Elevate your craft with the definitive standard in accuracy: our Precision-Milled Stainless-Steel Ruler. Engineered for professionals who refuse to compromise, this essential tool bridges the gap between workshop durability and micron-level exactness. Forged from premium, tempered stainless steel, this ruler resists corrosion, warping, and the relentless wear of daily use. Its edges are CNC-milled to…
Our Precision-Milled Stainless Steel Ruler is here, and it will change the game for anyone passionate about a craft. Traditionally, tools for workshops are extremely rugged, and measuring tools are designed to show case absolute precision. For the first time, you can have both in one tool.
Because we understand the need for a precise shop tool, we designed this ruler with professional-grade stainless steel. It will not rust or warp like traditional metals, and it will not wear down like ruling on a traditional tool steel ruler. Even the edges are milled to an extremely sharp and precise edge. Our ruler is so much more precise than a traditional tool steel ruler, that we were able to laser a very useful and extremely fine Imperial and Metric graduations on the face of the ruler. The deep graduations, combined with a satin-chrome finish and a 5" length, make readability a non-issue, especially with the studio or other artificial lights.
Plus, because our ruler is designed with a true-zero edge, you can start measuring against a wall with a flush joint. And, because it's designed to be heavy, it will help give you the control you need when measuring.
Whether you are an engineer or architect checking tolerances, or a woodworker laying out intricate joints, you can rely on our ruler to be extremely precise. You will get the same confidence and precision for every measurement you take. That's why we engineered a ruler designed to last.

Benchmark results
First of 14 overall, five places ahead of AI Humanize io
HumanizerBench is a public monthly benchmark of AI humanizers. It pays for every tool, runs each one by hand on the same prompts, and publishes all inputs, outputs, and detector scores so the results can be checked. The October 2026 cycle ran 30 samples per tool, 420 tests, and six AI detectors, with Pangram joining the panel. WriteHuman finished first of the fourteen humanizers with a composite of 74.89, its fourth cycle in a row at #1, tested on its entry-level Basic plan. AI Humanize io placed sixth at 68.24.
The head-to-head detail backs that up. WriteHuman's output passed 88.8% of the AI-detector checks to AI Humanize io's 66.5%, it scored higher on consistency across content types (94.7% vs 92.6%), and it beat AI Humanize io on all six detectors and all four content types in the comparison above. The full numbers are on HumanizerBench itself.

Detector scores
Ahead on all six detectors, with the field's top GPTZero score
Every rewrite in the benchmark is scored against six commercial AI detectors, and each output's detector score is the average of all six verdicts, so a tool has to get past every one of them to post a high pass rate. In the October 2026 cycle, WriteHuman scored higher than AI Humanize io on all six.
On GPTZero, WriteHuman posted 99.5%, the highest GPTZero score of the fourteen humanizers tested, against AI Humanize io's 70.0%. It scored 100.0% on both Winston AI and Originality.ai, the top marks in the field on each, to AI Humanize io's 89.9% and 90.2%. WriteHuman also came out ahead of AI Humanize io on Copyleaks (93.3% vs 73.6%) and ZeroGPT (89.5% vs 75.4%). Detectors disagree with each other constantly, which is why WriteHuman puts its own detector in the same view as the humanizer: you check the text against a score before you publish.

Content types
Ahead on blog, news, marketing, and discussion content
HumanizerBench breaks its scores out by content type. In the October 2026 cycle WriteHuman scored higher than AI Humanize io on all four of the content types in the comparison above: blog posts, news articles, marketing copy, and discussion posts.
News articles are the widest split, with WriteHuman at 99.2% against AI Humanize io's 60.2%. Discussion posts run 93.2% to 72.8%, marketing copy 88.2% to 66.5%, and blog posts 84.7% to 61.3%. A humanizer that holds up in one format and falls apart in the next is a tool you have to re-check every time you change what you are writing.
