How to read these scores

Each detector returns a human-likelihood on a common 0 to 1 scale, where 1 means it judged the text human-written and 0 means it flagged it as AI. On these pages a verdict counts as passed when that score is at least 0.50, the midpoint of the detector's own scale. That threshold exists only to draw the chips: the bypass rate on the leaderboard is the mean of each test's median score across the 5 detectors, a continuous number, so a tool's pass count and its bypass rate will not be the same figure.

Meaning is the input↔output embedding cosine and readability is a language-model writing-quality rating, both published per test in tests.json. Words is the output's length as a multiple of the input's; the scoring code penalizes ratios above 1.40 or below 0.60. Full definitions live in the methodology.

Humanized outputs

Ordered by how many detectors each rewrite passed; ties fall back to this cycle's rank. Each block shows what the tool returned and how the 5 detectors scored it.

# Cover letter for mid-career data scientist Dear Hiring Manager, I wanted to reach out and let you know that I'm interested in the senior data scientist position you're advertising. With 7+ years of experience as a data scientist and taking raw data and turning it into actionable insights for businesses, I think I could be a valuable addition to your data science group. For my entire career, I've worked on solving problems with machine learning. For example, I developed a predictive model for customer churn at TechCorp analytics that resulted in a reduction of 23% in lost customers and generated approximately $4.2 million in retained revenue annually. I also built an end to end recommendation system (using collaborative filtering and deep learning) for one of their platforms that produced a 35% increase in engagement. I've had extensive experience working on all aspects of the data science pipeline. As such, I'm proficient in both R and python, as well as sql. Additionally, I use tensorflow, pytorch and scikit learn extensively for building high-quality production models. I have successfully implemented these types of models on aws and gcp and used tools like docker/kubernetes/mlflow to build scalable and repeatable pipelines. In terms of the soft skills required to work effectively as a data scientist, I believe I do a good job of connecting what we can do with the questions that are being asked by stakeholders. I've spoken to c suite executive members, mentored junior data scientists and been able to collaborate with other teams (product/eng/mktg). For example, when I was at my previous employer, I created a framework for "best practice" for data science to streamline deployments of models and reduce model deployment times by 40%. This helped increase productivity by 25% among 5 concurrent project teams. One reason I find this particular opportunity appealing is the emphasis on innovation through data science and artificial intelligence. It fits with my desire to build systems that provide tangible value. I'd love to take advantage of your organization's growing investment in machine learning technology and help enable informed decisions through large-scale analysis. I completed a master's in statistics at state university and continue to develop professionally through certificates in deep learning and cloud architecture. I also write blogs and present at conferences on topics related to data science and open source software. Thank you for reviewing my submission. I look forward to discussing how my background and perspective fit with your team's objectives. Sincerely, [Your Name]

Dear Hiring Manager, I am writing to express my strong interest in the Senior Data Scientist position at your organization. With over seven years of experience transforming complex datasets into actionable business insights, I am excited about the opportunity to contribute my technical expertise and strategic thinking to your data science team. Throughout my career, I have specialized in developing machine learning solutions that drive measurable business impact. In my current role at TechCorp Analytics, I led the development of a customer churn prediction model that reduced attrition by 23%, generating an estimated $4.2 million in retained annual revenue. I also architected an end-to-end recommendation engine using collaborative filtering and deep learning techniques, which increased user engagement by 35% across our platform. My technical proficiency spans the full data science stack. I am highly skilled in Python, R, and SQL, with extensive experience using TensorFlow, PyTorch, and scikit-learn for building production-grade models. I have deployed solutions on AWS and GCP, utilizing tools like Docker, Kubernetes, and MLflow to ensure scalable, reproducible workflows. My expertise extends to statistical modeling, natural language processing, time series forecasting, and A/B testing methodologies. Beyond technical skills, I pride myself on bridging the gap between data science and business strategy. I have presented findings to C-suite executives, mentored junior data scientists, and collaborated cross-functionally with product, engineering, and marketing teams. At my previous company, I established a data science best practices framework that reduced model deployment time by 40% and improved team productivity across five concurrent projects. What particularly draws me to your organization is your commitment to leveraging data science for innovative solutions in your industry. Your recent initiatives in AI-driven personalization align perfectly with my passion for building intelligent systems that create real value. I am especially eager to contribute to your expanding machine learning infrastructure and help shape data-driven decision-making at scale. I hold a Master's degree in Statistics from State University and have continued my professional development through certifications in deep learning and cloud architecture. I am also an active contributor to open-source data science projects and regularly share insights through technical blog posts and conference presentations. I would welcome the opportunity to discuss how my experience and vision align with your team's goals. Thank you for considering my application. I look forward to speaking with you soon. Sincerely, [Your Name]

Hi there, I’m reaching out because I’m genuinely interested in the Senior Data Scientist role you have open. After spending seven years knee-deep in data — turning messy datasets into business wins — I’m excited at the thought of jumping in with your team and adding my technical know-how and big-picture perspective. Let me give you a snapshot of what I’ve been up to. At TechCorp Analytics, I spearheaded a project to predict customer churn. The model I built dropped attrition by 23% and saved the company about $4.2 million a year. That was a huge win. I also built a recommendation engine from scratch, pulling in collaborative filtering and deep learning, which boosted user engagement on our platform by 35%. I don’t just dabble — I know the full data science toolkit inside and out. Python, R, SQL? Check. I’ve pushed production models using TensorFlow, PyTorch, and scikit-learn. I get solutions running on AWS and GCP, and I use Docker, Kubernetes, and MLflow to keep workflows scalable and reproducible. I’ve got solid experience with statistical modeling, NLP, forecasting, and A/B testing too. But honestly, what drives me is bridging data and business. I’ve presented to execs, trained junior scientists, and worked closely with product, engineering, and marketing. At my last gig, I rolled out a framework for best practices that cut model deployment time almost in half and made the team way more productive. What makes your company stand out to me is your push for innovative, AI-powered personalization. That’s right up my alley — building systems that actually make a difference for users. I’m eager to help you scale your machine learning infrastructure and bring even more data-driven decisions to the table. I’ve got a Master’s in Statistics from State University, and I keep learning — picking up certifications in deep learning and cloud architecture, contributing to open-source projects, and sharing ideas at conferences and on my blog. I’d love to chat and see how I can help move your goals forward. Thanks for considering me, and hope to hear from you soon. Best, [Your Name]
