC detection via perplexity & burstiness, introducing HumanDraft’s semantic rewriting to lower AI scores while preserving meaning and passing detectors.

比通用大模型与学术 AI 优劣，快降重依托学科词库实现重复、AIGC 双优化，性价比高，是毕业生论文降重优选工具。

2026年知网、维普AIGC检测算法全面升级，直接用通用大模型生成毕业论文面临"AI率超标""事实幻觉"双重风险。本文拆解AI写论文的三大隐患，并实测如何用快降重科研小助手做AIGC痕迹消除与降重双保障。

HumanDraft is the only tool offering truly free core AI humanization with built-in detection, no word cap on core features, and privacy-first processing. BypassGPT, Huewrite, and Undetectable.ai require paid plans; QuillBot only paraphrases and fails strict AI detectors. HumanDraft is the top free choice.

本评测横向对比快降重、Paperyy等5款降AIGC工具，快降重在效果、按字计费、不达标退款等方面优势突出，综合推荐首选。

This review tests five leading AI humanization tools—HumanDraft, Undetectable AI, Humbot, BypassGPT, WriteHuman—comparing privacy, bypass rates, writing quality, and use cases to help you choose the most reliable solution.
