Elevate your craft with the definitive standard in accuracy: our Precision-Milled Stainless-Steel Ruler.

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.

Enhance your creations with the ultimate benchmark in precision: our Precision-Milled Stainless Steel Ruler. Designed for specialists unwilling to settle for mediocrity, this indispensable tool offers the best of both worlds in terms of strength and micro-measurement. Made from high-quality stainless steel that has undergone tempering, the ruler remains resistant to rust, distortion and the impacts of continuous usage. Its edges are produced with the help of CNC milling techniques that guarantee accuracy of measurements for cutting, marking and sharpening. Unlike cheap stamped solutions that wear off over time, the rigid and clear engraving of both metric and imperial measurements is done using the laser engraving technology. The creating of this erasable graduation is easy with the help of the shiny and satin chromium coating. The hard nature of the ruler allows getting the readings directly from its zero edge which guarantees the accuracy of all vertical measurements and is very quick in taking readings on paper, wood and metal. The ruler is a must-have for all the builders who require proper measurements when designing houses and furniture.

Grow your own vegetables, one small step at a time

If you don't have the time or space for extensive gardening, growing your own vegetables can still be easy. The SproutPlan team knows how to manage garden plans to make the most of your backyard.

A plan that fits your backyard and your schedule

You can set up your garden plan using the space you have that is most convenient to you, even if it is not the traditional rectangular bed.

You will receive notifications about your plants to help you with maintenance. The notifications also include information about the proper way to perform a task to help you learn more about gardening.

No huge, complicated plans. No planting guides that you have to figure out. Just a simple way to get your family's first veggies straight from the garden.

You've got a backyard and veggie seeds. Why not?

Get your free garden plan and discover what you can grow. You can play around with your plan before you buy anything, or start when you are ready. You don't even need to enter a ton of info. Just a little plan and some will go a long way.

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.

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.
