CoverSentry is a free web tool that scans a cover letter and estimates how likely it is to read as AI-generated, then gives recommendations for making it sound human. It pairs a fine-tuned detection model with a no-registration CV builder that produces ATS-friendly resumes.
Upload a PDF, DOCX, RTF or TXT file, or paste text, and receive a percentage score with a human, mixed or AI verdict in seconds.
The scanner was trained on a custom corpus of cover letters rather than generic web text, so it recognises the specific templates applicants reuse.
The detector stores nothing — documents are analysed in memory and discarded immediately, and the site does not use tracking cookies.
Each scan returns concrete rewrite suggestions aimed at the phrasing patterns that make letters read as machine-written.
由 DeepSeek-V4 与 R1 驱动的高效开源权重与托管推理 AI，token 成本极低。
依托稀疏混合专家架构（V4-Pro 为 1.6T 中的 49B 激活参数），以极低延迟与内存开销处理最多 100 万 token。
由 DeepSeek-R1 开创并融入 V3.2 与 V4 思考模式，对复杂数学、逻辑与代码调试展示逐步自校验过程。
缓存命中时，输入 token 成本降至 Flash 的每百万 0.003 美元与 V4-Pro 的每百万 0.022 美元，非高峰 UTC 时段费率再低 50%。
在 chat.deepseek.com 及 iOS/Android 上免费提供文档上传、推理模式与网页搜索，核心模型不必付费墙。
提供巨大的上下文窗口与深度的 Google 生态系整合，但对于纯推理任务感觉较不够专精。

免费 / 开源提供同等级的开源权重基础模型与多语言效能，但需要自行架构主机或第三方推理设定。
ZeroGPT is an AI content detection platform with a text AI detector, AI image and video detectors, AI humanizer, plagiarism checker, and a set of writing tools including paraphraser, summarizer, grammar checker, translator, and citation helper.
免费 / 开源Enables running open-source models locally on consumer hardware, but lacks DeepSeek's cloud-scale hosted reasoning power.
